What Is The True Cost Of A Grounded Agriculture Plane?

Screen Shot 2014-01-10 at 9.47.04 AM

It sure is fun to pull off to the side of the road and watch those agricultural planes do their work. These planes make a sweet sound as they swoop over country roads to spray a field. The lightweight plane is maneuverable and the pilot knows it. Going upside down, twists and turns are all part of the game. But most people don’t understand just how crucial the old “Ag plane” is to the business of farming crops. Continue reading What Is The True Cost Of A Grounded Agriculture Plane?

The Most Unique Planes on the Planet: Aviation Enthusiast Planes

A few days ago we talked about the mythical Pool Plane, John Travolta, and Donald Trump’s gaudy plane.  Today we talk about some of the real deal stuff, the stuff us aviation enthusiasts care about! Happy Flying!

Enough with the jet-set celebrities, here are some planes that are really unique.

sr-71-blackbird-photo-from-lockheed-martinIn the history of aviation, there have been many attempts to make it fly faster, fly higher, and be more efficient while doing it.  Some of the greatest planes started out as being “unusual.”  The SR-71 Blackbird looked like no other plane when first introduced.  The Mach 3+ aircraft was used as a reconnaissance plane because it could fly higher than any fighter and faster than surface-to-air missiles.  By the way, the engines that can carry a plane this size, that fast and that far?  They’re Pratt & Whitney, of course.

Did you ever have one of those foam toy airplanes that looked pretty good and flew?

70663main_proteus_lgWell, take two of those, take the tail off of one and the nose off the other, glue them together so you have a nose and tail with two sets of wings, then run it over with your bike a couple of times and it will resemble the last of our unique planes worth mentioning.  The Proteus was designed by Burt Rutan, president of Scaled Composites LLC, based in Mojave, Calif.  This very unusual looking aircraft is intended for very high flight (59,000 to 65,000 feet) at up to 18 hours a flight.  Designed to be a telecommunications relay platform, other uses are seen as use for scientific atmospheric study, launching small satellites and earth monitoring.  Designed to be usable from many airports with little support, it can be flown by two pilots or remotely.

Going faster, further and longer is the dream of many airplane designers.

It is little wonder that many of them begin with a Pratt & Whitney power-plant.  Pratt & Whitney is the most dependable engine in the world, with some models that can perform for up to 8000 hours before required overhaul.  That is like driving a car engine more than a half a million miles.  At Covington Aircraft, we specialize in the PT6A turbine and R-985 and R-1340 radial engines for corporate, commercial, and agricultural aircraft.  We are also a Pratt & Whitney Canada authorized Distributor and Designated Overhaul Facility.  We carry a complete line of engine parts and strive to give you the fasted turnaround at a competitive price.  Committed to Integrity, Dependability, Affordability, and Quality Service, Covington Aircraft has been keeping planes flying since 1972 and is a full-service, world-class facility.

The Most Unique Planes on the Planet: Celebrities

There are some great planes out there, such as the War Birds flown by Clyde Zellers, but these planes truly take the cake! This is the first post of two on some of the most unique planes on the planet! Enjoy, and let us know if you have found some crazy planes by leaving a photo on our Facebook page!

When it comes to unique planes, some things aren’t practical and some things are impossible.

airplane-shaped-poolThere has been a rumor about a plane owned by someone so wealthy that there was a swimming pool onboard.  Sadly, research has turned up no mention of such a plane.  While it does spark the imagination, one has to consider logistics of such a feature.  The pool would have to remain empty until level, steady flight could be established, and there could be no maneuvering of the plane during use. If the plane experienced turbulence, the pool would have to be drained fast lest imbalance and shifting momentum create a fatal incident.  Furthermore, just the weight of any size pool would be enormous (water = 8 pounds per gallon).  A large bathtub may be more likely, but a pool sounds as practical in a large jet aircraft as a retractable sunroof.  There are, however, planes out there with some incredible features.

Celebrity owned aircraft.

Lumping celebrities with billionaires only seems fair.  If one has a billion dollars, it is hard to stay hidden for long, and people are bound to watch what you do.  The following is a short list of billionaire and celebrity owned aircraft and their special features.

Donald Trump’s $100 million jet with a reported $120 million in features.

donald-trump-jet-entertainment-center-300x203What, “The Donald” has to fly in a 43-year old Boeing 727? It’s fired!  Donald’s new, 757 has been sighted landing at LaGuardia Airport.  The 727 has been placed on the market for $8 million, but has not drawn any offers as of yet.  Mr. Trump purchased the 757 from fellow billionaire and co-founder of Microsoft, Paul Allen.  There are conflicting stories about how much of Mr. Allen’s interior remains, if any.  It is known that the jet spent a few months at a Georgia location before showing up at LaGuardia.  It has been reported that the jet features large leather swivel seating, a bedroom with two closets, a bathroom with gold sinks and fixtures, and a circular shower, flat-screen televisions and gold leaf plated seatbelt buckles.  A hard-to-miss feature is the Trump name on the sides of the plane done in 23 carat gold.

The Caribbean Cowboy’s love for airplanes and boats is legendary.

jimmy-buffet-plane-300x210Jimmy Buffett loves his planes and boats, so it is no wonder that he enjoys combining the two as an avid fan of seaplanes.  He currently owns four planes, a 1992 Dassault-Breguet Mystere Falcon 900, a 1998 Cessna Caravan 208 with floats attached, a 1941 Boeing E75 Stearman biplane, and a 1954 Grumman HU-16 named the Hemisphere Dancer.  The Grumman is the subject of his song, “Jamaica Mistaica,” which he wrote in honor of the Jamaican government who mistook his plane for that of a drug runner and began shooting at it while it was taxiing.  His passengers, Island Records producer Chris Blackwell, co-pilot Bill Dindy, U-2’s Bono, and Bono’s wife and children were unhurt, as was Jimmy.  The plane escaped with only a few new air inlet ports.

One cannot talk about planes and celebrities without mentioning John Travolta.

The planes belonging to John Travolta may not have all the intricate attention to lavish detail that some of the others have, but that isn’t what anyone talks about when his planes are mentioned.  What they talk about is where he keeps his planes.  John can wake up at home in the morning, have his breakfast, kiss the wife and kids, walk out to the hanger, climb in the cockpit and travel to his work destination.  While this may be true for some lucky others, there are few for whom it is a Boeing 707-100 and a vintage Gulfstream G-2.  By the way, if you look up pictures of his house, the control tower over the dining room is reported as being a mock-up.

Check the next post as we get away from the celebrity talk and get down to some very unique planes! As always, if you ever need your own plane engine looked at, be sure to stop by Covington Aircraft’s website, and give us a call!

Pratt & Whitney PT6A Emergency AD Issued


September 15, 2011


Pratt & Whitney PT6A Emergency AD Issued

pw-pt6aOn Sept. 15, 2011, the FAA published an Emergency Airworthiness Directive (EAD) for certain Pratt & Whitney PT6A engines. The emergency AD, numbered 2011-20-51, was prompted by failures of certain first stage reduction sun gears manufactured by Timken Alcor Aerospace Technologies, Inc. (TAATI) under a part manufacturer approval (PMA). The engines affected are PT6A-15AG, -27, -28, -34, -34AG, -34B and -36. About 80 of these gears are suspected to have the anomaly and about half have already been taken out of service. If not corrected, this condition could result in failure of the shaft portion of the sun gear which will result in engine shutdown.

The emergency AD is effective upon receipt. This AD applies to the listed engines which have had maintenance done to the power section module involving first stage reduction sun gear replacement since Feb. 3, 2010 having the TAATI sun gear, part number (P/N) E3024765, serial numbers (S/Ns) PC5-091 through PC5-176 installed. For affected engines, remove the replacement first stage reduction sun gear and the interacting planet gear within 15 operating hours or 15 days after receipt of this AD.

NAAA recommends you read the AD carefully to determine the action or actions required to comply with this Emergency Airworthiness Directive.

Great Places to Fly: North America

In our last post we covered Great Places to Fly around the world! Well today, we are going to focus on great places to fly in North America!  Again, let us know your most favorite places to fly in the North America in the comments below!

North America also shares some great destinations and scenic flight paths.

There is no shortage of great places to fly in our own back yard, either.  When one thinks about the deserts of the Southwest, the Grand Canyon, the shore of California, the mountain ranges both East and West, Niagara Falls, the Great Lakes shorelines, and the East Coast city sights, there are many places to fly and enjoy the view.  Listed below are a couple of favorites.

Ottawa, Ontario, Canada.


Airport: Ottawa/Rockcliffe Airport (YRO/CYRO), Airport-Marina Road, Ottawa, Ontario, Canada.  2 paved runways, automatic lighting, no tower.  For more information, click here.

Landing at the Rockcliffe Airport located on the South shore of the Ottawa River on the Northeast of this historic and picturesque city is a rare experience.  The airport is owned by the Canadian Aviation Museum, which is located on the site, and run by the Rockcliffe Flying Club.  Ottawa is a gorgeous city any time of year, but in the winter months, the Rideau Canal becomes the world’s longest skating rink.  With the cold Canadian air, the lights of the city and friendly faces all around, this can be one of the most wonderful experiences in life.  Landing in the Rockcliffe Airport also lands you close to the Prime Minister’s residence and only 5 miles from downtown.

Another great and scenic destination, Anchor Point, Alaska.


Airport: Homer Airport (HOM/PAHO), 210 Sterling Hwy., Homer, AK 99603, (907) 269-0767.  1 paved runway, 6701 foot, lighted, and an active commercial flight status (average of 136 flights a day in 2006), hours vary through the year

More than just a town in Alaska, is the Anchor River Lodge.  Situated at the mouth of the Anchor River and the Cook Inlet, the lodge sits on a bluff overlooking the Cook Inlet with Mount Iliamna in full view across the inlet.  The lodge suggests that first-timers to Alaska land in Anchorage and make the 3.5 hour drive down the spectacular Kenai Peninsula.  Featuring all the latest comforts you would expect anywhere, they will make sure you have the time of your life.  There is a lot to see and do in the area.  On the waterfront by the lodge is even a sandy beach.  The salmon and trout fishing are reported to be exceptional in the Anchor River.

Great places to go where the destination is only a part of the journey.

All of these destinations are sure to provide you with plenty to see on your way.  But, as always, make sure your aircraft is up to the trip.  Have your plane completely checked out before taking on a trip in unknown country.  Remember, it doesn’t matter where it happens; there are no good places to have mechanical trouble.  Give us a call. We are Covington Aircraft, and we are an authorized Distributor and Designated Overhaul Facility for Pratt & Whitney Canada.  We also perform services such as airframe inspections, scheduled maintenance, and even track your maintenance for you.  We carry a complete line of engine parts and do all we can to give you the fasted turnaround at a competitive price.  We specialize in the overhaul maintenance and repair of the PT6A turbine and R-985 and R-1340 radial engines.

Great Places to Fly: Around the World

Welcome to our “Great Places to Fly” series from Covington Aircraft. Part one will focus on great places to fly around the world.  Feel free to read our suggestions, but please leave your favorites as a comment below or reach out to us on Facebook and Twitter to leave your thoughts! So saddle up into the cock pit, pick your destination, and once you get there, relax, enjoy, read a book or two, and create some lasting memories!

The first thing you have to decide is, “Do I want a great flight, a great destination, or both?”

This world is a beautiful place.  There are few better ways to see it than from the cockpit of your own plane.  Airline traffic is set to routes; if your plane passes over something interesting, great!  Flying your own bird means that, within the parameters of your flight plan, you can make decisions on what you want to see.  There are also many fantastic destinations that are well worth the trip, whether it is for shopping, sightseeing, natural beauty, or a sportsman’s holiday, there are many places from which to choose.

Europe, in a paragraph?

To try and cover Europe, or any continent, in one paragraph is silly.  The best one can hope for is to relate ideas rather than full descriptions.  There are many great destinations and flights over, across and in the European continent.  What it comes down to is, what do you want to accomplish with your flight?  The following are a few locations and what there is to see.

Pembrokeshire_Coast_National_Park-1Pembrokeshire National Park, Pembrokeshire, U.K.

Airport: Haverfordwest (Withybush) Airport (HAW/EGFE), Fishguard Road, Haverfordwest, Pembrokeshire, SA62 4BN – 2 paved runways, 5000 and 3608 feet, no lights, no scheduled control.  Access the website here.

Pembrokeshire National Park:  Taking up a full one-third of the Welsh County of Pembrokeshire and all of the seacoast, Pembrokeshire National Park offers many activities along its rugged and scenic coastline.  There is a wealth of hotels, bed-and-breakfasts, cottages and campgrounds from which to choose.  The airport is located in the middle of the green rolling county and within easy access to all that there is to offer.

The Greek Island of Kasos.

Airport: Kasos Island Public Airport (KSJ/LGKS), Kasos, Greece – 1 paved runway, 3221 feet,  lighted, contact for control and landing fees and diplomatic clearance.

The-Greek-Island-of-KasosThe island municipality of Kasos is a collection of islands that are the southernmost islands in the Aegean Sea.  The airport is located in the main settlement of Agia Marina, which is where the majority of accommodations can be found.  Lodging can be had for very reasonable prices.  The island of Kasos is literally a mountainous island holding up the beaches that surround the shoreline.  There are even different types of beaches, ranging from large to small pebbles of many colors, to desert beaches.  The cuisine is varied and interesting due to its proximity to Crete and Italian influences.  There is little arable land on the island, much of the fare is caught fresh from the surrounding seas as well as brought in from the surrounding areas.  Off the beaten path, easily accessible and with the full Greek flavor.  The flight through the islands is some of the most picturesque in the world.

So, take your journey around the world, getting your passport stamped along the way! Remember, before you leave, make sure your engine is in tip top shape! If you ever need our services, give us a call and we are there for you!

If You Are an Aircraft Enthusiast, These Books on Aircraft Are Must-reads – 4 through 7

We gave you our top 3 books on aircraft that every aircraft enthusiast should read. Here are the final 4 in our top 7. Happy reading and let us know your favorites in the comments below!

covington-aircraft-books-on-aircraftSquawk 7700, by Peter Buffington, self-published.

This amazing book is the personal account of the author’s career as a pilot, including his early days of learning to fly, and the sacrifices, focus and emotions of being a young aviator.  If you are thinking about a career in aviation, or if you fly on airlines, this is a must-read.  This book is endorsed by Jeff Skiles, who was the first officer on U.S. Airways Flight 1549 which ditched in the Hudson River on January 15, 2009.

Aviation’s Most Wanted: The Top 10 Book of Winged Wonders, Lucky Landings, and Other Aerial Oddities, by Steven A. Ruffins, Potomac Books, Inc.

books-on-aircraft-covington-aircraft-22Besides having one of the longest titles in history, this book is a compilation of top 10 lists about aviation oddities and wonders.  For example, Will Rogers died in a plane crash in Barrow, Alaska.  At the time of the crash, he was working on an article.  The last word he typed was “death.”  This book is full of interesting, fun and bizarre history and facts, making it a must-have for any aviation buff.

The Cannibal Queen, by Stephen Coonts, Pocket Books.

Stephen Coonts is known for several books about flying.  To his credit are such well-known classics as Flight of the Intruder, Under Siege and Cuba.  In The Cannibal Queen, he turns from fiction to storytelling in this tale of flight that takes place in 1991.  It is the story of flying across the United States and touching down in each of the 48 contiguous states in a 1942 Stearman vintage biplane.  Upon completion of the book, it is highly recommended that one take a cross country flight… somewhere.  This work is magical to read and masterfully written.  Aviation enthusiasts will want to read it again and again to experience the flight.

Johnathon Livingston Seagull, by Richard Bach, Macmillan.

No writing of books on aircraft would be complete without mentioning Richard Bach.  Picking one of his books to mention above the others is a difficult task.  The book chosen was chosen as it is about flying, perhaps not in a craft, but the pursuit of excellence in doing what the main character was meant to do.  Nothing this writer knows could be more descriptive of the spirit of an aviator.  The story is about a seagull that learns to fly faster than any other.  At first it is to dive deeper into the water to catch the bigger fish, but as he continues to perfect his craft, it becomes the art of the performance that is paramount.  This is another magical read for an aviator of any age.

This list of must-reads for aviators and aviation fans is brought to you by some of the biggest fans there are.

We are Covington Aircraft, located a just south of Tulsa, Oklahoma,. centrally located to most of the country.  As a world-leading aircraft engine maintenance, repair and overhaul facility, we specialize in corporate, commercial and agricultural aircraft and are a Pratt & Whitney Canada-authorized Distributor and Designated Overhaul Facility.   Specializing in the PT6A turbine and R-985 and R-1340 radial engines, we carry a complete line of engine parts and strive to give you the fastest turnaround at a competitive price.  We even offer 24 hr Airplane On Ground (AOG) service: wherever your plane may be.  Committed to Integrity, Dependability, Affordability and Quality Service,  Covington Aircraft has been at your service since 1972.

If You Are an Aircraft Enthusiast, These Books on Aircraft Are Must-reads – Top 3 of 7

There are many, many books about aviation.

There are basically two kinds of books on aircraft.  The first kind will show things about aviation, the planes, the equipment, the pilots, etc.  These are often jam-packed with information about each item.  These books will often list many details about each plane, range, horsepower, GTW, etc.  There are books about planes in general, war planes, historical planes, strange and unique planes, to list a few.  The other type of aviation book is about flying.  It may include details about a plane, but it is the story or stories about flying that help the reader to experience what the subject person in the book is experiencing. Here are our first 3 of 7 books we will recommend in our 2 part series of books all aircraft enthusiasts should read! Feel free to tell us yours in the comment section below and tune in for the next 4!

Pilots Handbook of Aeronautical Knowledge: FAA-H-8083-25A (FAA Handbooks), Federal Aviation Staff, United States Government.


This is the official handbook published by the FAA as reference source for the FAA Knowledge Exams.  If you are a pilot, or aspire to be a pilot, everything you need to know for beginner and advanced licensing is contained in this book (or if you know a Pilot this would be a fantastic gift for them).  Some topics covered are the history of aviation, principles of flight, aircraft and engine structures, charts and graphs, performance calculations, weather theory, reports, forecasts and flight manuals.

Flight: 100 Years of Aviation, by R. G. Grant, D.H. Publishing.

If you want to know almost anything about the history of aviation, from the early pioneers to the latest in spaceflight, this is the book that will have it.  It even carries the endorsement of the Smithsonian Institute.  This book contains many great pictures and lots of information.

books-on-aircraft-covington-aircraftAir Crashes: What Went Wrong, Why and What Can Be Done About It, by Richard L. Collins, Thomasson Grant.

Thomas Edison once said, “We now know a thousand ways not to build a light bulb.”  Knowing what is wrong can go a great distance to knowing what is right.  The examination of aviation accident scenes can help pilots to understand why airplanes crash and how to avoid repeating those mistakes.

Again, these are only the first three of seven we will recommend from the folks here at Covington Aircraft. Let us know your favorite books about aviation to read below in the comments! Thanks and Happy Flying!

What Happens When Lightning Hits an Airplane? Does it Mean an Airplane Engine Overhaul?

It is estimated that every airplane in the United States commercial fleet will be struck by lightning more than once each year, although smaller, commuter type planes do not experience as many strikes because they are smaller and generally able to avoid clouds with potential lightning.  Although there have been instances of damage to aircraft due to lightning strikes, rarely does a strike necessitate an airplane engine overhaul.


In 1967, lightning sparked a catastrophic fuel tank explosion in a commercial airline.  Additional safety techniques have been added since then and aircraft are subjected to numerous sets of lightning certification tests during the design phase, further reducing the chances that a plane will need an airplane engine overhaul after a strike.  There have been small, commuter plane crashes that have been linked to lightning strikes, but few commercial incidents.

Passenger Risk

Most aircraft are made of aluminum, which is a good electrical conductor. Yet, in most cases where airplanes are struck by lightning during flight, passengers and the plane have survived without significant damage or injury.  However, there have been incidents when a plane sitting on a runway has been struck by lightning and passengers suffered minor injuries due to the strike.

airplanestruckbylightening-150x150What Happens?

When lightning strikes a plane during flight, it usually attaches to the nose or wing tip of the plane.  As the plane flies through the lightning flash, the electricity reattaches to the fuselage, and then travels through the exterior structure of the aircraft, exiting through another extremity such as the tail.  Lights may flicker or there may be short-lived interference with instruments.  In addition, passengers may notice some problems with headsets or other computer-operated equipment while the plane travels through the electrical charge.

New designs and better protection techniques have improved the way that airplanes can handle lightning strikes.  More protection for the fuel system and added skins on the plane better protect passengers and eliminate the need for airplane engine overhaul.  If you need any further information contact Covington Aircraft for any airplane engine overhaul needs!
