Aviation Engine Service Expert: David Hamilton

A discussion with an expert in airplane overhaul and maintenance and aviation engine service

IMG_60232David Hamilton knows a thing or two about aircraft repair.  As a teenager, he began working for Covington Aircraft part-time, helping them with their aircraft engine overhaul and aviation engine service business.  Now, over 25 years later, David is the Vice President and Operations Manager of the Covington Aircraft Engines Turbine Division.  But he isn’t focused on the past; he’s focused on the future of airplane maintenance, repair and overhaul.  Here’s an interview with David himself:

Walk us through a typical day.  What does your job entail now, and how has it changed from when you started?

David: “I started working part-time on overhauled aircraft engines when I was 15.  Covington is the only place I have ever worked.  Now, my job consists of organization of personnel, materials, facilities and parts to supply the needs and requirements of our customers’ work orders. I coordinate jobs through our facility for those same customers. I arrange purchases and sales of engines for our facility, coordinating exchanges, overhauls and repairs to meet any changing needs our customers may have.”

Where do you see Covington Aircraft going in the next 5 years?

David: “I see us growing in the PT6A market, as our relationships expand in the corporate and military markets. I also believe we will continue to be a leader within the AG market, supporting our faithful customer base. As the AG market moves more toward larger engines, I believe we will become the premier overhaul and maintenance shop to meet their needs. We owe the AG market a lot, not just in our customer’s faithfulness but for the lessons that will serve us well as we go after new business outside that market. We have a strong desire to grow, but not at the cost of our current customer base.

Being very customer-oriented, I believe the lessons we have learned in the AG market, concerning AOG situations and personal attention to individuals, are exactly what the Corporate and Military Markets are looking for. We intend to meet and exceed those expectations.”

Top 3 Overhauled Aircraft Engines at Covington


There are many different types of aircraft coming and going, our skilled mechanics are constantly on the move, and so they really helped us out coming up with our list.

1. Agricultural Aircraft

An agricultural aircraft has been built or converted for agricultural uses, usually aerial crop spraying or fertilizing, and sometimes they are used for hydro-seeding.  Most of these agricultural aircraft are fixed wing models. Agricultural aircraft enable food production and fiber cultivation, which helps feed and clothe people around the world.  Agricultural aviation is extremely vital to the world’s food sources.

2. Bush or “Back Country” Aircraft

Bush planes use a variety of aircraft but there are a few more common aircraft types, such as: the DeHaviland Beaver and the Single Engine Otter. These flight models provide passenger comfort as well as hauling huge freight loads to remote areas.  Bush planes are usually used when there is no other way to get supplies in to a secluded area.

3. WarBird Aircraft

WarBird aircraft is usually designated by type: fighter, trainer, bomber, jet, etc. and then by manufacturer. They are often considered to be luxury items, but they also provide a great link to our nation’s aerial history.  WarBird aircraft are typically owned and maintained by individuals, museums, and/or flying clubs which are committed to honoring the legacy of our aviators. War Birds are commonly seen at air shows and many of them are still in excellent flying conditions.


Overhaul and Maintenance Expert: Ron Hollis

Ron-in-Hangar-300x225Ron Hollis is a man who’s been around and seen a lot of things in his 28+ years of experience in airplane overhaul and maintenance at Covington Aircraft.  He learned his trade working in Covington’s Radial Division as well as a stint working on his own as a Field Service Provider, selling Covington overhauled aircraft engines and accessories.  Ron came back to Covington in 1988 and assisted Covington Aircraft in an effort to diversify its overhaul services.  Research that he helped to conduct led the company to choose the Pratt & Whitney Canada PT6A series engine as an addition to its existing R-985 and R-1340 overhaul capabilities.  The company felt that the reputation of quality of the PT6A series engine aligned well with the reputation of quality at Covington Aircraft.  Ron served as Chief Inspector for the Radial Division and his personal commitment to quality helped the company to launch its Turbine Division in the mid 1990’s.  Ron says that Aircraft maintenance is not for the faint-hearted; it requires a strong commitment to quality!

Ron was sent by Covington to Pratt & Whitney Canada for factory training on a variety of PT6A turboprop engine models.  Ron said. “Learning the turbine engine was a radical change for me.”  It was a change he picked up extremely quickly, and it launched him down the path he’s on today.  Aircraft engine overhaul and maintenance has always been a joy to Ron and his time working with PT6A engines has been well spent.

Now, Ron has moved to helping with Covington Aircraft’s customer base with a new role as Customer Support Representative.  “This job affords me with a wonderful opportunity to work with people around the world,” says Ron.  Switching to an office position took some adjustment, but everyone at Covington is thrilled to have Ron working in such a vital capacity for the company.

Covington has been like a dream for Ron, who obtained his Pilot’s License from Letourneau University along with his A&P Mechanics license.  Covington Aircraft has given Ron the ability to work in the aircraft engine overhaul business; which he’s grown to love and appreciate.

Ron has been with the company for almost 29 years and his experience is a valuable asset to Covington.  As a company, Covington is working to use his experience in training others within the company to make sure the valuable knowledge, skills and experience Ron has accumulated over the years are not lost!
