Why Is Plane Maintenance So Important?

There is no denying that plane maintenance is one of the most critical aspects of plane ownership.  In fact, the FAA places so much importance on plane safety that they require a thorough aviation maintenance and inspection process for every 100 hours that a plane is used for hire.  For this reason, aircraft technicians must be highly skilled and demonstrate a keen attention to detail when it comes to aircraft maintenance.

Routine Maintenance

plane maintenanceUnder FAA oversight, plane owners and operators create Continuous Airworthiness Maintenance Programs (CAMP) that detail both routine and detailed inspections for each aircraft.  Authorities often refer to these inspections as checks.  A and B checks are usually considered more routine maintenance inspections, while C and D checks are more detailed inspections.  An A check is often performed overnight at an airport gate every 500-800 flight hours and a B Check is normally done every 3 to 6 months at an airport hangar.  During this plane maintenance, routine maintenance and checks are performed.  During a C check, which is done every 15 to 21 months, almost the entire aircraft is checked.  This means that the aircraft is out of service until the maintenance is performed, a process that can take up to 2 weeks to complete.  D checks are the most comprehensive inspections and are performed every 5 to 6 years.  Because of the detail of this plane maintenance, the inspection can take up to 2 months.

Passenger Safety

One of the most important reasons for performing extensive plane maintenance is to protect any passengers that may be using the aircraft.  Regularly scheduled plane maintenance and inspections ensure that passengers will have a safe, pleasant transportation experience and that they will arrive at their destination in a timely manner.

Need Grows for Aviation Maintenance Technicians

As air travel continues to increase, plane maintenance becomes especially important.  Annual inspections, routine maintenance and repairs can create a tremendous burden on an aircraft owner and creates a growing need for qualified, licensed aviation maintenance technicians.  These technicians are highly skilled and have a keen attention to detail that is necessary to keep an aircraft flying.

Air travel will continue to be an important way for people and cargo to get from one destination to another in the quickest fashion.  For this reason, plane maintenance will continue to be a crucial factor in the aircraft industry.  If you need maintenance on your aircraft, reach out to Covington Aircraft.  We maintain, overhaul, and sell turbine and radial engines.  Call us at (918) 932-3993.

The Terminology and Standards of Aircraft Engine Overhaul – Part 1

This is the first post of two in our efforts to educate aviation enthusiasts, aircraft owners, and business fleet aircraft managers on the terminology of an aircraft engine overhaul.  If you are in need of maintenance or overhaul for your radial or turbine engine, make sure you visit Covington Aircraft’s website for more information!

When TBO time rolls around, are you ready to speak and understand the language enough to make an informed decision?

Air-Tractor-Landing-at-Hangar-1024x676Parents everywhere tell their children, “Read everything before you sign it.”  What good is this advice if you have no understanding of what you are reading?  Sure, many things are intuitive, but a clear understanding of what is offered for services further ensures that you will get value for your dollar.  The following is a listing and discussion of what various terms mean when it comes to aircraft engine overhaul. You may not know how to check the free-play on a valve tappet after reading this, but at least you should know your O.E.M from aftermarket enough to discuss your options.

Terms that are used and approved by the FAA.

NEW ENGINE:

A new engine is one that has been manufactured from all new parts and tested by an FAA-approved manufacturer.  The engine will have no operating history except for test cell time when received.  No FAA-approved manufacturer can approve another entity to manufacture or assemble a NEW ENGINE.

NEW LIMITS:

These are the FAA-approved fits and clearances manufacturers adhere to with new engine.  This may be accomplished using standard or approved undersized and oversized dimensioned parts.

SERVICE LIMITS:

The service limits are the FAA-approved allowable wear fits and tolerances to which a new limit part may deteriorate and still be a useable component.  This may also be accomplished using standard and approved undersized and oversized dimensions.

OVERHAULED ENGINE:

REBUILT ENGINE:

This is an engine that has been overhauled using new and used parts to new limits by the manufacturer or an entity approved by the manufacturer.  The engine’s previous operating history is eradicated, even though the engine may have used components installed that have many hours of operating history, and it comes to you with zero hours total time in service

O.E.M. and AFTERMARKET:

When an engine is overhauled or rebuilt, the new parts that are used during the repair process can come from a variety of sources.  An “O.E.M.” part is a new part that is manufactured by the original engine manufacturer to stringent FAA standards.  An “aftermarket” part is a new part that is manufactured by someone other than the original engine manufacturer and meets or exceeds the same stringent FAA guidelines as a new O.E.M. part.

So, now you know enough to be dangerous! However, put your aircraft engine overhaul into the hands of the experts who have performed thousands upon thousands, either at the Hangar in Okmulgee, OK or wherever you are located, and give Covington Aircraft a call today!  Next week we will go over some other aircraft maintenance terminology. Happy Flying!
