Three Things to Know Before You Overhaul


There's a strong tendency to compare aviation to the automotive industry. But, the list of similarities is short. Aircraft and automobiles couldn’t be any more different. For example, if a car engine breaks down in the middle of your commute, you can just pull over and call a tow truck or try to fix it yourself, but you can’t do that when an airplane’s engine fails. 

Aviation is all about safety, so it stands to reason that preventing aircraft engine failure is a multi-step process with many different checkpoints. The pilot performs a quick preflight inspection before every flight; the maintenance crew forms A, B, C, and D checks at specified intervals; all Aircraft Engine Parts and assemblies on the aircraft have set maintenance and repair inspection schedules; and after a certain number of manufacturer-specified flight hours, there’s the overhaul. It can be a frustrating process, so here are three things everyone should know about the engine overhaul.

The overhaul is a thorough inspection of the aircraft engine— the engine assembly is removed, disassembled, cleaned, inspected, repaired as necessary, tested according to OEM guidelines, reassembled, and reinstalled. It’s a very important process in maintaining the life of the engine and the aircraft as a whole. But there are actually two types of overhaul: top overhaul and major overhaul. The top overhaul is where the whole engine is not completely disassembled, only the parts outside of the base crankcase, such as all the cylinders and pistons. The major overhaul is when the entire engine assembly is disassembled and inspected.

It’s important that you only trust your aircraft engine overhaul with overhaul professionals. The whole point of an engine overhaul is to ensure airworthiness, that the aircraft is safe to fly. If the overhaul is done incorrectly or haphazardly, the risk of danger increases. Also, overhaul professionals are better connected to OEMs and aftermarket suppliers than the average smaller and unknown option, so they can not only conduct the overhaul properly, but they can probably do so more quickly and efficiently, ultimately saving you time and money. Overhauls are expensive as is, but utilizing a non-expert that does the overhaul incorrectly just means you either have to do redo it or you risk the loss of lives and property.

Another important thing to remember is to adhere to TBOs (time between overhauls). The TBO is the number of running or flight hours the aircraft engine’s OEM recommends between overhauls. Aircraft can’t be repaired on the side of the road when they break down the way a car does, so it’s best to stick to a strict TBO schedule and make sure that everything is taken care of before it becomes a problem. While the overhaul is a lengthy and expensive process, it’s worth it to know that you’re flying safe and sound.
