Modern aircraft is one of the most complex machines ever created. The Airbus A380 for instance is composed of over a million parts. Companies involved in the Maintenance, Repair & Operation (MRO) of aircraft engines cannot afford to keep stock of too many components as buffer, for obvious reasons. Aircrafts undergo periodical checks such as A & C checks and delay in component availability will lead the aircraft to be grounded for a longer duration than necessary.
The engine maintenance schedule involves a series of tasks such as Engine dis-assembly, inspection and cleaning, reconditioning and repair of crankcase, crankshaft, connecting rods etc. MRO companies have to adhere to stringent quality control measures regarding engine performance, efficiency, engine smoothness and protection. The fuel injection systems, cylinders, turbo chargers and valves and propellers are some important engine components that require proper servicing and overhaul. Any problem in fuel line should be replaced and not just repaired. Aircraft engine maintenance involves the safety of the passengers and crew concerned and therefore, no aspect of the maintenance schedule or component servicing can be taken lightly
