Aircraft maintenance is the performance of tasks required to ensure the continuing airworthiness of an aircraft or aircraft part, including overhaul, inspection, replacement, defect rectification, and the embodiment of modifications, compliance with airworthiness directives and repair.
The aircraft manufacturer makes sure that the aircraft meets existing design standards, defines the operating limitations and maintenance schedules and provides support and maintenance throughout the operational life of the aircraft. The aviation operators include the passenger and cargo airliners, air forces and owners of private aircraft ...
The term "reliability-centered maintenance" authored by Tom Matteson, Stanley Nowlan and Howard Heap of United Airlines (UAL) to describe a process used to determine the optimum maintenance requirements for aircraft [3] [disputed – discuss] (having left United Airlines to pursue a consulting career a few months before the publication of the final Nowlan-Heap report, Matteson received no ...
For a complex engineering system containing thousands of assemblies, sub-assemblies, components, organized into several levels of indenture and with a number of possible repair decisions, LORA seeks to determine an optimal provision of repair and maintenance facilities to minimize overall system life-cycle costs.
The concept of Smart Intelligent Aircraft Structures offers significant improvements in aircraft total weight, manufacturing cost and, above all, operational cost by an integration of system tasks into the load carrying structure. [2] It also helps to improve the aircraft's life cycle and reduce its maintenance. [3]
Aircraft maintenance checks are periodic inspections that have to be done on all commercial and civil aircraft after a certain amount of time or usage. Military aircraft normally follow specific maintenance programmes which may, or may not, be similar to those of commercial and civil operators.
The general flow of the safety life cycle under ARP4761 is: Perform the aircraft level FHA in parallel with development of aircraft level requirements. Perform the system level FHA in parallel with allocation of aircraft functions to system functions, and initiate the CCA.
Understanding the "as is" state of an asset and its major components is an essential element in preventive maintenance as used in maintenance, repair, and overhaul and enterprise asset management systems. Complex assets such as aircraft, ships, industrial machinery etc. depend on many different components being serviceable.
