The maintenance requirements for Wheels and Brakes are clearly affected by flight cycles and require regular inspections to ensure continuing integrity. Maintaining an inventory of Landing Gear can incur significant expense and airlines typically avoid the cost by relying on contracted specialist providers or the original equipment manufacturer (OEM), which poses additional logistical consideration for airlines. With a full understanding of the maintenance requirements it is relatively straight forward to determine when the landing gear will require a shop visit and whether it will be driven by calendar or FC parameters.
Landing gear maintenance is generally referenced to Flight Cycles (FC) or Years in Service and consists of a range of activities including routine maintenance (mostly lubrication) repairing non-routine (NR) defects, together with shop visits (SVs) for the accomplishment of overhaul processes. Wheel and Brake Components are usually on condition and the Landing Gear itself is typically a hard-timed component. All ATA Chapter 32 components are subjected to Stress and Wear during continuous operations.Ĭhapter 32 aircraft maintenance requirements also call up activity on landing gear doors, retraction system, hydraulic control valves and components as well as steering and indication. Together they create a significant maintenance requirement throughout the duration of the operation of the aircraft.
ATA Chapter 32 includes the Landing Gears together with the Wheels and Brake Systems.
