Selection of Zones for Degradation Testing
Maintenance zones within an aircraft are not homogeneous. They vary from the extreme Aircraft areas within the aircraft (engines) to more benign areas (inside pressure and temperature-controlled areas). And because of this, the components within each of these zones will age at different rates. Naturally, different components are selected for each of these zones; those components better able to handle the severe environments are installed in those environments, and lower requirements are placed on those parts installed in benign environments.
