Final answer:
If an aircraft has not flown in 30 days, a determination must be made of when the aircraft is expected to be flown. If the aircraft is expected to exceed 30 days of non-flight, the aircraft must be preserved per the most appropriate level specified in NAVAIR 15-01-500.
Step-by-step explanation:
When an aircraft has not flown for 30 days, it triggers the need for a determination of when it is expected to be flown again. This assessment helps determine the appropriate preservation actions.
The determination involves estimating the duration of non-flight for the aircraft. If the expected non-flight period is less than or equal to 30 days, additional preservation actions may not be necessary.
The choice of preservation level depends on the circumstances and requirements. NAVAIR 15-01-500 specifies different levels of aircraft preservation, ranging from short-term to long-term, depending on factors such as the expected duration of non-flight and the preservation requirements for different aircraft systems.
