摘要

Parking an airplane for an extended period of time - like most airlines have done during the COVID-19 Pandemic - introduces uncertainty and risk, especially if the maintenance performed prior to storage and later during return to service (RTS) is not properly executed. The actions taken by each person involved in these maintenance actions are critical to ensuring the airworthiness of the airplane. A recent example of this could was evident in an FAA emergency airworthiness directive issued last July for inspections of older Boeing 737 aircraft after four engine failures occurred due to a stuck bleed air check valve from corrosion. These airplanes were all parked due to the recent pandemic prior to RTS.However, these same issues have been well-documented in other accidents and incidents long before COVID-19. Case-in-point: Dynamic Airways flight 405 on October 28, 2015.
