With dampened demand for air travel caused by the COVID-19 Pandemic, many airlines resorted to grounding and storing their fleet of aircraft including one of the most famous aircraft types with Boeing having delivered over 10,000 Boeing 737 single-aisle jets.

The US Federal Aviation Administration (FAA) had issued an emergency safety directive to airlines to check for any kind of corrosion on the engine valves of their stored B737 fleet, the FAA directive orders inspection on the aircraft that haven’t flown for over 6 days. This would impact around 2,000 jets within the US, the directive was put into effect after 4 incidents had occurred on the aircraft type and are not linked to the B737 Max groundings.
