The US aviation authority and Boeing are unlikely to become good friends anymore. Because now the FAA is determining that older 737s that have not been flown for more than a week need a special inspection. The reason for this is a valve in the engine, which can start to rust after a short time. In the worst case, this could lead to engine failure.

In the course of the Corona compulsory break and the shutdown of several aircraft, around 2000 machines of this series are affected, how handelsblatt.com reported. The US aircraft manufacturer has already informed the airlines about this and advised them to check the valves again as a precaution. If necessary, you can also count on the Airbus rival when replacing the parts.
