Germany has set a series of rules to be implemented in order to have its NH90 fleet resume flight operations.
Flight restrictions were put in place earlier after Airbus traced the cause of an engine fire in a German NH90 that was flying over Termez, Uzbekistan in June last year. The company discovered a design fault in the aircraft’s overhead control panel. The fault had triggered the fire extinguishing system in one of the engines.
Before each flight, pilots are required to vent the engines before every start up.
