On the ground the engine ran fine. Inspection noted the clogged drain on the PS4 line. The ECU and related burner pressure lines were replaced and the plane was flown home with the crews and mechanics on board.
So a very simple failure resulted in the flight having to make the diversion.
Was another aircraft flown in to take the pax or were they kept on the original aircraft?
