What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On a passenger carrying revenue flight, the flight crew started the number 2 engine with the engine inlet and exhaust plugs installed. The engine itt rose to 550 degrees and the engine nacelle overheat light illuminated before the start was aborted. A later examination by maintenance revealed no damage to the engine. The flight crew could not see the engine inlets from the flight deck and assumed that the ground crew would remove the plugs before giving them the signal to start either engine.
