Unfallbericht:
American Airlines flight 1400, a DC-9-82, N454AA, experienced an in-flight engine fire during departure climb from Lambert-St. Louis International Airport (STL). During the return to STL, the nose landing gear failed to extend, and the flight crew executed a go-around, during which the crew extended the nose gear using the emergency procedure. The flight crew conducted an emergency landing, and the 2 flight crewmembers, 3 flight attendants, and 138 passengers deplaned on the runway. No occupant injuries were reported, but the airplane sustained substantial damage due to the fire.

Probable Cause:

PROBABLE CAUSE: "The National Transportation Safety Board determines that the probable cause of this accident was American Airlines’ maintenance personnel’s use of an inappropriate manual engine start procedure, which led to the uncommanded opening of the left engine air turbine starter valve, and a subsequent left engine fire, which was prolonged by the flight crew’s interruption of an emergency checklist to perform nonessential tasks. Contributing to the accident were deficiencies in American Airlines’ Continuing Analysis and Surveillance System program."
