On August 20, 2007, at 0929 UTC, a U. S. registered Boeing 767-323, N369AA, operated by American Airlines as American Flight 84, sustained smoke in the airplane's cabin while taxiing to parking at the Frankfurt Am Main Airport (FRA), Frankfurt, Hesse, Germany. Day visual meteorological conditions prevailed at the time of the incident. The scheduled international passenger flight from Chicago, Illinois, to Frankfurt, Germany was operating on an instrument flight rules flight plan under the provisions of Title 14 Code of Federal Regulation Part 121. The pilot, copilot, 10 flight attendants and 158 passengers on board were not injured.

According to the company, while en route, the flight crew received overheat status messages accompanied by popped circuit breakers. The flight crew followed proper procedures. When on the ground at FRA, while taxiing to the gate, the crew started the airplane's auxiliary power unit. Shortly after starting the APU smoke began to appear in the cabin. The flight crew proceeded immediately to the gate and expedited getting the passengers off the airplane.

Investigators for the German Bundesstelle fur Flugenfallensuchung (BFU) discovered "ruptured" wires adjacent to a wire clamp in the airplane's aft cargo compartment. The sheathing around the wire bundles, the adjacent cargo compartment bulkhead walls and compartment insulated padding were charred and partially consumed.

This investigation is under the jurisdiction and control of the German government. Any further information may be obtained from:
