At 0939 e.s.t., November 3, 1973, Pan American World Airways, Inc., Boeing 707-321C (N458PA) crashed at Logan International Airport, Boston, Massachusetts. The airplane was destroyed, and its three crewmembers were killed. The National Transportation Safety Board determines that the probable cause of the accident was the presence of smoke in the cockpit which was continuously generated, and uncontrollable. The smoke led to an emergency situation that culminated in loss of control of the aircraft during final approach, when the crew in uncoordinated action deactivated the yaw damper in conjunction with incompatible positioning of flight spoilers and wing flaps. The Safety Board believes that the spontaneous chemical reaction between leaking nitric acid, improperly packaged and stowed, and the improper sawdust packing surrounding the acid's package initiated the accident sequence.
