Zantop International Airlines

Lockheed L-188 Electra

Zantop ground personnel completed the loading of Flight 931 at 00:40. All cargo was bulk loaded and tied down on the right side of the airplane for the full length of the cargo compartment. Flight 931 departed the gate at Baltimore/Washington International Airport at 01:05 and took off on runway 28 at 01:10. At 01:11:42, Flight 931 contacted Baltimore departure control and was cleared to 13,000 feet. After switching to Washington ARTCC, the flight was cleared further FL220. At 01:32 a no. 2 gyro malfunction made the crew select the no. 1 gyro to drive both approach horizons and the problem appeared resolved. At 01:43:09, Cleveland ARTCC cleared Flight 931 direct to the Dryer VOR. After the turn to the Dryer VOR, the first officer’s approach horizon may have displayed incorrect pitch and roll information. The flightcrew may have received conflicting pitch and roll information from the two approach horizons as they attempted to recover from an unusual attitude. The flightcrew overstressed the airplane in an attempt to recover from the unusual attitude as the aircraft spiralled down. The Electra broke up and falling wreckage damaged some houses; however, most of the wreckage fell in uninhabited, wooded areas.

On approach to Deadhorse Airport, the crew encountered poor weather conditions when the airplane struck the runway surface 1,000 feet past its threshold. After initial impact, the left wing was torn off and the airplane went out of control. On a snow and ice covered runway, the airplane veered off runway to the left before coming to rest in flames few hundred yards further. All three crew members escaped uninjured while the aircraft was destroyed.

Just after liftoff from runway 03R at Detroit-Wayne County Airport, while in initial climb, the airplane crashed on a fuel storage tank and exploded. Both pilots, en route to Lexington on a ferry flight, were killed, as well as one people on the ground.
