Executive Summary:At 0952 local time, on November 21, 1.980, Cont.inental Airiines/Air Micronesia, Inc., Flight 614, a Boeing 727-92C, N18479, crashed while attempting to land on runway 7 at Yap Airport, Yap, Western Caroline Islands. The aircraft touched down 13 feet short of the runway and the right main landing gear immediately separated from the aircraft. The aircraft gradually veered off the runway and came to rest in the jungle about 1,700 feet beyond the initial touchdown. Fire erupted along the right side of the aircraft as it came to a stop. All 73 occupants (67 pasiengers and 6 crewmembers) escaped before fire destroyed the aircraft. Three persons received serious injuries; the remainder received minor or no injuries.

The National Transportation Safety Board determines that the probable cause of this accident was the captain's premature reduction of thrust in combination with flying a shallow approach slope angle to an improper touchdown aim point. These actions resulted in a high rate of descent and a touchdown on upward sloping terrain short of the runway threshold, which generated loads that exceeded the design strength and failed the right landing gear. Contributing to the accident were the captain's lack of recent experience in the B-727 aircraft and a transfer of his DC-10 aircraft landing habits and techniques to the operation of the B-727 aircraft.
