Aircraft Accident/Incident Report
San Juan
Sunday, March 12, 1995 13:05 AST
NTSB Narrative Summary Released at Completion of Accident
The tug operator was cleared by the dispatching agent to commence pushback procedures at a departure gate on a Delta L- 1011. The lead wing walker observed an American SD3-60 taxiing to the ramp and signaled the tug operator to terminate the pushback, which was complied with. The tug operator observed the SD3-60 taxi past the L-1011, and commenced pushback procedures without clearance from the dispatching agent. The right wing tip of the L-1011 collided with the rudder of the SD3-60. Delta Airlines SOP states, the tug operator is responsible for following the signals of the dispatching agent.
NTSB Probable Cause Narrative
THE FAILURE OF THE TUG OPERATOR TO FOLLOW CORRECT PUSHBACK PROCEDURES BY COMMENCING PUSHBACK WITHOUT CLEARANCE, RESULTING IN AN ON-GROUND COLLISION WITH ANOTHER AIRPLANE.
