Incident Overview
On a routine flight from El Nido Palawan, a DHC-6 Twin Otter landed at Manila-Ninoy Aquino Airport. The crew was instructed by air traffic control to taxi via taxiway F1 to reach their parking position. Concurrently, a Boeing 737-3Y0 operated by Philippine Airlines, operating as flight PR1370 from Manila to Bacolod, was commencing its takeoff roll on runway 13.
Sequence of Events
While taxiing, the Twin Otter crew received an instruction to hold on taxiway F1. For reasons not determined, the crew misinterpreted this instruction and proceeded to cross the active runway. As the Twin Otter entered the runway, the Boeing 737, already in its takeoff roll, collided with the smaller aircraft. The impact dragged the Twin Otter for approximately 130 meters before coming to a stop.
Damage and Injuries
The Boeing 737 sustained slight damage to its nose section. The Twin Otter was destroyed in the collision. Both pilots of the Twin Otter were injured. The extent of injuries was not specified in the source.
Probable Cause
The official investigation determined the probable cause to be: "Failure of the crew to follow ATC instruction, starting to cross the runway in use while a Boeing 737 was taking off at the same time."
