The IAI 1124A Westwind crashed following an aborted takeoff from runway 24 and burst into flames at Manila-Ninoy Aquino International Airport, Philippines. The aircraft carried out a medical evacuation flight to Tokyo, Japan. Signs of heavy braking were found on the runway. After exiting from the asphalted portion of runway safety area, the aircraft initially run over two runway edge lights then impacted into a concrete electric junction box and came to a complete stop at the runway secondary fence. PROBABLE CAUSE – Primary Cause Factor a. The decision of the PF to abort the take-off after VR that resulted to runway excursion. b. Incorrect pilot techniques or procedures in the high-speed rejected take-off. – Contributory Cause Factors: a. Operational pressures related to the delay of schedule due to late filing of the flight plan compelling the crew to rush and meet the schedule demand. b. The crew’s complacency by skipping required briefing item in the before take-off checklist, in this case, the considerations in the event of a malfunction before/after V1.
