Narrative:A Dornier 328-100 operated by South East Asian Airlines sustained substantial damage in a runway excursion accident at Manila-Ninoy Aquino International Airport, Philippines.
The aircraft departed from Caticlan Airport at about 11:45 hours, with an estimated arrival time at Ninoy Aquino International Airport of 12:35. The captain was Pilot Flying.
The aircraft conducted a visual approach to runway 13 and touched down smoothly. Subsequently, at approximately 6 seconds after touch down the aircraft started veering to the right and departed the runway surface onto a soft grassy portion at the side of the runway. The nose wheel collided with a runway light. An emergency evacuation was not required, and all of the aircrafts occupants disembarked normally through the aircrafts main door. There were no injuries reported.
Probable Cause:
PROBABLE CAUSE: "The Aircraft Accident Investigation and Inquiry Board determine that the probable cause of this incident was the uneven traction of the nose wheel tires on the ground because of the difference in height, contributed by the cross tail wind which was quite substantial at the time of the incident. (Weather vaning into the wind). Another contributory factor is the incorrect pilot technique used when the aircraft started to veer to the right by applying left rudder instead of differential braking to realign the aircraft to the runway."
Classification:
Runway excursion (veer-off)
Follow-up / safety actions
AAIIB issued 4 Safety Recommendations
