Narrative:
Xiamen Airlines flight 8667, suffered a runway excursion after landing on runway 24 at Manila-Ninoy Aquino International Airport, Philippines. There were no injuries according to the airline.
At 23:08 hours local time the flight had descended to FL180 towards Manila. It entered a holding pattern to the north-east of the airport for about 14 minutes before positioning for an approach to runway 24. The approach was aborted at 23:40 and the aircraft position for another approach. The aircraft touched down at 23:55 but went off the runway.
At the time of the accident a thunderstorm was passing the airport.

Photos from the scene seem to indicate that the no.1 (left hand) engine had separated from the wing after the excursion.

Primary Cause Factors
a. The decision of the Captain to continue the landing on un-stabilized approach and insufficient visual reference.
- The Captain failed to maintain a stabilized landing approach moments before touchdown, the aircraft was rolling left and continuously drifting left of the runway centerline.
- The Captain failed to identify correctly the aircraft position and status due to insufficient visual reference caused by precipitation.
b. The Captain failed to apply sound CRM practices.
- The Captain did not heed to the First Officer call for a Go-Around.
Contributory Factors
a. Failure to apply appropriate TEM strategies
Failure of the Flight Crew to discuss and apply appropriate Threat and Error Management (TEM) strategies for the following:
- Inclement weather.
- Cross wind conditions during approach to land.
- Possibility of low-level wind shear.
- NOTAM information on unserviceable runway lights.
b. Inadequate Company Policy on Go-Around
- Company’s Standard Operation Procedures were less than adequate in terms of providing guidance to the flight crew for call out of "Go-Around" during landing phase of the flight.
c. Runway strip inconsistent with CAAP MOS for Aerodrome and ICAO Annex 14
- The uneven surface and concrete obstacles contributed to the damage sustained by the aircraft
