Zest A320 at Kalibo on Dec 30th 2014, runway excursion
Last Update: September 18, 2015 / 14:50:01 GMT/Zulu time
No weather data are available for Kalibo, the Philippines however are under the influence of Tropical Storm Jangmi. A passenger waiting for departure from Kalibo tweeted "Weather is crazy". A local resident of Kalibo reported it was raining hard starting in the night. Weather Services in the Philippines advised in the morning that operation at Kalibo Airport would remain normal.
Kalibo features a LOC and VOR approach to runway 23, no instrument approach is published for runway 05.
The Civil Aviation Authority of the Philippines (CAAP) released the summary of their final report concluding the probable causes were:
The Aircraft Accident Investigation and Inquiry Board determined that the probable cause of this accident was:
Primary Cause Factor
Failure of the PIC to discontinue the approach despite poor weather condition that suggest a Missed Approach should have been initiated.(Human Factor)
The Pilot-In-Command clearly disregarded the normal and standard basic operating procedures setforth in the operations manual. This is a clear manifestation of poor judgement on the part of the PIC which violates the basic rules of the air and apparently endangers flight safety.
- The unfavorable tailwind condition which was more than 10 knots.
- Kalibo International Airport has one way traffic pattern to land during night operation since Runway 05 has no Instrument Landing System (ILS).
The CAAP reported in their executive summary, that the aircraft was on approach to Kalibo's runway 23 with winds reported from 030 degrees at 16 knots, the tower cautioned of tail wind and wet runway. The captain disconnected the autopilot and flew the aircraft manually and landed. The aircraft continued the roll out, veered slightly to the right just prior to the runway end, overran the end of the runway and came to a stop 66 meters past the runway end on the grassy area of the runway end safety area. Emergency slides L2 and R2 were deployed, the passengers disembarked without injuries.
The CAAP, apart from recommending strict adherence with procedures in particular go around and stabilized approach critera/procedures to Zest, also recommended the installation of an ILS system for Kalibo's runway 05.
