US-Bangla plane crash probe: no reason identified yet

Dhaka – The preliminary probe report submitted by the Nepalese investigators could not determine as to what caused the last month’s deadly crash of a US-Bangla flight at Tribhuvan International Airport.

But the probe report, made public on Thursday, said that there was no corresponding replies or acknowledgements between the pilot and the Air Traffic Control at the airport before the crash.

The crash left 51 people, including 27 Bangladeshi nationals, dead on March 12.

The five-page report noted all important equipment including the “Black Box” of the crashed aircraft sent to Transport Safety Board (TSB) of Canada for downloading, decoding, readout and analysis including animation to prepare a final report on the accident.

“Two-way communication between the aircraft and the approach as well as tower control was normal until 14:17:58 (local time),” said the report.

A few transmissions were made by both ATC and the Pilot until 14:18:45, but no corresponding replies or acknowledgements were made from either side, the report added.

The crash happened at 14:19:10 in the eastern part of the field of Runway 02, just outside the inner perimeter fence of the aerodrome of the airport, affirmed the report.

The Nepalese authorities formed the investigation committee as Aircraft Accident Investigation Commission 2018 to determine the cause of the accident. The commission published the report on April 9 and sent to Civil Aviation authority of Bangladesh on Wednesday.

“The aircraft touched down at about 1700 meters down the threshold and on the left portion of centerline of Runway 20 and travelled on ground towards Southeast, went out of the Runway, ran through the inner perimeter fence of the airport area, moved down along rough downslope and finally stopped at about 442 meters Southeast side of the Runway from its initial touchdown point,” the report mentioned.

“At this point, the aircraft caught fire and was completely destroyed,” it continued.

The runway, taxiway and apron area at Tribhuvan International Airport were adequate for the operation of the DHC-8 Q 400 aircraft, the model of US-Bangla crashed plane, according to the probe report.

The fire-fighting and emergency services reached the crash site within two minutes and immediately launched operation to douse the flames.

Four large foam tenders, one medium foam tender and two water tankers were used with full effectiveness, the report said adding that the process of investigation is ongoing and the Commission would make the final report publicly available as per the provisions outlined in Chapter 6, Section 6.5 of ICAO Annex 13.

 

The reviewing of the available documents and testing, decoding, research and analysis of all pertinent equipment retrieved from the aircraft are ongoing and the results shall be included in final report, it added.

Apart from Nepalese officials, the investigation commission included representatives from the host country, aircraft manufacturer – Bombardier of Canada, and engine manufacturer of the aircraft, a British company.

Capt Salahuddin M Rahmatullah of Bangladesh’s Aircraft Accident Investigation Group has been representing Bangladesh in the panel.
