The Nigerian government released the investigation report on the possible causes of the Dana airline crash by the Accident Investigation Bureau (AIB).

According to the preliminary official report,dual engine failure caused the crash of a Nigerian plane that killed 150 people on board,including two Indians,last month.

An Indian from Kerala,Rijo Eldos,was traveling in the aircraft which crashed into a building in a highly populated area of Nigeria\’s commercial capital

The Chief Executive Officer and Commissioner of AIB,Captain Muhtar Usman,said the plane crashed,because of complete loss of power from its two engines while approaching the Murtala Muhammed Airport in Lagos.

The preliminary report stated that the plane was on the fourth flight segment of the day,and had made consistent two round-trips between the commercial city of Lagos and the country\’s capital Abuja.

Reportedly the accident occurred during the return leg of the second “DAN 992 was on final approach for runway 18R at Lagos when the crew reported the total loss of power”.

The plane after taxing in Abuja was airborne after initial confirmation by the ground engineers that it had a fuel endurance of 3.5 hours.

The cockpit voice recorder (CVR),retained about 31 minutes of the flight. At 03:15 pm,the captain and first officer were in a discussion of a non-normal condition regarding the correlation between the engine throttle setting and an engine power indication.

According to the statement,the flight crew did not voice concerns then that the condition would affect the continuation of the flight as they continued to monitor the condition.

They became increasingly concerned during the flight transition through the initial descent from cruise altitude at 03:22 pm and the subsequent approach phase. It was at the crucial decision moment,between the period of 03:37 pm and 03:41 pm,that the flight crew engaged in pre-landing tasks including deployment of the slats,and extension of the flaps and landing gear.

“At 03:41 pm the first officer (FO) inquired,\’Both engines coming up?\’ and the captain (Capt) replied “negative”. The flight crew subsequently discussed and agreed to declare an emergency. At 03:42 pm,DANA 992 radioed an emergency distress call indicating “dual engine failure… negative response from throttle”.
