Aviation investigation A11H0002 First Air accident, Resolute Bay, Nunavut, 20 August 2011


First Air accident, Resolute Bay, Nunavut, 20 August 2011
The occurrence


On August 20, 2011, First Air Boeing 737-210C combi aircraft was being flown from Yellowknife, NWT to Resolute Bay, NU. During the approach to runway 35T, the aircraft struck a hill about 1 nautical mile east of the midpoint of the Resolute Bay airport runway. There were 4 crewmembers and 11 passengers on board the aircraft. The crewmembers and eight passengers were fatally injured. Three passengers survived the accident and were recovered from the site by Canadian military personnel who were in Resolute Bay for Exercise Operation Nanook. The aircraft was destroyed and there was a post-impact fire.
Data recorders


The aircraft was equipped with two data recorders, a Flight Data Recorder (FDR) and a Cockpit Voice Recorder (CVR).


The FDR records parameters such as airspeed, altitude, heading, engine power settings, flight control movement and positions and instrument settings. These parameters help investigators understand how the aircraft was performing in the final minutes of flight.


The CVR records the conversations between the pilots and Air Traffic Control, as well as between the pilots. There is also a cockpit area microphone that records sounds heard in the cockpit as well as any audible warning systems.


Data recorders are vital to helping investigators understand what the aircraft and crew were doing in the final moments of a flight.

Transportation Safety Board investigation process


There are 3 phases to a TSB investigation:
Field phase: a team of investigators examines the occurrence site and wreckage, interviews witnesses and collects pertinent information.
Examination and analysis phase: the TSB reviews pertinent records, tests components of the wreckage in the lab, determines the sequence of events and identifies safety deficiencies. When safety deficiencies are suspected or confirmed, the TSB advises the appropriate authority without waiting until publication of the final report.
Report phase: a confidential draft report is approved by the Board and sent to persons and corporations who are directly concerned by the report. They then have the opportunity to dispute or correct information they believe to be incorrect. The Board considers all representations before approving the final report, which is subsequently released to the public.
