Incident Overview

Description
Air Inuit flight 820, a DHC-8-314, suffered a tail strike on landing at Schefferville Airport, Canada. The aircraft had departed Montral-Pierre Elliott Trudeau Airport (CYUL) at 07:06 hours local time on a multi-stop flight to Salluit. The accident occurred on the second leg, from Montral to Schefferville. Findings as to causes and contributing factors: 1. The pilots forgot to perform the descent checklist and realized this at an inopportune time, when the pilot monitoring was providing a position report. 2. Given the ambiguities and contradictions in the stabilized approach guidelines, the captain interpreted that he was allowed to continue the approach below 500 feet above aerodrome elevation although the flaps had not been set to 35ø and the final checklist had not been completed. 3. Communicating with the flight attendant to confirm the cabin status and performing the descent checklist during final approach added to the pilots workload, which was already heavy. 4. The combination of the visual conditions and the plan continuation bias prompted the pilots to continue managing the height and speed deviations past the stabilized approach gate. 5. When the aircraft passed 500 feet above aerodrome elevation, the pilots, who were dealing with a heavy workload, passed the stabilized approach gate without noticing it and continued the approach, which was de facto unstable. 6. At the time of the flare, the aircraft no longer had enough energy to stop the rate of descent solely by increasing the pitch attitude. 7. The instinctive reaction to increase the pitch attitude, combined with the hard landing, resulted in the aft fuselage striking the runway, causing major damage to the aircrafts structure.
Primary Cause
Pilot error ? failure to perform the descent checklist and misinterpretation of stabilized approach guidelines, leading to an uncontrolled descent and subsequent tail strike.Pilot error ? failure to perform the descent checklist and misinterpretation of stabilized approach guidelines, leading to an uncontrolled descent and subsequent tail strike.Share on:
