A Cessna 172M operated by Publicité Aero-Gramme Inc., departed from the Saint-Mathieu de Laprairie aerodrome (CML8), QC to conduct a banner towing flight in the Montreal area with 2 people on board.
While the aircraft was flying over the St. Lawrence River near the Concorde Bridge, a loss of engine power occurred. While the pilot was attempting to conduct an emergency landing on Pierre-Dupuy Avenue, in the borough of Ville-Marie, Montréal, the left wing grazed some treetops. The aircraft began to cartwheel and struck the ground. There was a post-impact fire. The pilot was seriously injured but managed to evacuate the aircraft. The passenger was unable to evacuate the aircraft and received fatal injuries. The aircraft was destroyed. No signal was detected from the emergency locator transmitter.
Findings as to causes and contributing factors
1. During flight planning, weather forecasts indicated unfavourable conditions, making it difficult to meet the minimum requirements for a visual flight rules flight; however, the pilot decided to take off and proceed with the flight at an altitude of 500 feet above sea level, likely under the influence of an unconscious cognitive bias and the time constraints to complete the flight.
2. Atmospheric conditions conducive to carburetor icing most likely caused ice to develop, which would have reduced the engine’s ability to produce enough power to maintain the aircraft’s altitude.
3. Given the amount of ice that was quite likely in the carburetor when the carburetor heat was turned on, the melted ice entered the engine in the form of water, causing an additional loss of power.
4. To remain within visual flight rules conditions, the pilot continued the flight at an altitude of 500 feet above sea level, flying over built-up areas. Consequently, when the engine lost power, the possible locations for a safe landing were considerably limited.
5. After the loss of engine power at low altitude, the aircraft turned left to attempt to land on Pierre-Dupuy Avenue. While the aircraft was in the turn, the left wing grazed treetops, the aircraft began to cartwheel, and it struck the ground. There was a post-impact fire, and the aircraft was destroyed.
6. The passenger, who was not considered essential to the flight, was not wearing the shoulder harness at the time of impact, and received fatal injuries upon impact or during the fire that broke out after impact.
