What happened
The aircraft was involved in an instructional flight intended for a biennial flight review. The pilot reported that during the landing phase, direct sunlight impaired visibility. On final approach, the aircraft encountered a downdraft which led to contact with a three-foot snowbank situated on the end of the runway between the threshold lights.
The investigation
The investigation focused on the circumstances surrounding the impact. The primary finding was the physical damage sustained from striking the snowbank at the runway's end. No mechanical failures were reported prior to the event.
Findings
Contributing factors included the pilot's inability to see due to sun glare and the presence of a downdraft during the final approach. The Cessna 172 sustained damage from the impact with the snowbank. The pilot was not injured, but the flight instructor was also present on board. The accident occurred during the landing phase.
Safety message
Pilots should be aware of the potential for sun glare to impair vision during critical phases of flight, particularly when approaching runways with obstacles or uneven terrain at the ends.
