Airport (less than 10 km from airport)

The jammed condition of both elevators, which resulted from exposure to localized, dynamic high wind while the airplane was parked and prevented the airplane from rotating during the takeoff roll. Also causal was the failure of Everts Air Cargo, the pilots’ primary employer, to maintain awareness of Boeing-issued, required updates for its manuals, which resulted in the pilots not receiving the procedures and training that addressed the requirement to visually verify during the preflight checks that the elevators are not jammed.

The pilot’s inability to control the airplane’s pitch during departure for reasons that could not be determined because of the extensive fragmentation and thermal damage the airplane sustained in the accident sequence.

Findings as to causes and contributing factors:
1. The aircraft joined the final approach well above the optimal 3° descent path and, during the steep approach that followed, the aircraft’s airspeed continually decelerated and resulted in an unstabilized approach.
2. On short final, the pilot reduced the rate of descent by increasing pitch rather than by adding power. As a result, the airspeed continued to decrease and the aircraft entered a stall, resulting in a hard landing and a subsequent bounce.
3. During the attempted rejected landing, the aircraft entered a 25° nose-high attitude and approached a stall condition. This low-speed condition combined with the high power setting resulted in the aircraft entering a rapid roll to the left and striking the runway in an inverted attitude.
4. The passengers did not receive a safety briefing before departure or before landing, and multiple items in the cabin were not secured. As a result, 1 passenger sustained serious injuries due to the deceleration forces and the loose items that were thrown around in the cabin during the accident.
5. The pilot was not wearing the available shoulder harness, and his torso was unrestrained during the impact. As a result, he sustained serious injuries.

Findings as to risk:
1. If pilots do not declare all health issues to Transport Canada Civil Aviation Medical Examiners and pilots’ family physicians do not declare issues assessed to be a risk to aviation safety to Transport Canada, there is an increased risk that pilots will operate with diagnosed medical conditions or medical side effects that could affect flight safety.
2. If an aircraft propeller is rotating and passengers are not supervised during boarding operations, there is a risk that passengers may inadvertently contact the propeller, potentially causing fatal injuries.

Other findings:
1. Following a review of the pilot’s medical history and prescription medication use, the investigation determined that the medication did not contribute to the accident.
