NTSB narrative
The airplane's clamshell canopy door departed the airframe and struck the pilot's shoulder, while in a banking maneuver. As the pilot initiated a 30-degree turn to the left, the airplane's left canopy door suddenly became ajar, and he experienced difficulty flying the airplane. He attempted to regain control of the airplane, and about 2 to 3 seconds later, the door canopy separated completely from the airframe. After detaching, it struck the pilot's left shoulder, and then impacted the side of the fuselage; he landed at the airport without further incident. After egressing the cockpit, both pilots noted that the canopy latching mechanism was still in the locked position, affixed to the airframe. After several doctor's visits, the pilot was determined to have suffered tendon damage to his left shoulder. Technical examination of the airplane disclosed that the upper aft hinge of the canopy door failed first, followed by the forward hinge and a bolt attaching the bottom latch to the frame. The hinge had apparently undergone stress from the door remaining open during windy conditions or while the propeller was under power over an undetermined number of prior flights. The airplane's flight manual indicates in several locations that the door is to remain closed during such conditions.
Probable cause
an in-flight separation of the left cockpit door due to the failure of the hinges from repeated exposure to wind or propeller slip stream forces while in the open position. The hinge failures were the ultimate result of the failure of persons unknown to follow the procedures/directives in the airplane flight manual.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
