Event Overview
During a visual flight rules (VFR) departure, the cabin door on the right side of the airplane came open. The pilot, who was occupying the left seat at the time, decided to return to the airport for landing.
Return and Landing
The altitude that had been reached when the door opened was maintained throughout a modified traffic pattern as the pilot flew back to the airport. During the landing sequence, the airplane made hard contact with the ground, causing the right main landing gear to collapse.
Outcome
No further details were provided regarding the extent of damage or injuries. The incident remains documented as a hard landing with collapse of the right main landing gear following an in-flight door opening.
