What happened
During the approach into the airport, the pilot encountered an issue where the flaps would not lock into the 20-degree extended position. In response to this difficulty, the pilot decided to perform a no-flap landing and consulted the emergency checklist. While reviewing the procedures, the pilot focused on maintaining a stabilized approach and inadvertently overlooked the instruction to extend the landing gear, under the mistaken impression that the gear was already down and locked.
As a result, the aircraft touched down on the runway with the landing gear in the retracted position. There were no injuries reported following the incident.
The investigation
An examination of the landing gear system revealed no mechanical malfunctions. Additionally, a ground test run of the flaps was conducted, but the failure encountered during the flight could not be reproduced.
