Incident Summary
A pilot reported that upon arrival at the intended destination, the landing gear would not extend. He subsequently returned to Opa Locka Airport, where he executed an intentional gear-up landing.
Investigation Findings
Post-crash examination of the aircraft revealed that the landing gear system was unable to operate normally. The down limit micro switch was stuck in the open position, which prevented electrical power from reaching the gear motor to move the gear to the down position. Additionally, the emergency manual crank system was inoperative because the drive chain was disconnected.
Technical Details
The investigation determined that the gear could not be lowered through normal electrical means due to the micro switch malfunction. The disconnected drive chain also rendered the manual emergency extension system ineffective, leaving the pilot with no alternative means to deploy the landing gear.
