Incident Overview
During a flight, the pilot encountered difficulty lowering the landing gear after several attempts. In response, the pilot chose to execute a gear-up landing. Post-incident examination focused on the nose gear retraction and extension system.
Examination Findings
Inspection of the nose gear retraction and extension system did not reveal any material failure. The nose gear assembly was examined, and it was found that the roller aligner assembly was displaced outside of the centering track. This displacement caused the nose gear to retract into the wheel well at an angle.
Further inspection of the nose gear assembly components showed no evidence of excessive wear or fractures. All components appeared within normal operational limits, with no signs of mechanical degradation that could explain the misalignment.
Conclusion
The investigation determined that the gear-up landing was necessitated by the inability to lower the landing gear. The primary finding was the displaced roller aligner assembly, which prevented proper gear extension. No other mechanical deficiencies were identified in the system.
