Investigating agency: HCLJ Denmark
A Piper PA-46-350P bound for Oslo experienced smoke in the cockpit and the pilot decided to make an emergency landing at Aalborg. The undercarriage did not fully extended and folded during landing.

Noise and fumes, as a consequence of a failed vent/defog blower, prompted the pilot to initiate a highspeed
emergency descent and to select the landing gear into down position.
For unknown reason and most likely during the landing gear extension, the hydraulic down line fractured leaving the landing gear in a partially extended position.
The below contributed to an unsuccessful emergency extension of the landing gear:
- The unresolved condition of the perceived electrical emergency.
- The pilot not using the autopilot to fully extent.
- The pilot not fully understanding the functioning of the landing gear emergency extension system.
- The possible ambiguity of the on board JetProp emergency procedures checklist.
- The deteriorating weather conditions at Aalborg (EKYT).
- Task saturation/high workload influenced the pilot’s ability to analyse why the landing gear emergency extension was unsuccessful.
