AAIB investigation to Cessna 441 Conquest II, EI-DMG

Nose landing gear not fully extended prior to landing, Prestwick International Airport, 25 June 2019.

Summary:

While landing at Prestwick International Airport it became apparent that the nose landing gear had not fully extended. The aircraft’s landing gear indication and warning system had not alerted the pilots to this unsafe condition. Upon realising the aircraft’s nose was dropping lower than normal, the pilots increased engine power and raised the aircraft nose while they activated the landing gear emergency blow-down system. The nose landing gear fully extended and the remainder of the landing was uneventful.

At the time of publication of this report, the aircraft had not been examined but it was considered likely that a faulty downlock switch on the nose landing gear actuator could provide an explanation for the failure of the nose landing gear to deploy and the absence of appropriate indications and warnings.
