Incident Details
A flight instructor (CFI) was providing training to an instrument-rated commercial pilot. During a practice missed approach, the landing gear failed to retract after selection.
Emergency Procedures
The crew attempted to lower the landing gear using all available emergency procedures. Despite these efforts, the landing gear system did not respond normally.
Fly-by Inspection
A fly-by of the control tower was conducted to visually inspect the landing gear position. Tower personnel reported that the main landing gears were extended and locked, while the nose landing gear was observed to be in transit—neither fully up nor fully down.
Landing and Collapse
Subsequently, the pilots performed a landing. During the landing rollout, the nose landing gear collapsed as soon as it made contact with the runway surface.
Cause
Examination revealed that the landing gear malfunction was the result of a ruptured hydraulic fluid line. The depletion of hydraulic fluid rendered the landing gear system inoperable, preventing normal extension and locking of the nose gear.
