Probable cause
The failure of the landing gear to extend due to the failure of a hydraulic line.
Findings · 1
NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.
Sequence of events
The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.
Analysis
While en route, the left and right hydraulic system failure lights illuminated. The pilot diverted to an alternate airport. The pilot was unable to extend the landing gear using the normal system. The pilot tried the emergency system but the gear still would not extend. The pilot was forced to land wheels up after diverting to an alternate airport. The airplane's keel sustained substantial damaged during the landing. An examination of the airplane showed a hydraulic line had failed downstream of the left and right hydraulic pumps and the emergency landing gear extension air bottle, making gear extension impossible.
Factual narrative
While en route, the airplane's left and right hydraulic system failure lights illuminated. The pilot diverted to an alternate airport.
