During gear lowering, a hydraulic hose fitting separated, causing fluid loss. The pilot landed with nose gear down but main gear partially extended; main gear collapsed on touchdown, and empennage struck the runway.

Incident Overview

During the gear lowering sequence of a landing gear system, a hose fitting on the nose gear actuator gear-down hydraulic hose separated from the hose body. This failure resulted in the complete drainage of hydraulic fluid from the gear actuating system.

Pilot Actions and Landing

Following the fluid loss, the pilot was unable to move any of the landing gear from their positions at the time of the failure. The aircraft was landed with the nose gear fully extended and locked down, while both main landing gear units were only partially extended.

Touchdown and Aftermath

Upon touchdown, both main gear assemblies folded back into their respective wheel wells. The empennage subsequently contacted the runway surface. The aircraft came to rest on the runway.
