A pilot experienced a loud pop and lost landing gear indication during cruise. Despite cycling the gear and a 2-g maneuver to lock the nose gear, the main gear remained retracted. The pilot landed with nose gear extended, main gear up, and the aircraft sustained damage after coming to a stop.

Incident Summary

During cruise flight, the pilot heard a loud "pop" and noticed that the landing gear UP light was no longer illuminated. Pressing the PUSH TO TEST button did not light the UP light, while the GEAR DOWN light illuminated when tested. The pilot slowed the airplane and cycled the landing gear, but the issue persisted. He then checked and reset the landing gear circuit breaker, and cycled the gear both electrically and manually.

By performing a 2-g maneuver, the pilot was able to lock the nose landing gear in the down position. However, the main landing gear remained retracted. The pilot subsequently conducted a landing with the nose gear extended and the main gears retracted. He maintained a wings-level attitude until the aircraft came to a stop approximately 250 feet down the runway.

After stopping, the aircraft leaned onto its right stabilizer, crushing some spars and ribs.

Post-Accident Examination

Post-accident examination revealed that the hydraulic nose landing gear UP hose had failed.

Probable cause
