Incident Summary
The airplane came to rest on the runway with the nose landing gear extended and the main landing gear retracted. No further details about the flight or aircraft were provided in the investigation source.
Pilot Interview
During an interview, the pilot reported that he did not use a written checklist to perform the before-landing checks. The source did not specify what checks were performed or omitted.
Mechanic Inspection
An aircraft mechanic at the airport reported that after the incident, he found the nose wheel landing gear in the down position, with the main landing gear retracted into their gear wells. The landing gear handle was observed in the down position.
Gear System Check
The airplane was placed on jacks for further examination. When the master switch was placed into the 'ON' position, the red gear-in-transit light illuminated, the landing gear extended, and the green gear-down light illuminated. The gear was then cycled approximately six times and operated normally.
Maintenance Issue
The mechanic attributed the failure of the gear warning horn to a stiff cable. According to the mechanic, the cable was scheduled for replacement in accordance with a 1981 service letter, but that replacement had never been complied with. The source did not state whether this cable issue was directly responsible for the gear malfunction.
