Aircraft Accident/Incident Report

Greeley, Colorado 80631

NTSB Narrative Summary Released at Completion of Accident

After takeoff and during climb out, the pilot heard an unusual noise, "like a chain popping or slipping around a sprocket" when the landing gear was retracted. He then noticed the left main tire and inboard gear doors were visible beneath the engine nacelle. Unable to extend or retract the landing gear, the pilot diverted to another airport and made an intentional wheels up landing. Later disassembly and examination of the nose landing gear actuator (p/n 50-820208-5) revealed the nut assembly had been painted white while it was in the EXTEND position. After cleaning off the paint and reassembling the actuator, it moved freely in and out as required. The disassembly report stated, "The nut assembly is a chromed metal shaft that is not to be painted." According to the operator, the airplane had recently been repainted.

NTSB Probable Cause Narrative

jamming of the nose landing gear actuator due to improper painting procedures by other maintenance personnel which resulted in a wheels up landing.
