On June 12, 1993, at 1410 Alaska daylight time, a retractable gear, wheel equipped Cessna 402 airplane, N222JA, registered to and operated by Alaska Island Air of Anchorage, Alaska, experienced a right main gear collapse during the landing roll at Kivalina, Alaska. The air taxi flight, operating under 14 CFR Part 135, departed Kotzebue and the destination was Kivalina. A company flight plan was in effect and visual meteorological conditions prevailed. The Airline Transport Certificated Pilot- in-Command, the sole occupant, was not injured and the airplane received substantial damage. According to the Pilot-in-Command, the landing was normal and during the rollout when the airplane slowed to 40 knots, the right wing settled to the runway. Examination of the airplane showed that the pivot link, which is the link between the push pull tubes and the over center link assembly, had failed. According to the Certificate Repair Station employed to repair the airplane, the landing gear system was out of rig. The Company stated they submitted an NTSB Form 6120.1/2 to the FAA FSDO Office in Fairbanks. The FSDO Office has no record of having received this form.
