NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The private pilot, who was also a mechanic with an inspection authorization, was landing the airplane from a ferry flight after the airplane had been involved in a previous accident (see ANC99LA155). The pilot/mechanic said that immediately after touchdown, the nose wheel began to vibrate. The nose gear assembly collapsed, and the engine firewall to which the temporary nose gear assembly had been attached, sustained substantial damage. Inspection by an FAA airworthiness inspector revealed that a nose landing gear assembly from an earlier model Cessna 182 had been installed without a shimmy damper, and without provision for connection to the steering bungees. A doubler had been installed on the previously damaged firewall to provide mounting structure for the nose gear assembly. A review of photographs taken at the first accident site revealed that substantial damage to the left wing, left horizontal stabilizer and left elevator (including missing the outboard 4 inches of elevator, and the left elevator tip counterweight), tail cone and empennage, and lower engine cowling existed prior to the ferry flight. The FAA issued a ferry permit for the airplane but did not inspect the airplane, nor verify the extent of damage which existed prior to the flight occurring. The airplane had received its last annual inspection on July 18, 1997, 26 months before the first accident.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot/mechanic's improper damage repair, and intentional operation (ferry) of the airplane with known deficiencies. Factors in the accident were the installation of the improper nose gear assembly, and the inadequate surveillance and issuance of a special flight permit by the FAA.
