Aircraft Accident/Incident Report
Eau Clare, Wisconsin 54703
Wednesday, December 30, 1998 18:30 CST
NTSB Narrative Summary Released at Completion of Accident
The airplane came to rest on the runway with the nose landing gear extended, and the main landing gear retracted. During an interview, the pilot reported that he did not use a written checklist to perform the before landing checks. An aircraft mechanic at the airport reported that he found the nose wheel landing gear was in the down position with the main landing gear in their gear wells, with the landing gear handle in the down position. The airplane was placed on jacks, and 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. The mechanic attributed the failure of the gear warning horn to a stiff cable which was to be replaced in accordance with a 1981 service letter, but was never complied with.
NTSB Probable Cause Narrative
the delayed gear extension by the pilot. Contributing factors were the checklist not used by the pilot, the inoperative gear warning, and the maintenance replacement of the throttle control/gear warning interconnect cable not performed by company/operator management as recommended by the manufacturer's service letter.
