On March 1, 1997, at 1155 mountain standard time, a Cessna TR182, N2396S, sustained substantial damage when the nose gear failed to extend for landing at Pueblo Municipal Airport, Pueblo, Colorado. The private pilot and passenger were not injured on this personal flight operating under 14 CFR Part 91. No flight plan was filed and visual meteorological conditions prevailed. The flight departed Alamosa, Colorado, at 1115. This was the first flight after repairing the nose landing gear following a ground incident which occurred on February 21, 1997. The flight departed Alamosa with the pilot occupying the left seat and his 2 year old daughter in a car seat strapped in the right seat. On arrival in Pueblo, the nose gear failed to extend. After attempts to lower the gear failed, the pilot elected to raise the landing gear and landed with all the landing gear in the up position. Examination of the aircraft by a certified repair station following the accident revealed the nose gear doors were not properly adjusted when maintenance was performed on the landing gear following the previous incident. The lack of proper adjustment prevented the nose landing gear from extending. Aircraft damage was to the left wing and underside of the fuselage in the area of the nose landing gear assembly.
