Ninilchick, AK, USA
N6978B
Piper PA-18
The private certificated pilot was making a landing approach to a ridgeline that was oriented east/west, and was about 1,000 feet long and 30 to 100 feet wide. The pilot said he was landing toward the east. He described the wind as 10 to 15 knots from the southeast. As he approached the ground, the pilot said a burble of wind over the ridge lifted the right wing. The airplane collided with the ridge, and then nosed over. The airplane received damage to the wings, fuselage, and landing gear.
On September 16, 2003, about 1630 Alaska daylight time, a tundra tire-equipped Piper PA-18 airplane, N6978B, sustained substantial damage when it collided with the ground during the final landing approach to a remote ridgeline, about 15 miles east of Ninilchick, Alaska. The airplane was being operated as a visual flight rules (VFR) cross-country personal flight under Title 14, CFR Part 91, when the accident occurred. The airplane was operated by the pilot. The private certificated pilot, the sole occupant, received minor injuries. Visual meteorological conditions prevailed. The flight originated at Merrill Field, Anchorage, Alaska, about 1530. No flight plan was filed, nor was one required. During a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC), on September 17, the pilot reported that he was making an approach to a ridgeline that was oriented east/west, and was about 1,000 feet long, and 30 to 100 feet wide. The pilot said he was landing toward the east. He described the wind as 10 to 15 knots from the southeast. As he approached the ground, the pilot said a burble of wind over the ridge lifted the right wing. The airplane collided with the ridge, and then nosed over. The airplane received damage to the wings, fuselage, and landing gear.
The pilot's failure to maintain control of the airplane which resulted in a collision with terrain during an approach to landing on a ridgeline. Factors contributing to the accident were the pilot's inadequate evaluation of the wind conditions, and an unfavorable wind along the ridgeline.
