Aviation Accident Summary CHI02LA068

Iowa Falls, IA, USA

Aircraft #1

N9248D

Piper PA-22-160

Analysis

The airplane nosed over following a loss of control during landing. The pilot reported the winds were from 240 degrees at 11 knots and the landing was being made on runway 31. He reported he lowered the left wing and applied right rudder during the approach to compensate for the crosswind. The pilot reported that the airplane bounced during the landing and he did not react quickly enough by once again lowering the wing. He reported the wind lifted the left wing so that the airplane was on the right main gear only. He reported that it seemed the airplane was going to ground loop. He applied right rudder to stop the ground loop, but by that time the airplane was off the side of the runway. The airplane traveled into a plowed bean field where it nosed over and tipped onto the right wing.

Factual Information

On January 21, 2002, at 1615 central standard time, a Piper PA-22-160, N9248D, operated by a private pilot, collided with the terrain following a loss of control while landing on runway 31 (4,001 feet by 75 feet, dry asphalt) at the Iowa Falls Municipal Airport (IFA), Iowa Falls, Iowa. The pilot was not injured and the airplane was substantially damaged. The 14 CFR Part 91 personal flight was being operating in visual meteorological conditions without a flight plan. The flight originated at Dubuque, Iowa, at 1430 central standard time. The pilot reported that he checked the weather for the area surrounding IFA prior to the flight and again while en route. He reported that the winds at Waterloo, 46 miles east, were from 240 degrees at 11 knots. The pilot reported that upon reaching IFA, he flew over the airport and confirmed the winds were as he expected. He reported that he knew he was going to have a crosswind, so he lowered the left wing and applied right rudder during the approach. The pilot reported that the airplane bounced during the landing and "...since I was not expecting that I did not react quickly enough by once again lowering the wing." He reported the wind lifted the left wing so that the airplane was on the right main gear only. He reported that it seemed the airplane was going to ground loop and he applied right rudder to stop the ground loop, but by this time the airplane was off the side of the runway. The airplane traveled into a plowed bean field where it nosed over and tipped onto the right wing. Inspection of the airplane revealed the nose gear was collapsed, the propeller struck the ground, and buckling was present between the wings.

Probable Cause and Findings

The pilot's inadequate compensation for the crosswind condition and the subsequent failure to maintain control of the airplane. Factors associated with the accident were the crosswind and the rough terrain encountered.
