Aviation Accident Summary CHI04LA087

Peru, IL, USA

Aircraft #1

N15118

Piper PA-28R-200

Analysis

The airplane was substantially damaged when the dual student inadvertently selected the landing gear lever during landing rollout. The right main gear subsequently collapsed and the airplane departed the right side of the runway. The dual student reported that after landing the instructor asked him to raise the flaps. He stated that he inadvertently selected the gear switch instead of the flap lever. He noted: "The gear switch was not moved to the complete up position before the instructor announced and I realized my error." The right main landing gear collapsed, causing the aircraft to veer to the right and off the side of the runway. The nose gear subsequently collapsed and the aircraft came to rest in the grass adjacent to the runway. During a post-accident inspection, the landing gear system was activated by using the cockpit gear switch and the landing gear retracted and extended as designed. The squat switch was determined to be installed and adjusted in accordance with the manufacturer's requirements. Electrical functionality of the switch was tested and no anomalies were observed.

Factual Information

On March 13, 2004, about 1530 central standard time, a Piper PA-28R-200, N15118, piloted by a flight instructor and a dual student, was substantially damaged when the right main landing gear collapsed during landing rollout on runway 18 (6,000 feet by 100 feet, asphalt), at the Illinois Valley Regional Airport (VYS), Peru, Illinois. The dual student was a non-current private pilot receiving instruction in preparation for a flight review. The instructional flight was operating under 14 CFR Part 91 without a flight plan. Visual meteorological conditions prevailed at the time of the accident. The flight instructor, dual student and passenger did not report any injuries. The local flight departed VYS approximately 1400. In his written statement, the dual student reported that they had practiced airwork in the local area prior to returning to VYS. He noted that the landing was smooth and after about a 300-foot ground roll, the instructor asked him to raise the flaps. He stated that he "inadvertently reached for the gear switch on the front panel instead of the flap lever between the seats. The gear switch was not moved to the complete up position before the instructor announced and I realized my error." He reported that the right main landing gear collapsed and the aircraft veered off the right side of the runway. The nose gear subsequently collapsed before the aircraft came to a stop. The flight instructor, in his written statement, reported that the dual student landed the aircraft "very smooth" on the runway centerline. He stated that during the landing roll he asked the student to raise the flaps, however, the student "accidentally grabbed the landing gear lever, probably pulling it at least partially out." A Federal Aviation Administration inspector conducted a post-accident inspection. With the aircraft elevated on jacks stands, the landing gear system was activated by using the cockpit gear switch and the landing gear retracted and extended as designed. The squat switch was determined to be installed and adjusted in accordance with the manufacturer's requirements. Electrical functionality of the switch was tested and no anomalies were observed.

Probable Cause and Findings

The inadvertent landing gear retraction by the dual student during the landing roll.
