NTSB Factual Report

On March 6, 2010, about 1415 central standard time, a Hawker Beechcraft Corp. A36, N1114X, piloted by a commercial pilot, sustained substantial damage when its landing gear collapsed during a touch and go on runway 22R (3,201 feet by 75 feet, asphalt) at the Lawrence J. Timmerman Airport (MWC), near Milwaukee, Wisconsin. The pilot was uninjured. The flight was conducted under the provisions of Title 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed at the time of the accident and no flight plan was on file for the flight. The flight originated from the Hartford Municipal Airport, near Hartford, Wisconsin, about 1400 and was destined for MWC.

The pilot reported that he performed a touch and go on runway 15L at MWC without incident. The tower then switched him to runway 22R for the next touch and go. He reported that he touched down successfully and “normalized” the airplane for takeoff. He said, “With full power and before breaking ground the gear inadvertently raised.”

A Federal Aviation Administration inspector examined the airplane on-scene. The landing gear handle was found selecting the up position. The airplane was raised and the landing gear lowered when electrical power was turned on in the airplane and the landing gear handle was placed in the down position. No mechanical anomalies were detected with the landing gear system that would have precluded normal operations.

The airplane's take-off checklist, in part, stated, "Landing Gear - RETRACT (when positive rate-of-climb is established)"

NTSB Probable Cause

The pilot's retraction of the landing gear prior to establishing a positive climb rate.
