BEECH C23

Full Narrative

The pilot reported that two private airports were in close proximity to one another, and he mistakenly landed at the wrong airport. He added that once he realized his mistake, he referenced the Federal Aviation Administration (FAA) chart supplement and visual flight rules (VFR) sectional chart and observed a published runway length of 2,600 ft. for departure. The pilot reported that he referenced the pilot's operating handbook (POH) and noted that the calculated takeoff distance was 1,350 ft.

The pilot reported that during the takeoff roll, he decided to abort the takeoff with about half of the runway remaining, because the airplane had not reached the speed he expected. During the aborted takeoff, the airplane pulled to the left of the runway centerline "slightly" when the brakes were applied, and the left wing struck two fence posts along the runway. The collision with the fence posts pulled the airplane off the runway surface to the left and into a ditch and a barbed wire fence.

The left wing sustained substantial damage.

The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.

The FAA Aeronautical Information Services Office was asked by the National Transportation Safety Board investigator-in-charge to evaluate the published runway dimensions at the accident airport. Upon review, the FAA determined the runway dimensions provided for the airport should have been 2,483 ft. x 25 ft., rather than 2,600 ft. x 25 ft. The FAA submitted the revised dimensions to the National Flight Data Center for publication.

According to takeoff performance calculations with the FAA Koch Chart, the airplane would have likely experienced a 60% increase to the normal takeoff distance. When factoring in this increase with the airplane's POH takeoff distance chart, the ground roll required was about 1,808 ft. and the total distance to clear a 50 ft. obstacle was 3,128 ft. Numerous trees were located at the end of the runway. The distance to clear the 50 ft. obstacle exceeded the published runway length and revised runway length.
