FERNANDINA BCH, FL, USA
N7059P
Piper PA-24-180
The pilot reported he entered the traffic pattern to land, and though he had a printed checklist on his lap, he did not use it. Instead he relied on his mental checklist for landing. Wearing a headset, the airplane was landed with the landing gear retracted. Postaccident testing of the landing gear extension system revealed no evidence of failure or malfunction. The landing gear 'up' light illuminated with the airplane on the runway and the master switch turned on. Also, the landing gear warning horn was heard by an FAA certificated airframe and powerplant mechanic who entered the airplane while it was on the runway, with the master switch on and the throttle at a low power position. Postaccident testing of the gear warning system in the presence of an FAA inspector revealed that the horn did not operate when the throttle was at a low power setting, the landing gear selector handle was in the 'up' position, and the master switch was turned on.
On April 22, 1999, about 1925 eastern daylight time, a Piper PA-24-180, N7059P, registered to McGill Aircraft Corporation, was landed gear up at the Fernandina Beach Municipal Airport, Fernandina Beach, Florida. Visual meteorological conditions prevailed at the time and no flight plan was filed for the 14 CFR Part 91 maintenance test flight. The airplane was substantially damaged and the private-rated pilot, the sole occupant, was not injured. The flight originated about 10 minutes earlier from the St. Mary's Airport, St. Mary's, Georgia. The pilot stated that the flight entered the traffic pattern on a left midfield downwind at a 45-degree entry and turned base then final and used a "mental" checklist but did not use the printed checklist in his lap. He further stated that he was wearing his headset and could not recall hearing the gear warning horn. He landed with the landing gear retracted. Postaccident, he reentered the airplane which was on the runway, turned on the master switch, and noted the landing gear "up" light illuminated. He determined that the airplane came to rest approximately 375 feet from the point of touchdown. With the airplane on the runway, an FAA certificated airframe and powerplant mechanic entered the airplane, turned on the master switch, and heard the gear warning horn. He advanced the throttle which silenced the horn. The airplane was raised from the runway, and the landing gear was extended using the normal extension method; the gear locked into place. Following recovery of the airplane, the landing gear system was examined in the presence of an FAA Airworthiness Inspector. The landing gear warning horn did not operate but an aural "click" sound was heard. The landing gear lights operated during the test.
The failure of the pilot to use the printed checklist which resulted in the gear-up landing. A factor associated with the accident was the intermittent failure of the gear warning horn.
