Aircraft involved
Probable cause & findings
The right main landing gear’s failure to fully extend for reasons that could not be determined because postaccident testing revealed no mechanical anomalies that would have precluded normal operation.
Factual narrative
On December 3, 2017, about 1910 eastern standard time, a Piper PA-31-310, N722CF, was damaged during a wheels-up landing on runway 18 at the Clark Regional Airport (JVY), Jeffersonville, Indiana. The pilot and two passengers were not injured. The airplane received substantial damage to fuselage longerons and the aft flange of the main wing spar carry through. The aircraft was registered to Luftladder Inc. and operated by the pilot under the provisions of Title 14 Code of Federal Regulations Part 91 as a personal flight. Visual meteorological conditions existed at the time of the accident. A visual flight rules flight plan had been filed. The flight originated from the Wellsville Municipal Airport (ELZ), near Wellsville, New York, about 1630, with JVY as the intended destination. The pilot reported that when the airplane was about 5 miles from JVY, he lowered the landing gear and the right main landing gear was slow to extend, but within a few seconds all three gear down indicator lights illuminated. A normal descent was made and when the airplane was over the runway about to flare, the right main landing gear light went out. The pilot initiated a go-around, increasing engine power, pitching for climb, and retracting the landing gear and flaps. He stated that the airplane may have settled after the flaps were retracted and he heard a noise as if a propeller blade had contacted something. He decided to discontinue the go-around and landed the airplane straight ahead, coming to a stop on the runway with the landing gear retracted. After the accident the airplane landing gear was tested under the supervision of Federal Aviation Administration inspectors. Before the test, an o-ring was replaced on the hydraulic reservoir, but this would not have prevented the right main landing gear from extending. The gear retraction tests were performed satisfactorily, with no defects in the landing gear operation noted. When the airplane was about 5 miles from the airport, the commercial pilot lowered the landing gear and noted that the right main landing gear (MLG) was slow to extend, but within a few seconds, all three gear down indicator lights illuminated. The airplane descended normally, and when it was above the runway about to flare, the right MLG indicator light extinguished. The pilot initiated a go-around, increased engine power, pitched for climb, and retracted the MLG and flaps. The airplane likely settled after the flaps were retracted, and the pilot heard a noise similar to a propeller blade contacting something. The pilot decided to abort the go-around and landed the airplane straight ahead. The airplane came to a stop on the runway with the MLG retracted. Postaccident MLG retraction tests were performed satisfactorily, and no defects were noted. Based on the available information, the reason that the right MLG did not fully extend and lock could not be determined. Source: NTSB Aviation Accident Database Retrieved: 2026-02-12
