N48UM

On July 27, 2021, about 1105 eastern daylight time, a Socata TBM-700 C2, N48UM, was substantially damaged when it was involved in an accident at Mount Pleasant Regional Airport-Faison Field (LRO) Mount Pleasant, South Carolina. The private pilot and five passengers were not injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight.

According to the pilot, his visual approach was “uncomfortably fast.” The airplane crossed over the threshold of the 3,700-ft-long runway at 125 to 130 knots and touched down on “the first 1/3 to the middle 1/3 of the runway.” He applied brakes, but the runway was wet and slick. Unable to stop on the remaining runway, the pilot attempted to move the throttle from beta to full to abort the landing, but the throttle “stuck.” The airplane subsequently came to rest about 325 ft past the end of the runway.

According to the Federal Aviation Administration inspector who responded to the accident site and conducted an initial examination of the wreckage, the engine mounts and left wing sustained substantial damage. The flaps were found in the “TAKEOFF” position. All engine and flight controls were intact from the cockpit controls to their respective control surfaces and functioned normally. In addition, examination of the brakes revealed no anomalies. The throttle lever had no binding and operated smoothly through its full range of motion. A pilot’s abbreviated checklist, a quick reference performance guide, and a laminated checklist were located on the airplane, but no Pilot’s Information Manual (PIM) was on board the airplane.

According to the PIM, with the flaps in the landing position, the landing distance on a wet runway would have been about 2,700 ft; the PIM recommended an approach speed of 80 knots and a touchdown speed of 65 knots. The pilot’s reported approach speed was about 30 to 40 knots over the PIM recommended approach speed.

The pilot reported in the "Operator/Owner Safety Recommendation" section of the Pilot/Operator Aircraft Accident/Incident Report (NTSB form 6120.1/2) that "when it was apparent that the approach was not stabilized, I should have performed a go-around.”
