Incident Overview
On July 27, 2021, at about 1105 eastern daylight time, a Socata TBM-700 C2, registration N48UM, was substantially damaged after overrunning the runway at Mount Pleasant Regional Airport-Faison Field (LRO) in Mount Pleasant, South Carolina. The private pilot and five passengers were not injured. The flight was conducted under Title 14 Code of Federal Regulations Part 91 as a personal flight.
Pilot Account
According to the pilot, the visual approach was "uncomfortably fast." The aircraft crossed the threshold of the 3,700-foot-long runway at 125 to 130 knots and touched down between the first third and the middle third of the runway. The pilot 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 aircraft came to rest approximately 325 feet past the end of the runway.
Examination Findings
A Federal Aviation Administration inspector examined 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. The brakes showed 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.
Performance Data
According to the Pilot's Information Manual (PIM), with flaps in the landing position, the landing distance on a wet runway would have been about 2,700 feet. The PIM recommended an approach speed of 80 knots and a touchdown speed of 65 knots. The pilot's reported approach speed was approximately 30 to 40 knots higher than the recommended approach speed.
Pilot's Safety Recommendation
In the "Operator/Owner Safety Recommendation" section of the NTSB form, the pilot stated: "when it was apparent that the approach was not stabilized, I should have performed a go-around."
