Aircraft involved
Probable cause & findings
The student pilot's failure to execute a go-around. Factors include excessive airspeed on the final approach, and the student pilot's attempt to land beyond a safe touchdown point.
Factual narrative
On July 23, 1999, about 1830 Eastern Daylight Time, a Cessna 172G, N6017R, was destroyed when it overran the runway and impacted trees at Chandelle Estates Airport (0N4), Dover, Delaware. The student pilot was uninjured, and visual meteorological conditions prevailed at the time of the accident. No flight plan was filed for the local instructional solo flight, which was conducted under 14 CFR Part 91. According to a Federal Aviation Administration (FAA) Inspector, the student pilot was on his third solo flight, when he "landed long and fast" on Runway 4. The student pilot could not stop the airplane before it went off the end of the runway, and then into some trees. The student pilot wrote that he "had glide rate set up, and 30 degrees flaps on final." During the landing, the airplane touched down once, then "bounced and floated. I ran out of runway and headed for [a] tree...." In a separate statement, the operator wrote that the student pilot did not follow a flight school directive, which required him to initiate a go-around after reaching a prescribed mark on the runway. About 30 minutes after the accident, weather recorded at an airport 4 miles to the south included winds from 110 degrees magnetic, at 5 knots. The student pilot landed the airplane long and fast, and could not stop it before it went off the end of the runway and into some trees. The pilot was supposed to initiate a go-around once the airplane passed a prescribed mark on the runway, but did not do so.
