A factor in this accident was the improper recovery from a bounced landing. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Hard landing, landing - flare/touchdown - flare - misjudged, pilot in command (cause) - recovery from bounced landing - improper, pilot in command (contributing factor) - In flight collision with terrain/water, landing - roll - terrain condition - ditch - terrain condition - drop-off/descending embankment ## Analysis After flying in the local area for about 30 minutes, the flight returned to the departure airport, and landed. The airplane impacted the runway, bounced twice, skidded off the left side of the runway, hit a ditch and embankment. The pilot attempted to make the takeoff with full flaps, but immediately retracted all the flaps when the aircraft would not climb. ## Factual narrative On July 24, 1999, about 1330 eastern daylight time, a Beech C23, N63TW, registered to N63TW LTD., was substantially damaged while landing at Oconee County Airport, Clemson, South Carolina. The private-rated pilot and two passengers reported no injuries. Visual meteorological conditions (VMC) prevailed in the vicinity, and no flight plan had been filed. The local personal flight was being conducted in accordance with Title 14 CFR Part 91. The flight had originated from the same airport, about 1300. The pilot said that he had been flying in the local area for about 30 minutes. Upon return to the departure airport the airplane landed on runway 7, and bounced. The pilot added power to go around, the airplane lifted off the ground, and then settled back onto the runway. The airplane then departed the runway, and struck a ditch. According to the FAA's report, "...the airplane impacted the runway, bounced twice, stalled and skidded off the left side of the runway, hit a ditch and embankment, came to rest near the departure end...the pilot used a poor recovery technique...[he] attempted to make the takeoff with full flaps, and immediately dumped all the flaps when the aircraft would not climb...." ## Aircraft - Registration: [N63TW](https://openairdocs.org/deregistered/N63TW-2015-05-13), registration cancelled 2015-05-13, S/N M-1762, built 1976 (OpenAirDocs) - Reported make and model: Beech C23 - Registry model: [Beech C23](https://openairdocs.org/model/beech-c23) (registry code 1151242) (OpenAirDocs) - Registry engine: [Lycoming O&VO-360 series](https://openairdocs.org/engine/lycoming-o-vo-360-series) (registry code 41514, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: M-1762 - Airframe hours: 1764 - Engines: Lycoming O-360-A4J 180 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: N63tw Ltd./Capital Aircraft - Airworthiness certificate: Standard, Normal - Last inspection: Annual, June 16, 1999 - Departed: CEU - Airport: CEU, Oconee County Regional, runway 7, 4,156 × 75 ft, asphalt ## Flight crew As NTSB recorded them.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
