# NTSB BFO94LA117: Beech F33A, N6728X, Quarryville, PA, June 26, 1994 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: June 26, 1994, 13:30 local (17:30 UTC) - Place: Quarryville, PA - Coordinates: 39.889514, -76.159286 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=39.8895&lon=-76.1593&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report December 7, 1994 - Report: Approved by Office Director - NTSB case key (mKey): 8945 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=BFO94LA117 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/8945/pdf - Page: https://openairdocs.org/ntsb/BFO94LA117 ## Probable cause THE PILOT'S FAILURE TO TOUCHDOWN AT THE PROPER POINT AND HIS DELAYED REMEDIAL ACTION. A FACTOR RELATED TO THE ACCIDENT WAS A TAILWIND. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Overrun, landing - roll - weather condition - tailwind (contributing factor) - proper touchdown point - not attained, pilot in command (cause) - On ground/water collision with object, landing - aborted - remedial action - delayed, pilot in command (cause) - object - fence ## Analysis AS THE PILOT APPROACHED THE GRASS AIRSTRIP, HE OBSERVED THAT A VARYING CROSSWIND EXISTED FOR LANDING. HE CHOSE THE RUNWAY THAT HE THOUGHT THE WIND WAS FAVORING, AND HE TOUCHED DOWN ON THE FIRST THIRD OF IT. THE PILOT STATED THAT AT TOUCHDOWN, THE AIRPLANE WAS 'GOING FASTER THAN USUAL' BECAUSE OF A TAILWIND. THE PILOT COULD NOT STOP THE AIRPLANE BEFORE IT REACHED THE END OF THE RUNWAY. AS THE AIRPLANE ROLLED INTO A WHEAT FIELD PAST THE RUNWAY THRESHOLD, THE PILOT DECIDED TO ADD FULL POWER AND TAKE OFF. THE AIRPLANE STRUCK A FENCE AND WAS SUBSTANTIALLY DAMAGED. NO PRE-IMPACT MECHANICAL DEFICIENCIES WERE REPORTED. ## Factual narrative On June 26, 1994, about 1330 eastern daylight time, a Beech F33A, N6728X, operated by the owner/pilot, collided with a fence during an aborted landing and was substantially damaged in Quarryville, Pennsylvania. The private pilot and passenger were not injured. Visual meteorological conditions prevailed and a flight plan was not filed. The personal flight was conducted under 14 CFR 91 and departed from Doylestown, Pennsylvania. The pilot reported that as he approached the grass airstrip for landing, he observed that a varying crosswind existed for landing. He chose the runway that he thought the wind conditions were favoring (runway 28) and performed a full-flap landing onto the first third of it. The pilot stated that at touchdown, the airplane was "going faster than usual" because of a tailwind. He stated that he could not stop the airplane before it reached the end of the runway. As the airplane rolled past the runway threshold and into a wheat field, the pilot decided to add full power and attempt to take off. The airplane then struck a fence despite the pilot's efforts to stop the airplane at the last moment. The pilot also stated that "...it would have been better not to have attempted the go-around...." According to an FAA aviation safety inspector from New Cumberland, Pennsylvania, the nose gear was sheered off, the firewall was bent, and both wings were damaged. No pre-impact mechanical deficiencies were found. ## Aircraft - Registration: [N6728X](https://openairdocs.org/deregistered/N6728X-2017-01-23), registration cancelled 2017-01-23, S/N CE-1023, built 1983 (OpenAirDocs) - Reported make and model: BEECH F33A - Registry model: [Beech F33A](https://openairdocs.org/model/beech-f33a) (registry code 1151425) (OpenAirDocs) - Registry engine: [Continental IO-520 series](https://openairdocs.org/engine/continental-io-520-series) (registry code 17032, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: CE1023 - Airframe hours: 1177 - Engines: CONTINENTAL IO-520 285 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Brown, W.
