FACTORS WHICH CONTRIBUTED TO THE ACCIDENT WERE: THE WET RUNWAY AND THE PILOT'S INATTENTIVENESS DUE TO FATIGUE. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, landing - roll - airport facilities,runway/landing area condition - wet (contributing factor) - directional control - not maintained, pilot in command (cause) - fatigue, pilot in command (contributing factor) - ground loop/swerve - inadvertent, pilot in command - Nose over, landing - roll ## Analysis THE PILOT REPORTED THAT DURING LANDING HE LOST DIRECTIONAL CONTROL, AND THE AIRPLANE GROUND LOOPED AND NOSED OVER. HE ALSO REPORTED THAT THE RUNWAY WAS WET FROM A RECENT RAINSHOWER, AND THERE WAS SOME STANDING WATER ON THE RUNWAY. IN ADDITION, HE REPORTED THAT HE HAD BEEN FLYING FOR MOST OF THE DAY AND WAS TIRED. ## Factual narrative On June 5, 1994, at 1930 eastern daylight time, a Great Lakes 2T-1A, N849K, nosed over following a loss of control during a landing at the Gwinnett County Airport (Briscoe Field), in Lawrenceville, Georgia. The private pilot was not injured, and the aircraft was substantially damaged. The aircraft was operated under 14 CFR Part 91 by the pilot. Visual meteorological conditions existed at the time, and no flight plan was filed for the personal flight. The flight originated in Gadsden, Alabama at 1720 central daylight time. The pilot had reported that he had participated in a biplane fly- in on the day of the accident, and had been flying for most of the day. He commented that he was not attentive to the landing, and the aircraft veered to the right. The aircraft ground looped, resulting in structural damage to the upper wing, vertical stabilizer, and rudder. He reported no mechanical malfunction or failure with the aircraft. An inspector with the Federal Aviation Administration visited the accident site and inspected the aircraft. He reported that the wheel brakes and flight controls were in operable condition. The pilot reported to him that during the landing, the runway was wet from a recent rainshower, and there was some standing water on the runway. The pilot also reported that he had been flying for most of the day, and was tired. ## Aircraft - Registration: N849K (not matched to a registry record) - Reported make and model: GREAT LAKES 2T-1A - Category: Airplane - Serial number: 113 - Airframe hours: 529 - Engines: LYCOMING O-360 180 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Webb, Jones - Registered owner: Webb, Jones - Airworthiness certificate: Special, Provisional (Special); Standard, Normal - Last inspection: Annual, November 30, 1993 - Departed: GAD, GADSDEN, AL - Airport: LZU, Briscoe Field, runway 7, 6,000 × 100 ft, asphalt ## Flight crew As NTSB recorded them.

Ground looped on landing. Nosed over. Light crosswind. Pilot blamed fatigue. From the NTSB's public API. 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. Compare the reported make and model. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/). It is not affiliated with the FAA or the NTSB.
