The tractor was mowing along the taxiway lights and was travailing to the northeast, halfway on the hard surface and halfway into the grass. The tractor driver was approaching each light, lifting his mower, passing over the light and lowering the mower again to mow in between the lights. According to the tractor driver he was 'traveling in a straight line, and was sure he had not turned out in front of the approaching airplane.' At the time of impact the driver stated that he was watching the mower and did not see the airplane until after the impact. The airplane approached the tractor from behind and he was unaware that it was coming until it hit the tractor. A witness said, '...I saw aircraft N4345C, taxing on the taxiway parallel to runway 21 and 3...toward runway 21, at an excessive rate of speed, and the tractor mowing at the side of the taxiway was going in the same direction, when the aircraft hit the back of the tractor, with the left wing without trying to slow down or stop....' ## Factual narrative On March 4, 1997, about 1450 eastern standard time, a Piper PA-28-161, N4345C, registered to Consolidated Flying Service Inc., operating as a Title 14 CFR Part 91, personal local flight, crashed while taxiing for takeoff near Tampa, Florida.

The airplane then swung around, coming to a stop facing the tractor. According to the FAA inspector's, Statement of Interview with the tractor driver, he was mowing along the taxiway lights and was travailing to the northeast. The tractor was "halfway on the hard surface and halfway into the grass." The tractor driver stated that he was using the left mower to mow around the taxi lights, and that, "...he would approach each light, lift his mower, pass over the light and lower the mower again to mow in between the lights...traveling in a straight line, and was sure he had not turned out in front of the approaching airplane." The driver stated that he was watching the mower and did not see the airplane until after the impact. The airplane had approached his tractor from behind and he was "unaware that it was coming until it hit the tractor." A witness said, "...I saw aircraft N4345C, taxing on the taxiway parallel to runway 21 and 3...toward runway 21, at an excessive rate of speed, and the tractor mowing at the side of the taxiway was going in the same direction, when the aircraft hit the back of the tractor, with the left wing without trying to slow down or stop...." ## Aircraft - Registration: [N4345C](https://openairdocs.org/aircraft/N4345C), registered now, S/N 28-8416059 (OpenAirDocs) - Reported make and model: Piper PA-28-161 - Registry model: [Piper PA-28-161](https://openairdocs.org/model/piper-pa-28-161) (registry code 7102803) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 28-8416059 - Airframe hours: 6142 - Engines: Lycoming O-320-O3G 160 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Consolidated Flying Service In - Airworthiness certificate: Standard, Normal - Last inspection: Annual, February 18, 1997, 14 hours before - Departed: TPF - Airport: TPF, Peter O'Knight, runway 21, 3,400 × 100 ft, asphalt ## Flight crew As NTSB recorded them.
