A FACTOR RELATED TO THE ACCIDENT WAS: THE PROXIMITY OF A PARKED AIRPLANE TO THE RUNWAY. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - In flight collision with object, approach - vfr pattern - final approach - object - vehicle - visual lookout - inadequate, pilot in command (cause) - unsafe/hazardous condition - disregarded, driver of vehicle (cause) - landing gear,main gear - overload - Loss of control - on ground/water, landing - roll - directional control - not possible, pilot in command - ground loop/swerve - uncontrolled - On ground/water collision with object, landing - roll - object - aircraft parked/standing (contributing factor) ## Analysis WHILE ON SHORT FINAL TO LAND, THE LEFT MAIN GEAR CONTACTED THE ROLL BAR ON A BULLDOZER WHICH WAS ON A FLAT BED TRAILER BEING PULLED BY A TRUCK. THE TRUCK HAD BEEN DRIVEN OUT OF A PARKING LOT NEXT TO THE RUNWAY AND TURNED ONTO A ROAD WHICH WAS 30 FEET FROM THE APPROACH END OF THE RUNWAY. THE PILOT STATED HE NEVER SAW THE TRUCK UNTIL AFTER HE LANDED. AFTER LANDING, THE AIRPLANE VEERED TO THE LEFT, TRAVELED OFF THE RUNWAY, AND CONTACTED A PARKED CESSNA 170 AIRPLANE. THE DRIVER OF THE TRUCK REPORTEDLY SAW THE AIRPLANE, BUT WAS NOT CONCERNED. ## Factual narrative On November 11, 1994, at 1126 central standard time, a Beech G35, N4469D, registered to Ernest Burnell of Fontana, Wisconsin, and flown by a private pilot, was substantially damaged during landing at the Frankfort Airport, Frankfort, Illinois. The personal flight was operating under CFR 14 Part 91. Visual meteorological conditions prevailed and no flight plan was filed. The pilot and one passenger were not injured, a second passenger received minor injuries. The flight originated from East Troy, Wisconsin, on November 11, 1994, at 1100 central standard time. While on short final approach to land on runway 09, N4469D contacted the roll bar of a bullbozer which was on a flat-bed trailer being pulled by a truck. The truck had pulled out of a parking lot next to the runway and turned south on a road which is located just off the approach end of the runway. The left main gear was damaged on contacting the bulldozer. The pilot continued flying the airplane and landed on runway 09. Upon touchdown, according to the pilot, the airplane veered abruptly to the left and departed the north side of the runway. N4469D traveled through the grass into a tie down area where it contacted a parked Cessna 170. The pilot stated he did not see the truck prior to the collision as it was hidden under the wing of the airplane. According to the pilot, the driver of the truck saw the airplane but did not think anything about it. The end of the runway is approximately 30 feet from the road. ## Aircraft - Registration: [N4469D](https://openairdocs.org/deregistered/N4469D-2012-11-30), registration cancelled 2012-11-30, S/N D-4609, built 1956 (OpenAirDocs) - Reported make and model: BEECH G35 - Registry model: [Beech G35](https://openairdocs.org/model/beech-g35) (registry code 1151516) (OpenAirDocs) - Registry engine: [Continental E225 series](https://openairdocs.org/engine/continental-e225-series) (registry code 17015, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 4609 - Airframe hours: 3905 - Engines: CONTINENTAL E225-8 225 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Ernest L.
