The pilot successfully aborted the takeoff and taxied to his hangar. ## Factual narrative The pilot stated that during the takeoff roll while accelerating through 50 knots, the airplane collided with one of a group of four deer that ran across the runway from the left to the right. He aborted the takeoff without experiencing a loss of directional control and taxied the airplane to the hangar. He further stated that the airport is fenced around the perimeter with the exception of the main driveway, which provides access to the facility. ## Aircraft - Registration: [N2184N](https://openairdocs.org/aircraft/N2184N), registered now, S/N 30-0039, built 1999 (OpenAirDocs) - Reported make and model: MOONEY AIRCRAFT CORP.
