On Friday, August 13, 1993, at 1206 eastern daylight time, a Cessna 172RG, N6419V, piloted by Roscoe D. Draper, collided with a Beech F90, N131CD, piloted by John H. Reilly, while taxing at the Northeast Philadelphia Airport, Philadelphia, Pennsylvania. Both airplanes were substantially damaged. The two pilots and one passenger on N6419V, and the pilot of N6419V, were not injured. Visual meteorological conditions prevailed. Instrument flight plans were filed for both airplanes. The flights were being conducted under 14 CFR 91. The Cessna, N6419V, was taxing along the parking ramp to runway 24 in preparation for a takeoff. The Cessna pilot stated: "...as we neared the parked King Air, N131CD, it appeared that the Cessna left wing would not clear the King Air right wing. I applied right rudder, right brake, then both brakes...the aircraft [Cessna] continued in a left turn (downhill) until the left wing contacted the parked King Air...and pivoted left until the Cessna positioned itself under the King Air right wing...the Cessna propeller contacted the King Air right wing...the King Air idling right propeller blades contacted the Cessna...damaging all four propeller blades." The pilot of the King Air, N131CD stated: "I was parked with brakes on...engines were started, beacon on, going through checklist for departure from PNE to TTN [Trenton-Mercer County]...looked right and saw plane [Cessna] wrapped around right wing..." Post accident investigation of the Cessna brake system revealed no malfunctions.
