THE CESSNA PILOT STATED HE TAXIED TOWARD THE KING AIR FROM THE REAR AND TRIED TO PASS TO THE RIGHT. AS THE CESSNA NEARED THE PARKED KING AIR, THE CESSNA PILOT REALIZED HIS LEFT WING WOULD NOT CLEAR THE KING AIR'S RIGHT WING, SO HE APPLIED RIGHT RUDDER, RIGHT BRAKE, THEN BOTH BRAKES, BUT TO NO AVAIL. AFTER THE WING TIPS COLLIDED, THE CESSNA PIVOTED FURTHER LEFT, AND ITS PROPELLER HIT THE KING AIR'S WING. THE INVESTIGATION DID NOT DISCLOSE EVIDENCE OF MECHANICAL MALFUNCTION OF THE CESSNA'S BRAKES. ## Analysis (aircraft 1) A CESSNA 172RG PILOT STARTED TO TAXI AROUND A PARKED BEECH C90 (KING AIR), BUT THE LEFT WING OF THE CESSNA HIT THE RIGHT WING OF THE KING AIR.

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. ## Aircraft 1 - Registration: [N6419V](https://openairdocs.org/aircraft/N6419V), registered now, S/N 172RG0680, built 1980 (OpenAirDocs) - Reported make and model: CESSNA 172RG - Registry model: [Cessna 172RG](https://openairdocs.org/model/cessna-172rg) (registry code 2072438) (OpenAirDocs) - Registry engine: [Lycoming O&VO-360 series](https://openairdocs.org/engine/lycoming-o-vo-360-series) (registry code 41514, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 172RG0680 - Airframe hours: 2518 - Engines: LYCOMING O-320 180 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Robert S.
