Accident Sequence
At 1503, a twin-engine Piper PA-30 with a fuel capacity of 90 gallons received 58.15 gallons of fuel from a self-service fueling island. The aircraft was then taxied back to the pilot's hangar area. Subsequently, a jumper cable was used to connect the battery of the pilot's car to the aircraft's electrical system via the power receptacle on the left side of the nose.
At approximately 1732, with both engines running, the pilot exited the aircraft to remove the chock from the nose-wheel. The PA-30 then rolled forward (east) and eventually impacted a parked Cessna, primarily along the leading edge of the Cessna's right wing.
Collision Dynamics
Upon wing contact, the PA-30's right engine stopped. The momentum of the collision carried both aircraft in a clockwise arc a short distance to the southeast. The PA-30's left engine continued running after the collision.
At the point consistent with the PA-30's initial contact with the Cessna, a pool of blood was identified, marking the location where the pilot was first struck by the PA-30's left propeller. The pilot then dragged himself under the PA-30 to a position near the 4:30 spot, stopping close to the nose-wheel chock, which was entangled in the jumper cables.
Pilot Statement
A witness who spoke with the pilot reported that the pilot remarked, "I knew better, (unknown) was not removed, and the wind caught me."
Outcome
The pilot was airlifted to a major hospital and expired approximately 10 hours later.
