Phoenix Sky Harbor Internation Airport
Aircraft Accident/Incident Report

Phoenix, Arizona 85034
Monday, April 20, 2009 17:38 MST

NTSB Narrative Summary Released at Completion of Accident

The captain reported that upon arrival at the ramp area they had to wait for marshalers to arrive so that the airplane could be guided to the gate. As the marshalers were guiding the airplane, the captain lost sight of the ground power unit (GPU) on the right side and queried the first officer several times about whether they were clear of the GPU. The first officer responded that they were clear of the GPU; however, the right engine's propeller blades struck the GPU as the marshaler was crossing his arms to stop movement. The GPU struck the fuselage and damaged the propeller assembly. Federal Aviation Administration inspectors reported that the GPU was not parked in its designated spot and was located about 7 feet aft of its required parking spot.

NTSB Probable Cause Narrative

The failure of ramp personnel and the flight crew to maintain clearance from ground equipment while taxiing. Contributing to the accident was the improper positioning of the ground equipment.
