Aircraft Accident/Incident Report

Wickenburg, Arizona 85390
Thursday, May 27, 1999 7:10 MST

NTSB Narrative Summary Released at Completion of Accident

After taking off from Moreton Airpark, the pilot made a right turn to a southeasterly heading. He planned to fly down the Hassayampa riverbed before returning to Moreton. The pilot intended to demonstrate the hissing sound the aircraft made after being shutdown to the mechanic who was also onboard. This symptom had developed after the mechanic had installed new fuel bladders. They were discussing the aircraft symptom when he noticed a bright flash. Witnesses saw the aircraft flying down the Hassayampa riverbed about 10 feet agl. They described the weather at the time of the accident as clear and calm. Investigators found six aluminum electrical transmission lines spanning the Hassayampa riverbed had been broken. The lowest three wires were 24 feet higher than the riverbed at the lowest point. The next set of three wires was 3 feet higher. The wires were marked with an orange ball. Investigators found no mechanical discrepancies with the aircraft.

NTSB Probable Cause Narrative

The pilot's failure to maintain altitude/clearance from ground obstacles. A factor was the pilot's diverted attention in this accident.
