Aircraft Accident/Incident Report
Aguanga, California 92536
Friday, April 17, 1998 20:05 PDT
NTSB Narrative Summary Released at Completion of Accident
The maintenance technician/pilot was returning the airplane to its owner located on a private airstrip after an annual inspection. He stated that he entered the traffic pattern by overflying the airport at 2000 (dusk), and entering on the 45 for the downwind to runway 28. As he lined up with the runway he said that he looked down at the airspeed indicator and heard a 'kunk,' at which point he noticed that the propeller had stopped. The pilot then noticed some power lines in his path, and at the same time he noticed the runway lights flicker and go out. A postaccident examination of the airplane revealed a 3- to 4-inch gash in the spinner and some marks on one propeller blade, which the pilot said 'looked like it had scraped on something.' The pilot reported 'apparently there are two rows of power lines and somehow I hit a wire on the first row.' A maintenance worker reported that none of the power lines were broken, but one had been pulled out of its support. There were no charts or publications available to the pilot to warn him of the power lines. There were no visible displaced threshold markings on the dirt strip to indicate an obstructed 20:1 or 3-degree approach to runway 28. The runway had nonstandard lighting with six red/green lights at both thresholds. Official sunset had occurred about 1924.
NTSB Probable Cause Narrative
the lack of available published information regarding obstructions and nonstandard lighting at the private airport, and the lack of a lighted and properly marked displaced threshold.
