A pilot reported a low voltage light and dimming, was cleared to turn right, but turned left toward terrain. The aircraft struck trees at about 1,225 ft MSL. Switches were found off; alternator tested normal.

Incident Overview

About 10 minutes after takeoff, while at 6,000 feet mean sea level (MSL), the pilot radioed air traffic control, stating that the low voltage light was on and that dimming was occurring, requesting vectors back to Burlington. The controller cleared the pilot direct to Burlington and instructed a right turn to heading 010. However, the pilot executed a left turn toward high terrain, descended, and the airplane impacted trees on a mountain at an elevation of approximately 1,225 feet MSL.

Impact and Wreckage

The initial contact with trees occurred about 65 feet above ground level. The aircraft continued for about 538 feet, shedding parts before coming to rest. Examination of the wreckage revealed that the master, battery, and alternator switches were in the 'off' position. A portable transceiver was found with its switch in the 'on' position. No flashlight was found in the wreckage.

System Testing

Subsequent testing of the alternator did not reveal any evidence of malfunction. The source does not specify any additional findings regarding the electrical system or the cause of the low voltage indication.
