2004-07-05: Lake LA-4-200 (N6248V) — Stephen Young — Wilmot, NH

Wilmot, NH, US

On July 5, 2004, a Lake LA-4-200 (registration N6248V) operated by Stephen Young was involved in an aviation accident near Wilmot, NH. Investigators recorded the probable cause as: The pilot's continued VFR flight into IMC conditions, and his failure to maintain terrain clearance, which resulted in a controlled flight into terrain. Factors in the accident were the low cloud ceiling and the pilot's lack of recent instrument time. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A pilot flying VFR impacted a mountain after encountering instrument conditions. The pilot reported the accident as controlled flight into terrain. No mechanical issues were found.

Accident Details

A pilot operating under visual flight rules (VFR) departed and initially flew beneath a cloud layer at an altitude approximately 500 to 800 feet above the trees. When visual conditions deteriorated, the pilot continued flying using instruments, maintaining an altitude of 3,500 feet mean sea level (msl). Shortly thereafter, the airplane collided with terrain about 500 feet from the summit of a 2,937-foot mountain. When asked about the cause, the pilot stated, "Controlled flight into terrain."

Weather and Visibility

Witnesses reported that at the time of the accident, the mountain was obscured by a cloud layer extending from its summit down to approximately 2,000 feet. Lateral visibility was reported to be about 200 feet.

Pilot Information

The pilot had obtained an instrument rating five years prior to the accident. In the five years since, the pilot logged a total of 5.4 hours of instrument time during four flights. The most recent instrument experience was three years before the accident, when the pilot recorded 0.5 hours of actual instrument time.

Aircraft Examination

An examination of the airplane revealed no pre-impact mechanical deficiencies.
