On Friday, January 3, 1992, a Beechcraft 1900C operating CommutAir Flight 4821 crashed into a wooded hillside near Gabriels, New York while conducting an ILS approach to Runway 23 at the Adirondack Regional Airport.

[2] Shortly before the crash occurred, the aircraft had contacted CommutAir officials on the ground at the airport.

The aircraft was equipped with a cockpit voice recorder (CVR) but it was burned to the point that the data inside were not usable.

Captain St. Germain failed to stabilize the approach, cross check the instruments, and descended below the minimum altitude.

The contributing factors to the crash were weather and possible precipitation static interference, which could have caused unreliable glide slope indications.
