1996-11-05: Grumman American AA-1B (N9926L) — Gaithersburg, MD

Gaithersburg, MD, US

On November 5, 1996, a Grumman American AA-1B (registration N9926L) was involved in an aviation accident near Gaithersburg, MD. Investigators recorded the probable cause as: the pilot's inadequate preflight, and his failure to detect an insufficent fuel supply, which resulted in fuel exhaustion and a forced landing after takeoff. Uneven terrain (drop-off in the emergency landing area) was a related factor. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A pilot and passenger experienced an engine power loss at about 200 feet during takeoff. The airplane impacted terrain, skidded across a road, and nosed over. An FAA inspector found no mechanical issues and no fuel in the aircraft or at the scene.

Accident Details

The pilot last flew the airplane approximately 45 days before the accident. Based on fuel purchased before a previous flight, he estimated the left wing fuel tank was one-third full and the right wing tank was half full. During the preflight inspection, the pilot removed the fuel caps but was unable to see fuel due to the tank design. When a prospective buyer arrived, both individuals boarded the airplane and taxied to the runway. The engine runup, takeoff roll, and rotation were normal.

At about 200 feet above ground level, the engine lost power. The pilot initiated a left turn back toward the runway. The airplane impacted the ground, skidded across a raised road, continued down a steep grade, and nosed over. The pilot and passenger exited the airplane through the rear window openings. The pilot could not recall looking at the fuel sight gauges in the cockpit before takeoff.

Post-Accident Findings

An FAA inspector examined the engine and found no mechanical problem. The inspector also stated that no fuel could be found in the airplane or at the accident scene.
