Aviation safety reports, made easier to study

NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.

The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.

The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

According to the pilot, the preflight inspection was performed and an engine run-up was "completely successful" on the supercharged engine. He advanced the throttle to "full power," noted 2,050 rpm and 20 inches (expecting 2,200 rpm and 32 inches) and released the brakes for the ground roll. After an 800-foot ground roll, the pilot noted 55 miles per hour, 2,100 rpm, and 28 inches. The airplane drifted to the right and the pilot attempted to correct with the application of left rudder and aileron control. The airplane became airborne and the left wing contacted the ground. The airplane settled back to the ground and headed towards the left side of the runway, at which time the pilot elected to abort the takeoff. The airplane became airborne one additional time, departed the runway environment to the left, and impacted several trees, resulting in substantial damage. Density altitude at the time of the accident was estimated to be 11,570 feet. An examination of the airplane systems revealed no anomalies.

Full Narrative

According to the accident report form submitted by the pilot, the preflight inspection was performed and an engine run-up was "completely successful" on the supercharged engine. He advanced the throttle to "full power," noted 2,050 rpm and 20 inches (expecting 2,200 rpm and 32 inches) and released the brakes for the ground roll. After an 800 foot ground roll, the pilot noted 55 miles per hour, 2,100 rpm, and 28 inches. The airplane drifted to the right and the pilot attempted to correct with the application of left rudder and aileron control. The airplane became airborne and the left wing contacted the ground. The airplane settled back to the ground and headed towards the left side of the runway, at which time the pilot elected to abort the takeoff. The airplane became airborne one additional time, departed the runway environment to the left, and impacted several trees. Both leading edges were crushed aft, crushing multiple ribs, and wrinkling the leading edge skin. Several stringers and both sides of the horizontal stabilizer sustained impact damage. Density altitude at the time of the accident was estimated to be 11,570 feet. An examination of the airplane systems revealed no anomalies. According to the owner of the airplane, 2,100 rpm and 27 inches was not abnormal for that make and model of airplane at that altitude.
