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.

CEN09CA553

The pilot reported that during the takeoff roll, approximately 35 mph, the airplane veered hard to the left. He tried to regain directional control by applying full right brake and aileron and reducing power but to no avail. The airplane departed the left side of the runway. The right wing struck PAPI (precision approach path indicator) lights and the airplane came to a halt. The airplane was substantially damaged during th impact. Postaccident examination revealed an internal mechanical failure of the left wheel, causing the wheel to seize and the tire to roll off its rim. Sideloads caused the right main landing gear to fail.

NTSB Probable Cause

The pilot's inability to maintain directional control due to an internal mechanical failure of the left wheel that caused the wheel to seize.

Full Narrative

The pilot said that during the takeoff roll on runway 29R, at approximately 35 mph, the airplane veered hard to the left. He tried to regain control by applying full right brake and aileron and reducing power but to no avail. The airplane departed the left side of the runway. The right wing struck PAPI (precision approach path indicator) lights and the airplane came to a halt southeast of taxiway A2. Post-accident examination by a mechanic and an FAA airworthiness inspector revealed an internal mechanical failure of the left wheel. The wheel seized and the tire rolled off its rim. Sideloads caused the right main landing gear to fail.
