Vultee Aircraft Bt-13 Valiant

Single Piston

The Vultee BT-13 Valiant was the most widely produced American basic trainer of World War II, with over 11,500 built between 1940 and 1944. Nicknamed the "Vibrator" by cadets for its characteristic engine rumble, the BT-13 served as the intermediate step between primary trainers like the Stearman and advanced combat aircraft, teaching tens of thousands of Army Air Forces pilots the fundamentals of instrument flying, formation work, and night operations. Its all-metal construction, enclosed canopy, two-way radio, and retractable landing gear made it far more representative of frontline fighters and bombers than the fabric-covered biplanes that preceded it in the training pipeline. Powered by a 450-horsepower Pratt & Whitney R-985 radial engine, the Valiant was forgiving enough for student pilots yet demanding enough to weed out those unsuited for combat flying. Today the BT-13 remains a popular warbird among collectors and living history organizations, prized for its relatively straightforward maintenance, docile handling, and authentic connection to the greatest generation of military aviators. Its distinctive sound and classic lines make it a fixture at airshows across North America. SkyMeter has tracked 20 flights across 6 airframes and 6 operators, with FLABOB AIRPORT LLC the largest observed operator.

Safety in context

The incident rate counts flights with ANY safety event detected by SkyMeter — go-arounds (a routine response, not a failure), unstable-approach gate flags (advisory thresholds), rejected takeoffs (the system working as designed), and runway events. It is NOT an accident rate or fatality rate. For accident statistics, refer to the NTSB Aviation Accident Database (USA) or the Aviation Safety Network. See methodology for what each event type measures.
