An AT-6D Texan (N29678) crashed near Bronson, Florida on April 13, 2026 at approximately 1536 EDT, killing both occupants during a formation flight training exercise conducted under the auspices of the North American Training Association (NATA). Among the fatally injured was Justin Westbrooks, the pilot receiving the formation checkout, a Delta Air Lines captain qualified on the Boeing 757 and 767 who had begun his professional aviation career at Embry-Riddle Aeronautical University in 2009. The NTSB preliminary report indicates the accident airplane was operating as the second aircraft in a two-ship formation, in extended trail position approximately one-half mile behind the lead aircraft, during the final segment of the training sequence. As the formation descended through 2,700 feet MSL on a southerly heading, the lead aircraft performed two 180-degree direction changes followed by two circles that terminated in a 30-degree climbing, 30-degree banked attitude. The lead pilot observed the accident airplane transitioning to a nose-high attitude with right bank, then briefly diverted attention to clear his own turn, and upon looking back observed the accident airplane in an approximately 80-degree nose-down descent. Below roughly 1,000 feet AGL, the aircraft rolled right approximately 3.5 times, indicating a developed spin. The lead pilot reported the aircraft appeared to be initiating a recovery just before ground impact, which was followed by a post-impact fire. Flight control continuity was confirmed throughout the airframe, with cable fractures consistent with overload, suggesting no pre-impact mechanical anomaly.
The probable accident sequence points to a classic secondary stall scenario during an attempted spin recovery at critically low altitude. In the AT-6 Texan, the stall is characteristically abrupt — the left wing drops sharply and the aircraft enters a spin readily once the critical angle of attack is exceeded with even minor yaw input. These handling qualities were intentional by design, as the T-6 was engineered to prepare World War II-era pilots for high-performance fighters such as the P-51 Mustang and F4U Corsair, all of which carried similarly unforgiving departure characteristics. While the AT-6 is recoverable from a spin, the altitude loss during recovery is substantial. The preliminary report and analysis strongly suggest that as the aircraft descended in the spin and the ground rushed upward, the pilot applied aggressive back pressure in an attempt to arrest the descent — pulling beyond the critical angle of attack before the spin had been fully neutralized. This would induce a secondary stall, resetting or deepening the spin at an altitude from which recovery was no longer possible. This phenomenon is well-documented in both military and civilian upset recovery training literature: a pilot conditioned by normal flight to associate nose-low, high-speed descent with "pull" will often override the correct spin recovery inputs when confronted with ground proximity and sensory urgency.
The operational context carries significant implications for the professional aviation community. Westbrooks was not an inexperienced aviator — he was a type-rated airline captain with substantial turbine time. This underscores a critical distinction between professional airline or business aviation competency and the specialized skill set required for formation flying and aerobatic-adjacent maneuvering. High-hour professional pilots moving into warbird or formation flying environments routinely underestimate the degree to which their existing training does not transfer. Airline and Part 91/135 pilots spend careers flying envelopes specifically designed to preclude departure from controlled flight; recovery from developed spins, particularly in high-torque tailwheel aircraft, requires a separate and perishable skill domain. NATA's formation training program represents the civilian standard for standardizing these skills, and the fact that this is the organization's first fatality across its clinic history speaks to the rigor of its curriculum — but also underscores that the training environment itself, while managed, carries inherent risk that demands full pilot respect and disciplined execution.
For formation flight operators and pilots, this accident renews the conversation about altitude minimums, maneuver constraints, and briefing specificity in trail formation segments. Extended trail formation at a half-mile spacing introduces significant energy management variables compared to close fingertip formation, and the lead aircraft's dynamic maneuvering — multiple 180-degree turns, circles, and climbing turns — creates a demanding chase-plane environment. Whether extended trail and the specific maneuver sequence were explicitly briefed and risk-assessed prior to departure is a question the full NTSB investigation will likely examine. The NATA model requires pre-flight briefings that account for each element of the formation sequence; any deviation or improvisation in maneuver execution in a training context introduces compounding hazard. Operators running Part 91 formation training programs, whether through NATA clinics or independently, should treat the briefing as a binding contract, with hard floor altitudes for any maneuvering from which spin entry is possible — and those floors must account for full spin recovery altitude loss in the specific aircraft type, not generic estimates.
The broader trend this accident reflects is the continued growth of warbird and high-performance piston ownership and operation among professional pilots who are highly credentialed in the Part 121 or Part 135 environment but may have limited exposure to departure-from-controlled-flight scenarios. The warbird community has worked for years to build structured training pipelines through organizations like NATA precisely because the consequences of informal self-instruction in these aircraft are severe. The AT-6 Texan, one of the most common warbird types in civilian hands, rewards proficiency and punishes complacency with very little margin between the two. For corporate flight departments and individual professionals considering type transitions into high-performance piston or warbird aircraft, this accident is a stark reinforcement that professional currency in swept-wing jets does not substitute for type-specific aerobatic and upset training — and that maintaining that training once acquired is not optional.
