Summary
Max talks with Rob Mark about the fatal crash of Cirrus SR22T N17DT near Shelbyville, Indiana, and why this accident is so instructive for any pilot who flies approaches at low altitude with high workload. The NTSB's probable cause centers on inadequate airspeed and an aerodynamic stall, but the real value is in the flight data that shows how the airplane got there: low power held for an extended period, repeated stall warnings, multiple ESP interventions, and flaps that ultimately remained retracted until impact. This episode matters because it's rare to have this level of detail. The NTSB recovered onboard data that captures dozens of parameters multiple times per second—far more than you usually get from ADS-B alone. Max describes how the NTSB published extensive graphs and also released a spreadsheet of recorded parameters. The spreadsheet didn't include position data, so Max combined it with ADS-B track points and interpolated the missing locations to create a second-by-second reconstruction. The result is a cockpit-style view that shows airspeed, pitch attitude, power, flap position, stall warning activations, and ESP engagement together—so you can see the chain of events, not just the endpoint. The key factual finding: the engine was operating normally. The "partial engine failure" theories that circulated right after the crash don't hold up against the final report and recorded parameters. Instead, power was pulled back to a very low setting—about 15%, roughly 10–11 inches of manifold pressure—and held there. That's close to a landing-power setting, which means airspeed and energy must be managed carefully to avoid drifting toward stall, especially if configuration changes. The second key finding is configuration. The flap record shows the flaps briefly at abou…
