The Pilot Mistake That Killed 4 Generations!

Hey, it's Hoover! I've got a weekly letter for you on the patterns that keep killing pilots. Free → https://pilotdebrief.com/pattern On a snowy November morning in 2019, a Pilatus PC-12 lifted off from a small South Dakota airport with twelve people aboard a ten-seat airplane — four generations of one family heading home from a hunting trip. It climbed to 380 feet before everything came apart. The airplane had sat outside overnight at Chamberlain Municipal Airport through light snow and freezing drizzle. Before the flight, the pilot used a seven-foot ladder to clear the wings, but the horizontal stabilizer was out of reach. He told a witness the remaining ice would "come off during takeoff." Low IFR conditions and moderate icing AIRMETs were in effect. The loading was the bigger problem. Twelve occupants filled an airplane certified for ten seats, putting it roughly 107 pounds over max gross weight and four to five and a half inches beyond the aft CG limit. Recorder data later showed the previous flight — same loading, no contamination — had produced similar pitch oscillations, pointing to the weight and balance as the underlying issue rather than the ice alone. Rotation came at about 88 knots, four knots below the icing-configuration speed, with an abrupt and heavy pull on the column. The stall warning and stick shaker activated one second after liftoff. The airplane entered a left turn, airspeed decayed from the mid-90s into the low 80s, and the bank angle reached 64 degrees at a peak altitude of 380 feet AGL. About 22 seconds after liftoff, the wing exceeded its critical angle of attack and the airplane departed controlled flight, impacting a corn field three-quarters of a mile west of the runway. The NTSB found the loss of control resulted from an inadvertent low-altitude aerodynamic stall, with the improper loading reducing static longitudinal stability and the decision to depart into low IMC contributing to the outcome. The pattern here is what makes this case worth studying. The contamination is the headline, but the simulations showed the airplane could have been controlled until the stall — it was the aft CG, the heavy weight, the early rotation, and the abrupt pitch input compounding together that drove the angle of attack past the limit. Each decision in isolation might have been survivable. Stacked, they weren't. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ JOIN THE DEBRIEF CREW ON PATREON Ad-free videos and exclusive analysis From $5/month:   / pilotdebrief   ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ SOURCES NTSB Accident ID: CEN20FA022 Status: Final Final Report: https://data.ntsb.gov/carol-repgen/ap...

Every video on this channel analyzes publicly released NTSB final reports, factual narratives, CVR/FDR transcripts, and docket evidence to extract practical safety lessons for general aviation pilots. We do not speculate beyond the evidence. We do not blame pilots for being human.
