The warning wasn’t in the tailplane. It was in the threads. On Alaska Airlines Flight 261, inadequate lubrication allowed the jackscrew’s threads to wear down until they could no longer carry the load. A hidden maintenance issue became a catastrophic loss of control. Why do you think lubrication and inspection intervals matter so much in aviation? Save this for your next engineering deep dive. #AviationSafety #EngineeringFailures #AlaskaAirlines261 #AircraftMaintenance #MechanicalEngineering #AviationHistory #SafetyEngineering - @amazeifystore
