Key Takeaways:

  • A training flight involving a private pilot and flight instructor in a Cessna 182Q with a Garmin GFC500 autopilot and Electronic Stability and Protection (ESP) ended in a fatal, uncontrolled dive.
  • Despite the NTSB concluding the flight instructor failed to maintain control, the article questions this simple explanation given the competence of both pilots and the lack of mechanical failure.
  • The article highlights the sophisticated ESP system, which provides automated control inputs even when the autopilot is disengaged and requires specific actions (like pulling a circuit breaker) to fully disable for maneuvers, implying its interaction might be a subtle factor in such accidents.

As new aircraft and avionics become more sophisticated and capable, a pilot’s learning curve becomes more complicated. Understanding how and why things work the way they do is a critical part of our training and study. Brian Sagi’s article beginning on page 12, “Automation Misbehavior,” explores some of the ramifications and remedial actions pilots should know when their equipment malfunctions. But according to the NTSB, that’s not what happened in the accident we’re about to probe.

Of course, it’s rather easy and perhaps appropriate to blame human error when something goes tragically wrong with an airplane that seemingly was performing as designed. It’s not the first time and it won’t be the last that undiscovered or obliterated evidence resulted in defaulting to blaming the humans for a bad outcome. But this accident should serve as an attention-getter for those of us who might be a little behind in learning about the sophisticated equipment in our panels, even if it’s been there a while and is seemingly well-understood.
