I’ve been thinking a lot about complacency since the crash of a Gulfstream IV on takeoff from Hanscom Field in Bedford, Mass., that left seven people dead. Any accident, especially one with fatalities, affects those of us who have spent our entire lives and careers in aviation. But one that occurs at an airport where we regularly work has a particular impact. The accident investigation continues, but the National Transportation Safety Board has already issued a preliminary report that raises some troubling questions about whether the pilots conducted a routine flight control check. According to the NTSB, the flight data recorder readout shows no flight control movement that would indicate that a check was done before takeoff. The preliminary report makes no mention of such a check recorded on the cockpit voice recorder (CVR) but does state that the CVR readout indicates crew comments regarding aircraft control before the crash. The preliminary report thus raises the possibility that no flight control check was done and that a flight control problem may have been involved in causing the accident.
While it is too early to conclude that such a check was, in fact, not done, or that a problem with the flight controls led to the accident, it is not too early to consider the possibility that a highly experienced crew somehow skipped such a routine check and the implications that has for the rest of us in aviation. If this crucial step was missed, could it have been because of a complacent attitude toward checklists? Checklists are the foundation of aviation standardization and, through standardization, aviation safety. Checklists are particularly important during taxi and takeoff and during any time of high-stress activity when a pilot’s attention to detail could be diverted. But it is not unheard of for even the most experienced and highly trained among us to get complacent about the use of written checklists, even when performing safety critical functions, be they in maintenance, flying or other areas of aviation work.
