being made away from personal skill and responsibility to a systems approach. This went too far as I will explain later in my conclusions. At this time, fl ight safety was still very much considered to be related
to pilot capability, depending on a pilot’s skill to overcome equipment failures and operational challenges. Accident investigators blamed pilot error when no other cause could be found. But some people began

to think in terms of preventing accidents rather than fi nding a cause and apportioning blame after the fact. This thinking began to be applied to the maintenance work world as well. In both military and civilian
aviation in the ’60s and ’70s we had lots of manuals and procedures. I remember taking only one very short course about a maintenance control manual and then it was back to work. We all knew we had to complete logbooks, snag sheets, etc., but our safety-system knowledge was sparse at the working level. The addition of new trades based on the electronics revolution meant that many old-time aviation personnel were being replaced by newcomers without the intensive background previous technicians had. The was aggravated by the more complex jet powered aircraft that had arrived that overtook the aviation business. Therefore, management systems were needed to ensure the new generation of technicians understood the entire system. This led to applying the newly developing quality control philosophy to aviation maintenance work.

QUALITY ASSURANCE By the late nineteen fi fties industrial mangers searching for more reliability and durability came to develop the organized principles of quality control. Courses were developed and taught in colleges and universities. The general principle was that detailed manuals of procedures supported by direct inspection and statistical analysis of problems would lead to better products. It did, but of course soon led to a more mature system called Quality Assurance which relied more on systems and procedures rather than inspection. This led to much more regulatory eff ort on maintenance control
