An improving aviation safety record in some sectors is an impressive accomplishment. At the close of last year, 2011 became the second year in a row there were no fatal Part 121 airline accidents. Part 135 on-demand operators experienced a safety decline, however, with 50 accidents last year (16 of them fatal) versus 31 accidents (six of them fatal) the year before. Accepting the bad with the good still translates into a relentless need for training and communicating accident details to avoid repeated mishaps. While the NTSB’s job is determining a probable cause, educating the industry about the intricacies of lessons learned falls to organizations such as the Flight Safety Foundation (FSF). In San Antonio in April the foundation held its 57th annual Corporate Aviation Safety Seminar (CASS). One of the event’s speakers, NTSB Member Robert Sumwalt, said, “I’m not supposed to have favorites, but if I did, I’d have to call this conference [CASS] mine because I started out in corporate aviation.”
