Citing an increase in aircraft accidents involving loss of control (LOC), the FAA issued Information for Operators 10010, which calls for operators to incorporate upset recovery training. “Although the overall accident rate has decreased, the category of LOC continues to outpace other factors as the leading cause of fatal accidents in the last 20 years,” the FAA said. LOC is defined as “flight outside the normal flight envelope, with nonlinear influences, and with an inability of the pilot to control the aircraft.” As a result of the steady increase in LOC-related accidents, the agency “strongly recommends” that operators include applicable sections of the FAA/Boeing-developed Airplane Upset Recovery Training Aid in their training programs. However, the FAA noted, “Any LOC recommended recovery techniques and procedures provided by a manufacturer for a particular aircraft take precedence over those in the training aid."
