The FAA has become sufficiently concerned about maintenance technician fatigue to take proactive measures to educate the maintenance community. The agency’s maintenance fatigue Web site (https://hfskyway.faa.gov/HFSkyway/FatigueTool.aspx) provides information on fatigue issues and tools to help technicians and management address fatigue risk.

There are “tens of thousands of aging military aircraft” flying with the world’s air forces and many of those aircraft are more than 25 years old, according to Rob McDonald, ASIS marketing director. “Many of these fleets are set to be still flying in 20 years or more, with some aircraft, such as the USAF KC-135 tankers, topping 80 years old before the last aircraft is withdrawn from service,” he said.
