F-22 Fleet Remains Grounded into Fourth Month -- AIN Online
The U.S. Air Force’s F-22 Raptor fleet remains grounded into a fourth month as the Air Force Scientific Advisory Board conducts a study of the F-22 and other aircraft using onboard oxygen generation systems (Obogs). The system is the suspected cause of a fatal crash on November 16 last year of an F-22 assigned to the 525th Fighter Squadron at Joint Base Elmendorf-Richardson near Anchorage, Alaska, and other incidents in which pilots experienced hypoxia, or oxygen deprivation. The length of the safety standdown–ordered May 3–has led to concern that F-22 pilots are “losing their training edge,” reported a television station in Panama City, Fla., near Tyndall Air Force Base, the F-22 training base. Before the grounding, the F-22 fleet was restricted to flying below 25,000 feet starting in January.
