More cracks found in F-15s
St. Louis Post-Dispatch
Cracked support beams have been found in two more F-15s, the Air Force said this morning.
The planes, based in Okinawa, were among 30 inspected there in the wake of a second grounding of older F-15s announced last week. The cracks were in the upper support beams, called longerons, behind the cockpit, the same place where cracks have been found in several other planes during recent inspections and where an F-15C apparently broke apart over southern Missouri last month.
The St. Louis-built fighter jets, a major piece of the Air Force’s air-to-air combat fleet, are mostly at least 25 years old and are nearing the end of their service life. Hundreds have been grounded for inspection and, perhaps, repair, since last month’s crash.
