|Faulty Steel Causes Fatal F111 Crackup
WASHINGTON (AP)--The Air Force said Monday a piece of faulty
steel in a wing led to the 15th crash of an F111 aircraft last Dec. 22
at Nellis Air Force Base, Nev.
The accident killed two crewmen and led to grounding of all the
variable sweep F111s.
The victims were Thomas J. Mack, 38, formerly of Viola, and a son
of Mr. and Mrs. Bert Mack of Viola, and Major John Anthony of Big Springs, Tex.
Secretary of the Air Force Robert C. Seamans Jr. said
investigation showed the accident was caused by structural failure of
the left wing "stemming from a pre-existing defect in the steel
used in a pivot fitting where the wing joins the fuselage."
The Air Force said it will inspect its more than 200 F111s to
seek whether they have similar defects. Until those inspections are
completed, the plane will remain grounded.
