JSF programme spokesman Joe Dellavedova said the crack was consistent with analytical predictions, both in terms of location and life.
“Resolving durability test article findings is a well-understood process. Durability testing is conducted early in the development of any new aircraft to avoid costly sustainment issues later in the life of the aircraft.
“Problems are found and corrected in development rather than fleet service,” Dellavedova added.
The JSF programme will incorporate new modified forward root rib design in to 30 conventional take-off and landing (CTOL) and 34 short take-off and vertical landing (STOVL) aircraft.
