US Air Force sees $100 million to fix F-22 problem
The U.S. Air Force said it will spend $100 million to fix the aft boom, where the horizontal tail of the plane attaches to the fuselage.
It denied a report that the problem affects 100 aircraft and costs $1 billion.
Some 41 aircraft would be retrofitted beginning in January to fix the weakness, while improvements to 32 more jets would be incorporated into the production line.
66 of those planes were also affected by a separate issue involving the plane's forward boom, where the wing attaches to the fuselage, where fatigue testing revealed that titanium used there was not properly heat-tested.
