Navy flight training will resume in July when T-45 Goshawk trainers receive fixes to their troubled air supply, the three-star Commander, Naval Air Forces said this week.

Days after the Navy’s T-45 Goshawk trainers returned to flight under strict safety restrictions because of problems with their air supply, the service felt compelled to make them even stricter. An aircrew’s report of “minor headaches” prompted the tighter limits, a Navy spokesperson told Breaking Defense. Only one flight out of 92 over 48 hours reported such… Keep reading →

A screwed-up control valve caused the grounding of the F-35 fleet and the program office has cleared the plane for ground operations while it tests the errant valve. Meanwhile, the F-22 fleet remains grounded until early fall when the results of an investigation into possible problems with the plane’s oxygen system are completed. For more… Keep reading →
