Computer simulations by its Boeing manufacturer have cause serious concerns for the structural integrity of its backbone. Specifically the longerons that run from aft of the canopy to the tail. In a 28 November press release, Air Force officials have been quoted as saying:
“Although the longeron area was covered in general by previous inspections as a result of the November 2 mishap, technical experts with the Warner Robins Air Logistics Center, assisting in the Accident Investigation Board, have recommended a specific inspection of the suspect area based on the recent findings. Manufacturer simulations have indicated a catastrophic failure could result in this particular area.”
It’s Groundhog Day for the F-15 fleet as it awaiting completion of the emergency inspections.
