According to Air Combat Command accident investigation boards a Predator and Reaper unmanned aerial vehicle crashed because of a quill shaft bearing failure and an improperly assembled oil system temperature control valve, respectively. The MQ-1 Predator that crashed Oct. 19, 2008, just short of Ali Base in Iraq was destroyed upon impact. The failure of its quill shaft bearing caused the UAV’s variable pitch propeller to change pitch leading it to reverse thrust. The bearing apparently had been used “beyond the designed specifications,” according to the ACC release. The MQ-9 Reaper crashed March 20 of this year at Ft. Irwin, Calif., when it suffered “a severe oil flow imbalance which resulted in engine failure,” stated the ACC release. The improper assembly of the aircraft’s oil system temperature control valve caused the oil flow imbalance.

As the Air Force moves forward with its efforts to operationalize the concept of agile combat employment, leaders need to embrace an iterative approach that builds on itself, recognizing that ACE may never be fully complete, said Chief of Staff Gen. Charles Q. Brown Jr.
The Defense Department released its annual report on civilian casualties, the first since the department came under increased pressure to better mitigate the harm of U.S. operations and assess their aftermath. The report details 12 total deaths from U.S. forces in 2021.
China’s approach to developing a sixth-generation fighter is similar to that of the Air Force—a family of systems with an “exponential” improvement in stealth over current platforms—and China both knows how to pursue that technology and is moving rapidly to develop it iteratively, Air Combat Command chief Gen.

The Air Force should take a rapid but iterative, building-block approach to developing the concept of Collaborative Combat Aircraft--uncrewed airplanes that will aid the crewed ones with sensing, jamming and carrying weapons--or it may get the concept expensively wrong, Air Combat Command's Gen. Mark D. Kelly said Sept. 21. It's…
