This will not answer the original question; however, I had the duty of carrying the final test result briefing forward on the USAF T-3A after our team rung out the aircraft at Edwards. Our final test results on the flying (spin) characteristics were that, with proper control inputs, the T-3A recovered easily from every entry condition (errect, inverted, left, right ...). There was NO engine issue with the USAF version, although early on ground pounders insisted that there was. There was sufficient "telegraphing" of the ensuing departure/spin to recover; however, any delay in departure prevention controls led directly to a spin. Edwards results gave no indication of an unrecoverable spin mode as indicated in this thread.
