Spinning the A-7

The A-7 Corsair II aircraft was introduced in the mid-sixties as the Navy’s premier attack platform. And indeed it was, as it evolved over the years to become the USAF A-7D and the Navy A-7E. The A-7 was a computer-driven machine, employing an inertial platform and a low-bypass ratio turbo-fan engine. It was truly a generational leap in air-to-ground weapons delivery technology.

But in spite of contractor assurances to the contrary, and in spite of the glitz and glamour of this shiny new machine, the A-7 had a dark side. It had a violent out-of-control mode that could be encountered in just about any portion of the airplane’s normal flight envelope. It scared the bejeezus out of pilots! The Navy lost 14 A-7’s to “out-of-control flight” in pretty short order — and half of the time we lost the pilot, too.

I was on my first tour as a test pilot in Flight Test at the Naval Air Test Center in Maryland. The Navy suddenly became intensely interested in solving the A-7 “spin problem” and funds and aircraft were made available to do the job. I was named as the primary project test pilot. Thus began a 47-flight, 350 maneuver, 2-year program to identify, define and solve the out-of-control flight problem in the A-7 airplane.

I’m enclosing a couple of videos. The first shows some of the A-7 gyrations following a vertical entry at 38,000-ft. The second video was taken on Flight #1 and shows us testing the spin recovery parachute — something we would normally use in an emergency only. The parachute was huge, and successful jettison was essential, since the airplane could not fly with the chute attached. What a weird ride that was — hanging at the end of that parachute with no control over the airplane whatsoever!
