Mr. Birge makes very valid points. The chute won’t save anyone in a stall spin at 300AGL. And while the Cessna 100 series are by no means spin proof they require a significant amount of coaxing to flop on their backs (I learned to fly back in the days when spins were part of the private pilot curriculum).
I wonder about the Lexington incident. By definition the chute wasn’t needed because the crew was able to land the aircraft successfully and walk away. However, had the chute deployed in the air as designed would the crew still have walked away, or would they have suffered serious spinal injuries, broken backs, etc… I am unfamiliar with the published data regarding the sink rates and G forces associated with a parachute assisted landing. I have only heard that it is designed to save lives but is rather severe.
This incident seems to reinforce the concern that, over time, pilots will choose to deploy the chutes for reasons and frequency heretofore unanticipated. While some of these decisions may prove to save their lives, how many pilots and passengers will be permanently disabled when they otherwise would have simply “walked away”.
