This is the 111th deployment of a Cirrus Airframe Parachute System. Report is the plane had two occupants onboard and both have been rescued safely despite the plane ending up inverted in the water.

I wonder if that massive spike in airspeed indicates a loss of control, a data glitch or perhaps a structural failure of some kind. I’d hate to think that the pilot purposefully put it into a dive...

whats odd is speed spike without a drop in altitude. if you dove, youd see the altitude drop with airspeed increasing. Unless the airspeed spike calculated is byproduct of acceleration from the chute opening.

Glad everyone’s ok!
My best friend in high school was the stepson of one of the founders of Cirrus. He was kinda a dick. W e were also fairly shitty teenager potheads so.......

T hat might have been the parachute being deployed. It’s interesting that the airspeed stayed at ~120 kts for the next minute and a half after the spike. That doesn’t seem to align with the videos I’ve seen on parachute deployments.

It’s an odd looking chart. At a glance it seems unusual to deploy the chute on a clear day, but could be a bird strike, or some kind of airframe failure.
Glad that those on board seem to have come away unscathed!

Ok so this got me curious and I looked up Cirrus’ manual.
They strongly recommend deployment when power is lost in the vast majority of situations. Basically unless you're within easy gliding distance of a runway. And even then they recommend considering it.

Imagine that, we prefer you use our product at the earliest possible moment, and we would be happy to sell you a replacement after use. :)

I was thinking it was more to do with lawyers covering the company’s butt, but there’s some strong evidence that Cirrus’ recommendation is a good one.
This is a pretty good article- AOPA is very knowledgeable on accident analysis, with the caveat that they're huge GA supporters and will never, ever, say anything actually bad about an aircraft or its manufacturer.

One of the interesting things from the FAA’s report on Roy Halladay’s fatal crash was that his plane was equipped with a parachute system, and even at low altitude he was flying at it sounded like it could have made a difference. Unfortunately, it seems like he was probably not in a mental state to activate it (or even realize he was in a situation where he’d need it). Also IIRC, he hadn’t removed the arming pin before flight, so getting it to deploy would have been more time consuming.

Need to replace a lot more than just the parachute when you use it. The initial force of the deployment sends some serious stresses through the airframe.
