I've spent a decent amount of time at Centennial; it's one of the busiest general aviation airports in the country. There's a great restaurant on site that you can watch the runways from. After this incident, the restaurant is probably as close as I'd get to a Cirrus. :)

The more generic system is called BRS, Ballistic Recovery Systems. They deliver this as an option for many small aircraft and it's popular for experimental / home built aircraft. One downside of the systems is that they typically have a maximum lifespan of 10 years while airframes last 50+ years. So every 10 years there is a large maintenance cost to replace/renew the parachute system. Much less an issue for a $ 800k…

Am I correct in saying after one usage, the parachute system generally needs replaced? I think I read this about Cirrus planes anyway

I believe the whole airplane needs to be replaced after BRS use.

Bloody hell: the state of that Metroliner. Surprised it held together with that amount of damage, and huge kudos to the pilots for getting it on the ground safely.

For such a serious accident this seems about the best possible outcome for the crew of both aircraft. I'm not an expert so I'm not going to comment on root cause or blame here, but simply glad to read that at least everybody survived.

It may sound pointless unless you consider that the pilot will not need to be replaced.

> Cirrus originally thought that the airframe would be damaged beyond repair on ground-impact, but the first aircraft to deploy (N1223S) landed in mesquite and was not badly damaged. [1]

The pilot is speaking about failed engine after the collision, like it is nothing. Fascinating. I'd be shouting something obscene in such a situation. For half an hour at least, I think.

There's the issue that in many cases people tried to save the airframe rather than activate the parachute, knowing the aircraft was likely to be written off, and died doing so. It the same when the pilot is equipped with a parachute.
