The FAA sent me a "Airworthiness Concern Sheet" about a Cirrus problem where the throttle levers are falling apart. Although the ACS (never saw one of those before) mentions that an AD might come out of this, I'm surprised that with 24 already identified problem throttles this isn't being treated with more urgency. Heck IIRC the FAA banished thousands of perfectly good Millennium cylinders because of a dozen or so failures.

Wow, single operator had 24 cracks. Id say that's pretty definitive that this needs to be dealt with. I'm assuming it cracks in a place where you can't just use the rest of the lever to actuate the throttle

Correct.

However, while no SN’s are listed, the early models (don’t ask me through what SN but I suspect G1-G3) are not likely affected as they have a solid metal lever, not a hollow one as shown.

Color me surprised. Faster,better,cheaper out of Cirrus. I can only hope the owners of these affected aircraft take them to task over this. Having to replace the throttle lever on the whole fleet of affected airframes is going to cost someone 7 digits.

The build quality is so poor on new aircraft it will take them years to build enough throttle levers to do an AD.

I don’t feel sorry for them. They did it to themselves.

Yup... while many SR-22 owners are waiting the 18-24 month chute maintenance backlog they can squeeze this one in? :D

Too many Tom Cruise Top Gun throttle applications?

It's rare to see a Cirrus with more than 2900 hours to begin with.
This primarily applies to 2008 and newer training aircraft, with 2900 hours or more, and 12,000 plus landings. The fleet operators beat the heck out of these planes. The older planes have a solid throttle lever.

Nah... We'll pay mid 4 digits at most. But if we all band together on our COPA forums, we can at least make it easier for Cirrus to tell us to %#$@ ourselves.
