CIRRUS DOWN AT KMYF TODAY

[DCarlton]

Any remote chance the GFC500 trim problem had anything to do with this crash (since the pilot may have reported trim issues?

As per the Garmin Service Alert, Cirrus aircraft are not affected.

Wasn’t sure that note covered the entire Cirrus population.

Good point and I too wondered about that. Another MSer (who I can’t recall) posted and explained well the difference between the auto trim system in Cirrus aircraft and other aircraft that are subject to this SA.

@DCarlton I found the post but it was not on MS. If you want to read the thread in its entirety, it was on Beechtalk in the ‘Panel Talk’ section and posted by ‘Garmin Aviation Team’ under the thread, ‘Alert Garmin GFC 500 autopilot for Certified and Experimental’ and is actually the first post on page 1 of 6.

The post is quite long and reads in part, “The Cirrus SR 20 and Cirrus SR 22 aircraft are not affected. They use the original manufacturers’ pitch trim cartridge to move the pitch trim at slower speeds than the GSA 28 pitch servo.”

Thanks

Thanks for asking the question. I wondered the same thing but didn’t want to confess my ignorance! Makes me feel a lot better when fellas as intelligent as yourself have the same questions!
