This AD just dropped on my CAMP due list and shows Overdue.

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2020-12-08 for all Embraer
S.A. Model EMB-505 airplanes. AD 2020-12-08 required inspections of the mass-balance weights of
the elevators, ailerons, and rudder (flight control surfaces) and their attachment parts, and corrective
actions if necessary, and revising the airworthiness limitation section (ALS) of the maintenance
manual or instructions for continued airworthiness to incorporate new airworthiness limitations. This
AD retains the actions required by AD 2020-12-08 and requires, for certain airplanes, cleaning and
weighing certain mass-balances and installation or replacement, as applicable; and for certain other
mass-balances for certain airplanes, replacement of those mass-balances. This AD was prompted by a
determination that new applicable airplane serial numbers and new criteria for the replacement of
affected parts are necessary. The FAA is issuing this AD to address the unsafe condition on these
products.
DATES: This AD is effective April 13, 2022

Attaching the relevant AD, which went effective April 13th 2022.

The big takeaway to my understanding is that if you performed SB505-55-0004 (dated March 25, 2020) before April 13th 2022 you get credit for the new actions required by the AD (paragraphs (l), (m), and (n)). If not these are the new requirements:

I have Elliott confirming as I completed that SB before that date as well.

Quick update. If you have had the rudder, elevator and aileron weights checked under SB 505-55-0004 then all you need is a log entry tying this to AD 2022-05-22 to clear it from the due list. Duncan Aviation, who completed the SB during the 10Y provided my log entry for no charge.

Looking to see if anyone has found issues at the 60 month re-inspection following accomplishment of the SB/AD. You’re welcome to message me directly if you’re not able to talk about it in this post.

I’m getting mine done end of May at the 60mo

I had complied with the original and during my 10yr (last year) they found corrosion on the new elevator weight. I don't remember the details, but they had to argue with Embraer, of course, to get them to cover the second fix. Embraer did in the end.
