    AD 2022-5-12 Elevator & Aileron Mass Balance Weight (Updated)

    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:

    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.
