Airworthiness Directive · Amendment 39-21964 · Elevator structure
Embraer S.A. (Type Certificate Previously Held by Empresa Brasileira de Aeronáutica S.A.) Airplanes
This AD applies to Embraer S.A. (type certificate previously held by Empresa Brasileira de Aeronáutica S.A.) Model EMB-505 airplanes, all serial numbers, certificated in any category.
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.
This paragraph restates the requirements of paragraph (g) of AD 2020-12-08, with no changes. For airplanes with a serial number listed in Embraer Alert Service Bulletin SB505-55-A004, Revision 5, dated December 12, 2019 (Embraer SB505-55-A004R5): At the applicable compliance time specified in paragraph (g)(1), (2), or (3) of this AD, accomplish the actions required by paragraph (h) of this AD.
(1) For airplanes with a serial number listed in Group 1 of Embraer SB505-55-A004R5: Within 3 calendar days or 5 hours time-in-service (TIS), whichever occurs first, after July 1, 2020 (the effective date of AD 2020-12-08).
(2) For airplanes with a serial number listed in Group 3 of Embraer SB505-55-A004R5: Within 30 calendar days or 50 hours TIS, whichever occurs first, after July 1, 2020 (the effective date of AD 2020-12-08).
(3) For airplanes with a serial number listed in Group 2 of Embraer SB505-55-A004R5: Within 60 calendar days or 100 hours TIS, whichever occurs first, after July 1, 2020 (the effective date of AD 2020-12-08).
This paragraph restates the requirements of paragraph (h) of AD 2020-12-08, without the requirement to report information to Embraer. For airplanes with a serial number listed in Embraer SB505-55-A004R5, at the applicable time specified in paragraph (g) of this AD: Do the inspections identified in paragraphs (h)(1) through (6) of this AD and, before further flight, install or replace the mass-balance, as applicable, and replace the attachment parts, in accordance with Parts I through VI and Part VIII, as applicable, of the Accomplishment Instructions of Embraer SB505-55-A004R5; except, where the service information tells you to submit information to Embraer, this AD does not require that action.
(1) Do an inspection of the elevator horn mass-balance weights and attachment parts for corrosion and fragmentation, and weigh each mass-balance.
(2) Do an inspection of the elevator internal mass-balance weights and attachment parts for corrosion and fragmentation, and weigh each mass-balance. You must remove and weigh the mass-balance weight even if there is no sign of corrosion or material fragmentation.
(3) Do an inspection of the elevator adjustable mass-balance weights and attachment parts for corrosion and fragmentation, and weigh each mass-balance.
(4) Do an inspection of the aileron mass-balance weights and attachment parts for corrosion and fragmentation, and weigh each mass-balance. You must remove and weigh the mass-balance weight even if there is no sign of corrosion or material fragmentation.
(5) Do an inspection of the rudder adjustable mass-balance weights and attachment parts for corrosion and fragmentation, and weigh each mass-balance.
(6) Do an inspection of the rudder internal mass-balance weights and attachment parts for corrosion and fragmentation, and weigh each mass-balance. You must remove and weigh the mass-balance weight even if there is no sign of corrosion or material fragmentation.
This paragraph restates the requirements of paragraph (i) of AD 2020-12-08, with no changes. Within 10 days after July 1, 2020 (the effective date of AD 2020-12-08), revise the airworthiness limitations section (ALS) of the existing maintenance manual or instructions for continued airworthiness to add the information in table 1 to paragraph (i) of this AD and the initial compliance time information in table 2 to paragraph (i) of this AD.
This paragraph restates the requirements of paragraph (j) of AD 2020-12-08, with no changes. After the ALS has been revised as required by paragraph (i) of this AD, no alternative inspection intervals may be approved, except as provided in paragraph (p) of this AD.
For the purposes of this AD, “since new” is defined as since the date of issuance of the original airworthiness certificate or the original export certificate of airworthiness.
