Applicability*9
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.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
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).
Unsafe condition
This AD was prompted by reports of corrosion in the mass-balance weights of the flight control surfaces and a determination that new airworthiness limitations are necessary. The FAA is issuing this AD to address corrosion in the mass-balance weights of the flight control surfaces. The unsafe condition, if not addressed, could result in loss of mass or the detachment of the mass-balance weights, resulting in an unbalanced control surface, which could lead to flutter and loss of airplane control.
Affected ADs
This AD replaces AD 2020-12-08, Amendment 39-21143 (85 FR 36312, June 16, 2020) (AD 2020-12-08).
