Embraer S.A. Airplanes
Superseded. A later AD replaced this one: AD 2024-16-16. Comply with the one in force.
This AD applies to Embraer S.A. Model EMB-550 and EMB-545 airplanes, certificated in any category, as identified in Agência Nacional de Aviação Civil (ANAC) AD 2020-04-01R01, effective May 22, 2020 (“ANAC AD 2020-04-01R01”).
The FAA is adopting a new airworthiness directive (AD) for certain Embraer S.A. Model EMB-550 and EMB-545 airplanes. This AD was prompted by reports of cracks, delamination, and failure of the flight deck side windows during certification fatigue tests. This AD requires repetitive inspections of the flight deck side windows for any cracking or delamination, corrective action if necessary, and eventual replacement of the windows, as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, ANAC AD 2020-04-01R01.
(1) Where ANAC AD 2020-04-01R01 refers to its effective date, or “17 April, 2020, the effective date of the original issue of this [ANAC] AD,” this AD requires using the effective date of this AD.
(2) Where ANAC AD 2020-04-01R01 refers to the compliance time of the repetitive inspections, “at each 750 Flight Hours (FH),” this AD requires a compliance time of, “at intervals not to exceed 750 flight hours.”
(3) Where ANAC AD 2020-04-01R01 refers to, “in case of no crack, delamination or any other damage which do not allow to properly perform the required inspection by this [ANAC] AD, no action is required at this time,” this AD requires that in the case of no findings in paragraphs (b)(1)(i) and (ii) of ANAC AD 2020-04-01R01, no action is required by this AD until the next inspection interval.
(4) Where ANAC AD 2020-04-01R01 refers to the compliance time for the replacement of the flight deck side windows as, “before the airplane logs 3,400 Flight Cycles Since New (FCSN),” this AD requires a compliance time of “before the airplane logs 3,400 FCSN, or within 50 flight cycles, whichever occurs later.”
(5) Replacement of the flight deck side windows as specified in paragraph (c)(1) of ANAC AD 2020-04-01R01 terminates the repetitive inspections for the flight deck side windows specified in paragraph (b)(2) of ANAC AD 2020-04-01R01.
(6) The “Alternative method of compliance (AMOC)” section of ANAC AD 2020-04-01R01 does not apply to this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
