SUPPLEMENTARY INFORMATION:
Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 20210020,
PO 00000

Frm 00005

Fmt 4700

Sfmt 4700

64805

dated January 15, 2021 EASA AD
20210020 also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI, to correct an unsafe condition for all ATRGIE
Avions de Transport Regional Model ATR72 airplanes.
The FAA issued a notice of proposed rulemaking NPRM to amend 14 CFR
part 39 to supersede AD 20210303, Amendment 3921406 86 FR 11103, February 24, 2021 AD 20210303.
AD 20210303 applied to certain ATR
GIE Avions de Transport Regional Model ATR72 airplanes. The NPRM
published in the Federal Register on July 20, 2021 86 FR 38239. The NPRM
was prompted by a determination that new or more restrictive airworthiness limitations are necessary. The NPRM
proposed to require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as specified in EASA AD 20210020.
The FAA is issuing this AD to address fatigue cracking and damage in principal structural elements, which could result in reduced structural integrity of the airplane. See the MCAI
for additional background information.
Discussion of Final Airworthiness Directive Comments The FAA received a comment from the Air Line Pilots Association, International ALPA, who supported the NPRM without change.
Conclusion The FAA reviewed the relevant data, considered the comment received, and determined that air safety requires adopting this AD as proposed. Except for minor editorial changes, this AD is adopted as proposed in the NPRM.
None of the changes will increase the economic burden on any operator.
Accordingly, the FAA is issuing this AD
to address the unsafe condition on these products.
Related Service Information Under 1
CFR Part 51
EASA AD 20210020 describes new or more restrictive airworthiness limitations for airplane structures and safe life limits.
This AD also requires EASA AD
20200173, dated August 5, 2020, which the Director of the Federal Register approved for incorporation by reference as of March 31, 2021 86 FR
11103, February 24, 2021. This material is reasonably available because the interested parties have access to it through their normal course of business
