Confidential Business Information CBI is commercial or financial information that is both customarily and actually treated as private by its owner.
Under the Freedom of Information Act FOIA 5 U.S.C. 552, CBI is exempt from public disclosure. If your comments responsive to this NPRM
contain commercial or financial information that is customarily treated as private, that you actually treat as private, and that is relevant or responsive to this NPRM, it is important that you clearly designate the submitted comments as CBI. Please mark each page of your submission containing CBI
as PROPIN. The FAA will treat such marked submissions as confidential under the FOIA, and they will not be placed in the public docket of this NPRM. Submissions containing CBI
should be sent to Dan Rodina, Aerospace Engineer, Large Aircraft Section, International Validation Branch, FAA, 2200 South 216th St., Des Moines, WA 98198; telephone and fax 2062313225; email dan.rodina@

Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 20210134, dated June 1, 2021 EASA AD 2021
0134 also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI, to correct an unsafe condition for all Airbus SAS Model A300 series airplanes.
This proposed AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. The FAA is proposing this AD to prevent reduced structural integrity of the airplane. See the MCAI
for additional background information.
EASA previously issued EASA AD
20170207, dated October 12, 2017
EASA AD 20170207, and EASA AD
20200110R1, dated May 27, 2020
EASA AD 20200110R1, requiring the actions described in the Airbus A300
ALS, Part 2, Revision 03, and Variation 3.1, respectively. EASA AD 20170207
corresponds to FAA AD 20181917, Amendment 3919417 83 FR 48207, September 24, 2018 and EASA AD
20200110R1 corresponds to certain

actions in FAA AD 20202311, Amendment 3921327 85 FR 75838, November 27, 2020. Since those EASA
ADs were issued, Airbus published the Variation, as defined in EASA AD 2021
0134, which reduces the limit of validity LOV for Model A300
airplanes. This variation will be incorporated into the Airbus A300 ALS, Part 2, at the next revision. EASA AD
20210134 does not supersede EASA
AD 20170207 and EASA AD 2020
0110R1.
For the reason described above, this AD requires compliance with the reduced LOV as specified in the variation.
Related Service Information Under 1
CFR Part 51
EASA AD 20210134 describes new or more restrictive airworthiness limitations for airplane structures and safe life limits. This material is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section.
FAAs Determination and Requirements of This Proposed AD
This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to the FAAs bilateral agreement with the State of Design Authority, the FAA has been notified of the unsafe condition described in the MCAI referenced above. The FAA is proposing this AD
because the FAA has evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design.
Proposed AD Requirements This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, which are specified in EASA AD 20210134
described previously, as incorporated by reference. Any differences with EASA
AD 20210134 are identified as exceptions in the regulatory text of this AD.
This proposed AD would require revisions to certain operator maintenance documents to include new actions. Compliance with these actions is required by 14 CFR 91.403c. For airplanes that have been previously modified, altered, or repaired in the areas addressed by this proposed AD, the operator may not be able to accomplish the actions described in the
