Federal Register / Vol. 86, No. 35 / Wednesday, February 24, 2021 / Proposed Rules
the FAA proposes to amend 14 CFR part 39 as follows:
PART 39AIRWORTHINESS
DIRECTIVES
1. The authority citation for part 39
continues to read as follows:

Authority: 49 U.S.C. 106g, 40113, 44701.
39.13

Amended
2. The FAA amends 39.13 by adding the following new airworthiness directive:

Airbus SAS: Docket No. FAA20210028;
Project Identifier MCAI202001516T.
a Comments Due Date The FAA must receive comments on this airworthiness directive AD action by April 12, 2021.
b Affected Airworthiness Directives ADs None.
c Applicability This AD applies to all Airbus SAS Model A319171N airplanes, Model A320271N, 272N, and 273N airplanes, and Model A321271N, 272N, 271NX, and 272NX
airplanes, certificated in any category.
d Subject Air Transport Association ATA of America Code 71, Powerplant.
e Reason This AD was prompted by a report indicating that during a full scale fatigue test of the forward engine mounts, premature wear was identified on the forward engine mount shackle assemblies; in addition, during bearing replacement, the bearing lock washer was found broken. The FAA is issuing this AD to address premature wear and broken bearing lock washers at the forward engine mounts, which could lead to overload of the forward engine mount beams and engine mount failure, with consequent in-flight engine detachment, and possibly result in reduced controllability of the airplane.
f Compliance Comply with this AD within the compliance times specified, unless already done.

ACTION: Supplemental notice of proposed rulemaking SNPRM;
reopening of comment period.
AGENCY:

The FAA is revising an earlier proposal for certain The Boeing Company Model 767200, 300, 300F, and 400ER series airplanes.

The FAA is proposing this airworthiness directive AD to address the unsafe condition on these products.
Since these actions would impose an additional burden over that in the NPRM, the FAA is reopening the comment period to allow the public the chance to comment on these changes.
DATES: The comment period for the NPRM published in the Federal Register on November 7, 2019 84 FR
60007, is reopened.
The FAA must receive comments on this SNPRM by April 12, 2021.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
