Background
The FAA issued AD 2021-03-03, Amendment 39-21406 (86 FR 11103,
February 24, 2021) (AD 2021-03-03), for certain ATR-GIE Avions de
Transport R[eacute]gional Model ATR72 airplanes. AD 2021-03-03 requires
revising the existing maintenance or inspection program, as applicable,
to incorporate new or more restrictive airworthiness limitations. The
FAA issued AD 2021-03-03 to address fatigue cracking and damage in
principal structural elements, which
[[Page 38240]]
could result in reduced structural integrity of the airplane.
Actions Since AD 2021-03-03 Was Issued
Since the FAA issued AD 2021-03-03, the FAA has determined that new
or more restrictive airworthiness limitations are necessary.
EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2021-0020, dated January 15, 2021
(EASA AD 2021-0020) (also referred to as the Mandatory Continuing
Airworthiness Information, or the MCAI), to correct an unsafe condition
for all ATR-GIE Avions de Transport R[eacute]gional Model ATR72
airplanes. EASA AD 2020-0020 refers to ATR ATR72 Time Limits Document.
Revision 18, dated October 9, 2020. Airplanes with an original
airworthiness certificate or original export certificate of
airworthiness issued after October 9, 2020, must comply with the
airworthiness limitations specified as part of the approved type design
and referenced on the type certificate data sheet; this AD therefore
does not include those airplanes in the applicability.
This proposed AD was prompted by a determination that new or more
restrictive airworthiness limitations are necessary. The FAA is
proposing 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.
Related Service Information Under 1 CFR Part 51
EASA AD 2021-0020 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.
FAA's 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 FAA's 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
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 retain all of the requirements of AD 2021-
03-03. This proposed AD would also require revising the existing
maintenance or inspection program, as applicable, to incorporate new or
more restrictive airworthiness limitations, which are specified in EASA
AD 2021-0020 described previously, as incorporated by reference. Any
differences with EASA AD 2021-0020 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 (e.g., inspections).
Compliance with these actions is required by 14 CFR 91.403(c). 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 revisions. In this
situation, to comply with 14 CFR 91.403(c), the operator must request
approval for an alternative method of compliance according to paragraph
(m)(1) of this proposed AD.
Explanation of Required Compliance Information
In the FAA's ongoing efforts to improve the efficiency of the AD
process, the FAA initially worked with Airbus and EASA to develop a
process to use certain EASA ADs as the primary source of information
for compliance with requirements for corresponding FAA ADs. The FAA has
since coordinated with other manufacturers and civil aviation
authorities (CAAs) to use this process. As a result, EASA AD 2021-0020
will be incorporated by reference in the FAA final rule. This proposed
AD would, therefore, require compliance with EASA AD 2021-0020 in its
entirety, through that incorporation, except for any differences
identified as exceptions in the regulatory text of this proposed AD.
Using common terms that are the same as the heading of a particular
section in the EASA AD does not mean that operators need comply only
with that section. For example, where the AD requirement refers to
``all required actions and compliance times,'' compliance with this AD
requirement is not limited to the section titled ``Required Action(s)
and Compliance Time(s)'' in the EASA AD.
Service information specified in EASA AD 2021-0020 that is required
for compliance with EASA AD 2021-0020 will be available on the internet
at <a href="https://www.regulations.gov">https://www.regulations.gov</a> by searching for and locating Docket No.
FAA-2021-0508 after the FAA final rule is published.
Airworthiness Limitation ADs Using the New Process
The FAA's process of incorporating by reference MCAI ADs as the
primary source of information for compliance with corresponding FAA ADs
has been limited to certain MCAI ADs (primarily those with service
bulletins as the primary source of information for accomplishing the
actions required by the FAA AD). However, the FAA is now expanding the
process to include MCAI ADs that require a change to airworthiness
limitation documents, such as airworthiness limitation sections.
For these ADs that incorporate by reference an MCAI AD that changes
airworthiness limitations, the FAA requirements are unchanged.
Operators must revise the existing maintenance or inspection program,
as applicable, to incorporate the information specified in the new
airworthiness limitation document. The airworthiness limitations must
be followed according to 14 CFR 91.403(c) and 91.409(e).
The previous format of the airworthiness limitation ADs included a
paragraph that specified that no alternative actions (e.g.,
inspections) or intervals may be used unless the actions and intervals
are approved as an alternative method of compliance (AMOC) in
accordance with the procedures specified in the AMOCs paragraph under
``Other FAA Provisions.'' This new format includes a ``New Provisions
for Alternative Actions and Intervals'' paragraph that does not
specifically refer to AMOCs, but operators may still request an AMOC to
use an alternative action or interval.
Costs of Compliance
The FAA estimates that this proposed AD affects 23 airplanes of
U.S. registry. The FAA estimates the following costs to comply with
this proposed AD:
The FAA estimates the total cost per operator for the retained
actions from AD 2021-03-03 to be $7,650 (90 work-hours x $85 per work-
hour).
The FAA has determined that revising the existing maintenance or
inspection program takes an average of 90 work-hours per operator,
although the agency recognizes that this number may vary from operator
to operator. Since operators incorporate maintenance or inspection
program changes for their affected fleet(s), the FAA has determined
that a per-operator estimate is more accurate than a per-airplane
estimate.
[[Page 38241]]
The FAA estimates the total cost per operator for the new proposed
actions to be $7,650 (90 work-hours x $85 per work-hour).
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. Subtitle VII: Aviation Programs,
describes in more detail the scope of the Agency's authority.
The FAA is issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701: General requirements.
Under that section, Congress charges the FAA with promoting safe flight
of civil aircraft in air commerce by prescribing regulations for
practices, methods, and procedures the Administrator finds necessary
for safety in air commerce. This regulation is within the scope of that
authority because it addresses an unsafe condition that is likely to
exist or develop on products identified in this rulemaking action.
Regulatory Findings
The FAA determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would not
have a substantial direct effect on the States, on the relationship
between the national Government and the States, or on the distribution
of power and responsibilities among the various levels of government.
For the reasons discussed above, I certify this proposed
regulation:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Would not affect intrastate aviation in Alaska, and
(3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
