ACTION: Final rule. AGENCY: The FAA is superseding Airworthiness Directive (AD) 2020–07– 17, which applied to all Saab AB, Support and Services Model SAAB 2000 airplanes. AD 2020–07–17 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2020–07–17, it has determined that new or more restrictive airworthiness limitations are necessary. This AD retains the requirements of AD 2020–07–17 and requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as specified in a European Union Aviation Safety Agency (EASA) AD. The FAA is issuing this AD to address the unsafe condition on these products. SUMMARY: This AD is effective February 15, 2022. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of February 15, 2022. The Director of the Federal Register approved the incorporation by reference of a certain other publication listed in this AD as of May 26, 2020 (85 FR 21764, April 20, 2020).

SUPPLEMENTARY INFORMATION: khammond on DSKJM1Z7X2PROD with RULES Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2021–0132, dated May 25, 2021 (EASA AD 2021– 0132) (also referred to as the MCAI), to correct an unsafe condition for all Saab AB, Support and Services Model SAAB 2000 airplanes. EASA AD 2021–0132 superseded EASA AD 2019–0263, dated October 22, 2019 (EASA AD 2019–0263) (which corresponds to FAA AD 2020– 07–17, Amendment 39–19896 (85 FR 21764, April 20, 2020) (AD 2020–07– 17)). The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2020–07–17. AD 2020–07–17 applied to all Saab AB, Support and Services Model SAAB 2000 airplanes. The NPRM published in the Federal Register on October 4, 2021 (86 FR 54663). The NPRM was prompted by a determination that new or more restrictive airworthiness limitations are necessary. The NPRM proposed to continue to require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as specified in EASA AD 2019–0263. The NPRM also 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 2021–0132. Accomplishing the maintenance or inspection program VerDate Sep<11>2014 17:25 Jan 10, 2022 Jkt 256001 revision required by paragraph (j) of this AD terminates the requirements of paragraph (g) of this AD (which restates paragraph (g) of AD 2020–07–17). The FAA is issuing this AD to address, among other things, fatigue cracking of principal structural elements (PSEs) and corrosion prevention and control. This unsafe condition, if not addressed, could result in reduced structural integrity of a PSE, and lead to loss of control of the airplane. Discussion of Final Airworthiness Directive Comments The FAA received no comments on the NPRM or on the determination of the cost to the public. Conclusion The FAA reviewed the relevant data 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 2021–0132 describes new or more restrictive airworthiness limitations for safe life limits, structural limitation items, and fuel airworthiness items, as well as certification maintenance requirements. This AD also requires EASA AD 2019–0263, which the Director of the Federal Register approved for incorporation by reference as of May 26, 2020 (85 FR 21764, April 20, 2020). 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. Costs of Compliance The FAA estimates that this AD affects 9 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: The FAA estimates the total cost per operator for the retained actions from AD 2020–07–17 to be $7,650 (90 workhours × $85 per work-hour). The FAA has determined that revising the existing maintenance or inspection program takes an average of 90 workhours 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 PO 00000 Frm 00020 Fmt 4700 Sfmt 4700 determined that a per-operator estimate is more accurate than a per-airplane estimate. The FAA estimates the total cost per operator for the new proposed maintenance/inspection program revision to be $7,650 (90 work-hours × $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 This AD will not have federalism implications under Executive Order 13132. This AD will 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 that this AD: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Will not affect intrastate aviation in Alaska, and (3) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

SUPPLEMENTARY INFORMATION: Request To Allow Credit for Earlier Revision of Service Information Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2019–03–26, Amendment 39–19578 (84 FR 7266, March 4, 2019) (AD 2019–03–26). AD 2019–03–26 applied to certain The Boeing Company Model 737–600, –700, –700C, –800, –900, and –900ER series PO 00000 Frm 00022 Fmt 4700 Sfmt 4700 Discussion of Final Airworthiness Directive Comments The FAA received comments from two commenters, including The Boeing Company and an individual, who supported the NPRM without change. The FAA received additional comments from two other commenters, including All Nippon Airways (ANA) and Aviation Partners Boeing (APB). The following presents the comments received on the NPRM and the FAA’s response to each comment. ANA requested that the proposed AD be revised to add a note to allow use of Boeing Service Bulletin 737–25–1707, Revision 1, dated May 18, 2018. ANA stated that it has some airplanes that are identified as ‘‘Group 1’’ airplanes in Boeing Special Attention Service Bulletin 737–25–1707, Revision 2, dated July 27, 2020, and on which Revision 1 of the service bulletin was accomplished. ANA added that the changes described in Revision 2 of the service bulletin do not affect the work instructions for airplanes identified as ‘‘Group 1’’ and believed that Revision 1 could also be used to comply with the proposed requirements. The FAA disagrees with the request to revise this AD to allow use of Boeing Service Bulletin 737–25–1707, Revision 1, dated May 18, 2018, as it is not necessary. Group 1 is divided into three configurations, depending on whether or not earlier revisions of Boeing Special Attention Service Bulletin 737–25– 1707, Revision 2, dated July 27, 2020, have been done. Group 1 airplanes on which Boeing Service Bulletin 737–25– 1707, Revision 1, dated May 18, 2018, has been done are defined as Group 1, Configuration 3 airplanes. The E:\FR\FM\11JAR1.SGM 11JAR1

Airworthiness Directives; Saab AB, Support and Services (Formerly 
Known as Saab AB, Saab Aeronautics) Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2020-07-
17, which applied to all Saab AB, Support and Services Model SAAB 2000 
airplanes. AD 2020-07-17 required revising the existing maintenance or 
inspection program, as applicable, to incorporate new or more 
restrictive airworthiness limitations. Since the FAA issued AD 2020-07-
17, it has determined that new or more restrictive airworthiness 
limitations are necessary. This AD retains the requirements of AD 2020-
07-17 and requires revising the existing maintenance or inspection 
program, as applicable, to incorporate new or more restrictive 
airworthiness limitations, as specified in a European Union Aviation 
Safety Agency (EASA) AD. The FAA is issuing this AD to address the 
unsafe condition on these products.

DATES: This AD is effective February 15, 2022.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of February 15, 
2022.
    The Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD as of May 
26, 2020 (85 FR 21764, April 20, 2020).

SUPPLEMENTARY INFORMATION:

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2021-0132, dated May 25, 2021 (EASA 
AD 2021-0132) (also referred to as the MCAI), to correct an unsafe 
condition for all Saab AB, Support and Services Model SAAB 2000 
airplanes. EASA AD 2021-0132 superseded EASA AD 2019-0263, dated 
October 22, 2019 (EASA AD 2019-0263) (which corresponds to FAA AD 2020-
07-17, Amendment 39-19896 (85 FR 21764, April 20, 2020) (AD 2020-07-
17)).
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2020-07-17. AD 2020-07-17 applied to all 
Saab AB, Support and Services Model SAAB 2000 airplanes. The NPRM 
published in the Federal Register on October 4, 2021 (86 FR 54663). The 
NPRM was prompted by a determination that new or more restrictive 
airworthiness limitations are necessary. The NPRM proposed to continue 
to require revising the existing maintenance or inspection program, as 
applicable, to incorporate new or more restrictive airworthiness 
limitations, as specified in EASA AD 2019-0263. The NPRM also 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 2021-0132. Accomplishing the 
maintenance or inspection program revision required by paragraph (j) of 
this AD terminates the requirements of paragraph (g) of this AD (which 
restates paragraph (g) of AD 2020-07-17).
    The FAA is issuing this AD to address, among other things, fatigue 
cracking of principal structural elements (PSEs) and corrosion 
prevention and control. This unsafe condition, if not addressed, could 
result in reduced structural integrity of a PSE, and lead to loss of 
control of the airplane.

Discussion of Final Airworthiness Directive

Comments

    The FAA received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    The FAA reviewed the relevant data 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 2021-0132 describes new or more restrictive airworthiness 
limitations for safe life limits, structural limitation items, and fuel 
airworthiness items, as well as certification maintenance requirements.
    This AD also requires EASA AD 2019-0263, which the Director of the 
Federal Register approved for incorporation by reference as of May 26, 
2020 (85 FR 21764, April 20, 2020).
    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.

Costs of Compliance

    The FAA estimates that this AD affects 9 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:
    The FAA estimates the total cost per operator for the retained 
actions from AD 2020-07-17 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. The FAA estimates the total cost per operator for the new 
proposed maintenance/inspection program revision 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

    This AD will not have federalism implications under Executive Order 
13132. This AD will 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 that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Will not affect intrastate aviation in Alaska, and
    (3) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
