ACTION: Final rule. AGENCY: The FAA is superseding airworthiness directive (AD) 77–04–06, which applied to MesserschmittBolkow-Blohm (MBB) (now Airbus Helicopters Deutschland GmbH (AHD)) Model BO–105A and BO–105 C helicopters; AD 2002–13–06, which applied to certain Eurocopter Deutschland GmbH (ECD) (now Airbus Helicopters Deutschland GmbH (AHD)) Model BO–105A, BO–105C, BO–105 C– 2, BO–105 CB–2, BO–105 CB–4, BO–105 CS–2, BO–105 CBS–2, BO–105S, and BO–105LS A–1 helicopters; AD 2016– 25–14, which applied to certain Airbus Helicopters Deutschland GmbH (AHD) Model BO–105LS A–3 helicopters; and AD 2021–10–14, which applied to certain Airbus Helicopters Deutschland GmbH (AHD) Model BO–105A, BO– 105C, BO–105S, and BO–105LS A–3 helicopters. Since the FAA issued those ADs, new and more restrictive airworthiness limitations have been issued. This AD requires incorporating into existing maintenance records requirements (airworthiness limitations) as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD also prohibits the installation of certain part-numbered tension-torsion (TT) straps. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective January 6, 2023. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of January 6, 2023.

SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 77–04–06, Amendment 39–2835 (42 FR 9670, February 17, 1977; amended 44 FR 46783, August 9, 1979) (AD 77–04–06); AD 2002–13–06, Amendment 39–12794 (67 FR 43526, June 28, 2002) (AD 2002– 13–06); AD 2016–25–14, Amendment 39–18740 (81 FR 94944, December 27, 2016) (AD 2016–25–14); and AD 2021– 10–14, Amendment 39–21547 (86 FR 27268, May 20, 2021) (AD 2021–10–14). AD 77–04–06 applied to Messerschmitt-Bolkow-Blohm (MBB) Model BO–105A and BO–105C helicopters. AD 77–04–06 was prompted by reports of internal corrosion of the main rotor gearbox (MGB) supports, which could significantly reduce the structural strength and service life. After AD 77– E:\FR\FM\02DER1.SGM 02DER1 lotter on DSK11XQN23PROD with RULES1 Federal Register / Vol. 87, No. 231 / Friday, December 2, 2022 / Rules and Regulations 04–06 was issued, the FAA determined based on service experience and additional test investigations the total hours time-in-service (TIS) for certain part-numbered MGB supports could be increased. Accordingly, the FAA amended AD 77–04–06 by issuing Amendment 39–3528 (44 FR 46783, August 9, 1979), which increased the life limit for the MGB supports. AD 2002–13–06 applied to Eurocopter Deutschland GmbH (ECD) Model BO– 105A, BO–105C, BO–105 C–2, BO–105 CB–2, BO–105 CB–4, BO–105S, BO–105 CS–2, BO–105 CBS–2, BO–105 CBS–4, and BO–105LS A–1 helicopters, with certain part-numbered main rotor (MR) head assemblies and certain partnumbered TT straps installed. AD 2002– 13–06 was prompted by an accident in which an MR blade separated from a Eurocopter Model MBB–BK 117 helicopter due to fatigue failure of a TT strap; the same part-numbered TT strap is used on Model BO–105 helicopters. AD 2002–13–06 was also prompted by the determination that an additional life limit for certain part-numbered TT straps needed to be established. AD 2002–13–06 required creating a component log card or equivalent record and determining the calendar age, number of flights, and flight hours TIS on certain part-numbered TT straps; removing and replacing certain TT straps, and modifying certain MR heads before certain part-numbered TT straps are installed. AD 2002–13–06 also required revising the Airworthiness Limitations Schedule (ALS) of the existing maintenance manual to reflect the new life limits. AD 2016–25–14 applied to Airbus Helicopters Deutschland GmbH (AHD) Model BO–105LS A–3 helicopters with certain part-numbered TT straps installed. AD 2016–25–14 was prompted by the determination that life limits have been introduced for certain part-numbered TT straps installed on the helicopter lifting system, and during the revision of the ALS for the existing Model BO–105LS A–3 maintenance manual, the life limit for the TT strap was inadvertently deleted. AD 2016–25– 14 required inspecting the helicopter records to determine the life limit of the TT straps. Depending on the results, AD 2016–25–14 required establishing a life limit if none exists; revising the ALS of the existing maintenance manual, and creating a component history card or equivalent record to reflect this life limit; and replacing certain TT straps. AD 2021–10–14 applied to Airbus Helicopters Deutschland GmbH (AHD) Model BO–105A, BO–105C, BO–105S, and BO105LS A–3 helicopters equipped with a certain TT strap. AD 2021–10–14 VerDate Sep<11>2014 16:45 Dec 01, 2022 Jkt 259001 was prompted by the FAA’s determination that aging of the elastomeric material in a TT strap could affect the structural characteristics of the TT strap. AD 2021–10–14 required replacement of certain TT straps with serviceable parts and implementation of a new storage life limit for TT straps. The NPRM published in the Federal Register on September 7, 2022 (87 FR 54636). The NPRM was prompted by EASA AD 2021–0142, dated June 17, 2021 (EASA AD 2021–0142), issued by EASA, which is the Technical Agent for the Member States of the European Union, to correct an unsafe condition for Airbus Helicopters Deutschland GmbH (AHD), formerly Eurocopter Deutschland GmbH, Eurocopter Hubschrauber Deutschland GmbH, Messerschmitt-Bo¨lkow-Blohm GmbH; Eurocopter Canada Ltd, formerly Messerschmitt-Bo¨lkow-Blohm Helicopter Canada Limited, Model BO105 A, BO105 C, BO105 D, BO105 S, BO105 LS A–1, and BO105 LS A–3 helicopters, all variants, all serial numbers, including BO105 LS A–3 helicopters modified in accordance with EASA Supplemental Type Certificate (STC) 10039633, or previously LuftfahrtBundesamt (LBA) Germany STC EMZ NR. 0654/3058 (commercially known as ‘‘Superlifter’’). EASA AD 2021–0142 superseded a series of ADs to include EASA AD 2019–0024, dated February 4, 2019 (which prompted AD 2021–10– 14); EASA AD 2015–0042, dated March 9, 2015 (which prompted AD 2016–25– 14); EASA AD 2013–0015, dated January 16, 2013; EASA AD 2010–0153, dated July 27, 2010; LBA Germany AD 2001–281, dated October 18, 2001 (which prompted AD 2002–13–06); and LBA Germany AD 76–136/2, dated October 5, 1978 (which prompted AD 77–04–06). The NPRM proposed to require incorporating into existing maintenance records new and more restrictive requirements (airworthiness limitations), as specified in EASA AD 2021–0142. The NPRM also proposed to prohibit the installation of certain partnumbered TT straps. The FAA is issuing this AD to address the unsafe condition on these products. Additionally, the actions required to address the unsafe conditions in AD 77– 04–06, AD 2002–13–06, AD 2016–25– 14, and AD 2021–10–14 are included in ‘‘the applicable ALS,’’ as defined in EASA AD 2021–0142. Therefore, the FAA is superseding AD 77–04–06, AD 2002–13–06, AD 2016–25–14, and AD 2021–10–14 in order to reduce the burden on operators by requiring compliance with a single FAA AD in lieu of multiple FAA ADs.

Discussion of Final Airworthiness Directive Comments The FAA received no comments regarding the NPRM or on the determination of the cost to the public. Conclusion These helicopters have been approved by EASA and are approved for operation in the United States. Pursuant to the FAA’s bilateral agreement with the European Union, EASA has notified the FAA about the unsafe condition described in its AD. The FAA reviewed the relevant data and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on these helicopters. Except for minor editorial changes, this AD is adopted as proposed in the NPRM. Related Service Information Under 1 CFR Part 51 EASA AD 2021–0142 requires replacing certain components before exceeding their applicable life limit. EASA AD 2021–0142 also prohibits installing Bendix TT-strap part number 2602559, 2606576, 2604067, or 117– 14110, and requires revising the approved aircraft maintenance program (AMP) by incorporating the limitations described in ‘‘the applicable ALS’’ as defined in EASA AD 2021–0142. 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. Other Related Service Information The FAA reviewed Airbus Helicopters BO 105 Maintenance Manual (MM), Revision 31, dated December 15, 2020, for Model BO–105A, BO–105C, BO–105 D, BO–105S, and BO–105LS A–1 helicopters; Airbus Helicopters BO 105 LS A–3 MM, Revision 7, dated November 27, 2018, for Model BO–105 LS A–3 helicopters; and Airbus Helicopters MM BO 105 LS A–3 ‘‘Super Lifter’’ Appendix 010, Revision 4, dated March 28, 2019, for BO 105 LS A–3 ‘‘Superlifter’’ helicopters. This service information specifies certain actions and associated thresholds and intervals, including life limits and maintenance tasks. These requirements (airworthiness limitations) include new life limits, including cure dates and storage life limits, for certain part-numbered TT straps. E:\FR\FM\02DER1.SGM 02DER1 73918 Federal Register / Vol. 87, No. 231 / Friday, December 2, 2022 / Rules and Regulations ADs Mandating Airworthiness Limitations The FAA has previously mandated airworthiness limitations by mandating each airworthiness limitation task (e.g., inspections and replacements (life limits)) as an AD requirement or issuing ADs that require revising the ALS of the existing maintenance manual or instructions for continued airworthiness to incorporate new or revised inspections and life limits. This AD, however, requires operators to incorporate into maintenance records required by 14 CFR 91.417(a)(2) or 135.439(a)(2), as applicable for your helicopter, the requirements (airworthiness limitations) specified in EASA AD 2021–0142. The FAA does not intend this as a substantive change. For these ADs, the ALS requirements for operators are the same but are complied with differently. Requiring the incorporation of the new ALS requirements into the maintenance records, rather than requiring individual ALS tasks (e.g., repetitive inspections and replacements), requires operators to record AD compliance once after updating the maintenance records, rather than after every time the ALS task is completed. In addition, paragraph (h) of this AD allows operators to incorporate later approved revisions of the ALS document as specified in the ‘‘Ref. Publications’’ section of EASA AD 2021–0142 without the need for an alternative method of compliance (AMOC). lotter on DSK11XQN23PROD with RULES1 Differences Between This AD and the EASA AD This AD does not require compliance with paragraphs (3), (4), and (5) of EASA AD 2021–0142. EASA AD 2021–0142 is applicable to Model BO–105D helicopters, whereas this AD is not because Model BO–105D helicopters are not certificated by the FAA and are not included on the U.S. type certificate data sheet. EASA AD 2021–0142 is applicable to Model BO– 105 LS A–3 helicopters modified in accordance with EASA STC 10039633, or previously LBA Germany STC EMZ NR. 0654/3058 (commercially known as ‘‘Superlifter’’), whereas this AD applies to Model BO–105 LS A–3 helicopters modified in accordance with STC SR00043RD. Costs of Compliance The FAA estimates that this AD affects 67 helicopters of U.S. registry. Labor rates are estimated at $85 per work-hour. Based on these numbers, the FAA estimates the following costs to comply with this AD. VerDate Sep<11>2014 16:45 Dec 01, 2022 Jkt 259001 Incorporating requirements (airworthiness limitations) into existing maintenance records takes about 2 work-hours for an estimated cost of $170 per helicopter and $11,390 for the U.S. fleet. 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 has determined that 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:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 77-04-06, Amendment 39-2835 (42 FR 9670, 
February 17, 1977; amended 44 FR 46783, August 9, 1979) (AD 77-04-06); 
AD 2002-13-06, Amendment 39-12794 (67 FR 43526, June 28, 2002) (AD 
2002-13-06); AD 2016-25-14, Amendment 39-18740 (81 FR 94944, December 
27, 2016) (AD 2016-25-14); and AD 2021-10-14, Amendment 39-21547 (86 FR 
27268, May 20, 2021) (AD 2021-10-14).
    AD 77-04-06 applied to Messerschmitt-Bolkow-Blohm (MBB) Model BO-
105A and BO-105C helicopters. AD 77-04-06 was prompted by reports of 
internal corrosion of the main rotor gearbox (MGB) supports, which 
could significantly reduce the structural strength and service life. 
After AD 77-

[[Page 73917]]

04-06 was issued, the FAA determined based on service experience and 
additional test investigations the total hours time-in-service (TIS) 
for certain part-numbered MGB supports could be increased. Accordingly, 
the FAA amended AD 77-04-06 by issuing Amendment 39-3528 (44 FR 46783, 
August 9, 1979), which increased the life limit for the MGB supports.
    AD 2002-13-06 applied to Eurocopter Deutschland GmbH (ECD) Model 
BO-105A, BO-105C, BO-105 C-2, BO-105 CB-2, BO-105 CB-4, BO-105S, BO-105 
CS-2, BO-105 CBS-2, BO-105 CBS-4, and BO-105LS A-1 helicopters, with 
certain part-numbered main rotor (MR) head assemblies and certain part-
numbered TT straps installed. AD 2002-13-06 was prompted by an accident 
in which an MR blade separated from a Eurocopter Model MBB-BK 117 
helicopter due to fatigue failure of a TT strap; the same part-numbered 
TT strap is used on Model BO-105 helicopters. AD 2002-13-06 was also 
prompted by the determination that an additional life limit for certain 
part-numbered TT straps needed to be established. AD 2002-13-06 
required creating a component log card or equivalent record and 
determining the calendar age, number of flights, and flight hours TIS 
on certain part-numbered TT straps; removing and replacing certain TT 
straps, and modifying certain MR heads before certain part-numbered TT 
straps are installed. AD 2002-13-06 also required revising the 
Airworthiness Limitations Schedule (ALS) of the existing maintenance 
manual to reflect the new life limits.
    AD 2016-25-14 applied to Airbus Helicopters Deutschland GmbH (AHD) 
Model BO-105LS A-3 helicopters with certain part-numbered TT straps 
installed. AD 2016-25-14 was prompted by the determination that life 
limits have been introduced for certain part-numbered TT straps 
installed on the helicopter lifting system, and during the revision of 
the ALS for the existing Model BO-105LS A-3 maintenance manual, the 
life limit for the TT strap was inadvertently deleted. AD 2016-25-14 
required inspecting the helicopter records to determine the life limit 
of the TT straps. Depending on the results, AD 2016-25-14 required 
establishing a life limit if none exists; revising the ALS of the 
existing maintenance manual, and creating a component history card or 
equivalent record to reflect this life limit; and replacing certain TT 
straps.
    AD 2021-10-14 applied to Airbus Helicopters Deutschland GmbH (AHD) 
Model BO-105A, BO-105C, BO-105S, and BO105LS A-3 helicopters equipped 
with a certain TT strap. AD 2021-10-14 was prompted by the FAA's 
determination that aging of the elastomeric material in a TT strap 
could affect the structural characteristics of the TT strap. AD 2021-
10-14 required replacement of certain TT straps with serviceable parts 
and implementation of a new storage life limit for TT straps.
    The NPRM published in the Federal Register on September 7, 2022 (87 
FR 54636). The NPRM was prompted by EASA AD 2021-0142, dated June 17, 
2021 (EASA AD 2021-0142), issued by EASA, which is the Technical Agent 
for the Member States of the European Union, to correct an unsafe 
condition for Airbus Helicopters Deutschland GmbH (AHD), formerly 
Eurocopter Deutschland GmbH, Eurocopter Hubschrauber Deutschland GmbH, 
Messerschmitt-B[ouml]lkow-Blohm GmbH; Eurocopter Canada Ltd, formerly 
Messerschmitt-B[ouml]lkow-Blohm Helicopter Canada Limited, Model BO105 
A, BO105 C, BO105 D, BO105 S, BO105 LS A-1, and BO105 LS A-3 
helicopters, all variants, all serial numbers, including BO105 LS A-3 
helicopters modified in accordance with EASA Supplemental Type 
Certificate (STC) 10039633, or previously Luftfahrt-Bundesamt (LBA) 
Germany STC EMZ NR. 0654/3058 (commercially known as ``Superlifter''). 
EASA AD 2021-0142 superseded a series of ADs to include EASA AD 2019-
0024, dated February 4, 2019 (which prompted AD 2021-10-14); EASA AD 
2015-0042, dated March 9, 2015 (which prompted AD 2016-25-14); EASA AD 
2013-0015, dated January 16, 2013; EASA AD 2010-0153, dated July 27, 
2010; LBA Germany AD 2001-281, dated October 18, 2001 (which prompted 
AD 2002-13-06); and LBA Germany AD 76-136/2, dated October 5, 1978 
(which prompted AD 77-04-06).
    The NPRM proposed to require incorporating into existing 
maintenance records new and more restrictive requirements 
(airworthiness limitations), as specified in EASA AD 2021-0142. The 
NPRM also proposed to prohibit the installation of certain part-
numbered TT straps. The FAA is issuing this AD to address the unsafe 
condition on these products.
    Additionally, the actions required to address the unsafe conditions 
in AD 77-04-06, AD 2002-13-06, AD 2016-25-14, and AD 2021-10-14 are 
included in ``the applicable ALS,'' as defined in EASA AD 2021-0142. 
Therefore, the FAA is superseding AD 77-04-06, AD 2002-13-06, AD 2016-
25-14, and AD 2021-10-14 in order to reduce the burden on operators by 
requiring compliance with a single FAA AD in lieu of multiple FAA ADs.
    You may examine EASA AD 2021-0142 in the AD docket at 
regulations.gov under Docket No. FAA-2022-1070.

Discussion of Final Airworthiness Directive

Comments

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

Conclusion

    These helicopters have been approved by EASA and are approved for 
operation in the United States. Pursuant to the FAA's bilateral 
agreement with the European Union, EASA has notified the FAA about the 
unsafe condition described in its AD. The FAA reviewed the relevant 
data and determined that air safety requires adopting this AD as 
proposed. Accordingly, the FAA is issuing this AD to address the unsafe 
condition on these helicopters. Except for minor editorial changes, 
this AD is adopted as proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    EASA AD 2021-0142 requires replacing certain components before 
exceeding their applicable life limit. EASA AD 2021-0142 also prohibits 
installing Bendix TT-strap part number 2602559, 2606576, 2604067, or 
117-14110, and requires revising the approved aircraft maintenance 
program (AMP) by incorporating the limitations described in ``the 
applicable ALS'' as defined in EASA AD 2021-0142.
    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.

Other Related Service Information

    The FAA reviewed Airbus Helicopters BO 105 Maintenance Manual (MM), 
Revision 31, dated December 15, 2020, for Model BO-105A, BO-105C, BO-
105 D, BO-105S, and BO-105LS A-1 helicopters; Airbus Helicopters BO 105 
LS A-3 MM, Revision 7, dated November 27, 2018, for Model BO-105 LS A-3 
helicopters; and Airbus Helicopters MM BO 105 LS A-3 ``Super Lifter'' 
Appendix 010, Revision 4, dated March 28, 2019, for BO 105 LS A-3 
``Superlifter'' helicopters.
    This service information specifies certain actions and associated 
thresholds and intervals, including life limits and maintenance tasks. 
These requirements (airworthiness limitations) include new life limits, 
including cure dates and storage life limits, for certain part-numbered 
TT straps.

[[Page 73918]]

ADs Mandating Airworthiness Limitations

    The FAA has previously mandated airworthiness limitations by 
mandating each airworthiness limitation task (e.g., inspections and 
replacements (life limits)) as an AD requirement or issuing ADs that 
require revising the ALS of the existing maintenance manual or 
instructions for continued airworthiness to incorporate new or revised 
inspections and life limits. This AD, however, requires operators to 
incorporate into maintenance records required by 14 CFR 91.417(a)(2) or 
135.439(a)(2), as applicable for your helicopter, the requirements 
(airworthiness limitations) specified in EASA AD 2021-0142. The FAA 
does not intend this as a substantive change. For these ADs, the ALS 
requirements for operators are the same but are complied with 
differently. Requiring the incorporation of the new ALS requirements 
into the maintenance records, rather than requiring individual ALS 
tasks (e.g., repetitive inspections and replacements), requires 
operators to record AD compliance once after updating the maintenance 
records, rather than after every time the ALS task is completed.
    In addition, paragraph (h) of this AD allows operators to 
incorporate later approved revisions of the ALS document as specified 
in the ``Ref. Publications'' section of EASA AD 2021-0142 without the 
need for an alternative method of compliance (AMOC).

Differences Between This AD and the EASA AD

    This AD does not require compliance with paragraphs (3), (4), and 
(5) of EASA AD 2021-0142.
    EASA AD 2021-0142 is applicable to Model BO-105D helicopters, 
whereas this AD is not because Model BO-105D helicopters are not 
certificated by the FAA and are not included on the U.S. type 
certificate data sheet. EASA AD 2021-0142 is applicable to Model BO-105 
LS A-3 helicopters modified in accordance with EASA STC 10039633, or 
previously LBA Germany STC EMZ NR. 0654/3058 (commercially known as 
``Superlifter''), whereas this AD applies to Model BO-105 LS A-3 
helicopters modified in accordance with STC SR00043RD.

Costs of Compliance

    The FAA estimates that this AD affects 67 helicopters of U.S. 
registry. Labor rates are estimated at $85 per work-hour. Based on 
these numbers, the FAA estimates the following costs to comply with 
this AD.
    Incorporating requirements (airworthiness limitations) into 
existing maintenance records takes about 2 work-hours for an estimated 
cost of $170 per helicopter and $11,390 for the U.S. fleet.

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 has determined that 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.
