Background The FAA issued AD 2022–14–14, Amendment 39–22119 (87 FR 43403, July 21, 2022), (AD 2022–14–14), for all serial-numbered Alexander Schleicher GmbH & Co. Segelflugzeugbau Model ASW–15 gliders. AD 2022–14–14 was prompted by MCAI originated by EASA, which is the Technical Agent for the E:\FR\FM\10NOP1.SGM 10NOP1 67838 Federal Register / Vol. 87, No. 217 / Thursday, November 10, 2022 / Proposed Rules Member States of the European Union. EASA issued EASA AD 2021–0187, dated August 9, 2021 (EASA AD 2021– 0187), for all Alexander Schleicher GmbH & Co. Segelflugzeugbau Model ASW 15 gliders to correct an unsafe condition identified as wing root rib damage. AD 2022–14–14 requires repetitively inspecting the wing root ribs for cracks, looseness, and damage and replacing any root rib with a crack, a loose rib or lift pin bushing, or any damage. The FAA issued AD 2022–14–14 to detect and correct damaged root ribs. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2022–1303. Actions Since AD 2022–14–14 Was Issued Since the FAA issued AD 2022–14– 14, Alexander Schleicher GmbH & Co. Segelflugzeugbau determined that Model ASW–15B gliders can also be affected by wing root rib damage. As a result, EASA superseded EASA AD 2021–0187, and issued EASA AD 2022– 0146, dated July 11, 2022 (referred to after this as ‘‘the MCAI’’). The MCAI states that wing root rib damage can also affect Model ASW–15B gliders and the Model ASW–15B as well as the ASW– 15 gliders require repetitively inspecting the wing root ribs and replacing any damaged wing root ribs. The MCAI retains the requirements of EASA AD 2021–0187 and expands the applicability to include all Model ASW– 15B gliders. Related Service Information Under 1 CFR Part 51 The FAA reviewed Alexander Schleicher GmbH & Co. Segelflugzeugbau ASW 15 Technical Note No. 29, Issue II (TN No. 29, Issue II), dated May 4, 2022. This service information specifies replacement of root ribs. This proposed AD would also require Alexander Schleicher GmbH & Co. Segelflugzeugbau ASW 15 Technical Note No. 29, dated June 28, 2021; Alexander Schleicher GmbH & Co. Segelflugzeugbau ASW 15 Repair instruction exchange of wing root ribs according to TN 29, dated June 28, 2021; and Alexander Schleicher GmbH & Co. Segelflugzeugbau ASW 15 Maintenance Instruction G, Issue 1, dated June 28, 2021, which the Director of the Federal Register approved for incorporation by reference as of August 25, 2022 (87 FR 43403, July 21, 2022). This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in ADDRESSES. FAA’s Determination These products have been approved by the aviation authority of another country and are approved for operation in the United States. Pursuant to the FAA’s bilateral agreement with this State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI and service information described above. The FAA is issuing this NPRM after determining that the unsafe condition described previously is likely to exist or develop on other products of these same type designs. Proposed AD Requirements in This NPRM This proposed AD would retain all of the requirements of AD 2022–14–14, would add Model ASW–15B gliders to the applicability, and would provide the option of using the service material from AD 2022–14–14 or the updated service material. Differences Between This Proposed AD and the Service Information TN No. 29, Issue II, specifies the exchange of page 22A and page 27A of the Flight and Operations Manual for the Model ASW–15 and ASW–15B gliders, respectively, with a new version of those pages and then specifies documenting this change on page 3, Amendments, of the respective manual, and the MCAI, and this proposed AD do not. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 29 gliders of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Parts cost Inspect root ribs ................ 1 work-hour × $85 per hour = $85 ....... Not Applicable .. The FAA estimates the following costs to do any necessary replacements that would be required based on the Cost on U.S. operators Cost per product $85 per product per inspection cycle. results of the proposed inspection. The agency has no way of determining the $2,465 per inspection cycle. number of gliders that might need these replacements: lotter on DSK11XQN23PROD with PROPOSALS1 ON-CONDITION COSTS Action Labor cost Replace all four root ribs ............................. 8 work-hours × $85 per hour = $680 ............................................ 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 VerDate Sep<11>2014 17:22 Nov 09, 2022 Jkt 259001 Parts cost 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 PO 00000 Frm 00005 Fmt 4702 Sfmt 4702 $1,000 Cost per product $1,680 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 E:\FR\FM\10NOP1.SGM 10NOP1 Federal Register / Vol. 87, No. 217 / Thursday, November 10, 2022 / Proposed Rules (d) Subject Joint Aircraft System Component (JASC) Code 5712, Wing, Rib/Bulkhead. 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 that the 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

2022-14-14, which applies to all Alexander Schleicher GmbH & Co. 
Segelflugzeugbau Model ASW-15 gliders. AD 2022-14-14 requires 
repetitively inspecting the wing root ribs for cracks, looseness, and 
damage and replacing any root rib with a crack, a loose rib or lift pin 
bushing, or any damage. Since the FAA issued AD 2022-14-14, the 
European Union Aviation Safety Agency (EASA) superseded its mandatory 
continuing airworthiness information (MCAI) to add all Model ASW-15B 
gliders to the applicability. This proposed AD is prompted by MCAI 
originated by an aviation authority of another country to identify and 
correct an unsafe condition on an aviation product. This proposed AD 
would retain the requirements from AD 2022-14-14 of repetitively 
inspecting the wing root ribs for cracks, looseness, and damage and 
replacing any root rib with a crack, a loose rib or lift pin bushing, 
or any damage; and would add the Model ASW-15B gliders to the 
applicability. The FAA is proposing this AD to address the unsafe 
condition on these products.

the following paragraph, and other information as described in 14 CFR 
11.35, the FAA will post all comments received, without change, to 
regulations.gov, including any personal information you provide. The 
agency will also post a report summarizing each substantive verbal 
contact received about this NPRM.

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 Jim 
Rutherford, Aviation Safety Engineer, General Aviation & Rotorcraft 
Section, International Validation Branch, FAA, 901 Locust, Room 301, 
Kansas City, MO 64106. Any commentary that the FAA receives which is 
not specifically designated as CBI will be placed in the public docket 
for this rulemaking.

Background

    The FAA issued AD 2022-14-14, Amendment 39-22119 (87 FR 43403, July 
21, 2022), (AD 2022-14-14), for all serial-numbered Alexander 
Schleicher GmbH & Co. Segelflugzeugbau Model ASW-15 gliders. AD 2022-
14-14 was prompted by MCAI originated by EASA, which is the Technical 
Agent for the

[[Page 67838]]

Member States of the European Union. EASA issued EASA AD 2021-0187, 
dated August 9, 2021 (EASA AD 2021-0187), for all Alexander Schleicher 
GmbH & Co. Segelflugzeugbau Model ASW 15 gliders to correct an unsafe 
condition identified as wing root rib damage.
    AD 2022-14-14 requires repetitively inspecting the wing root ribs 
for cracks, looseness, and damage and replacing any root rib with a 
crack, a loose rib or lift pin bushing, or any damage. The FAA issued 
AD 2022-14-14 to detect and correct damaged root ribs.

Actions Since AD 2022-14-14 Was Issued

    Since the FAA issued AD 2022-14-14, Alexander Schleicher GmbH & Co. 
Segelflugzeugbau determined that Model ASW-15B gliders can also be 
affected by wing root rib damage. As a result, EASA superseded EASA AD 
2021-0187, and issued EASA AD 2022-0146, dated July 11, 2022 (referred 
to after this as ``the MCAI''). The MCAI states that wing root rib 
damage can also affect Model ASW-15B gliders and the Model ASW-15B as 
well as the ASW-15 gliders require repetitively inspecting the wing 
root ribs and replacing any damaged wing root ribs. The MCAI retains 
the requirements of EASA AD 2021-0187 and expands the applicability to 
include all Model ASW-15B gliders.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2022-1303.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Alexander Schleicher GmbH & Co. Segelflugzeugbau 
ASW 15 Technical Note No. 29, Issue II (TN No. 29, Issue II), dated May 
4, 2022. This service information specifies replacement of root ribs.
    This proposed AD would also require Alexander Schleicher GmbH & Co. 
Segelflugzeugbau ASW 15 Technical Note No. 29, dated June 28, 2021; 
Alexander Schleicher GmbH & Co. Segelflugzeugbau ASW 15 Repair 
instruction exchange of wing root ribs according to TN 29, dated June 
28, 2021; and Alexander Schleicher GmbH & Co. Segelflugzeugbau ASW 15 
Maintenance Instruction G, Issue 1, dated June 28, 2021, which the 
Director of the Federal Register approved for incorporation by 
reference as of August 25, 2022 (87 FR 43403, July 21, 2022).
    This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in ADDRESSES.

FAA's Determination

    These products have been approved by the aviation authority of 
another country and are approved for operation in the United States. 
Pursuant to the FAA's bilateral agreement with this State of Design 
Authority, it has notified the FAA of the unsafe condition described in 
the MCAI and service information described above. The FAA is issuing 
this NPRM after determining that the unsafe condition described 
previously is likely to exist or develop on other products of these 
same type designs.

Proposed AD Requirements in This NPRM

    This proposed AD would retain all of the requirements of AD 2022-
14-14, would add Model ASW-15B gliders to the applicability, and would 
provide the option of using the service material from AD 2022-14-14 or 
the updated service material.

Differences Between This Proposed AD and the Service Information

    TN No. 29, Issue II, specifies the exchange of page 22A and page 
27A of the Flight and Operations Manual for the Model ASW-15 and ASW-
15B gliders, respectively, with a new version of those pages and then 
specifies documenting this change on page 3, Amendments, of the 
respective manual, and the MCAI, and this proposed AD do not.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 29 gliders of U.S. registry.
    The FAA estimates the following costs to comply with this proposed 
AD:

                                                 Estimated Costs

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

    The FAA estimates the following costs to do any necessary 
replacements that would be required based on the results of the 
proposed inspection. The agency has no way of determining the number of 
gliders that might need these replacements:

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

[[Page 67839]]

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 that the 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.
