SUPPLEMENTARY INFORMATION: Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Continental Aerospace E:\FR\FM\17AUR1.SGM 17AUR1 49955 Federal Register / Vol. 85, No. 159 / Monday, August 17, 2020 / Rules and Regulations Technologies, Inc. model GTSIO–520–C, GTSIO–520–D, GTSIO–520–H, GTSIO– 520–K, GTSIO–520–L, GTSIO–520–M, GTSIO–520–N, IO–550–G, IO–550–N, IO–550–P, IO–550–R, IOF–550–N, IOF– 550–P, IOF–550–R, TSIO–520–BE, TSIO–550–A, TSIO–550–B, TSIO–550– C, TSIO–550–E, TSIO–550–G, TSIO– 550–K, TSIO–550–N, TSIOF–550–D, TSIOF–550–J, TSIOF–550–K, and TSIOF–550–P reciprocating AvGas engines with a certain cross-flow cylinder assembly installed. The NPRM published in the Federal Register on April 17, 2020 (85 FR 21336). The NPRM was prompted by reports of inflight engine failures due to fractured cross-flow cylinder assemblies. The NPRM proposed to require visual inspection of the cross-flow cylinder assembly and, depending on the results of the inspection, modification or replacement of the cross-flow cylinder assembly. The FAA is issuing this AD to address the unsafe condition on these products. Comments The FAA gave the public the opportunity to participate in developing this final rule. The following presents the comment received on the NPRM and the FAA’s response to the comment. Request To Revise Compliance An individual commenter requested that the FAA revise the beginning of paragraph (g)(2), Required Actions, of this AD from ‘‘If the engine has 500 engine operating hours or greater on the effective date of this AD . . .’’ to ‘‘If the engine has 500 engine operating hours or greater after the effective date of this AD . . .’’ The commenter reasoned that the AD, as written, could allow aircraft operated exclusively under 14 CFR part 91 with fewer than 500 engine operating hours on the effective date of the AD to fly for an unlimited number of engine operating hours until the next annual inspection, as the 100-hour inspection is not required for part 91 operations. The FAA partially agrees. The FAA agrees that part 91 operators may fly their aircraft for an unlimited number of engine operating hours between annual inspections. Historically, the typical part 91 operator flies fewer than 100 engine operating hours per year, however. The FAA has reviewed the specific scenario outlined by the commenter and evaluated it against the associated risk assessment. The FAA disagrees with the commenter’s request to revise the language in paragraph (g)(2), Required Actions, of this AD. Any aircraft with an affected engine, regardless of how they are being operated, must comply within the compliance times contained in the Required Actions section of this AD. All affected engines with fewer than 500 engine operating hours on the effective date of this AD must perform the visual inspection of the cross-flow cylinder assembly at the next 100-hour inspection or the next annual inspection, depending on aircraft operation. All affected engines with 500 engine operating hours or greater on the effective date of this AD must perform the visual inspection of the cross-flow cylinder assembly at the next maintenance event, not to exceed 50 engine operating hours, after the effective date of the AD. The FAA did not change this AD. Conclusion The FAA reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting this final rule as proposed except for minor editorial changes. The FAA has determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. Related Service Information Under 1 CFR Part 51 The FAA reviewed Continental Aerospace Technologies, Inc. Mandatory Service Bulletin (MSB) 18– 08, Revision B, dated January 13, 2020. The MSB describes procedures for inspection, modification, or replacement of the cross-flow cylinder assembly. 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 the ADDRESSES section. Costs of Compliance The FAA estimates that this AD affects 4,000 engines installed on airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: ESTIMATED COSTS Action Labor cost Visual inspection of the cross-flow cylinder assembly. 2 work-hours × $85 per hour = $170 ............. The FAA estimates the following costs to do any necessary modification or replacement of the cross-flow Cost per product Parts cost cylinder assembly that would be required based on the results of the visual inspection. The FAA has no way $0 Cost on U.S. operators $170 $680,000 of determining the number of cross-flow cylinder assemblies that might need this modification or replacement: ON-CONDITION COSTS Action Labor cost Modify the cross-flow cylinder assembly ...................... Replace the cross-flow cylinder assembly ................... 1 work-hour × $85 per hour = $85 ............................... 11.5 work-hours × $85 per hour = $977.50 ................. According to the manufacturer, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. The VerDate Sep<11>2014 16:18 Aug 14, 2020 Jkt 250001 FAA does not control warranty coverage for affected individuals. As a result, the FAA has included all costs in our cost estimate.

Subtitle I, E:\FR\FM\17AUR1.SGM 17AUR1 49956 Federal Register / Vol. 85, No. 159 / Monday, August 17, 2020 / Rules and Regulations 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) 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.

SUPPLEMENTARY INFORMATION: Discussion The FAA issued an NPRM to amend 14 CFR part 39 by adding an AD that would apply to Viking Air Limited Models DHC–2 Mk. I and DHC–2 Mk. III airplanes. The NPRM published in the Federal Register on February 11, 2019 (84 FR 3131). The NPRM proposed to correct an unsafe condition for the specified products and was based on AD Number CF–2018–10, dated April 18, 2018 (referred to after this as ‘‘the MCAI’’), issued by Transport Canada, which is the aviation authority for Canada. The MCAI states: Cracks have been reported on the Forward and Aft float strut wire pull fittings on DHC– 2 Mk. I aeroplanes equipped with the 5600 lb gross weight increase kit installed in accordance with STC SA92–63 or SA00299NY and on DHC–2 Mk. III aeroplanes equipped with the 6000 lb gross weight increase kit installed in accordance with STC SA91–18 or SA945NE. An investigation found that the forward and aft wire pull fittings (P/N VALTBS1245–1/–2 and P/N VALTBS1244–1, respectively) are prone to stress corrosion cracking at low cycles/hours. Failure of these wire pull fittings will reduce the strength of the float undercarriage below the required structural capability and could result in a failure of the undercarriage causing the aeroplane to tip over and be submerged. Therefore this [Transport Canada] AD requires that the forward and aft wire pull fittings be replaced with P/N VALTBS1245– 3/–4 and P/N VALTBS1244–3/–4 (LH/RH) fittings respectively. These fittings are geometrically similar to the legacy fittings and are made of a different aluminum alloy that is less susceptible to stress corrosion cracking. In addition to replacing the fittings, it is necessary to implement a recurring visual inspection of the fittings to assure continuing airworthiness. The MCAI can be found in the AD docket on the internet at: https:// www.regulations.gov/docket?D=FAA2019-0045. Comments The FAA gave the public the opportunity to participate in developing this AD. The following presents the comment received on the NPRM and the FAA’s response. Request To Remove the Repetitive Inspection Christopher Campbell requested the FAA remove the 110-hour repetitive inspection requirement. The commenter stated the unsafe condition is eliminated by the requirement to E:\FR\FM\17AUR1.SGM 17AUR1

SUPPLEMENTARY INFORMATION:

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to all Continental 
Aerospace

[[Page 49955]]

Technologies, Inc. model GTSIO-520-C, GTSIO-520-D, GTSIO-520-H, GTSIO-
520-K, GTSIO-520-L, GTSIO-520-M, GTSIO-520-N, IO-550-G, IO-550-N, IO-
550-P, IO-550-R, IOF-550-N, IOF-550-P, IOF-550-R, TSIO-520-BE, TSIO-
550-A, TSIO-550-B, TSIO-550-C, TSIO-550-E, TSIO-550-G, TSIO-550-K, 
TSIO-550-N, TSIOF-550-D, TSIOF-550-J, TSIOF-550-K, and TSIOF-550-P 
reciprocating AvGas engines with a certain cross-flow cylinder assembly 
installed. The NPRM published in the Federal Register on April 17, 2020 
(85 FR 21336). The NPRM was prompted by reports of in-flight engine 
failures due to fractured cross-flow cylinder assemblies. The NPRM 
proposed to require visual inspection of the cross-flow cylinder 
assembly and, depending on the results of the inspection, modification 
or replacement of the cross-flow cylinder assembly. The FAA is issuing 
this AD to address the unsafe condition on these products.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The following presents the comment received 
on the NPRM and the FAA's response to the comment.

Request To Revise Compliance

    An individual commenter requested that the FAA revise the beginning 
of paragraph (g)(2), Required Actions, of this AD from ``If the engine 
has 500 engine operating hours or greater on the effective date of this 
AD . . .'' to ``If the engine has 500 engine operating hours or greater 
after the effective date of this AD . . .'' The commenter reasoned that 
the AD, as written, could allow aircraft operated exclusively under 14 
CFR part 91 with fewer than 500 engine operating hours on the effective 
date of the AD to fly for an unlimited number of engine operating hours 
until the next annual inspection, as the 100-hour inspection is not 
required for part 91 operations.
    The FAA partially agrees. The FAA agrees that part 91 operators may 
fly their aircraft for an unlimited number of engine operating hours 
between annual inspections. Historically, the typical part 91 operator 
flies fewer than 100 engine operating hours per year, however. The FAA 
has reviewed the specific scenario outlined by the commenter and 
evaluated it against the associated risk assessment. The FAA disagrees 
with the commenter's request to revise the language in paragraph 
(g)(2), Required Actions, of this AD. Any aircraft with an affected 
engine, regardless of how they are being operated, must comply within 
the compliance times contained in the Required Actions section of this 
AD. All affected engines with fewer than 500 engine operating hours on 
the effective date of this AD must perform the visual inspection of the 
cross-flow cylinder assembly at the next 100-hour inspection or the 
next annual inspection, depending on aircraft operation. All affected 
engines with 500 engine operating hours or greater on the effective 
date of this AD must perform the visual inspection of the cross-flow 
cylinder assembly at the next maintenance event, not to exceed 50 
engine operating hours, after the effective date of the AD. The FAA did 
not change this AD.

Conclusion

    The FAA reviewed the relevant data, considered the comment 
received, and determined that air safety and the public interest 
require adopting this final rule as proposed except for minor editorial 
changes. The FAA has determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Continental Aerospace Technologies, Inc. Mandatory 
Service Bulletin (MSB) 18-08, Revision B, dated January 13, 2020. The 
MSB describes procedures for inspection, modification, or replacement 
of the cross-flow cylinder assembly. 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 
the ADDRESSES section.

Costs of Compliance

    The FAA estimates that this AD affects 4,000 engines installed on 
airplanes of U.S. registry.
    The FAA estimates the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
                Action                         Labor cost           Parts cost        product        operators
----------------------------------------------------------------------------------------------------------------
Visual inspection of the cross-flow     2 work-hours x $85 per                $0            $170        $680,000
 cylinder assembly.                      hour = $170.
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary 
modification or replacement of the cross-flow cylinder assembly that 
would be required based on the results of the visual inspection. The 
FAA has no way of determining the number of cross-flow cylinder 
assemblies that might need this modification or replacement:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                     Cost per
                    Action                                 Labor cost               Parts cost        product
----------------------------------------------------------------------------------------------------------------
Modify the cross-flow cylinder assembly.......  1 work-hour x $85 per hour = $85              $0             $85
Replace the cross-flow cylinder assembly......  11.5 work-hours x $85 per hour =        1,933.28        2,910.78
                                                 $977.50.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. The FAA does not control warranty coverage for affected 
individuals. As a result, the FAA has included all costs in our cost 
estimate.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I,

[[Page 49956]]

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) 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.
