SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 88–12–10, Amendment 39–5910 (53 FR 19766, May 31, 1988), (‘‘AD 88–12–10’’). AD 88–12–10 applied to Honeywell TPE331–10, –10R, –10U, –10UA, –10UF, –10UG, –10UGR, –10UR, and –11U turboprop engines equipped with 2nd stage turbine rotors, part numbers 3102106–1, –6, and –8, installed. The NPRM published in the Federal Register on June 20, 2018 (83 FR 28550). The NPRM was prompted by a report that a TPE331–11U engine installed on an M7 Aerospace LP SA227 airplane experienced an uncontained rotor separation. In addition, cracks were discovered through ECI in the bore of the second stage turbine rotor assembly after publication of AD 88–12–10. The NPRM proposed to remove certain second stage turbine rotors from service at a reduced life limit. We are issuing this AD to address the unsafe condition on these products. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM and the FAA’s response to each comment. Request To Revise Compliance Times Honeywell requested that we remove from the NPRM the statement that the FAA finds that allowing an additional 100 cycles-in-service before their removal provides a sufficient level of safety for applicable second stage turbine rotors that have been in service for 30 years after the publication of AD 88–12–10. Honeywell indicated it believes that most of the IN100 rotors have been replaced at around 3,500 cycles during hot section inspection. Honeywell noted that the rotors would not make it to the next hot section inspection with a life of 4,800 cycles. Honeywell noted that there is a not a lot of field experience for IN100 rotors beyond 3,500 cycles. Honeywell commented that the removal schedule in the Honeywell service bulletin needs to remain the same (within 100 cycles-in-service for 3,301 to 4,000 cycles since new (CSN) rotors and within 50 cycles-in-service for 4,001 to 4,800 CSN rotors) since the event rotor failed at around 4,100 cycles. Additionally, Honeywell has also found rotors through eddy current inspection that had long cracks at around 4,300 cycles. We disagree. We would normally only require removal of parts within 50 cycles-in-service after the effective date of an AD when the risk justifies immediate action. The FAA assessed the risk of the affected rotors based on service experience and IN100 rotor propagation life of cracked and failed rotors. We found that the additional cycles in service allowed by this AD before the removal of the second stage turbine rotors provides an acceptable level of safety. We did not change this AD. Conclusion We reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting this AD as proposed. Related Service Information We reviewed Honeywell Service Bulletin (SB) TPE331–72–A2319, Revision 0, dated April 25, 2018, and TPE331–72–A2310, Revision 0, dated January 26, 2018. These SBs describe procedures for replacement of the second stage turbine rotor assembly installed on TPE331–8, –10, –10N, –10R, –10U, –10UA, –10UF, –10UG, –10UGR, –10UR, and –11U model engines. Costs of Compliance We estimate that this AD affects 100 engines installed on airplanes of U.S. registry. We estimate that 20 commercial engines and 80 general aviation engines will need this turbine rotor replacement to comply with this AD: ESTIMATED COSTS Action Labor cost Scheduled rotor replacement .......................... Unscheduled rotor replacement ...................... 1 work-hour × $85 per hour = $85 ................. 41 work-hours × $85 per hour = $3,485 ........ 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. VerDate Sep<11>2014 16:30 Nov 02, 2018 Jkt 247001 Parts cost We are 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 PO 00000 Frm 00010 Fmt 4700 Sfmt 4700 $7,500 7,500 Cost per product $7,585 10,985 Cost on U.S. operators $379,250 549,250 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. This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, E:\FR\FM\05NOR1.SGM 05NOR1 Federal Register / Vol. 83, No. 214 / Monday, November 5, 2018 / Rules and Regulations as authorized by FAA Order 8000.51C.

SUPPLEMENTARY INFORMATION: of the European Community, issued EASA AD No. 2018–0030, dated January 31, 2018 (referred to after this as ‘‘the MCAI’’). The MCAI states that: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 98–16–03, Amendment 39–10677 (63 FR 40359, July 29, 1998) (‘‘AD 98–16–03’’). The NPRM was published in the Federal Register on May 9, 2018 (83 FR 21199), and proposed to correct an unsafe condition for SOCATA Model TB 9, Model TB 10, and Model TB 200 airplanes. We based the NPRM on MCAI originated by an aviation authority of another country. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States Request for an Explanation of Compliance Time Daher requested that we explain why the compliance times in the NPRM are presented in landings and do not match the compliance times in the EASA AD, which uses both hours time-in-service (TIS) and number of landings. The NPRM retained the compliance times from AD 98–16–03, which were based in landings instead of hours TIS. The NPRM also retained the formula for converting hours TIS to landings from AD 98–16–03 for airplanes with an unknown number of landings. Because we also retained the effective date of AD PO 00000 Frm 00012 Fmt 4700 Sfmt 4700 During a scheduled maintenance inspection, cracks were found on the wing front attachments of a TB 10 aeroplane. This condition, if not detected and corrected, could affect the structural integrity of the aeroplane. Prompted by these findings, SOCATA issued SB 10–081–57 to provide inspection and modification instructions, and DGAC France issued AD 94–264(A), later revised, to require repetitive inspections of wing front attachments of TB 9 and TB 10 aeroplanes (all MSN up to 822 inclusive, with some excluded). That [DGAC France] AD also required installation of reinforcement kits, applied as repair (if cracks were found) or as modification (if no cracks were found), of the wing front attachments, on both wing and fuselage sides, and repetitive replacement of those reinforcements afterwards. Since DGAC France AD 94–264(A) R1 was issued, cracks have been found on wing front attachments, on the wing side, on TB10 aeroplanes to which the AD did not apply, i.e. which were not subject to repetitive inspections as required by that [DGAC France] AD. Consequently, SOCATA revised SB 10–081–57 (now at revision (rev) 3), extending the Applicability to all TB 10 aeroplanes, as well as to TB 200 aeroplanes, and improving the repair solution of the wing front attachment on wing side. For the reason described above, this [EASA] AD retains the requirements of DGAC France AD 94–264(A) R1, which is superseded, expands the Applicability to all MSN for TB 9 and TB 10 aeroplanes and includes TB 200 aeroplanes, and requires an improved repair solution of the wing front attachment on wing side. The MCAI can be found in the AD docket on the internet at: https:// www.regulations.gov/document?D= FAA-2018-0326-0003. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comment received on the proposal and the FAA’s response to the comment.

[Docket No. FAA-2018-0216; Product Identifier 1988-ANE-18-AD; Amendment 
39-19474; AD 2018-22-01]
RIN 2120-AA64


Airworthiness Directives; Honeywell International Inc. Turboprop 
Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 88-12-10 for 
certain Honeywell International Inc. (Honeywell) TPE331 turboprop 
engines. AD 88-12-10 required reducing the life limit for certain 
second stage turbine rotors. This AD requires removing certain second 
stage turbine rotors from service at a reduced life limit. This AD was 
prompted by report that a TPE331-11U engine experienced an uncontained 
rotor separation. In addition, cracks were discovered through eddy 
current inspection (ECI) in the bore of the second stage turbine rotor 
assembly after publication of AD 88-12-10. We are issuing this AD to 
address the unsafe condition on these products.

DATES: This AD is effective December 10, 2018.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 88-12-10, Amendment 39-5910 (53 FR 19766, May 
31, 1988), (``AD 88-12-10''). AD 88-12-10 applied to Honeywell TPE331-
10, -10R, -10U, -10UA, -10UF, -10UG, -10UGR, -10UR, and -11U turboprop 
engines equipped with 2nd stage turbine rotors, part numbers 3102106-1, 
-6, and -8, installed. The NPRM published in the Federal Register on 
June 20, 2018 (83 FR 28550). The NPRM was prompted by a report that a 
TPE331-11U engine installed on an M7 Aerospace LP SA227 airplane 
experienced an uncontained rotor separation. In addition, cracks were 
discovered through ECI in the bore of the second stage turbine rotor 
assembly after publication of AD 88-12-10. The NPRM proposed to remove 
certain second stage turbine rotors from service at a reduced life 
limit. We are issuing this AD to address the unsafe condition on these 
products.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM and 
the FAA's response to each comment.

Request To Revise Compliance Times

    Honeywell requested that we remove from the NPRM the statement that 
the FAA finds that allowing an additional 100 cycles-in-service before 
their removal provides a sufficient level of safety for applicable 
second stage turbine rotors that have been in service for 30 years 
after the publication of AD 88-12-10. Honeywell indicated it believes 
that most of the IN100 rotors have been replaced at around 3,500 cycles 
during hot section inspection. Honeywell noted that the rotors would 
not make it to the next hot section inspection with a life of 4,800 
cycles. Honeywell noted that there is a not a lot of field experience 
for IN100 rotors beyond 3,500 cycles.
    Honeywell commented that the removal schedule in the Honeywell 
service bulletin needs to remain the same (within 100 cycles-in-service 
for 3,301 to 4,000 cycles since new (CSN) rotors and within 50 cycles-
in-service for 4,001 to 4,800 CSN rotors) since the event rotor failed 
at around 4,100 cycles. Additionally, Honeywell has also found rotors 
through eddy current inspection that had long cracks at around 4,300 
cycles.
    We disagree. We would normally only require removal of parts within 
50 cycles-in-service after the effective date of an AD when the risk 
justifies immediate action. The FAA assessed the risk of the affected 
rotors based on service experience and IN100 rotor propagation life of 
cracked and failed rotors. We found that the additional cycles in 
service allowed by this AD before the removal of the second stage 
turbine rotors provides an acceptable level of safety. We did not 
change this AD.

Conclusion

    We reviewed the relevant data, considered the comment received, and 
determined that air safety and the public interest require adopting 
this AD as proposed.

Related Service Information

    We reviewed Honeywell Service Bulletin (SB) TPE331-72-A2319, 
Revision 0, dated April 25, 2018, and TPE331-72-A2310, Revision 0, 
dated January 26, 2018. These SBs describe procedures for replacement 
of the second stage turbine rotor assembly installed on TPE331-8, -10, 
-10N, -10R, -10U, -10UA, -10UF, -10UG, -10UGR, -10UR, and -11U model 
engines.

Costs of Compliance

    We estimate that this AD affects 100 engines installed on airplanes 
of U.S. registry.
    We estimate that 20 commercial engines and 80 general aviation 
engines will need this turbine rotor replacement to comply with this 
AD:

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.
    We are 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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service,

[[Page 55257]]

as authorized by FAA Order 8000.51C. In accordance with that order, 
issuance of ADs is normally a function of the Compliance and 
Airworthiness Division, but during this transition period, the 
Executive Director has delegated the authority to issue ADs applicable 
to engines, propellers, and associated appliances to the Manager, 
Engine and Propeller Standards Branch, Policy and Innovation Division.

Regulatory Findings

    We have 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) Is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) 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.
