SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain P&WC PT6E–67XP model turboprop engines with serial number HP0194 and earlier. The NPRM published in the Federal Register on November 18, 2022 (87 FR 69218). The NPRM was prompted by Transport Canada AD CF–2022–26–E, dated May 12, 2022 (Transport Canada AD CF– 2022–26–E) (referred to after this as the MCAI). The MCAI states that there have been reports of multiple incidents in which engines were unable to achieve the required power (torque) during high power applications. A manufacturer investigation found that contamination from the glass beads used in the manufacturing process during the gas generator casing (GGC) production caused internal leaks in the BOVs, preventing the BOVs from fully closing at high power settings. In the NPRM, the FAA proposed to require replacement of the compressor PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 BOV assembly, replacement of the BOV orifice feed air tube assembly, and installation of a redesigned P3 probe snorkel, as specified in Transport Canada AD CF–2022–26. The FAA is issuing this AD to address the unsafe condition on these products. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2022–1477. 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 This product has been approved by the aviation authority of another country and is 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 referenced above. 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 this product. 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. Related Service Information Under 1 CFR Part 51 The FAA reviewed Transport Canada AD CF–2022–26, which specifies procedures for the replacement of the compressor BOV assembly, replacement of the BOV orifice feed air tube assembly, and installation of a redesigned P3 probe snorkel. 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 ADDRESSES. Costs of Compliance The FAA estimates that this AD affects 100 engines installed on airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: E:\FR\FM\14FER1.SGM 14FER1 9388 Federal Register / Vol. 88, No. 30 / Tuesday, February 14, 2023 / Rules and Regulations ESTIMATED COSTS Action Labor cost Replace compressor BOV assembly ...................................... Replace BOV orifice feed air tube assembly with P3 probe snorkel and BOV orifice feed air tube assembly. Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety.

SUPPLEMENTARY INFORMATION: 

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to certain P&WC PT6E-67XP 
model turboprop engines with serial number HP0194 and earlier. The NPRM 
published in the Federal Register on November 18, 2022 (87 FR 69218). 
The NPRM was prompted by Transport Canada AD CF-2022-26-E, dated May 
12, 2022 (Transport Canada AD CF-2022-26-E) (referred to after this as 
the MCAI). The MCAI states that there have been reports of multiple 
incidents in which engines were unable to achieve the required power 
(torque) during high power applications. A manufacturer investigation 
found that contamination from the glass beads used in the manufacturing 
process during the gas generator casing (GGC) production caused 
internal leaks in the BOVs, preventing the BOVs from fully closing at 
high power settings.
    In the NPRM, the FAA proposed to require replacement of the 
compressor BOV assembly, replacement of the BOV orifice feed air tube 
assembly, and installation of a redesigned P3 probe snorkel, as 
specified in Transport Canada AD CF-2022-26. The FAA is issuing this AD 
to address the unsafe condition on these products.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2022-1477.

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

    This product has been approved by the aviation authority of another 
country and is 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 
referenced above. 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 this product. 
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.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Transport Canada AD CF-2022-26, which specifies 
procedures for the replacement of the compressor BOV assembly, 
replacement of the BOV orifice feed air tube assembly, and installation

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

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.

(d) Subject

(e) Unsafe Condition

    This AD was prompted by reports of multiple incidents in which 
engines were unable to achieve the required power (torque) during 
high power applications due to internal leaks in the bleed-off

this AD to prevent internal leaks in the BOVs, and to prevent the 
failure of the engine to achieve the required power (torque) during 
high power applications. The unsafe condition, if not addressed, 
could result in loss of thrust control and loss of the airplane.
