We are adopting a new airworthiness directive (AD) for certain Honeywell International Inc. (Honeywell) TPE331 model turboprop engines and TSE331-3U model turboshaft engines. This AD was prompted by the discovery of cracks in a 2nd stage compressor impeller during a routine shop visit. This AD requires removal of the 2nd stage compressor impeller. We are issuing this AD to prevent failure of the compressor impeller, uncontained part release, damage to the engine, and damage to the airplane.

Airworthiness Directives; Honeywell International Inc. Turboprop 
and Turboshaft Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Honeywell International Inc. (Honeywell) TPE331 model turboprop engines 
and TSE331-3U model turboshaft engines. This AD was prompted by the 
discovery of cracks in a 2nd stage compressor impeller during a routine 
shop visit. This AD requires removal of the 2nd stage compressor 
impeller. We are issuing this AD to prevent failure of the compressor 
impeller, uncontained part release, damage to the engine, and damage to 
the airplane.

DATES: This AD is effective November 4, 2016.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain Honeywell TPE331 
model turboprop engines and TSE331-3U model turboshaft engines. The 
NPRM published in the Federal Register on March 15, 2016 (81 FR 13764) 
(``the NPRM''). The NPRM was prompted by the discovery of cracks in a 
2nd stage compressor impeller during a routine shop visit. The NPRM 
proposed to require removal of the 2nd stage compressor impeller. We 
are issuing this AD to prevent failure of the compressor impeller, 
uncontained part release, damage to the engine, and damage to the 
airplane.

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 Change Compliance

    Bearskin Airlines and Turbine Standard, LTD requested that the 
compliance time interval be changed because many TPE331 engine 
operators are on a Continuous Airworthiness Maintenance (CAM) program. 
This program does not require impeller inspections per the overhaul 
manual and the impeller is not considered as ``overhauled''. AD 
compliance under CAM may be interpreted as being within 200 cycles or 
30 to 45 days.
    Other commenters requested that the compliance time be changed to a 
less aggressive time interval appropriate to the unsafe condition. Many 
high-usage operators have suspect impellers that currently exceed 7,000 
cycles since the last compressor inspection.
    We agree. We changed compliance interval in paragraph (e)(1) of 
this AD.

Request To Allow Other Inspection Facilities To Return Impellers to 
Service

    Turbine Standard, LTD requested that this AD allow other inspection 
facilities to return impellers to service. There are many inspection 
facilities that are capable of inspecting the 2nd stage compressor 
impeller.
    We partially agree. We agree that many inspection facilities are 
capable of performing a focused inspection of the 2nd stage compressor 
impeller. We disagree with allowing other inspection and regrinding 
facilities to return impellers to service. This AD does not address 
inspection or regrinding of the curvic area of the 2nd stage compressor 
impeller. Regrinding of the curvic area of the 2nd stage compressor 
impeller involves machining of a critical rotating part, which must be 
approved by the FAA. We did not change this AD.

Request To Change Costs of Compliance

    Honeywell; Perimeter Aviation, LP; and Intercontinental Jet Service 
Corp. requested that the costs of compliance be changed because the 
NPRM is not representative of the impeller's replacement costs. 
Honeywell quotes the cost of a new 2nd stage compressor impeller at 
$11,922.50.
    We partially agree. We agree with the comment because the costs 
were not clearly defined. We disagree with the comment because 
replacement costs are based on pro-rated costs that are estimated at 
50% of new parts costs. Since issuing the NPRM, the FAA estimated that 
30% of impellers will be scrapped; therefore, we changed the costs of 
compliance accordingly.

Request To Include Service Information

    The European Aviation Safety Agency, Honeywell, and Candler & 
Associates, Inc. requested that service information be included in this 
AD. Having the service information available would aid in understanding 
any differences between this AD and the service information.
    We agree. We added Honeywell Service Bulletin (SB) TPE331-72-2208, 
dated July 29, 2014, as related information in this AD.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the changes described previously.
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Related Service Information

    We reviewed Honeywell SB TPE331-72-2208, dated July 29, 2014. The 
SB describes procedures for replacing the 2nd stage compressor 
impeller.

Costs of Compliance

    We estimate that this AD will affect 4,000 engines installed on 
airplanes of U.S. registry. We estimate that it will take 2 hours per 
engine to comply with this AD. The average labor rate is $85 per hour. 
We also estimate that required parts will cost about $4,404.50 per 
engine. Based on these figures, we estimate the total cost of this AD 
on U.S. operators to be $18,298,000.

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.

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) 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 to the extent 
that it justifies making a regulatory distinction, 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.
