We propose to supersede Airworthiness Directive (AD) 88-12-10, which applies to certain Honeywell International Inc. (Honeywell) TPE331 turboprop engines. AD 88-12-10 requires reducing the life limit for certain second stage turbine rotors. Since we issued AD 88-12-10, we received a 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. This proposed AD would require removing certain second stage turbine rotors from service at a reduced life limit. We are proposing this AD to address the unsafe condition on these products.

Airworthiness Directives; Honeywell International Inc. Turboprop 
Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 88-12-10, 
which applies to certain Honeywell International Inc. (Honeywell) 
TPE331 turboprop engines. AD 88-12-10 requires reducing the life limit 
for certain second stage turbine rotors. Since we issued AD 88-12-10, 
we received a 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. This proposed 
AD would require removing certain second stage turbine rotors from 
service at a reduced life limit. We are proposing this AD to address 
the unsafe condition on these products.

Discussion

    We issued AD 88-12-10, Amendment 39-5910 (53 FR 19766, May 31, 
1988), (``AD 88-12-10''), for certain Honeywell TPE331 turboprop 
engines. AD 88-12-10 requires reducing the life limit for certain 
second stage turbine rotors. AD 88-12-10 resulted from the failure of a 
second stage turbine rotor due to crack growth from a bore initiation 
site induced by low cycle fatigue. We issued AD 88-12-10 to prevent 
failure of the second stage turbine rotor, leading to uncontained 
failure of the second stage turbine rotor.

Actions Since AD 88-12-10 Was Issued

    Since we issued AD 88-12-10, a TPE331-11U engine installed on an M7 
Aerospace LP SA227 airplane experienced an uncontained tri-hub rotor 
separation during climb on April 7, 2015. One of the three fragments 
from the second stage turbine rotor assembly, part number 3102106-6, 
came to rest inside the fuselage wall of the twin-engine airplane. In 
addition, second stage turbine rotor assembly cracks in the bore were 
discovered by ECI after publication of AD 88-12-10. This evidence 
supports higher stresses than originally calculated and supports the 
inability of the normal rotor inspection method, fluorescent penetrant 
inspection, to detect small cracks in the bore. In addition, we are 
adding the TPE331-8 and -10N model engines to the applicability of this 
AD because the design and material of its second stage turbine rotor 
are similar to those in the TPE331-10, -10R, -10U, -10UA, -10UF, -10UG, 
-10UGR, -10UR, and -11U model engines.

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.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would retain certain requirements of AD 88-12-10. 
This proposed AD would require removing certain second stage turbine 
rotors from service at a reduced life limit.

Differences Between This Proposed AD and the Service Information

    This NPRM proposes to allow certain rotors more time in service 
before their removal than is allowed by Honeywell SBs TPE331-72-A2310, 
Revision 0, dated January 26, 2018, and TPE331-72-A2319, Revision 0, 
dated April 25, 2018. 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. In addition, 
the SB includes a calendar deadline of 5 years for removal of the 
applicable second stage turbine rotors that have exceeded their life-
limit of 3,000 cycles. The FAA is instead proposing a requirement to 
remove applicable rotors at the next access and prohibiting the 
installation of applicable rotors. We find that the calendar deadline 
is inconsistent with our compliance requirements.

Costs of Compliance

    We estimate that this proposed 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 
proposed 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, 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 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,

[[Page 28552]]

    (2) Is not a ``significant rule'' under the 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.
