Discussion

    We have received reports of three accidents involving combustion 
chamber case assembly ruptures. Investigations have shown numerous 
cracked combustion chamber case assemblies resulting from high stresses 
in the as-designed weld joints and contributing factors due to repair 
weld quality, poor maintenance and inspection practices, and cycles-in-
service. From 1979 to 2016, twenty-four of these cracked combustion 
chamber case assemblies have propagated to rupture. This condition, if 
not corrected, could result in failure of the combustion chamber case 
assembly, in-flight shutdown, and reduced control of the airplane.

Related Service Information Under 1 CFR Part 51

    We reviewed Honeywell Service Bulletin (SB) TPE331-72-2178, 
Revision 0, dated May 3, 2011. The SB describes procedures for 
inspection and removal of the affected combustion chamber case 
assemblies. 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.

Other Related Service Information

    Honeywell has also issued SBs TPE331-72-2228, Revision 0, dated 
June 12, 2014; TPE331-72-2230, Revision 0, dated June 19, 2014; TPE331-
72-2218, Revision 1, dated July 13, 2016; TPE331-72-2244, Revision 1, 
dated July 20, 2016; TPE331-72-2235, Revision 1, dated July 21, 2016; 
TPE331-72-2281, Revision 0, dated July 22, 2016; TPE331-72-2294, 
Revision 0, dated December 22, 2016; and TSE331-72-2245, Revision 0, 
dated November 11, 2016. These SBs provide guidance on replacement of 
the affected combustion chamber case assemblies.

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.

[[Page 18403]]

Proposed AD Requirements

    This proposed AD would require inspection, replacement of the 
affected combustion chamber case assemblies, and removal of affected 
assemblies on certain TPE331 turboprop engines.

Differences Between This Proposed AD and the Service Information

    This AD proposes inspection and replacement of high-stressed 
combustion chamber case assemblies and those chamber case assemblies 
found cracked at scheduled routine inspections. Honeywell SBs TPE331-
72-2228, Revision 0, dated June 12, 2014; TPE331-72-2230, Revision 0, 
dated June 19, 2014; TPE331-72-2218, Revision 1, dated July 13, 2016; 
TPE331-72-2244, Revision 1, dated July 20, 2016; TPE331-72-2235, 
Revision 1, dated July 21, 2016; TPE331-72-2281, Revision 0, dated July 
22, 2016; TPE331-72-2294, Revision 0, dated December 22, 2016; and 
TSE331-72-2245, Revision 0, dated November 11, 2016, recommend the 
removal and replacement of the combustion chamber case assembly at next 
removal from the engine, but no later than March 31, 2021 or December 
31, 2021, depending on the respective engine.

Costs of Compliance

    We estimate that this proposed AD affects 5,644 engines installed 
on airplanes of U.S. registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------

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

    We estimate the following costs to do any necessary replacements 
that would be required based on the results of the proposed inspection. 
We estimate that 158 engines will need this replacement during the 
first year of inspection.

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

    We 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 this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (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 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.
