We will post all comments we receive, without change, to http:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this NPRM. Discussion We propose to adopt an AD for certain GE GE90–76B, GE90–85B, GE90–90B, GE90–94B, GE90–110B1, and GE90– 115B turbofan engines with a main heat exchanger, part number (P/N) 1838M88P11 or 1838M88P13. This proposed AD is prompted by a report of an airplane fire caused by a failed main heat exchanger. The incident investigation determined the cause to be an internal main heat exchanger tube separation, which resulted in leakage of fuel into the oil system, causing oil sump flooding that overwhelmed the scavenge and venting system. This condition, if not corrected, could result in failure of a main heat exchanger, which could cause an engine fire. To correct this unsafe condition, we propose to require replacing the main heat exchanger with a part not affected by this proposed AD or with a part that is repaired in accordance with the manufacturer’s service information. Related Service Information Under 1 CFR Part 51 We reviewed GE Service Bulletin (SB) GE90–100 SB 79–0034, Revision 03, dated August 5, 2016, and SB GE90 SB 79–0058, Revision 02, dated August 5, 2016. This service information describes procedures to replace and repair a main heat exchanger. These documents are distinct since they apply to different engine models. 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. 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 require replacing the affected main heat exchangers with a part eligible for installation. Costs of Compliance We estimate that this proposed AD affects 185 engines installed on airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Replace main heat exchanger ........................ 5 work-hours × $85 per hour = $425 ............. $7,000 $7,425 $1,373,625 asabaliauskas on DSK3SPTVN1PROD with PROPOSALS Authority for This Rulemaking Regulatory Findings 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. 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.

Discussion

    We propose to adopt an AD for certain GE GE90-76B, GE90-85B, GE90-
90B, GE90-94B, GE90-110B1, and GE90-115B turbofan engines with a main 
heat exchanger, part number (P/N) 1838M88P11 or 1838M88P13.
    This proposed AD is prompted by a report of an airplane fire caused 
by a failed main heat exchanger. The incident investigation determined 
the cause to be an internal main heat exchanger tube separation, which 
resulted in leakage of fuel into the oil system, causing oil sump 
flooding that overwhelmed the scavenge and venting system. This 
condition, if not corrected, could result in failure of a main heat 
exchanger, which could cause an engine fire. To correct this unsafe 
condition, we propose to require replacing the main heat exchanger with 
a part not affected by this proposed AD or with a part that is repaired 
in accordance with the manufacturer's service information.

Related Service Information Under 1 CFR Part 51

    We reviewed GE Service Bulletin (SB) GE90-100 SB 79-0034, Revision 
03, dated August 5, 2016, and SB GE90 SB 79-0058, Revision 02, dated 
August 5, 2016. This service information describes procedures to 
replace and repair a main heat exchanger. These documents are distinct 
since they apply to different engine models.
    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.

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 require replacing the affected main heat 
exchangers with a part eligible for installation.

Costs of Compliance

    We estimate that this proposed AD affects 185 engines installed on 
airplanes of U.S. registry. We estimate the following costs to comply 
with this proposed AD:

                                     hour = $425.
----------------------------------------------------------------------------------------------------------------

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, 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.
