ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for certain International Aero Engines AG (IAE) V2500 model turbofan engines. This proposed AD was prompted by an inspection that determined that material anomalies exist in certain low-pressure turbine (LPT) stage 6 disks.

Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA– 2019–0268; Product Identifier 2019– NE–08–AD’’ at the beginning of your comments.

We will post all comments we receive, without change, to https:// 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 received reports based on an inspection of material anomalies in certain LPT stage 6 disks. A manufacturer produced 18 V2500 LPT stage 6 disks from ATI, a supplier of material ingots, in late 2017. Six of those disks were rejected prior to shipment by MTU Aero Engines, a disk supplier, for melt defects at final inspection. The other twelve disks that initially passed inspection are now considered suspect. Four disk were recovered and quarantined prior to entering into service. This AD addresses the eight remaining affected disks. The material anomaly may reduce the life of the LPT stage 6 disks; therefore, all affected disks must be removed from service within the times specified in this AD. This condition, if not addressed, could result in failure of the LPT, uncontained release of the LPT stage 6 disk, damage to the engine, and damage to the airplane. Related Service Information We reviewed IAE Alert Service Bulletin (ASB) V2500–ENG–72–A0697, Revision No. 1, dated November 27, 2018. The ASB describes procedures for removal of the affected LPT stage 6 disks. 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 removal and replacement of the affected LPT stage 6 disks. Costs of Compliance We estimate that this proposed AD affects 1 engine installed on airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: E:\FR\FM\20MYP1.SGM 20MYP1 22744 Federal Register / Vol. 84, No. 97 / Monday, May 20, 2019 / Proposed Rules ESTIMATED COSTS Action Labor cost Replace the disk ............................................. 130 work-hours × $85 per hour = $11,050 ....

Discussion

    We received reports based on an inspection of material anomalies in 
certain LPT stage 6 disks. A manufacturer produced 18 V2500 LPT stage 6 
disks from ATI, a supplier of material ingots, in late 2017. Six of 
those disks were rejected prior to shipment by MTU Aero Engines, a disk 
supplier, for melt defects at final inspection. The other twelve disks 
that initially passed inspection are now considered suspect. Four disk 
were recovered and quarantined prior to entering into service. This AD 
addresses the eight remaining affected disks. The material anomaly may 
reduce the life of the LPT stage 6 disks; therefore, all affected disks 
must be removed from service within the times specified in this AD. 
This condition, if not addressed, could result in failure of the LPT, 
uncontained release of the LPT stage 6 disk, damage to the engine, and 
damage to the airplane.

Related Service Information

    We reviewed IAE Alert Service Bulletin (ASB) V2500-ENG-72-A0697, 
Revision No. 1, dated November 27, 2018. The ASB describes procedures 
for removal of the affected LPT stage 6 disks.

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 removal and replacement of the 
affected LPT stage 6 disks.

Costs of Compliance

    We estimate that this proposed AD affects 1 engine installed on 
airplanes of U.S. registry.
    We estimate the following costs 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 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.
