Each apple of this grade has the amount of color specified in § 51.305 for the variety. Invisible watercore shall not be scored in this grade. (See § 51.305 and § 51.306.) * * * * * ■ 5. Revise § 51.305 to read as follows: § 51.305 Color Requirements. (a) In addition to the requirements specified for the grades set forth in §§ 51.300 to 51.304, apples of these grades shall have the percentage of color specified for the variety in table I appearing in this section. All apple varieties other than those appearing in table I shall have no color requirements pertaining to these grades. For the solid red varieties, the percentage stated refers to the area of the surface which must be covered with a good shade of solid red characteristic of the variety: Provided, That an apple having color of a lighter shade of solid red or striped red than that considered as a good shade of red characteristic of the variety may be admitted to a grade, provided it has sufficient additional area covered so that the apple has as good an appearance as one with the minimum percentage of good red characteristic of the variety required for the grade. For the striped red varieties, the percentage stated refers to the area of the surface in which the stripes of a good shade of red characteristic of the variety shall predominate over stripes of lighter red, green, or yellow. However, an apple having color of a lighter shade than that considered as a good shade of red characteristic of the variety may be admitted to a grade, provided it has sufficient additional area covered so that the apple has as good an appearance as one with the minimum percentage of stripes of a good red characteristic of the variety required for the grade.

We will also post a report summarizing each substantive verbal contact we receive about this NPRM. Discussion The European Union Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA AD 2018–0055, dated March 12, 2018 (referred to after this as ‘‘the MCAI’’), to address the unsafe condition on these products. The MCAI states: The airworthiness limitations for the Tay 611–8C engines, which are approved by EASA, are currently defined and published in the ALS. Among others, the ALS contains limitation(s) applicable to the maximum number of Dry Film Lubrication (DFL) treatments applied on fan blade retention lugs. These instructions have been identified as mandatory for continued airworthiness. Failure to accomplish these instructions could result in an unsafe condition. In addition to the ALS, RRD issued the NMSB to provide alternative methods to establish, in case this cannot be determined from the engine maintenance records, the number of DFL treatments that have been applied to an engine. You may obtain further information by examining the MCAI in the AD docket on the internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2019– 0213. Related Service Information Under 1 CFR Part 51 We reviewed RRD Non-Modification Service Bulletin (NMSB) TAY–72–1835, Initial Issue, dated December 15, 2017. The service information describes procedures for marking the LPC rotor blades with a suffix code during the next scheduled LPC fan blade removal. 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 This product has been approved by Germany and is approved for operation in the United States. Pursuant to our bilateral agreement with the European Community, EASA has notified us of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all the relevant information provided by EASA 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 a determination of the number of DFL reapplications that have been applied to the LPC rotor blades and, depending on the number of DFL re-applications, replacement of LPC rotor blades. Differences Between This Proposed AD and the MCAI or Service Information This proposed AD and EASA AD 2018–0055 do not include the RRD Tay 611–8 model turbofan engines in the Applicability section, while RRD NMSB TAY–72–1835, Initial Issue, dated December 15, 2017, does include this engine model. For the RRD Tay 611–8 engines, EASA has already approved the new limitation to the service life of the blade. In addition, RRD has revised the aircraft maintenance program, on the basis of which the operator or the owner ensures the continuing airworthiness of each operated airplane (on which an affected engine is installed), to limit the number of DFL applications, as specified in this AD. Costs of Compliance We estimate that this proposed AD affects 12 engines installed on airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: jbell on DSK3GLQ082PROD with PROPOSALS ESTIMATED COSTS Action Labor cost Record Search to establish number of DFL applications. 1.5 work-hours × $85 per hour = $127.50 .....

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. jbell on DSK3GLQ082PROD with PROPOSALS 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 VerDate Sep<11>2014 17:28 May 03, 2019 Jkt 247001 (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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

SUPPLEMENTARY INFORMATION: I. Background Since 2002, FHA has operated a demonstration program to implement the general authority under section 204 of the National Housing Act, 12 U.S.C. 1710, as amended by section 601 of the Fiscal Year 1999 Departments of Veterans Affairs and Housing and Urban Development and Independent Agencies Appropriations Act (Pub. L. 105–276, approved October 21, 1998) (‘‘FY 1999 Appropriations Act’’). Section 601 of the FY 1999 Appropriations Act amended section 204 to make more effective the methods for paying insurance claims and disposing of FHA-acquired single family mortgages and properties.1 Over the years, FHA has adopted various names to refer to this demonstration, including the Accelerated Claim and Asset Disposition (ACD) Demonstration, the Single Family Loan Sales (‘‘SFLS’’) Program, and the Distressed Asset Stabilization Program (‘‘DASP’’). Nonetheless, FHA has continuously operated the demonstration for the purpose of selecting a cost- and missioneffective method of paying insurance claims and disposing of acquired notes or properties under the FHA SingleFamily insurance programs. Section 204 grants FHA discretion to implement a range of disposition alternatives. This statutory provision provides FHA the flexibility to consider and make adjustments based upon current market and economic factors and conditions. Exercising this authority helps to effectively manage FHA’s defaulted assets and minimizes losses to the MMIF, thereby helping to satisfy the Secretary’s fiduciary duty to preserve the insurance fund. By notice published in the Federal Register on February 5, 2002, FHA announced its intention to establish the ACD Demonstration to ‘‘address any programmatic concerns’’ and ‘‘assess its success and determine whether to implement the ACD process on a permanent basis, throughout the country.’’ 2 As stated in the notice, ‘‘[m]ortgagee participation in the ACD [demonstration] is voluntary,’’ and interested persons could submit comments.3 Approximately eight months after publishing the February 5, 1 See 12 U.S.C. 1710(a) & (g).

Discussion

    The European Union Aviation Safety Agency (EASA), which is the 
Technical Agent for the Member States of the European Community, has 
issued EASA AD 2018-0055, dated March 12, 2018 (referred to after this 
as ``the MCAI''), to address the unsafe condition on these products. 
The MCAI states:

    The airworthiness limitations for the Tay 611-8C engines, which 
are approved by EASA, are currently defined and published in the 
ALS. Among others, the ALS contains limitation(s) applicable to the 
maximum number of Dry Film Lubrication (DFL) treatments applied on 
fan blade retention lugs. These instructions have been identified as 
mandatory for continued airworthiness.
    Failure to accomplish these instructions could result in an 
unsafe condition.
    In addition to the ALS, RRD issued the NMSB to provide 
alternative methods to establish, in case this cannot be determined 
from the engine maintenance records, the number of DFL treatments 
that have been applied to an engine.

    You may obtain further information by examining the MCAI in the AD 
docket on the internet at https://www.regulations.gov by searching for 
and locating Docket No. FAA-2019-0213.

Related Service Information Under 1 CFR Part 51

    We reviewed RRD Non-Modification Service Bulletin (NMSB) TAY-72-
1835, Initial Issue, dated December 15, 2017. The service information 
describes procedures for marking the LPC rotor blades with a suffix 
code during the next scheduled LPC fan blade removal. 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

    This product has been approved by Germany and is approved for 
operation in the United States. Pursuant to our bilateral agreement 
with the European Community, EASA has notified us of the unsafe 
condition described in the MCAI and service information referenced 
above. We are proposing this AD because we evaluated all the relevant 
information provided by EASA 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 a determination of the number of DFL 
re-applications that have been applied to the LPC rotor blades and, 
depending on the number of DFL re-applications, replacement of LPC 
rotor blades.

Differences Between This Proposed AD and the MCAI or Service 
Information

    This proposed AD and EASA AD 2018-0055 do not include the RRD Tay 
611-8 model turbofan engines in the Applicability section, while RRD 
NMSB TAY-72-1835, Initial Issue, dated December 15, 2017, does include 
this engine model. For the RRD Tay 611-8 engines, EASA has already 
approved the new limitation to the service life of the blade. In 
addition, RRD has revised the aircraft maintenance program, on the 
basis of which the operator or the owner ensures the continuing 
airworthiness of each operated airplane (on which an affected engine is 
installed), to limit the number of DFL applications, as specified in 
this AD.

Costs of Compliance

    We estimate that this proposed AD affects 12 engines installed on 
airplanes of U.S. registry.
    We estimate the following costs to comply with this proposed AD:

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

    We estimate the following costs to do any necessary replacements 
that would be required based on the results of the proposed inspection. 
We have no way of determining the number of aircraft that might need 
these replacements:

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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the

(g) Required Actions

    (1) Within 30 days after the effective date of this AD, 
determine the number of dry film lubrication (DFL) re-applications 
that were applied to each LPC rotor blade by reviewing the 
maintenance records. If a complete record of the total number of DFL 
re-applications is unavailable, count one DFL re-application for 
every 1,300 flight cycles of blade use.
    (i) If the number of DFL re-applications is less than 13, mark 
the LPC rotor blade with a suffix code during the next scheduled LPC 
fan blade removal using the instructions in the Accomplishment 
Instructions, paragraph 3.B.(1)(c)[2] or 3.F.(1)(c)[2], as 
applicable, of RRD Non-Modification Service Bulletin TAY-72-1835, 
Initial Issue, dated December 15, 2017.
    (ii) If the number of DFL treatments is 13 or more, replace the 
LPC rotor blade with a part eligible for installation before next 
flight.
    (2) [Reserved]

(h) Installation Prohibition

    After the effective date of this AD, do not install a LPC rotor 
blade on any engine unless it has been determined that the LPC rotor 
blade has less than 13 DFL re-applications and has been marked in 
accordance with paragraph (g)(1)(i) of this AD.

(i) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, ECO Branch, FAA, has the authority to approve 
AMOCs for this AD, if requested using the procedures found in 14 CFR 
39.19. In accordance with 14 CFR 39.19, send your request to your 
principal inspector or local Flight Standards District Office, as 
appropriate. If sending information directly to the manager of the 
ECO Branch, send it to the attention of the person identified in
