caused by russeting which means that
apples meet the russeting requirements
for U.S. Fancy as defined under the
definitions of ‘‘damage by russeting,’’
except the aggregate area of an apple
which may be covered by smooth netlike russeting shall not exceed 25
percent; and the aggregate area of an
apple which may be covered by smooth
solid russeting shall not exceed 10
percent: Provided, That, in the case of
the Yellow Newtown or similar
varieties, the aggregate area of an apple
which may be covered with smooth
solid russeting shall not exceed 20
percent; and that smooth net-like
russeting shall not be scored against the
Fuji variety under any circumstances.
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. Faded brown stripes shall not
be considered as color.
(b) Color standards USDA Visual Aid
APL–CC–1 (Plates a–e) consists of a
folder containing the color requirements
for apples set forth in this section and
five plates illustrating minimum good
shade of solid red or striped red color,

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:

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.

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,

Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG
Turbofan Engines
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to adopt a new airworthiness directive (AD) for
certain Rolls-Royce Deutschland Ltd & Co KG (RRD) model Tay 611-8C
turbofan engines. This proposed AD was prompted by reports of low-
pressure compressor (LPC) rotor blade retention lug failures. This
proposed AD would limit the service life of the LPC rotor blades based
on the number of dry-film lubricant (DFL) re-applications. We are
proposing this AD to address the unsafe condition on these products.
DATES: We must receive comments on this proposed AD by June 20, 2019.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

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:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Record Search to establish number of 1.5 work-hours x $85 per $0 $127.50 $1,530
DFL applications. hour = $127.50.
----------------------------------------------------------------------------------------------------------------
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.

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
