Federal Register / Vol. 78, No. 170 / Tuesday, September 3, 2013 / Rules and Regulations 54149 

to conform to any recomputed average. 

The Committee expects to carry a 

$25,000 reserve into the 2013–14 crop 

year. It expects to add $11,300 to the 

reserve during the year, for a desired 

carryout of approximately $36,300, 

which is below the limit specified in the 

order. 

The Committee reviewed and 

unanimously recommended 2013–14 

crop year expenditures of $97,700. Prior 

to arriving at this budget, the Committee 

considered information from various 

sources, such as the Committee’s 

Marketing Subcommittee and Budget 

Committee. Alternative expenditure 

levels and assessment rates were 

discussed by these groups, based upon 

the relative value of various projects to 

the date industry. The assessment rate 

of $0.40 per hundredweight of dates was 

then recommended after consideration 

of several factors, including the 

anticipated 2013–14 crop size, the 

Committee’s estimates of the incoming 

reserve funds and other income, and 

their anticipated expenses. 

A review of historical and preliminary 

information pertaining to the upcoming 

crop year indicates that the grower price 

for the 2013–14 crop year could range 

between $45.00 and $55.00 per 

hundredweight of dates. Utilizing these 

estimates and the assessment rate of 

$0.40 per hundredweight, the estimated 

assessment revenue for the 2013–14 

crop year as a percentage of total grower 

revenue could range between 0.7 and 

0.9 percent. 

This action decreases the assessment 

obligation imposed on handlers. 

Assessments are applied uniformly on 

all handlers, and some of the costs may 

be passed on to producers. However, 

decreasing the assessment rate reduces 

the burden on handlers, and may reduce 

the burden on producers. In addition, 

the Committee’s meeting was widely 

publicized throughout the California 

date industry, and all interested persons 

were invited to attend the meeting and 

encouraged to participate in Committee 

deliberations on all issues. Like all 

Committee meetings, the June 20, 2013, 

meeting was a public meeting and all 

entities, both large and small, were able 

to express views on this issue. Industry 

members also discussed the various 

possible assessment rates, potential crop 

size, and estimated expenses at the 

Budget Committee meeting on June 6, 

2013. Finally, interested persons are 

invited to submit comments on this 

interim rule, including the regulatory 

and informational impacts of this action 

on small businesses. 

In accordance with the Paperwork 

Reduction Act of 1995, (44 U.S.C. 

Chapter 35), the order’s information 

collection requirements have been 

previously approved by the Office of 

Management and Budget (OMB) and 

assigned OMB No. 0581–0178, 

‘‘Vegetable and Specialty Crop 

Marketing Orders.’’ No changes in those 

requirements as a result of this action 

are necessary. Should any changes 

become necessary, they would be 

submitted to OMB for approval. 

This action imposes no additional 

reporting or recordkeeping requirements 

on either small or large Riverside 

County, California date handlers. As 

with all Federal marketing order 

programs, reports and forms are 

periodically reviewed to reduce 

information requirements and 

duplication by industry and public 

sector agencies. 

AMS is committed to complying with 

the E-Government Act, to promote the 

use of the internet and other 

information technologies to provide 

increased opportunities for citizen 

access to Government information and 

services, and for other purposes. 

USDA has not identified any relevant 

Federal rules that duplicate, overlap, or 

conflict with this rule. 

A small business guide on complying 

with fruit, vegetable, and specialty crop 

marketing agreements and orders may

Any questions about the compliance 

guide should be sent to Jeffrey Smutny 

at the previously mentioned address in

section. 

After consideration of all relevant 

material presented, including the 

information and recommendation 

submitted by the Committee and other 

available information, it is hereby found 

that this rule, as hereinafter set forth, 

will tend to effectuate the declared 

policy of the Act. 

Pursuant to 5 U.S.C. 553, it is also 

found and determined upon good cause 

that it is impracticable, unnecessary, 

and contrary to the public interest to 

give preliminary notice prior to putting 

this rule into effect, and that good cause 

exists for not postponing the effective 

date of this rule until 30 days after 

publication in the Federal Register 

because: (1) The 2013–14 crop year 

begins on October 1, 2013, and the 

marketing order requires that the rate of 

assessment for each crop year apply to 

all assessable dates handled during such 

crop year; (2) the action decreases the 

assessment rate for assessable dates 

beginning with the 2013–14 crop year; 

(3) handlers are aware of this action 

which was unanimously recommended 

by the Committee at a public meeting 

and is similar to other assessment rate 

actions issued in past years; and (4) this 

interim rule provides a 60-day comment 

period, and all comments timely 

received will be considered prior to 

finalization of this rule.

ACTION: Final rule. 

SUMMARY: We are superseding 

airworthiness directive (AD) 2012–10– 

12 for all RR RB211–Trent 553–61, 

553A2–61, 556–61, 556A2–61, 556B–61,

17, 884B–17, 892–17, 892B–17, and 

895–17 turbofan engines. AD 2012–10– 

12 required inspecting the intermediatepressure (IP) compressor rotor shaft rear 

balance land for cracks. We are issuing 

this AD to require inspections of the IP 

compressor rotor shaft, as required by 

AD 2012–10–12, to add on-wing 


pmangrum on DSK3VPTVN1PROD with RULES
54150 Federal Register / Vol. 78, No. 170 / Tuesday, September 3, 2013 / Rules and Regulations 

inspections for the Trent 500 engines, 

and to add on-wing and in-shop 

inspections for the Trent 900 engines. 

This AD was prompted by detection of 

a crack in a Trent 500 IP compressor 

rotor shaft rear balance land during a 

shop visit. Further engineering 

evaluation, done by RR, concluded that 

the cracking may also exist in Trent 900 

engines. We are issuing this AD to 

detect cracking on the IP compressor 

rotor shaft rear balance land, which 

could lead to uncontained engine failure 

and damage to the airplane.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2012–10–12, 

Amendment 39–17061 (77 FR 31176, 

May 25, 2012). AD 2012–10–12 applied 

to the specified products. The NPRM 

published in the Federal Register on 

March 21, 2013 (78 FR 17300). The 

NPRM proposed to require inspections 

of the IP compressor rotor shaft, as 

required by AD 2012–10–12, on-wing 

inspections for the Trent 500 engines, 

and on-wing and in-shop inspections for 

the Trent 900 engines. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the proposal and the FAA’s 

response to each comment. 

Request To Not Include Revision Level 

of Service Bulletin (SB) 

Texas Aero Engine Service LLC 

(TAESL) requested that we not include 

the revision of the SB or that we include 

‘‘or later revision’’ in the AD. The 

commenter’s justification for this 

request is that the SBs are revised often. 

We do not agree. The SBs contain 

unique methods that require IBR. We do 

not know how a SB will be revised in 

the future; therefore, we cannot use ‘‘or 

later revision’’. Any future revisions can 

be addressed using paragraph (m) of this 

AD. We did not change the AD. 

Request To Include an Alternate 

Method of Compliance 

TAESL requested that RR SB No. 

RB.211–72–AG401 be included as an 

alternative means of compliance and 

that the requirement to perform an eddy 

current inspection (ECI), on engines 

which have had the new balance 

weights fitted using RR SB No. RB.211– 

72–AG401, be removed. The 

justification for this request is that the 

SB describes procedures for replacing 

the existing balance weights with new 

balance weights. 

We do not agree. The unsafe 

condition was identified in the existing 

balance weights that were installed. RR 

SB No. RB.211–72–AG401 introduces 

the new balance weights. In paragraph 

(j) of this AD we mandate removal of the 

existing balance weights as terminating 

action, as opposed to installation of the 

new balance weights. We did not IBR 

RR SB No. RB.211–72–AG401 because 

there could be future versions of the 

balance weights that would also be 

acceptable. We did not change the AD. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting this AD 

as proposed except for minor editorial 

changes. We have determined that these 

minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (78 FR 

17300, March 21, 2013) for correcting 

the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (78 FR 17300, 

March 21, 2013). 

Costs of Compliance 

We estimate that this AD will affect 

about 136 engines installed on airplanes 

of U.S. registry. We also estimate that it 

will take about 14 hours per engine to 

perform the required inspections. The 

average labor rate is $85 per hour. 

Replacement parts are estimated to cost 

about $2,271 per engine. Based on these 

figures, we estimate the cost of the AD 

on U.S. operators to be $470,696. 

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 have determined that this AD will 

not have federalism implications under 

Executive Order 13132. This AD will 

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 that this AD: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 


pmangrum on DSK3VPTVN1PROD with RULES
Federal Register / Vol. 78, No. 170 / Tuesday, September 3, 2013 / Rules and Regulations 54151 

(2) Is not a ‘‘significant rule’’ under 

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.

Airworthiness Directives; Rolls-Royce 

plc Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Rolls-Royce plc (RR) RB211–524B–02; 

–524B2–19; –524B3–02; –524B4–02; 

–524C2–19; –524D4–19; –524D4–B–19; 

–524D4–39; –535C–37; –535E4–37; 

–535E4–B–37, and –535E4–B–75 

turbofan engines, and all RB211– 

524G2–19; –524G3–19; –524H2–19; and 

–524H–36 turbofan engines. This AD 

requires a one-time inspection of the 

front combustion liner (FCL) metering 

panel to determine if it is made from 

N75 material and, if so, replacing it with 

an FCL made from C263 material. This 

AD was prompted by the discovery of a 

cracked and distorted FCL metering 

panel, which was made from N75 

material. We are issuing this AD to 

prevent hot gases from burning through 

the engine casing, which could result in 

an under-cowl fire and damage to the 

airplane. 

DATES: This AD becomes effective 

October 8, 2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of October 8, 2013. 

ADDRESSES: The Docket Operations 

office is located at Docket Management 

Facility, U.S. Department of 

Transportation, 1200 New Jersey 

Avenue SE., West Building Ground 

Floor, Room W12–140, Washington, DC 

20590–0001.
