39–14343; AD 2005–21–05] 

RIN 2120–AA64 

Airworthiness Directives; Rolls-Royce 

Deutschland Ltd & Co KG (Formerly 

Rolls-Royce Deutschland GmbH, 

formerly BMW Rolls-Royce GmbH) 

Models BR700–710A1–10 and BR700–

710A2–20 Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is superseding an 

existing airworthiness directive (AD) for 

Rolls-Royce Deutschland Ltd & Co KG 

(RRD) (formerly Rolls-Royce 

Deutschland GmbH, formerly BMW 

Rolls-Royce GmbH) models BR700–

710A1–10 and BR700–710A2–20 

turbofan engines. That AD currently 

requires initial and repetitive visual and 

ultrasonic inspections of fan discs, part 

numbers (P/Ns) BRR18803, BRR19248, 

and BRR20791 for cracks, and if 

necessary, replacement with serviceable 

parts. This ad requires those same 

inspections for discs having old design 

P/N fan blades installed, and, extends 

the inspection interval for fan discs 

having new design P/N fan blades 

installed. Also, this AD adds as optional 

terminating action to the inspections, 

installation of certain P/N new fan 

discs, certain P/N new fan blades, and 

engine fan speed (N1) Keep Out Zone 

software. This AD results from a revised 

RRD service bulletin (SB) that 

introduces relaxed inspection intervals 

for certain P/N combinations of fan 

discs and fan blades, and introduces 

improved design fan discs and fan 

blades. 

DATES: This AD becomes effective 

November 25, 2005. The Director of the 

Federal Register approved the 

incorporation by reference of certain 

publications listed in the regulations as 

of November 25, 2005. The Director of 

the Federal Register previously 

approved the incorporation by reference 

of certain other publications as listed in 

the regulations as of April 28, 2003 (68 

FR 17727, April 11, 2003).

SUPPLEMENTARY INFORMATION: The FAA 

proposed to amend 14 CFR part 39 with 

a proposed AD. The proposed AD 

applies to Rolls-Royce Deutschland Ltd 

& Co KG (RRD) (formerly Rolls-Royce 

Deutschland GmbH, formerly BMW 

Rolls-Royce GmbH) models BR700–

710A1–10 and BR700–710A2–20 

turbofan engines. We published the 

proposed AD in the Federal Register on 

July 5, 2005 (70 FR 38627). That action 

proposed to require initial and 

repetitive inspections for cracks in fan 

discs P/Ns BRR18803, BRR19248, 

BRR20791, BRR24829, and FW33929. 

That action also proposed as optional 

terminating action to the repetitive 

inspection requirements, installation of 

a new fan disc P/N FW33927, new fan 

blades P/N FW33513 or P/N FW33980, 

and N1 Keep Out Zone software. 

Examining the AD Docket 

You may examine the AD Docket 

(including any comments and service 

information), by appointment, between 

8 a.m. and 4:30 p.m., Monday through 

Friday, except Federal holidays. See 

ADDRESSES for the location. 

61230 Federal Register / Vol. 70, No. 203 / Friday, October 21, 2005 / Rules and Regulations 

Comments 

We provided the public the 

opportunity to participate in the 

development of this AD. We have 

considered the comments received. 

Request To Cancel Inspections 

One commenter, RRD, requests we 

cancel the inspections in paragraphs 

(f)(1), (g)(1), (f)(3), and (g)(3), as these 

inspections have been conducted on all 

hardware in service, and are no longer 

needed. We disagree. Mandatory actions 

that published in the superseded AD 

need to be carried forward in the 

superseding AD. The operator can then 

determine if the affected engine is in 

compliance with all mandatory actions. 

Add Applicable Fan Blade Part 

Numbers to Paragraph (h) 

The same commenter requests that we 

add the applicable fan blade part 

numbers in paragraph (h), for clarity, as 

we did in paragraph (g). We agree and 

have added fan blades P/N BRR20677 

and BRR23178 to paragraph (h). 

Request To Cover Engines That Had a 

New Disc Installed on, or After, 

January 1, 2002 

The same commenter requests that we 

cover engines that had a new 

production fan disc installed on or after 

January 1, 2002, in a new paragraph in 

the compliance section. The commenter 

states that these fan discs already had a 

visual and ultrasonic inspection before 

delivery and installation, and only 

require initial inspection at 150 flight 

cycles-since-new. These engines are not 

appropriately covered by the proposed 

AD. We agree and have added a 

paragraph to the compliance section to 

cover these engines. 

Request To Directly Identify 

Requirements 

The same commenter requests that we 

clarify paragraphs (i) and (j) by directly 

identifying the requirements, instead of 

referring to other paragraphs. We agree 

and have changed paragraphs (i) and (j) 

to identify the requirements. 

Request To Change Repetitive 

Inspection Interval 

The same commenter requests that in 

paragraphs (k)(1) and (k)(2), we change 

the inspection interval time requirement 

from flight hours, to A-Check. The 

commenter states that the proposed AD 

does not reflect the requirements of RRD 

SB No. SB–BR700–72–900229, Revision 

6, dated February 23, 2005. The visual 

and ultrasonic inspections were always 

aligned with the scheduled airplane 

maintenance A-Check. The commenter 

further states that the A-Check occurs 

every 500-to-550 flight hours. We 

partially agree. We consider the ACheck to occur at an indefinite interval 

that can vary from operator to operator. 

However, in this case, we have changed 

the compliance in paragraph (k)(1) to 

perform a visual and ultrasonic 

inspection before accumulating 550 

flight hours-since-new. We also changed 

paragraph (k)(2) to perform a visual and 

ultrasonic inspection at every A-Check 

but not to exceed 550 hours-since-the 

last visual and ultrasonic inspection. 

Request To Remove Inspection 

Requirements From the AD and 

Reference the Time Limits Manual 

The same commenter requests that we 

remove the inspection requirements 

from paragraph (l) of the proposed AD, 

which is for engines with fan disc P/N 

BRR20791, BRR24829, or FW33929 

installed, and fan blades P/N FW33513, 

FW33980, FW33925, FW34114, or 

FW34776 installed. The commenter 

requests that we refer to the applicable 

RRD Time Limits Manual that mandates 

the inspections for these fan disc-andblade-engine configurations. We agree 

and have changed that paragraph in the 

AD. 

Request To Clarify the Optional 

Terminating Action 

The same commenter requests that in 

the optional terminating action 

paragraph, we change the phrase ‘‘is 

optional terminating action to the 

repetitive inspections required by this 

AD’’ to ‘‘is optional terminating action 

to any inspection required by this AD’’. 

The commenter states that once the 

parts and the Keep Out Zone software 

referenced in the optional terminating 

action paragraph are installed, none of 

the inspections in the AD are required. 

We agree and have made that change in 

the AD. 

Request To Reference the Latest Service 

Bulletin 

The same commenter requests that we 

reference the latest service bulletin in 

the Inspection Reporting Requirements 

paragraph, which is RRD SB No. SB–

BR700–72–900229, Revision 6, dated 

February 23, 2005. We agree and have 

made that change in the AD. 

Conclusion 

We have carefully reviewed the 

available data, including the comments 

received, and determined that air safety 

and the public interest require adopting 

the AD with the changes described 

previously. We have determined that 

these changes will neither increase the 

economic burden on any operator nor 

increase the scope of the AD. 

Costs of Compliance 

There are about 500 RRD models 

BR700–710A1–10 and BR700–710A2–

20 turbofan engines of the affected 

design in the worldwide fleet. We 

estimate that 400 engines installed on 

airplanes of U.S. registry are affected by 

this AD. We also estimate that it will 

take about 7 work hours per engine to 

perform the inspections, and that the 

average labor rate is $65 per work hour. 

We estimate the total labor cost for 

performing one inspection of the U.S. 

fleet to be $182,000. New design fan 

discs and fan blades will cost about 

$150,000 per engine. Based on these 

figures, the total cost of the AD on U.S. 

operators is estimated to be $60,182,000. 

The manufacturer has stated that it may 

provide the new fan disc and new fan 

blades at no cost to operators. 

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; 

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

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979); and 

(3) 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. 

Federal Register / Vol. 70, No. 203 / Friday, October 21, 2005 / Rules and Regulations 61231 

We prepared a summary of the costs 

to comply with this AD and placed it in 

the AD Docket. You may get a copy of 

this summary by sending a request to us 

at the address listed under ADDRESSES. 

Include ‘‘AD Docket No. 2000–NE–48–

Pesticides; Emergency Exemption

Secretary of Agriculture 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Notification to the Secretary of 

Agriculture. 

SUMMARY: This document notifies the 

public that the Administrator of EPA 

has forwarded to the Secretary of 

Agriculture a draft final rule as required 

by section 25(a) of the Federal 

Insecticide, Fungicide, and Rodenticide 

Act (FIFRA). As described in the 

Agency’s semi-annual Regulatory 

Agenda, the draft final rule will make 

several improvements to the pesticide 

emergency exemption process under 

section 18 of FIFRA. EPA has 

established regulations under section 18 

of FIFRA which allow a Federal or State 

agency to apply for an emergency 

exemption to allow an unregistered use 

of a pesticide for a limited time when 

such use is necessary to alleviate an 

emergency condition.
