Engines 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede an existing airworthiness 

directive (AD) for certain RR RB211–524 

series turbofan engines. That AD 

currently requires initial and repetitive 

borescope inspections of the head 

section and meterpanel assembly of the 

combustion liner, and replacement if 

necessary with serviceable parts. This 

proposed AD would require those same 

inspections, and replacement if 

necessary with serviceable parts. This 

proposed AD would also add more part 

number (P/N) combustion liners to the 

applicability of this proposed AD. This 

proposed AD results from an inquiry 

submitted by an operator, which 

resulted in RR performing a complete 

review of the affected front combustion 

liner part numbers. We are proposing 

this AD to prevent deterioration of the 

engine combustion liner, which can 

result in combustion liner breakup, case 

burn-through, engine fire, and damage 

to the airplane. 

DATES: We must receive any comments 

on this proposed AD by May 1, 2009.

AD.

Discussion 

On December 20, 2004, the FAA 

issued AD 2004–26–05, Amendment 

39–13917 (70 FR 680, January 5, 1005). 

That AD requires initial and repetitive 

borescope inspections of the 

combustion liner head section and 

meterpanel assembly of the combustion 

liner and replacement if necessary, with 

serviceable parts. That action also 

reduces the inspection intervals of 

certain RB211–524 engine models that 

have not been repaired to RR Field 

Repair Scheme FRS5367/B, and requires 

a mandatory terminating action to be 

completed by a certain date. The Civil 

Aviation Authority (CAA), which is the 

airworthiness authority for the United 

Kingdom, notified the FAA that an 

unsafe condition may exist on RR 

RB211–524 series turbofan engines. The 

CAA advises that in August 2002, an 

RB211–524B engine suffered a 

combustion case burn-through as a 

result of combustor head breakup. The 

combustor head was previously 

inspected within the inspection interval 

specified in RR Service Bulletin (SB) 

No. RB.211–72–B482, Revision 8, dated 

November 15, 2001, only 228 cycles 

before the event. Subsequent to the 

original AD, RR has issued several 

revisions to SB No. RB.211–72–B482 to 

expand the applicability and clarify or 

revise the inspection requirements. In 

2003, RR issued Alert Service Bulletin 

(ASB) No. RB.211–72–AB482, Revision 

9, dated July 28, 2003, to reduce the 

inspection interval for RB211–524B–02, 

–524B2, –524B3, and –524B4 engines 

that have not been repaired to RR Field 

Repair Scheme FRS5367/B. This 

condition, if not corrected, could result 

in deterioration of the engine 

combustion liner, which can result in 


erowe on PROD1PC63 with PROPOSALS-1
Federal Register / Vol. 74, No. 39 / Monday, March 2, 2009 / Proposed Rules 9051 

combustion liner breakup, case burnthrough, and engine fire. 

Actions Since AD 2004–26–05 Was 

Issued 

Since that AD was issued, an operator 

submitted an inquiry which resulted in 

RR performing a complete review of the 

affected front combustion liner part 

numbers. Rolls-Royce identified a 

number of P/Ns that must be included 

in the inspection requirements of this 

proposed AD. 

Relevant Service Information 

We have reviewed and approved the 

technical contents of the following RR 

SBs: 

• RR ASB No. RB.211–72–AB482, 

Revision 9, dated July 28, 2003, which 

describes the initial inspection 

procedures to detect cracking of the 

combustion liner head section and the 

meterpanel. This ASB also describes the 

compliance intervals to do the initial 

and repetitive inspections. 

• RR SB No. RB.211–72–9670, dated 

August 27, 1993, which describes the 

procedures to incorporate the improved 

combustion liner head with C263 

material, and to incorporate local 

thickened diffuser walls around the 

struts for engine models –524B–02, 

–524B2, –524B3, –524B4, –524C2 and 

–524D4. 

• RR SB No. RB.211–72–9764, 

Revision 3, dated January 16, 1998, 

which describes the procedures to 

incorporate the improved combustion 

liner with strengthened head and 

improved heat shields for engine 

models –524G and –524H. 

The CAA classified ASB No. RB.211– 

72–AB482, Revision 9, dated July 28, 

2003, as mandatory and issued AD G– 

2003–0011 (previously 005–07–95), 

dated October 1, 2003, in order to 

ensure the airworthiness of these RR 

engines in the United Kingdom. 

Bilateral Agreement Information 

This engine model is manufactured in 

the United Kingdom and is type 

certificated for operation in the United 

States under the provisions of Section 

21.29 of the Federal Aviation 

Regulations (14 CFR 21.29) and the 

applicable bilateral airworthiness 

agreement. Under this bilateral 

airworthiness agreement, the CAA kept 

us informed of the situation described 

above. We have examined the findings 

of the CAA, reviewed all available 

information, and determined that AD 

action is necessary for products of this 

type design that are certificated for 

operation in the United States. 

FAA’s Determination and Requirements 

of the Proposed AD 

We have evaluated all pertinent 

information and identified an unsafe 

condition that is likely to exist or 

develop on other products of this same 

type design. We are proposing this AD, 

which would require: 

• Initial and repetitive borescope 

inspections of the combustion liner 

head section and meterpanel assembly 

of the combustion liner and, if 

necessary, replacement. 

• Reduction of the inspection 

intervals of certain RB211–524 engine 

models that have not been repaired to 

RR Field Repair Scheme FRS5367/B, 

and 

• A mandatory terminating action to 

the repetitive inspections to be 

completed no later than December 31, 

2012. 

The proposed AD would require that 

you do these actions using the service 

information described previously. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 18 engines installed on 

airplanes of U.S. registry. We also 

estimate that it would take about 2 

work-hours per engine to perform the 

proposed actions, and that the average 

labor rate is $80 per work-hour. No parts 

are required, so parts would cost about 

$0. Based on these figures, we estimate 

the total cost of the proposed AD to U.S. 

operators to be $2,880. 

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 

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 that the proposed AD: 

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); and 

3. Would not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this proposed AD. See the ADDRESSES

section for a location to examine the 

regulatory evaluation.
