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 ACO, send it to the 

attention of the person identified in the 

Related Information section of this AD.

notify your appropriate principal inspector, 

or lacking a principal inspector, the manager 

of the local flight standards district office/ 

certificate holding district office. 

(3) An AMOC that provides an acceptable 

level of safety may be used for any repair 

required by this AD if it is approved by the 

Boeing Commercial Airplanes ODA that has 

been authorized by the Manager, Seattle 

ACO, to make those findings. For a repair 

method to be approved, the repair must meet 

the certification basis of the airplane, and the 

approval must specifically refer to this AD. 

(4) AMOCs approved previously in 

accordance with AD 99–08–23, Amendment 

39–11132 (64 FR 19879, April 23, 1999), are

Airworthiness Directives; International

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

International Aero Engines AG (IAE), 

V2525–D5 and V2528–D5 turbofan 

engines, with a certain number (No.) 4 

bearing internal scavenge tube and a 

certain No. 4 bearing external scavenge 

tube installed. This proposed AD was 

prompted by a report of an engine 

under-cowl fire and commanded inflight shutdown. This proposed AD 

would require replacement of certain 

part number (P/N) No. 4 bearing internal 

scavenge tubes, and alignment checks of 

certain P/N No. 4 bearing external 

scavenge tubes. We are proposing this 

AD to prevent engine fire and damage 

to the airplane.

SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments about 

this proposal. Send your comments to 

an address listed under the ADDRESSES

section. Include ‘‘Docket No. FAA– 

2012–1217; Directorate Identifier 2012– 

NE–39–AD’’ at the beginning of your 

comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this proposed AD. We will 

consider all comments received by the 

closing date and may amend this 

proposed AD because of those 

comments. 

We will post all comments we 

receive, without change, to http:// 

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about this proposed AD. 

Discussion 

We received a report of a fire warning 

on an IAE V2525 turbofan engine 

shortly after takeoff. The engine 

experienced an under-cowl fire and a 

commanded in flight shutdown. 

Investigation revealed that this event 

was caused by failure of the No. 4 

bearing internal scavenge tube due to 

high stress. A misalignment of the No. 

4 bearing external scavenge tube was 

noted to be a contributing factor. This 

proposed AD would direct the 

replacement of all No. 4 bearing internal 

scavenge tubes, P/N 2A2074–01. This 

proposed AD would also require 

checking the alignment of the No. 4 

bearing external scavenge tube, P/N 

6A5254, and if it fails the check, 

replacement of the external scavenge 

tube. These conditions, if not corrected, 

could result in engine fire and damage 

to the airplane. 

Relevant Service Information 

We reviewed IAE Service Bulletin 

(SB) No. V2500–ENG–72–0630, 

Revision 1, dated September 20, 2012. 

The SB describes procedures for 

replacement of the No. 4 bearing 

internal scavenge tube and for 

verification of proper alignment of the 

No. 4 bearing external scavenge tube. 

FAA’s Determination 

We are proposing this AD because we 

evaluated all the relevant information 

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 the 

replacement of the No. 4 bearing 

internal scavenge tube, P/N 2A2074–01, 

at the next combustor module-level 

exposure. This AD would also require 

verification of the alignment and 

installation of the No. 4 bearing external 

scavenge tube, P/N 6A5254, relative to 

the tube-to-boss elbow, P/N 2A2514 or 

P/N 2A3951–01, on the No. 4 bearing 

internal scavenge tube, P/N 2A2074–01. 

Differences Between the Proposed AD 

and the Service Information 

The SB requires replacement of the 

No. 4 bearing internal scavenge tube, P/ 

N 2A2074–01, at each combustor 

module-level exposure. This AD would 

require replacement at each combustor 

module-level exposure after 10,000 

cycles. 

Interim Action 

We consider this proposed AD 

interim action. The design approval 

holder is currently developing a 

modification that will address the 

unsafe condition identified in this AD. 

Once this modification is developed, 

approved, and available, we might 

consider additional rulemaking. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 123 engines installed on 

airplanes of U.S. registry. We estimate 

that it would take 1.5 hours per engine 

to replace the No. 4 bearing internal 

scavenge tube, and 3 hours per engine 

to replace the No. 4 bearing external 

scavenge tube. Required parts would 

cost $25,251 per engine. The average 

labor rate is $85 per hour. Based on 

these figures, we estimate the cost of the 

proposed AD on U.S. operators to be 

$3,152,921. 

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 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 


srobinson on DSK4SPTVN1PROD with 
1778 Federal Register / Vol. 78, No. 6 / Wednesday, January 9, 2013 / Proposed Rules 

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 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.
