AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Rolls-Royce plc (RR) RB211-Trent 970– 

84, RB211-Trent 970B–84, RB211-Trent 

972–84, RB211-Trent 972B–84, RB211- 

Trent 977–84, RB211-Trent 977B–84, 

and RB211-Trent 980–84 turbofan 

engines. This AD requires inspection of 

the intermediate pressure compressor 

rear stub shaft (IPC RSS) piston ring. 

This AD was prompted by the failure of 

an oil pump drive shear neck due to a 

piston ring seal that was not seated 

properly in the IPC RSS groove. We are 

issuing this AD to prevent failure of the 

oil pump drive shear neck, which could 

result in loss of oil pressure in one or 

more engines and reduced control of the 

airplane. 

DATES: This AD becomes effective April 

30, 2013. 

We must receive comments on this 

AD by May 30, 2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of April 30, 2013.

SUPPLEMENTARY INFORMATION: 

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2012–0273, 

dated December 21, 2012, a Mandatory 

Continuing Airworthiness Information 

(referred to after this as ‘‘the MCAI’’), to 

correct an unsafe condition for the 

specified products. The MCAI states: 

During take-off of an A380 on a customer 

acceptance flight, a low oil pressure warning 

message was observed by the flight crew. The 

take-off was aborted and the aircraft returned 

to the gate without further incident. Initial 

post-flight inspection of the engine revealed 

that the oil pump drive shear neck had failed. 

Upon further inspection of the engine, pieces 

of debris were found in the oil pump Internal 

Gear Box (IGB) rear scavenge screen and 

smaller pieces of profiled debris were found 

on the Electrical Magnetic Chip Detector 

(EMCD). From the material recovered, the 

origin was found to be the piston ring seal, 

which fits in the groove of the Intermediate 

Pressure Compressor Rear Stub Shaft (IPC 

RSS). This piston ring was introduced as part 

of Rolls-Royce Mod.72–G585 which 

incorporated a modified 52-spline IP Turbine 

Shaft, IPC RSS and coupling assembly. 

Therefore, only engines incorporating 

Mod.72–G585 are affected. 

This condition, if not detected and 

corrected, could lead to loss of oil pressure 

on one or more of the engines, possibly 

resulting in reduced control of the aeroplane. 

The failure to properly seat the piston 

ring seal in the groove of the IPC RSS 

occurs during assembly of the shaft. 

This could cause the movement of the 

ring out of the groove and resulting 

forces during operation may cause 

fracture of the ring. You may obtain 

further information by examining the 

MCAI in the AD docket. 

Relevant Service Information 

RR has issued Repeater Technical 

Variance 129978, Issue 1, dated 

December 19, 2012 and Issue 2, dated 

December 20, 2012; Repeater Technical 

Variance 129940, Issue 1, dated 

December 20, 2012; and Repeater 

Technical Variance 129994, Issue 1, 

dated December 19, 2012. The actions 

described in this service information are 

intended to correct the unsafe condition 

identified in the MCAI. 

FAA’s Determination and Requirements 

of This AD 

This product has been approved by 

the United Kingdom 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 

issuing this AD because we evaluated 

all information provided by EASA and 

determined the unsafe condition exists 

and is likely to exist or develop on other 

products of the same type design. This 

AD requires inspection of the IPC RSS 

piston ring. 

Differences Between the AD and the 

MCAI or Service Information 

This AD requires compliance for all 

engines within 50 cycles of the effective 

date of this AD. The MCAI requires a 

staggered compliance interval based on 

the number of affected engines on the 

airplane. Our AD uses a more 

conservative compliance time because 

there are no engines installed on aircraft 

of U.S. registry that will be affected. 

FAA’s Determination of the Effective 

Date 

No domestic operators use this 

product. Therefore, we find that notice 

and opportunity for prior public 

comment are unnecessary and that good 

cause exists for making this amendment 

effective in less than 30 days. 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety, and 

we did not precede it by notice and 

opportunity for public comment. We 

invite you to send any written relevant 

data, views, or arguments about this AD. 

Send your comments to an address 

listed under the ADDRESSES section. 

Include ‘‘Docket No. FAA–2013–0196; 

Directorate Identifier 2013–NE–03–AD’’ 

at the beginning of your comments. We 

specifically invite comments on the 

overall regulatory, economic, 

environmental, and energy aspects of 

this AD. We will consider all comments 

received by the closing date and may 

amend this 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 with FAA 

personnel concerning this AD. Using the 

search function of the Web site, anyone 

can find and read the comments in any 

of our dockets, including, if provided, 

the name of the individual who sent the 

comment (or signed the comment on 

behalf of an association, business, labor 

union, etc.). You may review the DOT’s 

complete Privacy Act Statement in the 

Federal Register published on April 11, 

2000 (65 FR 19477–78). 

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 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 

mstockstill on DSK4VPTVN1PROD with RULES

22182 Federal Register / Vol. 78, No. 72 / Monday, April 15, 2013 / Rules and Regulations 

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 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. 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD docket.

Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all The 

Boeing Company Model 737–600, –700, 

–700C, –800, –900, and –900ER series 

airplanes. This AD was prompted by 

reports of an incorrect procedure used 

to apply the wear and corrosion 

protective surface coating to attach pins 

of the horizontal stabilizer rear spar. 

This AD requires inspecting to 

determine the part number of the attach 

pins of the horizontal stabilizer rear 

spar, and replacing certain attach pins 

with new, improved attach pins. We are 

issuing this AD to prevent premature 

failure of the attach pins, which could 

cause reduced structural integrity of the 

horizontal stabilizer to fuselage 

attachment, resulting in loss of control 

of the airplane. 

DATES: This AD is effective May 20, 

2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of May 20, 2013.
