70200 Federal Register / Vol. 78, No. 227 / Monday, November 25, 2013 / Rules and Regulations 

(a) Effective Date 

This AD becomes effective December 30, 

2013. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to all Rolls-Royce 

Deutschland Ltd & Co KG (RRD) model Tay 

620–15, 650–15, and 651–54 turbofan 

engines. 

(d) Reason 

This AD was prompted by excessive 

deterioration of the high-pressure (HP) air 

bleed valve operating mechanism which is 

influencing the aerodynamic fan flutter 

margin. This condition, if not corrected, 

could lead to multiple fan blade failure. We 

are issuing this AD to prevent multiple fan 

blade failure, which could result in 

uncontained engine failure and damage to 

the airplane.

mechanism. Use paragraphs 3.D. and 3.E. of 

RRD Alert Non-Modification Service Bulletin 

(NMSB) No. TAY–75–A1784, Revision 1, 

dated May 30, 2013, to do your inspection. 

(2) If the measured torque necessary to 

open and close the HP air bleed valve is 

higher than the torque values referenced in 

paragraph 3.D.(1)(a)[1] for the Tay 620–15 

and 650–15 engines, or 3.D.(2)(a)[1] for the 

Tay 651–54 engine, of RRD Alert NMSB No. 

TAY–75–A1784, Revision 1, dated May 30,

SUPPLEMENTARY INFORMATION: 

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued AD No. 2013– 

0236, dated September 25, 2013 


emcdonald on DSK67QTVN1PROD with RULES
Federal Register / Vol. 78, No. 227 / Monday, November 25, 2013 / Rules and Regulations 70201 

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

correct an unsafe condition for the 

specified products. The MCAI states: 

During repair in the wing tank area it was 

discovered that, when the tank is filled to a 

maximum level, fuel can soak into the upper 

shell sandwich of the wings. This can be 

detected from damaged finishing of the upper 

wing shells or from yellow discoloured 

bonding wire insulation. 

The root cause is a defective sealing of a 

tapped through bore hole at the inside of the 

fuel tank openings in combination with 

prolonged periods at maximum fuel level. 

This condition, if not detected and 

corrected, could cause long-term structural 

degradation of the wing structure. 

To address this potential unsafe condition, 

AQUILA issued Service Bulletin (SB)–AT01– 

027 providing instructions for the inspection 

and sealing of tapped bore holes inside both 

fuel tank openings. 

For the reasons described above, this AD 

requires repetitive inspections of the wing 

tank area and, depending on findings, 

corrective actions. 

You may examine the MCAI on the 

Internet at http://www.regulations.gov 

by searching for and locating it in 

Docket No. FAA–2013–0963. 

Relevant Service Information 

AQUILA Aviation GmbH issued 

Vorgeschrieben Technische Mitteilung 

SB–AT01–027, dated August 15, 2013 

(English translation: Mandatory Service 

Bulletin SB–AT01–027, Issue A.02, 

dated August 15, 2013). The actions 

described in this service information are 

intended to correct the unsafe condition 

identified in the MCAI. 

FAA’s Determination and Requirements 

of the AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with this State of 

Design Authority, they have 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 the State of 

Design Authority and determined the 

unsafe condition exists and is likely to 

exist or develop on other products of the 

same type design. 

FAA’s Determination of the Effective 

Date 

An unsafe condition exists that 

requires the immediate adoption of this 

AD. The FAA has found that the risk to 

the flying public justifies waiving notice 

and comment prior to adoption of this 

rule because there are no airplanes 

currently on the U.S. registry and thus, 

does not have any impact upon the 

public. Therefore, we find that notice 

and opportunity for prior public 

comment are unnecessary. 

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–2013–0963; 

Directorate Identifier 2013–CE–034– 

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 we receive 

about this AD. 

Costs of Compliance 

We estimate that this AD will affect 0 

products of U.S. registry. We also 

estimate that it will take about 2 workhours per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Based on these figures, we estimate 

the cost of this AD on U.S. operators to 

be $0, or $0 per product. 

In addition, we estimate that any 

necessary follow-on actions will take 

about 2 work-hours and require parts 

costing $100, for a cost of $270 per 

product. We have no way of 

determining the number of products 

that may need these actions. 

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 

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 

the DOT Regulatory Policies and 

Procedures (44 FR 11034, February 26, 

1979), 

(3) Will not affect intrastate aviation 

in Alaska, 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.
