This AD was prompted by reports 

indicating that a standard access door was 

located where an impact-resistant access 

door was required, and stencils were missing 

from some impact-resistant access doors. We 

are issuing this AD to prevent foreign object 

penetration of the fuel tank, which could 

cause a fuel leak near an ignition source (e.g., 

hot brakes or engine exhaust nozzle), 

consequently leading to a fuel-fed fire. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Inspections 

Within 72 months after the effective date 

of this AD, do the actions specified in

accordance with the Accomplishment 

Instructions of Boeing Service Bulletin 757– 

28–0118, dated January 12, 2012. 

(1) Do a general visual inspection of the 

left- and right-hand wing fuel tank access 

doors to determine whether impact-resistant 

access doors are installed in the correct 

locations. If any standard access door is 

found, before further flight, replace with an 

impact-resistant access door, in accordance 

with the Accomplishment Instructions of 

Boeing Service Bulletin 757–28–0118, dated 

January 12, 2012. 

(2) Do a general visual inspection of the 

left- and right-hand wing fuel tank impactresistant access doors to verify stencils and 

index markers are applied. If a stencil or 

index marker is missing, before further flight, 

apply stencil or index marker, as applicable, 

in accordance with the Accomplishment 

Instructions of Boeing Service Bulletin 757– 

28–0118, dated January 12, 2012. 

(h) Maintenance Program Revision

Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all 

Rolls-Royce Deutschland Ltd & Co KG 

(RRD) model Tay 620–15, 650–15, and 

651–54 turbofan engines. This AD 

requires a one-time inspection of the 

high-pressure (HP) air bleed valve 

operating mechanism and, depending 

on findings, corrective action. This AD 

was prompted by excessive 

deterioration of the 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. 

DATES: This AD becomes effective 

December 30, 2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of December 30, 2013.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. The 

NPRM was published in the Federal 

Register on June 13, 2013 (78 FR 35574). 

The NPRM proposed to correct an 

unsafe condition for the specified 

products. The MCAI states: 

A review of the service history of Tay 

engines discovered that the High Pressure 

(HP) air bleed valve operating mechanism is 

exposed to excessive deterioration, 

influencing the aerodynamics and stability of 

the Low Pressure (LP) compressor (fan) rotor. 

This condition, if not corrected, could 

reduce fan flutter margin and, in some cases, 

could lead to multiple fan blade failures, 

possibly resulting in an uncontained release 

of high energy debris with consequent 

damage to, and/or reduced control of, the 

aeroplane. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

considered the comments received. 

Request To Change Unsafe Condition 

Statement Wording 

RRD requested that we clarify the 

cause of fan blade flutter stated in the 

unsafe condition statement to include 

‘‘. . . affects the aerodynamic flutter 

margin causing subsequent multiple fan 

blade failure . . .’’. Fan blade flutter 

does not occur automatically. Reduction 

of fan flutter margin increases the risk 

of fan flutter potentially leading to fan 

blade cracking. 

We agree. We changed the unsafe 

condition statement to ‘‘This AD was 

prompted by excessive deterioration of 

the 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’’. 

Request To Change Applicability 

RRD requested that we change the 

scope of the AD to include Tay 650–15 

and Tay 651–54 engine models. The 

justification for this request is supported 

by European Aviation Safety Agency AD 

2013–0142, dated July 12, 2013 and 

RRD Alert Non-Modification Service 

Bulletin (NMSB) No. TAY–75–A1784, 

Revision 1, dated May 30, 2013. 

We partially agree. We disagree with 

adding the Tay 650–15 engine model 

because it is already in the AD. We 

agree with adding the Tay 651–54 

engine model to the applicability 

because it is included in RRD NMSB 

No. TAY–75–A1784, Revision 1, dated 

May 30, 2013. Additionally, we added 

the Tay 620–15 engine model to the 

applicability because the latest MCAI 

added it. We changed the applicability 

accordingly, which increased the costs 

of compliance. Further, we updated the 

paragraph number reference in 

Compliance paragraph (e)(2) of this AD 

to correspond to the revised NMSB. 

Conclusion 

We 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 determined that these changes will 

not significantly increase the economic 

burden on any operator or increase the 

scope of the AD. 

Costs of Compliance 

We estimate that this AD will affect 

about 78 engines of U.S. registry. We 

also estimate that it will take about 10 

hours per engine to comply with this 

AD. The average labor rate is $85 per 

hour. Required parts will cost about 

$153 per engine. Based on these figures, 

we estimate the cost of the AD on U.S. 

operators to be $78,234. 

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 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 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket.
