AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments; revision. 

SUMMARY: The FAA is revising an 

existing airworthiness directive (AD) for 

the products listed above. This AD 

revision results from the need to correct 

the applicability paragraph of that AD, 

and from mandatory continuing 

airworthiness information (MCAI) 

issued by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

Strip results from some of the engines 

listed in the applicability section of this AD 

revealed excessively corroded low-pressure 

turbine disks stage 2 and stage 3. The 

corrosion is considered to be caused by the 

environment in which these engines are 

operated. Following a life assessment based 

on the strip findings it is concluded that 

inspections for corrosion attack are required. 

The action specified by this European 

Aviation Safety Agency (EASA) AD 2008– 

0122 was intended to avoid a failure of a lowpressure turbine disk stage 2 or stage 3 due 

to potential corrosion problems which could 

result in uncontained engine failure and 

damage to the airplane. It has been later 

realized that the same unsafe condition could 

potentially occur on more serial numbers for 

the Tay 650–15 engines and on the Tay 651– 

54 engines. This AD, superseding EASA AD 

2008–0122, retaining its requirements, is 

therefore issued to expand the Applicability 

in adding further engine serial numbers for 

the Tay 650–15 engines and in adding the 

Tay 651–54 engines. 

We are issuing this AD to detect 

corrosion that could cause the stage 2 or 

stage 3 disk of the LP turbine to fail, 

uncontained engine failure, and damage 

to the airplane. 

DATES: This AD becomes effective 

November 18, 2010. 

We must receive comments on this 

AD by December 3, 2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of RRD Alert Service Bulletin No. TAY– 

72–A1524, Revision 3, dated March 24, 

2010, as of September 27, 2010 (75 FR

SUPPLEMENTARY INFORMATION: 

Discussion 

On August 23, 2010, we published AD 

2010–17–12, Amendment 39–16404, in 

the Federal Register (75 FR 51651). That 

AD is applicable to RRD models Tay 

650–15 and Tay 651–54 turbofan 

engines. We discovered that the 

applicability paragraph of that AD is in 

error. This AD revision corrects that 

applicability paragraph. The 

requirements of that AD remain the 

same in this AD revision. 

FAA’s Determination and Requirements 

of This AD 

This product has been approved by 

the aviation authority of the United 

Kingdom, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the United 

Kingdom, they have notified us of the 

unsafe condition described in the MCAI. 

We are issuing this AD because we 

evaluated all information provided by 

the European Aviation Safety Agency 

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 this AD revision reduces 

the applicability, and the impact on the 

affected U.S. registered fleet remains 

unchanged. Therefore, we determined 

that notice and opportunity for public 

comment before issuing this AD are 

impracticable and that good cause exists 

for making this amendment effective in 

fewer 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–2007–0037; 

Directorate Identifier 2007–NE–41–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,

67612 Federal Register / Vol. 75, No. 212 / Wednesday, November 3, 2010 / Rules and Regulations 

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); 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.

Reason 

(d) This AD revision results from: 

(1) The need to correct the applicability 

paragraph of AD 2010–17–12; and 

(2) From mandatory continuing 

airworthiness information (MCAI) issued by 

an aviation authority of another country to 

identify and correct an unsafe condition on 

an aviation product. The MCAI states: 

(3) Strip results from some of the engines 

listed in the applicability section of this AD 

revealed excessively corroded low-pressure 

turbine disks stage 2 and stage 3. The 

corrosion is considered to be caused by the 

environment in which these engines are 

operated. Following a life assessment based 

on the strip findings it is concluded that 

inspections for corrosion attack are required. 

The action specified by this European 

Aviation Safety Agency (EASA) AD 2008– 

0122 was intended to avoid a failure of a lowpressure turbine disk stage 2 or stage 3 due 

to potential corrosion problems which could 

result in uncontained engine failure and 

damage to the airplane. It has been later 

realized that the same unsafe condition could 

potentially occur on more serial numbers for 

the Tay 650–15 engines and on the Tay 651– 

54 engines. This AD, superseding EASA AD 

2008–0122, retaining its requirements, is 

therefore issued to expand the Applicability 

in adding further engine serial numbers for 

the Tay 650–15 engines and in adding the 

Tay 651–54 engines. 

We are issuing this AD to detect corrosion 

that could cause the stage 2 or stage 3 disk 

of the LP turbine to fail, uncontained engine 

failure, and damage to the airplane. 

Actions and Compliance 

(e) Unless already done, do the following 

actions. 

(1) Prior to accumulating 11,700 flight 

cycles (FC) since new of disk life, and 

thereafter at intervals not exceeding 11,700 

FC of disk life, inspect the LP turbine disks 

stage 2 and stage 3 for corrosion using RRD 

Alert Service Bulletin (ASB) No. TAY–72– 

A1524, Revision 3, dated March 24, 2010. 

(2) For engines with disk life that already 

exceed 11,700 FC on the effective date of this 

AD, perform the inspection within 90 days 

after the effective date of this AD. 

(3) When, during any of the inspections as 

required by paragraphs (e)(1) and (e)(2) of 

this AD, corrosion is found, replace the 

affected parts. RRD TAY 650 Engine 

Manual—E–TAY–3RR, Tasks 72–52–23–200– 

000 and 72–52–24–200–000, and RRD TAY 

651 Engine Manual—E–TAY–5RR, Tasks 

72–52–23–200–000 and 72–52–24–200–000, 

contain guidance on performing the 

inspection for corrosion and rejection 

criteria. 

Previous Credit 

(f) Initial inspections done before the 

effective date of this AD on LP turbine disks 

stage 2 and stage 3 listed in Table 1 and 

Table 2 of this AD using RRD ASB No. TAY– 

72–A1524, Revision 1, dated September 1, 

2006, or Revision 2, dated June 13, 2008, 

comply with the initial inspection 

requirements specified in this AD. 

Alternative Methods of Compliance 

(AMOCs) 

(g) The Manager, Engine Certification 

Office, FAA, has the authority to approve 

AMOCs for this AD, if requested using the 

procedures found in 14 CFR 39.19.

ACTION: Final rule. 

SUMMARY: We are superseding an 

existing airworthiness directive (AD) for 

the products listed above. That AD 

currently requires removing certain 

propeller hubs from service at new, 

reduced life limits and eddy current 

inspections (ECIs) of the propeller hub. 

This new AD requires removing certain 

propeller hubs from service before they 

exceed 6,000 hours time-since-new 

(TSN). This AD was prompted by a 

report of a crack in a propeller hub. We 

are issuing this AD to prevent cracked 

propeller hubs, which could cause 

failure of the propeller hub, blade 

separation, and loss of control of the 

airplane. 

DATES: This AD is effective December 8, 

2010.
