AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD results 

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: 

As a result of a change in the low-cycle 

fatigue lifing methodology for the IMI 834 

material, the recommended service life of 

certain PW305A and PW305B Impellers has 

been reduced, as published in the 

Airworthiness Limitations (AWL) section of 

Engine Maintenance Manual (EMM). 

The in-service life of impellers P/N 

30B2185, 30B2486 and 30B2858–01 has been 

reduced from 12,000 to 7,000 cycles; and of 

P/N 30B4565–01 from 8,500 to 7,000 cycles. 

We are issuing this AD to prevent 

failure of the impeller, which could 

result in an uncontained event and 

possible damage to the airplane.

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. That 

NPRM was published in the Federal 

Register on August 19, 2010 (75 FR 

51187). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

As a result of a change in the low-cycle 

fatigue lifing methodology for the IMI 834 

material, the recommended service life of 

certain PW305A and PW305B Impellers has 

been reduced, as published in the 

Airworthiness Limitations (AWL) section of 

Engine Maintenance Manual (EMM). 

The in-service life of impellers P/N 

30B2185, 30B2486 and 30B2858–01 has been 

reduced from 12,000 to 7,000 cycles; and of 

P/N 30B4565–01 from 8,500 to 7,000 cycles. 

This Airworthiness Directive (AD) is 

issued to mandate the incorporation of the 

revised in-service life limits for the affected 

impellers, in the AWL section of EMM, as 

introduced by Temporary Revision (TR) 

AL–8. 

Within 30 days from the effective date of 

this AD, update AWL section of your PW305 

EMM P/N 30B1402, to incorporate TR AL–8 

for compliance with the revised in-service 

limits for the affected Impellers, installed on 

PW305A and PW305B engine. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

considered the comment received. 

Request To Establish an Ending Engine 

Serial Number Applicability 

One commenter, Bombardier—Learjet, 

asked us to establish an ending engine 

serial number (S/N) applicability for the 

proposed AD. The commenter said that 

any engine from S/N CA0651 forward 

will be linked to the updated engine 

maintenance manual (EMM) with the 

7,000 cycle exducer life limit. Therefore, 

engines that have entered or will enter 

service with the appropriate 

Airworthiness Limitations already 

included in their EMM, will not be 

subject to this unsafe condition. To 

leave the AD applicability open-ended, 

will cause hours of unnecessary review 

and logbook entries for original 

equipment manufacturers (OEMs) and 

operators of engines that do not have an 

unsafe condition. 

We don’t agree. Because there are no 

mandatory links between the engine 

S/N and the EMM, there is no guarantee 

the EMM will stay with a particular 

engine S/N. Also, because the proposed 

AD is a onetime requirement to reduce 

the life limit for the exducer in the 

Airworthiness Limitations Section, the 

proposed AD won’t cause hours of 

unnecessary review and logbook entries 

for OEMs and operators of engines. We 

didn’t change the proposed AD. 

Conclusion 

We reviewed the available data, 

including the comment received, and 

determined that air safety and the 

public interest require adopting the AD 

as proposed. 

Costs of Compliance 

Based on the service information, we 

estimate that this AD will affect about 

114 products of U.S. registry. We also 

estimate that it will take 0 work-hours 

per product to comply with this AD. 

The average labor rate is $85 per workhour. Required parts will cost about 

$54,288 per product. Based on these 

figures, we estimate the cost of the AD 

on U.S. operators to be $6,188,832. Our 

cost estimate is exclusive of possible 

warranty coverage. 

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. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Operations office between 9 a.m. 

and 5 p.m., Monday through Friday, 

except Federal holidays. The AD docket 

contains this AD, the regulatory 

evaluation, any comments received, and 

other information. The street address for 

the Docket Operations office (phone 

(800) 647–5527) is provided in the 

ADDRESSES section. Comments will be 

available in the AD docket shortly after 

receipt.

(NOAA), Department of Commerce 

(DOC). 

ACTION: Final rule. 

SUMMARY: NOAA is amending the 

regulations for the Florida Keys 

National Marine Sanctuary (FKNMS or 

sanctuary) by eliminating the exemption 

that allows discharges from within the 

boundary of the sanctuary of 

biodegradable effluent incidental to 

vessel use and generated by marine 

sanitation devices (MSDs) approved 

under the Clean Water Act (CWA), and 

by requiring that MSDs be secured to 

prevent discharges of treated and 

untreated sewage. This action builds 

upon the Environmental Protection 

Agency’s creation of a No Discharge 

Zone (NDZ) for the state waters of the 

FKNMS, and will help protect the 

Florida Keys ecosystem from potentially 

harmful vessel sewage discharges. An 

environmental assessment has been 

prepared for this action pursuant to the 

National Environmental Policy Act. The 

environmental assessment includes a 

Finding of No Significant Impact 

(FONSI) regarding the impacts of this 

rulemaking. 

DATES: These regulations are effective 

on December 27, 2010. 

ADDRESSES: A copy of the 

environmental assessment, which 

includes the FONSI, described in this 

rule is available upon request to Sean 

Morton, Sanctuary Superintendent,

I. Statutory and Regulatory Background 

The National Marine Sanctuaries Act 

(NMSA) (16 U.S.C. 1431 et seq.) 

authorizes the Secretary of Commerce to 

designate and protect as national marine 

sanctuaries areas of the marine 

environment with special national 

significance due to their conservation, 

recreational, ecological, historical, 

scientific, cultural, archeological, 

educational, or esthetic qualities. 

Management of national marine 

sanctuaries has been delegated by the 

Secretary of Commerce to NOAA’s 

Office of National Marine Sanctuaries. 

The primary objective of the NMSA is 

to protect marine resources, such as 

coral reefs, sunken historical vessels, or 

unique habitats. 

The FKNMS was designated by 

Congress in 1990 through the Florida 

Keys National Marine Sanctuary 

Protection Act (FKNMSPA, Pub. L. 101– 

605) and extends approximately 220 

nautical miles southwest from the 

southern tip of the Florida peninsula. 

The sanctuary’s marine ecosystem 

supports over 6,000 species of plants, 

fishes and invertebrates, including the 

Nation’s only living coral reef that lies 

adjacent to the continent. The area 

includes one of the largest seagrass
