Adoption of the Amendment 

■ Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 14 CFR part 39 as 

follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new AD: 

2009–07–01 Rolls-Royce Deutschland Ltd & 

Co KG (formerly BMW Rolls-Royce 

GmbH, formerly BMW Rolls-Royce Aero 

Engines): Amendment 39–15860. Docket 

No. FAA–2008–0224; Directorate 

Identifier 2007-NE–44-AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective April 27, 2009. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Rolls-Royce 

Deutschland Ltd & Co KG (RRD) BR700– 

715A1–30, BR700–715B1–30, and BR700– 

715C1–30 turbofan engines. These engines 

are installed on, but not limited to, 

McDonnell Douglas Model 717–200 

airplanes. 

Reason 

(d) It is necessary to change the limits of 

the High Pressure (HP) Turbine Stage 1 and 

Stage 2 Rotor Discs. The maximum approved 

life of these discs is decreased for all flight 

missions. 

This Emergency Airworthiness Directive 

(EAD) has been raised to instruct mandatory 

decreased maximum approved lives in the 

BR715 Time Limits Manual (TLM) T–715– 

3BR for the HP Turbine Stage 1 Rotor Disc 

for both Part No. BRH20130 and Part No. 

BRH20131 and of the High Pressure (HP) 

Turbine Stage 2 Rotor Disc for both Part No. 

BRH19423 and Part No. BRH19427 for all 

flight missions. The life limits are decreased 

by the same proportion for all flight missions, 

thus back to birth pro-rata calculations due 

to the life limit changes are not necessary. 

We are issuing this AD to prevent rotating 

parts that may have exceeded their low-cycle 

fatigue life limits from failing, which could 

result in uncontained engine failure and 

subsequent damage to the airplane. 

Actions and Compliance 

(e) No later than 30 days after the effective 

date of this AD the following mandatory 

actions need to be completed for each 

individual BR700–715 HP Turbine Stage 1 

Rotor Disc for both Part No. BRH20130 and 

Part No. BRH20131 and High Pressure (HP) 

Turbine Stage 2 Rotor Disc for both Part No. 

BRH19423 and Part No. BRH19427 installed 

in a BR700–715A1–30, B1–30 or C1–30 

engine: 

(1) Identify the mandatory decreased 

maximum approved life for the HP Turbine 

Stage 1 and Stage 2 Rotor Discs listed in the

National Marine Sanctuary 

Regulations; Notice of Effective Date 

AGENCY: Office of National Marine 

Sanctuaries (ONMS), National Oceanic 

and Atmospheric Administration 

(NOAA), Department of Commerce 

(DOC). 

ACTION: Notice of effective date. 

SUMMARY: NOAA published final 

revised management plans and revised 

regulations for the Gulf of the 

Farallones, Cordell Bank, and Monterey 

Bay national marine sanctuaries 

(GFNMS, CBNMS, and MBNMS 

respectively) on November 20, 2008 (73 

FR 70488). Under the National Marine 

Sanctuaries Act, the final regulations 

would automatically take effect after 45 

days of continuous session of Congress 

beginning from November 20, 2008. 

(Given the break in the 110th Congress, 

the period was reset and began again 

with the 111th Congress. For purposes 

of this action, the 45 days of continuous 

session of Congress ended on March 9, 

2009.) The period allows a governor for 

a state affected by modified term(s) of 

designation to certify to the Secretary of 

Commerce (Secretary) whether any of 

the modified terms of designation are 

unacceptable, and if such a term is 

certified as unacceptable, it does not 

take effect in the area of the national 

marine sanctuary lying within the 

seaward boundary of the State. During 

the 45-day period, the Governor of 

California sent a letter to the Secretary 

conditionally objecting to certain 

provisions of the regulations within 

state waters of California. The Governor 

conditionally objected to the portions of 

the regulations that would have 

prohibited the introduction of 

introduced species in state waters of the 

GFNMS and MBNMS. Through this 

notice, NOAA is announcing the 

regulations for the CBNMS and GFNMS 

became effective on March 9, 2009 in 

their entirety; and the regulations for the 

MBNMS also became effective on March 

9, 2009, except the one prohibiting the 

introduction of introduced species in 

the state waters of MBNMS; and it will 

initiate a process to consider making the 

Governor’s requested changes to the 

introduced species regulation in 

GFNMS. 

DATES: The regulations published on 

November 20, 2008 (73 FR 70488) are 

effective March 19, 2009 and applicable 

on March 9, 2009.

Armor, NOAA Office of National Marine 

Sanctuaries, 301–713–7234. 

SUPPLEMENTARY INFORMATION: 

Background 

NOAA published final revised 

management plans and revised 

regulations for the GFNMS, CBNMS, 

and MBNMS on November 20, 2008 (73 

FR 70488). Section 304(b) of the NMSA 

provides the Governor with 45 days of 

continuous session of Congress 

(beginning on the day on which the 

final regulations were published) to 

review the terms of designation (or 

changes thereto). After this period the 

regulations would become final and take 

effect, except that any new or modified 

term of designation the Governor 

certified as unacceptable would not take 

effect in state waters of the sanctuary. 

Governor’s Objection to the Regulations 

of Introduced Species 

NOAA’s regulations would have, 

among other things, prohibited the 

introduction of introduced species into 

the sanctuaries with exceptions for 

striped bass caught and released during 

fishing and current state-permitted 

mariculture activities in Tomales Bay 

(part of GFNMS). The prohibition 

against introducing species is intended 

to prevent injury to sanctuary resources 

and qualities, to protect the biodiversity 

of sanctuary ecosystems, and to preserve 

the native functional aspects of 

sanctuary ecosystems, which are put at 

risk by introduced species. Introduced 

species may become a new form of 

predator, competitor, disturber, parasite, 

or disease that can have devastating 

effects upon ecosystems. For example, 

introduced species impacts on native 

coastal marine species of the GFNMS, 

MBNMS, and CBNMS could include: 

replacement of a functionally similar 

native species through competition; 

reduction in abundance or elimination 

of an entire population of a native 

species, which can affect native species 

richness; inhibition of normal growth or 

increased mortality of the host and 

associated species; increased intra- or 

interspecies competition with native 

species; creation or alteration of original 

substrate and habitat; hybridization 

with native species; and direct or 

indirect toxicity (e.g., toxic diatoms). 

Changes in species interactions can lead 

to disrupted nutrient cycles and altered 

energy flows that ripple with 

unpredictable results through an entire 

ecosystem. Introduced species may also 

pose threats to endangered species and 

native species diversity. 

On December 23, 2008, the Governor 

of California sent a letter to the 

Secretary of Commerce conditionally 

objecting to the revised terms of 

designation that would have allowed 

NOAA to issue regulations prohibiting 

the introduction of introduced species 

in the state waters of the GFNMS and 

MBNMS.1 The Governor conditioned 

his objection to the revised terms of 

designation on NOAA’s willingness and 

ability to modify these regulations to 

exempt all state-permitted aquaculture 

activities in MBNMS and GFNMS and 

research involving the introduction of 

introduced species into MBNMS. 

After receiving the letter from the 

Governor, NOAA worked with the 

California Resources Agency and the 

California Department of Fish and Game 

to find a mutually agreeable solution to 

the Governor’s concerns. In a letter 

dated March 2, 2009, the Acting 

Secretary of Commerce, Otto J. Wolff, 

replied to the Governor by: (1) Offering 

to immediately propose exemptions for 

introduced species cultivated in stateVerDate Nov<24>2008 15:22 Mar 20, 2009 Jkt 217001 PO 00000 Frm 00038 Fmt 4700 Sfmt 4700 E:\FR\FM\23MRR1.SGM 23MRR1
