E7–11673 Filed 6–19–07; 8:45 am] airworthiness information (MCAI) originated 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: There are four ECS (environmental control system) grilles located in the flight deck side consoles. There have been occurrences where a grille has become detached during flight. There is a risk that a loose grille could foul the rudder pedals and interfere with rudder/ brake control resulting in an unsafe condition.

ACTION: Final rule. AGENCY: SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 The FAA is implementing a new process for streamlining the issuance of ADs related to MCAI. This streamlined process will allow us to adopt MCAI safety requirements in a more efficient manner and will reduce safety risks to the public. This process continues to follow all FAA AD issuance processes to meet legal, economic, Administrative Procedure Act, and Federal Register requirements. We also continue to meet our technical decision-making responsibilities to identify and correct unsafe conditions on U.S.-certificated products. This AD references the MCAI and related service information that we considered in forming the engineering basis to correct the unsafe condition. The AD contains text copied from the MCAI and for this reason might not follow our plain language principles. E:\FR\FM\20JNR1.SGM 20JNR1 Federal Register / Vol. 72, No. 118 / Wednesday, June 20, 2007 / Rules and Regulations 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 March 28, 2007 (72 FR 14500). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: There are four ECS (environmental control system) grilles located in the flight deck side consoles. There have been occurrences where a grille has become detached during flight. There is a risk that a loose grille could foul the rudder pedals and interfere with rudder/ brake control resulting in an unsafe condition. The unsafe condition is a rudder pedal restriction or jam, which could result in reduced controllability of the airplane. The MCAI requires modifying the grilles. You may obtain further information by examining the MCAI in the AD docket. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public. Conclusion We reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed. jlentini on PROD1PC65 with RULES Differences Between This AD and the MCAI or Service Information We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information. We might also have required different actions in this AD from those in the MCAI in order to follow our FAA policies. Any such differences are highlighted in a NOTE within the AD. Costs of Compliance We estimate that this AD will affect 10 products of U.S. registry. We also estimate that it will take about 3 workhours per product to comply with the basic requirements of this AD. The average labor rate is $80 per work-hour. Required parts will cost about $6,893 per product. Where the service information lists required parts costs that are covered under warranty, we VerDate Aug<31>2005 17:14 Jun 19, 2007 Jkt 211001 have assumed that there will be no charge for these parts. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $71,330, or $7,133 per product. 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://dms.dot.gov; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

ACTION: Final rule. AGENCY: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all Boeing Model 777 airplanes. This AD requires repetitive measurements of the freeplay of the right and left elevators, rudder, and rudder tab, and related investigative and corrective actions if necessary. This AD also requires repetitive lubrication of the elevator, rudder, and rudder tab components. This AD results from reports of freeplayinduced vibration of unbalanced control surfaces. Excessive freeplay of control surfaces can cause unacceptable airframe vibration during flight. The potential for vibration of the control surface should be avoided because the point of transition from vibration to divergent flutter is unknown. We are issuing this AD to prevent flutter, which can cause damage to the control surface structure and consequent loss of control of the airplane. DATES: This AD becomes effective July 25, 2007.

Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to all Boeing Model 777 airplanes. That NPRM was published in the Federal Register on October 3, 2006 (71 FR 58323). That NPRM proposed to require repetitive measurements of the freeplay of the right and left elevators, rudder, and rudder tab, and related investigative and corrective actions if necessary. That NPRM also proposed to require repetitive lubrication of the elevator, rudder, and rudder tab components. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comments received. Support for the NPRM Boeing and United Airlines support the contents of the NPRM. Request To Accomplish Repetitive Actions at the Later of the Compliance Times United Airlines requests that we revise the compliance times for the repetitive freeplay measurements and lubrication to specify doing those actions at the later of the proposed compliance times (i.e., whichever occurs later). Boeing Special Attention Service Bulletin 777–27–0062, dated July 18, 2006, recommends repeating the freeplay measurement at intervals of 12,000 flight hours or 36 months, whichever occurs first, and repeating the lubrication at intervals of 5,000 flight hours or 16 months, whichever occurs first.

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) originated 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:

    There are four ECS (environmental control system) grilles 
located in the flight deck side consoles. There have been 
occurrences where a grille has become detached during flight. There 
is a risk that a loose grille could foul the rudder pedals and 
interfere with rudder/brake control resulting in an unsafe 
condition.

The unsafe condition is a rudder pedal restriction or jam, which could 
result in reduced controllability of the airplane. We are issuing this 
AD to require actions to correct the unsafe condition on these 
products.

DATES: This AD becomes effective July 25, 2007.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of July 25, 
2007.

ADDRESSES: You may examine the AD docket on the Internet at http://

SUPPLEMENTARY INFORMATION:

Streamlined Issuance of AD

    The FAA is implementing a new process for streamlining the issuance 
of ADs related to MCAI. This streamlined process will allow us to adopt 
MCAI safety requirements in a more efficient manner and will reduce 
safety risks to the public. This process continues to follow all FAA AD 
issuance processes to meet legal, economic, Administrative Procedure 
Act, and Federal Register requirements. We also continue to meet our 
technical decision-making responsibilities to identify and correct 
unsafe conditions on U.S.-certificated products.
    This AD references the MCAI and related service information that we 
considered in forming the engineering basis to correct the unsafe 
condition. The AD contains text copied from the MCAI and for this 
reason might not follow our plain language principles.

[[Page 33855]]

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 March 28, 2007 (72 
FR 14500). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    There are four ECS (environmental control system) grilles 
located in the flight deck side consoles. There have been 
occurrences where a grille has become detached during flight. There 
is a risk that a loose grille could foul the rudder pedals and 
interfere with rudder/brake control resulting in an unsafe 
condition.

The unsafe condition is a rudder pedal restriction or jam, which could 
result in reduced controllability of the airplane. The MCAI requires 
modifying the grilles. You may obtain further information by examining 
the MCAI in the AD docket.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting the AD as proposed.

Differences Between This AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might also have required different actions in this AD from those 
in the MCAI in order to follow our FAA policies. Any such differences 
are highlighted in a NOTE within the AD.

Costs of Compliance

    We estimate that this AD will affect 10 products of U.S. registry. 
We also estimate that it will take about 3 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $80 per work-hour. Required parts will cost about $6,893 per 
product. Where the service information lists required parts costs that 
are covered under warranty, we have assumed that there will be no 
charge for these parts. As we do not control warranty coverage for 
affected parties, some parties may incur costs higher than estimated 
here. Based on these figures, we estimate the cost of this AD to the 
U.S. operators to be $71,330, or $7,133 per product.

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://
dms.dot.gov; or in person at the Docket Management Facility between 9 
a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD 
docket contains the NPRM, the regulatory evaluation, any comments 
received, and other information. The street address for the Docket 
Office (telephone (800) 647-5227) is in the ADDRESSES section. Comments 
will be available in the AD docket shortly after receipt.

RJ70A, 146-RJ85A, and 146-RJ100A airplanes; certificated in any 
category; which have modification HCM00674A embodied.

Reason

    (d) The mandatory continuing airworthiness information (MCAI) 
states:
    There are four ECS (environmental control system) grilles 
located in the flight deck side consoles. There have been 
occurrences where a grille has become detached during flight. There 
is a risk that a loose grille could foul the rudder pedals and 
interfere with rudder/brake control resulting in an unsafe 
condition.

The unsafe condition is a rudder pedal restriction or jam, which 
could result in reduced controllability of the airplane. The MCAI 
requires modifying the grilles.

Subject

    (e) Equipment/Furnishings.

Actions and Compliance

    (f) Within 6 months after the effective date of this AD, unless 
already done, carry out the modification of the ECS grilles as 
described in BAE Systems (Operations) Limited Modification Service 
Bulletin SB.25-495-

[[Page 33856]]
