Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to certain Saab Model SAAB 2000 airplanes. That NPRM was published in the Federal Register on September 1, 2005 (70 FR 52041). That NPRM proposed to require modifying the manual feather-and-unfeather system for the propellers to make the design of the system more robust. Comments We provided the public the opportunity to participate in the development of this AD. We received no comments on the NPRM or on the determination of the cost to the public. Clarification of Alternative Method of Compliance (AMOC) Paragraph We have revised this action to clarify the appropriate procedure for notifying the principal inspector before using any approved AMOC on any airplane to which the AMOC applies. Conclusion We have carefully reviewed the available data, and determined that air safety and the public interest require adopting the AD with the change described previously. We have determined that this change will neither increase the economic burden on any operator nor increase the scope of the AD. Costs of Compliance This AD will affect about 3 airplanes of U.S. registry. The actions will take about 50 work hours per airplane, at an average labor rate of $65 per work hour. Required parts will cost about $13,571 per airplane. Based on these figures, the estimated cost of the AD for U.S. operators is $50,463, or $16,821 per airplane. 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, VerDate Aug<31>2005 15:39 Nov 10, 2005 Jkt 208001 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 have 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.

ACTION: Final rule. AGENCY: SUMMARY: The FAA is superseding an existing airworthiness directive (AD), which applies to certain Airbus Model A319–100, A320–200, and A321–100 and –200 series airplanes. That AD currently requires modification of the telescopic girt bar of the escape slide/ raft assembly, and follow-on actions. This new AD requires a new modification of the telescopic girt bar and the installation of placards on the modified girt bars, which terminates the repetitive functional tests required by the existing AD. This AD results from development of a new, improved modification. We are issuing this AD to prevent failure of the escape slide/raft to deploy correctly, which could result in the slide being unusable during an emergency evacuation and consequent injury to passengers or airplane crewmembers.

Discussion The FAA issued a supplemental notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that supersedes AD 2001–16–14, amendment 39–12383 (66 FR 42939, August 16, 2001). The existing AD applies to certain Airbus Model A319, A320, and A321 series airplanes. That supplemental NPRM was published in the Federal Register on July 21, 2005 (70 FR 42005). That supplemental NPRM proposed to mandate the installation of placards on the modified girt bars, which terminates the repetitive functional tests required by the existing AD. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the additional comment that has been received on the supplemental NPRM. The commenter supports the supplemental NPRM.

Conclusion We have carefully reviewed the available data, including the comment that has been received, and determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance This AD will affect about 517 airplanes of U.S. registry. The modification that is required by AD 2001–16–14 and retained in this AD takes about 7 work hours per airplane, at an average labor rate of $65 per work hour. The cost of required parts is negligible. Based on these figures, the estimated cost of the currently required modification for U.S. operators is $235,235, or $455 per airplane. The functional test that is required by AD 2001–16–14 and retained in this AD takes about 1 work hour per airplane, at an average labor rate of $65 per work hour. Based on these figures, the cost impact of the currently required functional test for U.S. operators is $33,605, or $65 per airplane, per test cycle. For airplanes that have not been modified in accordance with AD 2001– 16–14: The new modification (including the new placard installation) takes about 17 work hours per airplane, at an average labor rate of $65 per work hour. Required parts cost about $5,130 per airplane. Based on these figures, the estimated cost of the new modification specified in this AD is $6,235 per airplane. For airplanes that have been modified in accordance with AD 2001–16–14: The new modification (including the new placard installation) takes about 21 work hours per airplane, at an average labor rate of $65 per work hour. Required parts cost about $5,130 per airplane. Based on these figures, the estimated cost of the new modification specified in this AD is $6,495 per airplane.

Airworthiness Directives; Saab Model SAAB 2000 Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Saab Model SAAB 2000 airplanes. This AD requires modifying the 
manual feather-and-unfeather system for the propellers to make the 
design of the system more robust. This AD results from reports of in-
flight engine shutdown caused by uncommanded operation of the feather 
pump of the propeller. We are issuing this AD to prevent uncommanded 
feathering of the propeller, which could result in the shutdown of an 
engine during flight and consequent reduced controllability of the 
airplane.

DATES: This AD becomes effective December 19, 2005.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of December 19, 
2005.

Examining the Docket

    You may examine the airworthiness directive (AD) docket on the 
Internet at https://dms.dot.gov or in person at the Docket Management 
Facility office between 9 a.m. and 5 p.m., Monday through Friday, 
except Federal holidays. The Docket Management Facility office 
(telephone (800) 647-5227) is located on the plaza level of the Nassif 
Building at the street address stated in the ADDRESSES section.

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that would apply to certain Saab Model 
SAAB 2000 airplanes. That NPRM was published in the Federal Register on 
September 1, 2005 (70 FR 52041). That NPRM proposed to require 
modifying the manual feather-and-unfeather system for the propellers to 
make the design of the system more robust.

Comments

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

Clarification of Alternative Method of Compliance (AMOC) Paragraph

    We have revised this action to clarify the appropriate procedure 
for notifying the principal inspector before using any approved AMOC on 
any airplane to which the AMOC applies.

Conclusion

    We have carefully reviewed the available data, and determined that 
air safety and the public interest require adopting the AD with the 
change described previously. We have determined that this change will 
neither increase the economic burden on any operator nor increase the 
scope of the AD.

Costs of Compliance

    This AD will affect about 3 airplanes of U.S. registry. The actions 
will take about 50 work hours per airplane, at an average labor rate of 
$65 per work hour. Required parts will cost about $13,571 per airplane. 
Based on these figures, the estimated cost of the AD for U.S. operators 
is $50,463, or $16,821 per airplane.

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 have 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 that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866;
    (2) Is not a ``significant rule'' under 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. See the ADDRESSES 
section for a location to examine the regulatory evaluation.
