[FR Doc. 05–17333 Filed 8–31–05; 8:45 am] BILLING CODE 4910–13–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2005–21595; Directorate Identifier 2002–NM–321–AD; Amendment 39–14245; AD 2005–18–05] RIN 2120–AA64 Airworthiness Directives; Bombardier Model CL–215–1A10 (Water Bomber), CL–215–6B11 (CL215T Variant), and CL–215–6B11 (CL415 Variant) Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. AGENCY: SUMMARY: The FAA is superseding an existing airworthiness directive (AD), which applies to certain Bombardier Model CL–215–1A10 and CL–215–6B11 series airplanes. That AD currently requires repetitive ultrasonic inspections to detect cracking of the lower caps of the wing front spar and rear spar, and corrective action if necessary. This new AD reduces the threshold to do the initial inspections and revises the repetitive inspection interval. This new AD also adds a repetitive ultrasonic inspection of the wing lower skin. This AD results from reports of cracks in the front and rear spar lower caps. We are issuing this AD to detect and correct cracking of the lower caps of the wing front spar and rear spar, which could result in reduced structural integrity of the airplane. VerDate Aug<18>2005 14:19 Aug 31, 2005 Jkt 205001 This AD becomes effective October 6, 2005. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of October 6, 2005. On March 4, 1998 (63 FR 7640, February 17, 1998), the Director of the Federal Register approved the incorporation by reference of Canadair Alert Service Bulletin 215–A454, Revision 1, dated May 25, 1995; and Canadair Alert Service Bulletin 215– A463, Revision 1, dated May 25, 1995.

SUPPLEMENTARY INFORMATION: DATES: Examining the Docket You may examine the 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 supersedes AD 98–04–08, amendment 39–10321 (63 FR 7640, February 17, 1998). The existing AD applies to certain Bombardier Model CL–215– 1A10 and CL–215–6B11 series airplanes. That NPRM was published in the Federal Register on June 22, 2005 (70 FR 36075). That NPRM proposed to continue to require repetitive ultrasonic inspections to detect cracking of the lower caps of the wing front spar and rear spar, and corrective action if necessary. That NPRM also proposed to require reducing the threshold in the existing AD for doing the initial inspections and revising the repetitive PO 00000 Frm 00011 Fmt 4700 Sfmt 4700 52009 inspection interval, and to add a repetitive ultrasonic inspection of the wing lower skin. Comments We provided the public the opportunity to participate in the development of this AD. No comments have been received on the NPRM or on the determination of the cost to the public. Explanation of Change in Applicability We have revised the applicability of the final rule to identify model designations as published in the most recent type certificate data sheet for the affected models. 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 affects about 3 airplanes of U.S. registry. The actions that are required by AD 98–04–08 and retained in this AD take about 16 work hours per airplane, at an average labor rate of $65 per work hour. Based on these figures, the estimated cost of the currently required actions is $1,040 per airplane, per inspection cycle. The new inspections required by this AD will take about 1 work hour per airplane, at an average labor rate of $65 per work hour. Based on these figures, the estimated cost of the new inspections specified in this AD for U.S. operators is $195 per inspection cycle, or $65 per airplane, per inspection cycle. 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 E:\FR\FM\01SER1.SGM 01SER1 52010 Federal Register / Vol. 70, No. 169 / Thursday, September 1, 2005 / Rules and Regulations 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.

Airplanes

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

ACTION: Final rule.

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

SUMMARY: The FAA is superseding an existing airworthiness directive 
(AD), which applies to certain Bombardier Model CL-215-1A10 and CL-215-
6B11 series airplanes. That AD currently requires repetitive ultrasonic 
inspections to detect cracking of the lower caps of the wing front spar 
and rear spar, and corrective action if necessary. This new AD reduces 
the threshold to do the initial inspections and revises the repetitive 
inspection interval. This new AD also adds a repetitive ultrasonic 
inspection of the wing lower skin. This AD results from reports of 
cracks in the front and rear spar lower caps. We are issuing this AD to 
detect and correct cracking of the lower caps of the wing front spar 
and rear spar, which could result in reduced structural integrity of 
the airplane.

DATES: This AD becomes effective October 6, 2005.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of October 6, 
2005.
    On March 4, 1998 (63 FR 7640, February 17, 1998), the Director of 
the Federal Register approved the incorporation by reference of 
Canadair Alert Service Bulletin 215-A454, Revision 1, dated May 25, 
1995; and Canadair Alert Service Bulletin 215-A463, Revision 1, dated 
May 25, 1995.

SUPPLEMENTARY INFORMATION:

Examining the Docket

    You may examine the 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 supersedes AD 98-04-08, amendment 39-
10321 (63 FR 7640, February 17, 1998). The existing AD applies to 
certain Bombardier Model CL-215-1A10 and CL-215-6B11 series airplanes. 
That NPRM was published in the Federal Register on June 22, 2005 (70 FR 
36075). That NPRM proposed to continue to require repetitive ultrasonic 
inspections to detect cracking of the lower caps of the wing front spar 
and rear spar, and corrective action if necessary. That NPRM also 
proposed to require reducing the threshold in the existing AD for doing 
the initial inspections and revising the repetitive inspection 
interval, and to add a repetitive ultrasonic inspection of the wing 
lower skin.

Comments

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

Explanation of Change in Applicability

    We have revised the applicability of the final rule to identify 
model designations as published in the most recent type certificate 
data sheet for the affected models.

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 affects about 3 airplanes of U.S. registry.
    The actions that are required by AD 98-04-08 and retained in this 
AD take about 16 work hours per airplane, at an average labor rate of 
$65 per work hour. Based on these figures, the estimated cost of the 
currently required actions is $1,040 per airplane, per inspection 
cycle.
    The new inspections required by this AD will take about 1 work hour 
per airplane, at an average labor rate of $65 per work hour. Based on 
these figures, the estimated cost of the new inspections specified in 
this AD for U.S. operators is $195 per inspection cycle, or $65 per 
airplane, per inspection cycle.

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

[[Page 52010]]

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.
