ACTION: Final rule. AGENCY: jlentini on PROD1PC65 with RULES SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain BAE Systems (Operations) Limited Model BAe 146 airplanes. This AD requires repetitive inspections to measure the depth of chafing or scoring in the skin along the full length of the wing-to-fuselage fairing from forward to aft ends at the contact between the seal and fuselage, and related investigative/ corrective actions if necessary. This AD results from a report of chafing in this area. We are issuing this AD to detect and correct such chafing or scoring, which could result in reduced structural integrity of the fuselage. DATES: This AD becomes effective November 2, 2006. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of November 2, 2006. ADDRESSES: You may examine the AD docket on the Internet at https:// dms.dot.gov or in person at the Docket Management Facility, U.S. Department of Transportation, 400 Seventh Street, SW., Nassif Building, Room PL–401, Washington, DC. Contact British Aerospace Regional Aircraft American Support, 13850 Mclearen Road, Herndon, Virginia 20171, for service information identified in this AD. VerDate Aug<31>2005 17:21 Sep 27, 2006 Jkt 208001 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 supplemental notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to certain BAE Systems (Operations) Limited Model BAe 146 airplanes. That supplemental NPRM was published in the Federal Register on April 5, 2006 (71 FR 17037). That supplemental NPRM proposed to require repetitive inspections to measure the depth of chafing or scoring in the skin along the full length of the wing-to-fuselage fairing from forward to aft ends at the contact between the seal and fuselage, and related investigative/ corrective actions if necessary. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comment we received on the supplemental NPRM. Request for Revised Compliance Time BAE notes that corresponding British airworthiness directive G–2005–0020, dated July 6, 2005, allows an additional 4,000 flight cycles before previously inspected airplanes must be reinspected. But paragraph (f) of the supplemental NPRM would require all airplanes to be inspected before the airplane accumulates 1,000 total flight cycles, or within a grace period of 500 flight cycles, without any provision for an extended compliance time for airplanes previously inspected in accordance with both BAE Systems (Operations) Limited Inspection Service Bulletins ISB.53–005, Revision 2, dated PO 00000 Frm 00007 Fmt 4700 Sfmt 4700 56859 February 16, 2005, and ISB.53–067, Revision 3, dated June 27, 2005. BAE adds that there are no airplanes in service with fewer than 1,000 total flight cycles. We infer that the commenter requests that we revise the supplemental NPRM. We agree. We have revised paragraph (f) to allow the deferral of certain corrective actions under specific conditions outlined in the service bulletins, as provided in new paragraph (h) in this AD. Additional Changes to Supplemental NPRM The supplemental NPRM specified that all actions including corrective actions would be required at the times specified in BAE Systems (Operations) Limited Inspection Service Bulletins ISB.53–005 and ISB.53–067. Our intent was to match the specifications of the service bulletins, which allow deferred corrective action only under certain conditions. To clarify the required compliance times of this AD, we have added new paragraph (h) to explicitly require corrective actions before further flight, except when repair may be deferred under the specific conditions noted in the service bulletins. Paragraph (g) of the supplemental NPRM specified making repairs using a method approved by either the FAA or the Civil Aviation Authority, which is the airworthiness authority for the United Kingdom. The European Aviation Safety Agency (EASA) has assumed responsibility for the airplane model subject to this AD. Therefore, we have revised paragraph (g) of this AD to specify making repairs using a method approved by the FAA, the CAA (or its delegated agent), or the EASA (or its delegated agent). Conclusion We have carefully reviewed the available data, including the comments received, and determined that air safety and the public interest require adopting the AD with the changes described previously. We have determined that these changes will neither increase the economic burden on any operator nor increase the scope of the AD. Costs of Compliance The following table provides the estimated costs for U.S. operators to comply with this AD.

Airworthiness Directives; BAE Systems (Operations) Limited Model 
BAe 146 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 BAE Systems (Operations) Limited Model BAe 146 airplanes. This 
AD requires repetitive inspections to measure the depth of chafing or 
scoring in the skin along the full length of the wing-to-fuselage 
fairing from forward to aft ends at the contact between the seal and 
fuselage, and related investigative/corrective actions if necessary. 
This AD results from a report of chafing in this area. We are issuing 
this AD to detect and correct such chafing or scoring, which could 
result in reduced structural integrity of the fuselage.

DATES: This AD becomes effective November 2, 2006.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of November 2, 
2006.

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

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 supplemental notice of proposed rulemaking (NPRM) 
to amend 14 CFR part 39 to include an AD that would apply to certain 
BAE Systems (Operations) Limited Model BAe 146 airplanes. That 
supplemental NPRM was published in the Federal Register on April 5, 
2006 (71 FR 17037). That supplemental NPRM proposed to require 
repetitive inspections to measure the depth of chafing or scoring in 
the skin along the full length of the wing-to-fuselage fairing from 
forward to aft ends at the contact between the seal and fuselage, and 
related investigative/corrective actions if necessary.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comment we received on 
the supplemental NPRM.

Request for Revised Compliance Time

    BAE notes that corresponding British airworthiness directive G-
2005-0020, dated July 6, 2005, allows an additional 4,000 flight cycles 
before previously inspected airplanes must be reinspected. But 
paragraph (f) of the supplemental NPRM would require all airplanes to 
be inspected before the airplane accumulates 1,000 total flight cycles, 
or within a grace period of 500 flight cycles, without any provision 
for an extended compliance time for airplanes previously inspected in 
accordance with both BAE Systems (Operations) Limited Inspection 
Service Bulletins ISB.53-005, Revision 2, dated February 16, 2005, and 
ISB.53-067, Revision 3, dated June 27, 2005. BAE adds that there are no 
airplanes in service with fewer than 1,000 total flight cycles.
    We infer that the commenter requests that we revise the 
supplemental NPRM. We agree. We have revised paragraph (f) to allow the 
deferral of certain corrective actions under specific conditions 
outlined in the service bulletins, as provided in new paragraph (h) in 
this AD.

Additional Changes to Supplemental NPRM

    The supplemental NPRM specified that all actions including 
corrective actions would be required at the times specified in BAE 
Systems (Operations) Limited Inspection Service Bulletins ISB.53-005 
and ISB.53-067. Our intent was to match the specifications of the 
service bulletins, which allow deferred corrective action only under 
certain conditions. To clarify the required compliance times of this 
AD, we have added new paragraph (h) to explicitly require corrective 
actions before further flight, except when repair may be deferred under 
the specific conditions noted in the service bulletins.
    Paragraph (g) of the supplemental NPRM specified making repairs 
using a method approved by either the FAA or the Civil Aviation 
Authority, which is the airworthiness authority for the United Kingdom. 
The European Aviation Safety Agency (EASA) has assumed responsibility 
for the airplane model subject to this AD. Therefore, we have revised 
paragraph (g) of this AD to specify making repairs using a method 
approved by the FAA, the CAA (or its delegated agent), or the EASA (or 
its delegated agent).

Conclusion

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

Costs of Compliance

to comply with this AD.

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.

    (b) None.

Applicability

    (c) This AD applies to BAE Systems (Operations) Limited Model 
BAe 146-100A, -200A, and -300A series airplanes, certificated in any 
category, on which Modification HCM00301A or B has been done, and on 
which Modification HCM01698A has not been done.

Unsafe Condition

    (d) This AD results from a report of chafing along the seal/
fuselage contact area under the wing-to-fuselage fairing access 
panels on both sides of the fuselage. We are issuing this AD to 
detect and correct such chafing or scoring in this area, which could 
result in reduced structural integrity of the fuselage.

Compliance

    (e) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the 
actions have already been done.

Inspection

    (f) Inspect, using a dial test indicator, to measure the depth 
of any chafing or scoring in the skin along the full length of the 
wing-to-fuselage fairing from forward to aft ends at the point of 
contact between the seal and fuselage on both sides of the fuselage, 
and do applicable related investigative/corrective actions in 
accordance with the Accomplishment Instructions of BAE Systems 
(Operations) Limited Inspection Service Bulletins ISB.53-005, 
Revision 2, dated February 16, 2004; and ISB.53-067, Revision 3, 
dated June 27, 2005; except as required by paragraph (g) of this AD. 
Do the inspection before the airplane accumulates 1,000 total flight 
cycles, or within 500 flight cycles after the effective date of this 
AD, whichever occurs later. Do related investigative/corrective 
actions and repeat the inspection to measure the chafing/scoring at 
the times specified in the service bulletins, as applicable, except 
as required in paragraph (h) of this AD.
