ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of comment period. cchase on PROD1PC60 with PROPOSALS AGENCY: SUMMARY: The FAA is revising an earlier NPRM for an airworthiness directive (AD) that applies to certain BAE Systems (Operations) Limited Model BAe 146 airplanes. The original NPRM would have required 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. The original NPRM resulted from a report of chafing in this area. This action revises the original NPRM by removing certain credit for prior accomplishment of proposed requirements. We are proposing this supplemental NPRM to detect and correct such chafing or scoring, which could result in reduced structural integrity of the fuselage. DATES: We must receive comments on this supplemental NPRM by May 1, 2006.

Discussion We proposed to amend 14 CFR part 39 with a notice of proposed rulemaking (NPRM) for an airworthiness directive (AD) (the ‘‘original NPRM’’). The original NPRM applies to certain BAE Systems (Operations) Limited Model BAe 146 airplanes. The original NPRM was published in the Federal Register on November 15, 2005 (70 FR 69286). The original NPRM proposed to require repetitive inspections to measure the depth of chafing or scoring in the skin along the full length of the wing-tofuselage fairing from forward to aft ends at the contact between the seal and fuselage, and related investigative/ corrective actions if necessary. The original NPRM provided credit for accomplishment of certain service bulletins before the effective date of the AD. Since the original NPRM was issued, we have learned that two of the documents (BAE Systems (Operations) Limited Inspection Service Bulletins ISB.53–005, dated August 15, 1984, and ISB.53–067, dated December 23, 1987) are unavailable. We are therefore unable to determine the appropriateness of all of the procedures described in the service bulletin and must remove those references from this supplemental NPRM. Comments We have considered the following comments on the original NPRM. Request To Correct Typographical Errors The commenter, on behalf of Air Wisconsin Airlines Corporation, notes that the proposed AD misidentified two reference documents. In paragraph (c), the last Modification number should be HCM01698A. In paragraph (i), Table 1, the date listed for ISB.53–005, Revision 1, should be April 19, 1985. We have corrected these references in this supplemental NPRM. Additional Change to Original NPRM We have revised the statement of the unsafe condition to clarify the effect of chafing or scoring in the skin along the full length of the wing-to-fuselage fairing from the forward to aft ends at the contact between the seal and fuselage. FAA’s Determination and Proposed Requirements of the Supplemental NPRM Certain changes discussed above expand the scope of the original NPRM; therefore, we have determined that it is E:\FR\FM\05APP1.SGM 05APP1 17038 Federal Register / Vol. 71, No. 65 / Wednesday, April 5, 2006 / Proposed Rules necessary to reopen the comment period to provide additional opportunity for public comment on this supplemental NPRM. Costs of Compliance The following table provides the estimated costs for U.S. operators to comply with this supplemental NPRM.

Inspection (ISB.53–067) ................................................ cchase on PROD1PC60 with PROPOSALS 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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 the proposed regulation: 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.

Airworthiness Directives; BAE Systems (Operations) Limited Model 
BAe 146 Airplanes

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

ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of 
comment period.

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

SUMMARY: The FAA is revising an earlier NPRM for an airworthiness 
directive (AD) that applies to certain BAE Systems (Operations) Limited 
Model BAe 146 airplanes. The original NPRM would have required 
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. The original 
NPRM resulted from a report of chafing in this area. This action 
revises the original NPRM by removing certain credit for prior 
accomplishment of proposed requirements. We are proposing this 
supplemental NPRM to detect and correct such chafing or scoring, which 
could result in reduced structural integrity of the fuselage.

DATES: We must receive comments on this supplemental NPRM by May 1, 
2006.

Discussion

    We proposed to amend 14 CFR part 39 with a notice of proposed 
rulemaking (NPRM) for an airworthiness directive (AD) (the ``original 
NPRM''). The original NPRM applies to certain BAE Systems (Operations) 
Limited Model BAe 146 airplanes. The original NPRM was published in the 
Federal Register on November 15, 2005 (70 FR 69286). The original 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.
    The original NPRM provided credit for accomplishment of certain 
service bulletins before the effective date of the AD. Since the 
original NPRM was issued, we have learned that two of the documents 
(BAE Systems (Operations) Limited Inspection Service Bulletins ISB.53-
005, dated August 15, 1984, and ISB.53-067, dated December 23, 1987) 
are unavailable. We are therefore unable to determine the 
appropriateness of all of the procedures described in the service 
bulletin and must remove those references from this supplemental NPRM.

Comments

    We have considered the following comments on the original NPRM.

Request To Correct Typographical Errors

    The commenter, on behalf of Air Wisconsin Airlines Corporation, 
notes that the proposed AD misidentified two reference documents. In 
paragraph (c), the last Modification number should be HCM01698A. In 
paragraph (i), Table 1, the date listed for ISB.53-005, Revision 1, 
should be April 19, 1985.
    We have corrected these references in this supplemental NPRM.

Additional Change to Original NPRM

    We have revised the statement of the unsafe condition to clarify 
the effect of chafing or scoring in the skin along the full length of 
the wing-to-fuselage fairing from the forward to aft ends at the 
contact between the seal and fuselage.

FAA's Determination and Proposed Requirements of the Supplemental NPRM

    Certain changes discussed above expand the scope of the original 
NPRM; therefore, we have determined that it is

[[Page 17038]]

necessary to reopen the comment period to provide additional 
opportunity for public comment on this supplemental NPRM.

Costs of Compliance

    The following table provides the estimated costs for U.S. operators 
to comply with this supplemental NPRM.

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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 the proposed 
regulation:
    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 supplemental NPRM and placed it in the AD docket. See 
the ADDRESSES section for a location to examine the regulatory 
evaluation.

Sec.  39.13  [Amended]

    2. The Federal Aviation Administration (FAA) amends Sec.  39.13 by 
adding the following new airworthiness directive (AD):

BAE Systems (Operations) Limited (Formerly British Aerospace 
Regional Aircraft): Docket No. FAA-2005-22974; Directorate 
Identifier 2005-NM-180-AD.

Comments Due Date

    (a) The FAA must receive comments on this AD action by May 1, 
2006.

Affected ADs

    (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) Before the airplane accumulates 1,000 total flight cycles, 
or within 500 flight cycles after the effective date of this AD, 
whichever occurs later: 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. 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 related investigative/corrective actions and repeat the 
inspection to measure the chafing/scoring at the times specified in 
the service bulletins, as applicable.

Exceptions to Service Bulletin Specifications

    (g) Where the service bulletins referenced in this AD specify to 
contact the manufacturer for repair instructions: Before further 
flight, repair using a method approved by either the Manager, 
International Branch, ANM-116, Transport Airplane Directorate, FAA; 
or the Civil Aviation Authority (or its delegated agent).
    (h) Although the service bulletins referenced in this AD specify 
to submit certain information to the manufacturer, this AD does not 
include that requirement.

Credit for Earlier Accomplishment

    (i) Inspections and applicable investigative and corrective 
actions done before the effective date of this AD are acceptable for 
compliance with the requirements of paragraph (f) of this AD if done 
in accordance with one of the service bulletin versions identified 
in Table 1 of this AD, as applicable.
