Download as PDF 9880 Federal Register / Vol. 72, No. 43 / Tuesday, March 6, 2007 / Proposed Rules The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The Federal Aviation Administration (FAA) amends § 39.13 by adding the following new airworthiness directive (AD): Boeing: Docket No. FAA–2007–27359; Directorate Identifier 2006–NM–042–AD. Comments Due Date (a) The FAA must receive comments on this AD action by April 20, 2007. Affected ADs (b) AD 90–06–06, amendment 39–6490, paragraph A., requires installation of external skin doublers in the area near the flight deck windows for Group 1 airplanes, which ends the repetitive high-frequency eddy current (HFEC) inspections required by this AD only for those airplanes. Installing external skin doublers as required by paragraph (g) of this AD ends certain repetitive inspections of the fuselage skin required by paragraph (f) of AD 2005–08–01, amendment 39–14053, only for the area near the flight deck windows modified by the external skin doublers. Applicability (c) This AD applies to Boeing Model 747– 100, 747–100B, 747–200B, 747–200C, 747– 200F, 747–300, 747SR, and 747SP series airplanes, certificated in any category; as identified in Boeing Alert Service Bulletin 747–53A2542, dated February 16, 2006. Unsafe Condition (d) This AD results from reports of fatigue cracks in the fuselage skin near stringer 5 between body stations 340 and 350. We are issuing this AD to detect and correct fatigue cracking of the fuselage skin near stringer 5. Cracks in this area could join together and result in in-flight depressurization of the airplane. cprice-sewell on PROD1PC67 with PROPOSALS 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. Inspections and Corrective Actions (f) For any airplane that has not had external skin doublers installed around the left- or right-side Number 3 flight deck window in accordance with Boeing Service Bulletin 747–53–2272, Revision 18, dated May 16, 2002, or an earlier revision: Do the applicable actions described in paragraphs (f)(1) and (f)(2) of this AD. Do all the actions in and in accordance with the Accomplishment Instructions of Boeing Alert VerDate Aug<31>2005 15:32 Mar 05, 2007 Jkt 211001 Service Bulletin 747–53A2542, dated February 16, 2006. Do the actions at the compliance times specified in paragraph 1.E., ‘‘Compliance,’’ of Boeing Alert Service Bulletin 747–53A2542, dated February 16, 2006, on the side(s) of the airplane on which the doubler installation has not been done; except where the service bulletin specifies compliance times after the date on the service bulletin, this AD requires compliance times after the effective date of this AD. Installing external skin doublers around the left- or right-side Number 3 flight deck windows in accordance with Boeing Service Bulletin 747–53–2272, Revision 18, or an earlier revision; ends the repetitive HFEC inspections required by this paragraph on the side of the airplane on which the doubler is installed. After the effective date of this AD, only Boeing Service Bulletin 747–53–2272, Revision 18, may be used to install the external skin doublers around the left- and right-side Number 3 flight deck windows. (1) Do a HFEC inspection for cracks of the fuselage skin at stringer 5, between body stations 340 and 350; and do all applicable corrective actions before further flight. (2) Repeat the HFEC inspection thereafter at the applicable interval specified in paragraph 1.E. of Boeing Alert Service Bulletin 747–53A2542. Terminating Action (g) For Group 2 airplanes only: Before accumulating 24,000 total flight cycles, or within 250 flight cycles after the effective date of the AD, whichever occurs later, install external skin doublers around the leftand right-side Number 3 flight deck windows; in accordance with Boeing Service Bulletin 747–53–2272, Revision 17, dated November 18, 1999; or Revision 18, dated May 16, 2002. After the effective date of this AD, only Boeing Service Bulletin 747–53– 2272, Revision 18, may be used to accomplish the doubler installation around the left- and right-side Number 3 flight deck windows. Accomplishing this action ends the repetitive inspections required by paragraph (f) of this AD. Alternative Methods of Compliance (AMOCs) (h)(1) The Manager, Seattle Aircraft Certification Office (ACO), FAA, has the authority to approve AMOCs for this AD, if requested in accordance with the procedures found in 14 CFR 39.19. (2) Before using any AMOC approved in accordance with § 39.19 on any airplane to which the AMOC applies, notify the appropriate principal inspector in the FAA Flight Standards Certificate Holding District Office. (3) An AMOC that provides an acceptable level of safety may be used for any repair required by this AD, if it is approved by an Authorized Representative for the Boeing Commercial Airplanes Delegation Option Authorization Organization who has been authorized by the Manager, Seattle ACO, to make those findings. For a repair method to be approved, the repair must meet the certification basis of the airplane, and the approval must specifically refer to this AD.

ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of comment period. AGENCY: SUMMARY: The FAA is revising an earlier NPRM for an airworthiness directive (AD) that applies to certain Airbus Model A318, A319, A320, and A321 airplanes. The original NPRM would have superseded an existing AD that currently requires repetitive detailed inspections of the inboard flap trunnions for any wear marks and of the sliding panels for any cracking at the long edges, and corrective actions if necessary. The original NPRM proposed to add airplanes to the applicability in the existing AD and change the inspection type. The original NPRM resulted from a determination that certain airplanes must be included in the applicability of the AD, and that the inspection type must be revised. This new action revises the original NPRM by including airplanes that were inadvertently excluded from the applicability. We are proposing this supplemental NPRM to detect and correct wear of the inboard flap trunnions, which could lead to loss of flap surface control and consequently result in the flap detaching from the airplane. A detached flap could result in damage to the tail of the airplane. DATES: We must receive comments on this supplemental NPRM by April 2, 2007.

Comments will be available in the AD docket shortly after the Docket Management System receives them. Discussion The FAA issued a notice of proposed rulemaking (NPRM) (the ‘‘original NPRM’’) to amend 14 CFR part 39 to include an AD that supersedes AD 2006–04–06, amendment 39–14487 (71 FR 8439, February 17, 2006). The original NPRM applies to certain Airbus Model A318, A319, A320, and A321– 100 airplanes. The original NPRM was published in the Federal Register on August 22, 2006 (71 FR 48838). The original NPRM proposed to continue to require repetitive detailed inspections of the inboard flap trunnions for any wear marks and of the sliding panels for any cracking at the long edges, and corrective actions if necessary. The original NPRM also proposed to add airplanes to the applicability in the existing AD and change the inspection type. Actions Since Original NPRM Was Issued We have determined that the original NPRM should have applied to certain Airbus Model A318 airplanes, and all Airbus Model A319, A320, and A321– 111, –112, and –131 airplanes. In the original NPRM, we stated that we were adding Model A321–211 and –231 airplanes; however, the applicability was inadvertently changed to Model A318, A319, A320, and A321 airplanes on which Airbus Modification 26495 has been incorporated in production. The change resulted in the airplanes identified in paragraph (f) of the original NPRM (Model A319–111, –112, –113, –114, –115, –131, –132, and –133 airplanes; Model A320–111 airplanes; Model A320–211, –212, –214, –231, –232, and –233 airplanes; and Model A321–111, –112, and –131 airplanes; except those on which Airbus Modification 26495 has been accomplished in production) being excluded from the applicability of the original NPRM. We have changed the applicability in this supplemental NPRM to certain Airbus Model A318 airplanes, and ‘‘all’’ Airbus Model A319–111, –112, –113, –114, –115, –131, –132, and –133 airplanes; Model A320–111 airplanes; Model A320–211, –212, –214, –231, –232, and –233 airplanes; and Model A321–111, –112, –131, –211, and –231 airplanes. PO 00000 Frm 00010 Fmt 4702 Sfmt 4702 9881 Relevant Service Information Airbus has issued Service Bulletins A320–27–1117, Revision 03, dated August 24, 2001; and Revision 04, dated November 6, 2001. (Airbus Service Bulletin A320–27–1117, Revision 02, dated January 18, 2000, was referenced in the original NPRM as the appropriate source of service information for accomplishing the modification.) Airbus has also issued Airbus Service Bulletin A320–57–1133, Revision 01, dated August 7, 2006. (Airbus Service Bulletin A320–57–1133, dated July 28, 2005, was referenced in the original NPRM as the appropriate source of service information for accomplishing the inspections.) The changes in these revisions are minor and no additional work is necessary for airplanes modified by the previous issues. We have changed the AD to refer to this revised service information as the appropriate source of service information for accomplishing the required actions. In addition, we have added new paragraphs (k) and (l) to this AD to provide credit for accomplishing the actions before the effective date of this AD in accordance with the service information referenced in the original NPRM. Subsequent paragraphs have been re-identified accordingly. Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition. Comments We have considered the following comments on the original NPRM. Support for the NPRM Airbus supports the original NPRM. Request To Incorporate/Publish Certain Information The Modification and Replacement Parts Association (MARPA) states that, frequently, airworthiness directives are based on service information originating with the type certificate holder or its suppliers. MARPA adds that manufacturer service documents are privately authored instruments generally having copyright protection against duplication and distribution. MARPA notes that when a service document is incorporated by reference into a public document, such as an airworthiness directive, it loses its private, protected status and becomes a public document. MARPA adds that if a service document is used as a mandatory element of compliance, it should not simply be referenced, but should be incorporated into the regulatory document; by definition, public laws must be public, which E:\FR\FM\06MRP1.SGM 06MRP1 9882 Federal Register / Vol. 72, No. 43 / Tuesday, March 6, 2007 / Proposed Rules means they cannot rely upon private writings. MARPA notes that since the interpretation of a document is a question of law, and not fact, a service document not incorporated by reference will not be considered in a legal finding of the meaning of an airworthiness directive. MARPA is concerned that the failure to incorporate essential service information could result in a court decision invalidating the airworthiness directive. MARPA adds that incorporated by reference service documents should be made available to the public by publication in the Docket Management System (DMS), keyed to the action that incorporates them. MARPA notes that the stated purpose of the incorporation by reference method is brevity, to keep from expanding the Federal Register needlessly by publishing documents already in the hands of the affected individuals; traditionally, ‘‘affected individuals’’ means aircraft owners and operators, who are generally provided service information by the manufacturer. MARPA adds that a new class of affected individuals has emerged, since the majority of aircraft maintenance is now performed by specialty shops instead of aircraft owners and operators. MARPA notes that this new class includes maintenance and repair organizations, component servicing and repair shops, parts purveyors and distributors, and organizations manufacturing or servicing alternatively certified parts under section 21.303 (‘‘Replacement and modification parts’’) of the Federal Aviation Regulations (14 CFR 21.303). MARPA adds that the distribution to owners may, when the owner is a financing or leasing institution, not actually reach the persons responsible for accomplishing the airworthiness directive. Therefore, MARPA asks that the service documents deemed essential to the accomplishment of the NPRM be incorporated by reference into the regulatory instrument, and published in the DMS. We do not agree that documents should be incorporated by reference during the NPRM phase of rulemaking. The Office of the Federal Register (OFR) requires that documents that are necessary to accomplish the requirements of the AD be incorporated by reference during the final rule phase of rulemaking. We intend that the final rule in this action will incorporate by reference the documents necessary for the accomplishment of the proposed requirements mandated by this AD. Further, we point out that while documents that are incorporated by reference do become public information, they do not lose their copyright protection. For that reason, we advise the public to contact the manufacturer to obtain copies of the referenced service information. Additionally, we do not publish service documents in DMS. We are currently reviewing our practice of publishing proprietary service information. Once we have thoroughly examined all aspects of this issue, and have made a final determination, we will consider whether our current practice needs to be revised. However, we consider that to delay this AD action for that reason would be inappropriate, since we have determined that an unsafe condition exists and that the requirements in this AD must be accomplished to ensure continued safety. Therefore, we have not changed the supplemental NPRM in this regard. Clarification of Compliance Times and Applicability of Paragraphs (g) and (j)(2) of This Supplemental NPRM We have changed paragraphs (g) and (j)(2) of this supplemental NPRM (paragraph (i)(2) of the original NPRM) to specify the ‘‘applicable’’ compliance times in the subparagraphs. Paragraphs (g)(2) and (j)(2)(ii) of this supplemental NPRM are applicable only to airplanes that have not had Airbus Modification 26495 done in production. Revised Applicability in Paragraph (g) of This Supplemental NPRM We have changed the applicability in paragraph (g) of this supplemental NPRM for clarity and we have added Model A320–111 airplanes, which were inadvertently excluded from that paragraph in the original NPRM. Paragraph (g) is applicable to all airplanes identified in the existing AD, and Model A320–111 airplanes are included in that applicability. FAA’s Determination and Proposed Requirements of the Supplemental NPRM The changes discussed above expand the scope of the original NPRM; therefore, we have determined that it is necessary to reopen the comment period to provide additional opportunity for public comment on this supplemental NPRM.

Regulatory Findings Airbus: Docket No.: FAA–2006–25658; Directorate Identifier 2006–NM–054–AD. Comments Due Date (a) The FAA must receive comments on this AD action by April 2, 2007. Affected ADs (b) This AD supersedes AD 2006–04–06. 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. Applicability (c) This AD applies to the airplanes identified in paragraphs (c)(1) and (c)(2) of this AD, certificated in any category.

Airworthiness Directives; Airbus Model A318, A319, A320, and A321
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 Airbus Model A318, A319, A320,
and A321 airplanes. The original NPRM would have superseded an existing
AD that currently requires repetitive detailed inspections of the
inboard flap trunnions for any wear marks and of the sliding panels for
any cracking at the long edges, and corrective actions if necessary.
The original NPRM proposed to add airplanes to the applicability in the
existing AD and change the inspection type. The original NPRM resulted
from a determination that certain airplanes must be included in the
applicability of the AD, and that the inspection type must be revised.
This new action revises the original NPRM by including airplanes that
were inadvertently excluded from the applicability. We are proposing
this supplemental NPRM to detect and correct wear of the inboard flap
trunnions, which could lead to loss of flap surface control and
consequently result in the flap detaching from the airplane. A detached
flap could result in damage to the tail of the airplane.

DATES: We must receive comments on this supplemental NPRM by April 2,
2007.

Discussion

The FAA issued a notice of proposed rulemaking (NPRM) (the
``original NPRM'') to amend 14 CFR part 39 to include an AD that
supersedes AD 2006-04-06, amendment 39-14487 (71 FR 8439, February 17,
2006). The original NPRM applies to certain Airbus Model A318, A319,
A320, and A321-100 airplanes. The original NPRM was published in the
Federal Register on August 22, 2006 (71 FR 48838). The original NPRM
proposed to continue to require repetitive detailed inspections of the
inboard flap trunnions for any wear marks and of the sliding panels for
any cracking at the long edges, and corrective actions if necessary.
The original NPRM also proposed to add airplanes to the applicability
in the existing AD and change the inspection type.

Actions Since Original NPRM Was Issued

We have determined that the original NPRM should have applied to
certain Airbus Model A318 airplanes, and all Airbus Model A319, A320,
and A321-111, -112, and -131 airplanes. In the original NPRM, we stated
that we were adding Model A321-211 and -231 airplanes; however, the
applicability was inadvertently changed to Model A318, A319, A320, and
A321 airplanes on which Airbus Modification 26495 has been incorporated
in production. The change resulted in the airplanes identified in
paragraph (f) of the original NPRM (Model A319-111, -112, -113, -114, -
115, -131, -132, and -133 airplanes; Model A320-111 airplanes; Model
A320-211, -212, -214, -231, -232, and -233 airplanes; and Model A321-
111, -112, and -131 airplanes; except those on which Airbus
Modification 26495 has been accomplished in production) being excluded
from the applicability of the original NPRM. We have changed the
applicability in this supplemental NPRM to certain Airbus Model A318
airplanes, and ``all'' Airbus Model A319-111, -112, -113, -114, -115, -
131, -132, and -133 airplanes; Model A320-111 airplanes; Model A320-
211, -212, -214, -231, -232, and -233 airplanes; and Model A321-111, -
112, -131, -211, and -231 airplanes.

Relevant Service Information

Airbus has issued Service Bulletins A320-27-1117, Revision 03,
dated August 24, 2001; and Revision 04, dated November 6, 2001. (Airbus
Service Bulletin A320-27-1117, Revision 02, dated January 18, 2000, was
referenced in the original NPRM as the appropriate source of service
information for accomplishing the modification.) Airbus has also issued
Airbus Service Bulletin A320-57-1133, Revision 01, dated August 7,
2006. (Airbus Service Bulletin A320-57-1133, dated July 28, 2005, was
referenced in the original NPRM as the appropriate source of service
information for accomplishing the inspections.) The changes in these
revisions are minor and no additional work is necessary for airplanes
modified by the previous issues. We have changed the AD to refer to
this revised service information as the appropriate source of service
information for accomplishing the required actions. In addition, we
have added new paragraphs (k) and (l) to this AD to provide credit for
accomplishing the actions before the effective date of this AD in
accordance with the service information referenced in the original
NPRM. Subsequent paragraphs have been re-identified accordingly.
Accomplishing the actions specified in the service information is
intended to adequately address the unsafe condition.

Comments

We have considered the following comments on the original NPRM.

Support for the NPRM

Airbus supports the original NPRM.

Request To Incorporate/Publish Certain Information

The Modification and Replacement Parts Association (MARPA) states
that, frequently, airworthiness directives are based on service
information originating with the type certificate holder or its
suppliers. MARPA adds that manufacturer service documents are privately
authored instruments generally having copyright protection against
duplication and distribution. MARPA notes that when a service document
is incorporated by reference into a public document, such as an
airworthiness directive, it loses its private, protected status and
becomes a public document. MARPA adds that if a service document is
used as a mandatory element of compliance, it should not simply be
referenced, but should be incorporated into the regulatory document; by
definition, public laws must be public, which

[[Page 9882]]

means they cannot rely upon private writings. MARPA notes that since
the interpretation of a document is a question of law, and not fact, a
service document not incorporated by reference will not be considered
in a legal finding of the meaning of an airworthiness directive. MARPA
is concerned that the failure to incorporate essential service
information could result in a court decision invalidating the
airworthiness directive.
MARPA adds that incorporated by reference service documents should
be made available to the public by publication in the Docket Management
System (DMS), keyed to the action that incorporates them. MARPA notes
that the stated purpose of the incorporation by reference method is
brevity, to keep from expanding the Federal Register needlessly by
publishing documents already in the hands of the affected individuals;
traditionally, ``affected individuals'' means aircraft owners and
operators, who are generally provided service information by the
manufacturer. MARPA adds that a new class of affected individuals has
emerged, since the majority of aircraft maintenance is now performed by
specialty shops instead of aircraft owners and operators. MARPA notes
that this new class includes maintenance and repair organizations,
component servicing and repair shops, parts purveyors and distributors,
and organizations manufacturing or servicing alternatively certified
parts under section 21.303 (``Replacement and modification parts'') of
the Federal Aviation Regulations (14 CFR 21.303). MARPA adds that the
distribution to owners may, when the owner is a financing or leasing
institution, not actually reach the persons responsible for
accomplishing the airworthiness directive. Therefore, MARPA asks that
the service documents deemed essential to the accomplishment of the
NPRM be incorporated by reference into the regulatory instrument, and
published in the DMS.
We do not agree that documents should be incorporated by reference
during the NPRM phase of rulemaking. The Office of the Federal Register
(OFR) requires that documents that are necessary to accomplish the
requirements of the AD be incorporated by reference during the final
rule phase of rulemaking. We intend that the final rule in this action
will incorporate by reference the documents necessary for the
accomplishment of the proposed requirements mandated by this AD.
Further, we point out that while documents that are incorporated by
reference do become public information, they do not lose their
copyright protection. For that reason, we advise the public to contact
the manufacturer to obtain copies of the referenced service
information.
Additionally, we do not publish service documents in DMS. We are
currently reviewing our practice of publishing proprietary service
information. Once we have thoroughly examined all aspects of this
issue, and have made a final determination, we will consider whether
our current practice needs to be revised. However, we consider that to
delay this AD action for that reason would be inappropriate, since we
have determined that an unsafe condition exists and that the
requirements in this AD must be accomplished to ensure continued
safety. Therefore, we have not changed the supplemental NPRM in this
regard.

Clarification of Compliance Times and Applicability of Paragraphs (g)
and (j)(2) of This Supplemental NPRM

We have changed paragraphs (g) and (j)(2) of this supplemental NPRM
(paragraph (i)(2) of the original NPRM) to specify the ``applicable''
compliance times in the subparagraphs. Paragraphs (g)(2) and (j)(2)(ii)
of this supplemental NPRM are applicable only to airplanes that have
not had Airbus Modification 26495 done in production.

Revised Applicability in Paragraph (g) of This Supplemental NPRM

We have changed the applicability in paragraph (g) of this
supplemental NPRM for clarity and we have added Model A320-111
airplanes, which were inadvertently excluded from that paragraph in the
original NPRM. Paragraph (g) is applicable to all airplanes identified
in the existing AD, and Model A320-111 airplanes are included in that
applicability.

FAA's Determination and Proposed Requirements of the Supplemental NPRM

The changes discussed above expand the scope of the original NPRM;
therefore, we have determined that it is necessary to reopen the
comment period to provide additional opportunity for public comment on
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

[[Page 9883]]

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.

List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Safety.

The Proposed Amendment

Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

ensure visual access to all surfaces in the inspection area. This
level of inspection is made under normally available lighting
conditions such as daylight, hangar lighting, flashlight, or
droplight and may require removal or opening of access panels or
doors. Stands, ladders, or platforms may be required to gain
proximity to the area being checked.''
