SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an airworthiness directive (AD) that would apply to the specified products. That NPRM published in the Federal Register on January 3, 2011 (76 FR 31). That NPRM proposed to require replacing the existing unshielded fuel quantity indication system (FQIS) wire bundles with double shielded FQIS wire bundles, installing a new wire feedthrough fitting, and grounding the wire shields, as applicable; and doing repetitive low frequency eddy current (LFEC) inspections for cracking of the fuselage skin, and corrective actions if necessary. That NPRM also proposed to require revising the maintenance program to incorporate certain airworthiness limitations. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comment received on the proposal and the FAA’s response to the comment. Request for Explanation of Alternative Method of Compliance (AMOC) Authority for Structures Portions of the NPRM Boeing requested that we explain that some designees with AMOC authority may be necessary for the structural PO 00000 Frm 00025 Fmt 4700 Sfmt 4700 33991 portions of the AD. Boeing stated that repairs to airplane structure, if needed, would also be an AMOC to the AD and would need to be noted as such and approved by the FAA or a Boeing Authorized Representative designated with AMOC authority for the structural aspects of this installation. Boeing added that any repair would need to address damage tolerance issues associated with 14 CFR 25.571 and 14 CFR part 26, subpart E. of the Federal Aviation Regulations. Boeing stated that these requirements are the basis for the inspections provided in Boeing Service Bulletin 727–28–0131, dated August 18, 2010, and changes to the installation with repairs may revise the inspection requirements. We agree with the request to add explanatory information to paragraph (i) of this AD. Any structural repairs that cannot be done in accordance with the accomplishment instructions of Boeing Service Bulletin 727–28–0131, dated August 18, 2010, will require a request for an AMOC. The requested AMOC, if it provides an acceptable level of safety, may be approved by the Boeing Commercial Airplanes Organization Designation Authorization (ODA) that has been authorized by the Manager, Seattle ACO to make those findings. Paragraph (i) of this AD has been changed to explain that some designees with AMOC authority for the structures portions of the AD might be necessary. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting the AD with the change described previously and minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. We also determined that these changes will not increase the economic burden on any operator or increase the scope of the AD. Costs of Compliance We estimate that this AD affects 566 airplanes of U.S. registry. We estimate the following costs to comply with this AD: E:\FR\FM\10JNR1.SGM 10JNR1 33992 Federal Register / Vol. 76, No. 112 / Friday, June 10, 2011 / Rules and Regulations ESTIMATED COSTS Action Labor cost Installation .............................................

We have received no definitive data that would enable us to provide a cost estimate for the on-condition action specified in 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. WReier-Aviles on DSKGBLS3C1PROD with RULES 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), (3) Will not affect intrastate aviation in Alaska, and (4) 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. 14:29 Jun 09, 2011 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

SUPPLEMENTARY INFORMATION: Recent political turmoil in Libya has affected Exchange Visitor Program college and university students studying in the United States. Many of the students dependent upon financial support originating in their home country have found themselves without funds. To ameliorate the hardship arising from this lack of financial support and facilitate these students’ continued studies, the Department is suspending the application of the full course of study requirement set forth at 22 CFR 62.23(e), the application of the requirements governing student employment set forth at 22 CFR 62.23(g), and the application of the duration of participation requirements set forth at 22 CFR 62.23(h) effective June 10, 2011 until December 31, 2011. The temporary suspension of certain requirements governing program status and on-campus and off-campus employment for J–1 Libyan students does not apply to Federal Work-Study jobs. College and university students in J– 1 status whose means of financial support come from Libya and whose financial support has been disrupted, reduced, or eliminated due to turmoil in their home country may be authorized by the Responsible Officer of their academic institution to pursue full-time or part-time on-campus or off-campus employment. A reduction in the students’ academic course load may also be necessary due to this employment and accordingly, such students will be deemed to be in valid J–1 Exchange Visitor Program student status if they are (i) an undergraduate student and enrolled for not less than six semester hours of academic credit or its recognized equivalent; (ii) a graduate student enrolled for not less than three hours of academic credit or its recognized equivalent; (iii) a non-degree student actively participating on not less than a half-time equivalent basis in the prescribed course of study for which the student was initially authorized J–1 student status; or (iv) a non-degree student actively pursuing English language instruction on not less than a half-time equivalent basis.

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above. This AD requires replacing the existing 
unshielded fuel quantity indication system (FQIS) wire bundles with 
double shielded FQIS wire bundles, installing a new wire feed-through 
fitting, and grounding the wire shields, as applicable; and doing 
repetitive low frequency eddy current (LFEC) inspections for cracking 
of the fuselage skin, and corrective actions if necessary. This AD also 
requires revising the maintenance program to incorporate certain 
airworthiness limitations. This AD was prompted by fuel system reviews 
conducted by the manufacturer. We are issuing this AD to increase the 
level of protection from lightning strikes and prevent the potential of 
ignition sources inside fuel tanks, which, in combination with 
flammable fuel vapors, could result in fuel tank explosions and 
consequent loss of the airplane.

DATES: This AD is effective July 15, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of July 15, 2011.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an airworthiness directive (AD) that would apply to 
the specified products. That NPRM published in the Federal Register on 
January 3, 2011 (76 FR 31). That NPRM proposed to require replacing the 
existing unshielded fuel quantity indication system (FQIS) wire bundles 
with double shielded FQIS wire bundles, installing a new wire feed-
through fitting, and grounding the wire shields, as applicable; and 
doing repetitive low frequency eddy current (LFEC) inspections for 
cracking of the fuselage skin, and corrective actions if necessary. 
That NPRM also proposed to require revising the maintenance program to 
incorporate certain airworthiness limitations.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comment received on the proposal 
and the FAA's response to the comment.

Request for Explanation of Alternative Method of Compliance (AMOC) 
Authority for Structures Portions of the NPRM

    Boeing requested that we explain that some designees with AMOC 
authority may be necessary for the structural portions of the AD. 
Boeing stated that repairs to airplane structure, if needed, would also 
be an AMOC to the AD and would need to be noted as such and approved by 
the FAA or a Boeing Authorized Representative designated with AMOC 
authority for the structural aspects of this installation. Boeing added 
that any repair would need to address damage tolerance issues 
associated with 14 CFR 25.571 and 14 CFR part 26, subpart E. of the 
Federal Aviation Regulations. Boeing stated that these requirements are 
the basis for the inspections provided in Boeing Service Bulletin 727-
28-0131, dated August 18, 2010, and changes to the installation with 
repairs may revise the inspection requirements.
    We agree with the request to add explanatory information to 
paragraph (i) of this AD. Any structural repairs that cannot be done in 
accordance with the accomplishment instructions of Boeing Service 
Bulletin 727-28-0131, dated August 18, 2010, will require a request for 
an AMOC. The requested AMOC, if it provides an acceptable level of 
safety, may be approved by the Boeing Commercial Airplanes Organization 
Designation Authorization (ODA) that has been authorized by the 
Manager, Seattle ACO to make those findings. Paragraph (i) of this AD 
has been changed to explain that some designees with AMOC authority for 
the structures portions of the AD might be necessary.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
the AD with the change described previously and minor editorial 
changes. We have determined that these minor changes:
     [Agr]re consistent with the intent that was proposed in 
the NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of the AD.

Costs of Compliance

    We estimate that this AD affects 566 airplanes of U.S. registry.
    We estimate the following costs 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

    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),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) 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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

Adoption of the Amendment

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

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2011-12-05 The Boeing Company: Amendment 39-16712; Docket No. FAA-
2010-1272; Directorate Identifier 2010-NM-226-AD.

Effective Date

    (a) This AD is effective July 15, 2011.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to The Boeing Company Model 727, 727C, 727-
100, 727-100C, 727-200, and 727-200F series airplanes, all variable 
numbers, certificated in any category.

    Note 1:  This AD requires revisions to certain operator 
maintenance documents to include new inspections. Compliance with 
these inspections is required by 14 CFR 91.403(c). For airplanes 
that have been previously modified, altered, or repaired in the 
areas addressed by these inspections, the operator may not be able 
to accomplish the inspections described in the revisions. In this 
situation, to comply with 14 CFR 91.403(c), the operator must 
request approval for an alternative method of compliance according 
to paragraph (l) of this AD. The request should include a 
description of changes to the required inspections that will ensure 
the continued operational safety of the airplane.

Subject

    (d) Joint Aircraft System Component (JASC)/Air Transport 
Association (ATA) of America Code 28, Fuel.

Unsafe Condition

    (e) This AD was prompted by fuel system reviews conducted by the 
manufacturer. We are issuing this AD to increase the level of 
protection from lightning strikes and prevent the potential of 
ignition sources inside fuel tanks, which, in combination with 
flammable fuel vapors, could result in fuel tank explosions and 
consequent loss of the airplane.

Compliance

    (f) Comply with this AD within the compliance times specified, 
unless already done.

Installation

    (g) Within 60 months after the effective date of this AD, 
install double shielded fuel quantity indicating system (FQIS) wire 
bundles, install a new wire feed-through fitting, and ground the 
wire shields, as applicable, in accordance with Part 1 of the 
Accomplishment Instructions of Boeing Service Bulletin 727-28-0131, 
dated August 18, 2010.

Repetitive Inspections

    (h) At the applicable times specified in paragraphs (h)(1) or 
(h)(2) of this AD, do low frequency eddy current (LFEC) inspections 
for cracking of the fuselage skin, in accordance with Part 2 of the 
Accomplishment Instructions of Boeing Service Bulletin 727-28-0131, 
dated August 18, 2010.
    (1) For Model 727, 727-100, 727-100C, and 727C series airplanes: 
Before the accumulation of 45,000 total flight cycles, or within 
8,000 flight cycles after the effective date of this AD, whichever 
occurs later. Repeat the inspections thereafter at intervals not to 
exceed 8,000 flight cycles.
    (2) For Model 727-200 and 727-200F series airplanes: Before the 
accumulation of 45,000 total flight cycles, or within 16,000 flight 
cycles after the effective date of this AD, whichever occurs later. 
Repeat the inspections thereafter at intervals not to exceed 16,000 
flight cycles.
    (i) If any cracking is found during any inspection required by 
paragraph (h) of this AD: Before further flight, repair the crack in 
accordance with a method approved by the Manager, Seattle ACO, FAA. 
For a repair method to be approved, the repair must meet

[[Page 33993]]

the certification basis of the airplane, and the approval must 
specifically refer to this AD. An alternative method of compliance 
that provides an acceptable level of safety may be used for any 
repair required by this AD if it is approved by the Boeing 
Commercial Airplanes Organization Designation Authorization (ODA) 
that has been authorized by the Manager, Seattle ACO, to make those 
findings.

Maintenance Program Revision

    (j) Before or concurrently with doing the actions required by 
paragraph (g) of this AD, or within 30 days after the effective date 
of this AD, whichever occurs later: Revise the maintenance program 
by incorporating airworthiness limitations (AWL) No. 28-AWL-18 and 
28-AWL-19 in Section D of Section 9 (``AIRWORTHINESS LIMITATIONS-
FUEL SYSTEMS'') of the Boeing 727-100/200 Airworthiness Limitations 
(AWLs) Document, D6-8766-AWL, Revision August 2010. The initial 
compliance time for AWL No. 28-AWL-18 is within 10 years after the 
accomplishment of paragraph (g) of this AD, or within 10 years after 
the effective date of this AD, whichever occurs later.

No Alternative Inspections, Inspection Intervals, or Critical Design 
Configuration Control Limitations (CDCCLs)

    (k) After accomplishing the action specified in paragraph (j) of 
this AD, no alternative inspections, inspection intervals, or CDCCLs 
may be used unless the inspections, intervals, or CDCCLs are 
approved as an alternative method of compliance in accordance with 
the procedures specified in paragraph (l) of this AD.

Alternative Methods of Compliance (AMOCs)

    (l)(1) The Manager, Seattle ACO, FAA, has the authority to 
approve AMOCs for this AD, if requested using the procedures found 
in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request 
to your principal inspector or local Flight Standards District 
Office, as appropriate. If sending information directly to the 
manager of the ACO, send it to the attention of the person 
identified in the Related Information section of this AD. 
Information may be e-mailed to: 9-ANM-Seattle-ACO-AMOC-Requests@faa.gov.
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the local flight standards district office/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 the 
Boeing Commercial Airplanes ODA that 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.
