ACTION: Final rule. AGENCY: SUMMARY: The FAA is superseding an existing airworthiness directive (AD), which applies to certain Boeing Model 767 series airplanes. That AD currently requires repetitive inspections to detect discrepancies of the eight aft-most fastener holes in the horizontal tangs of the midspar fitting of the strut, and corrective actions if necessary. That AD also provides an optional terminating action for the repetitive inspections. E:\FR\FM\22SER1.SGM 22SER1 55520 Federal Register / Vol. 70, No. 183 / Thursday, September 22, 2005 / Rules and Regulations This new AD adds repetitive inspections for cracks of the closeout angle that covers the two aft-most fasteners in the lower tang of the midspar fitting, and related investigative and corrective actions if necessary. This AD also reduces the inspection interval of the upper tang of the outboard midspar fitting; and provides an optional terminating action for the repetitive inspections. This AD results from a report of a crack in a closeout angle that covers the two aft-most fasteners in the lower tang of the midspar fitting; and the discovery of a crack in the lower tang of the midspar fitting under the cracked closeout angle. We are issuing this AD to prevent fatigue cracking in the primary strut structure and reduced structural integrity of the strut, which could result in separation of the strut and engine. EFFECTIVE DATE: This AD becomes effective October 27, 2005. The Director of the Federal Register approved the incorporation by reference of Boeing Alert Service Bulletin 767– 54A0101, Revision 4, dated February 10, 2005, listed in the AD as of October 27, 2005. On June 9, 2004 (69 FR 24947, May 5, 2004), the Director of the Federal Register approved the incorporation by reference of Boeing Service Bulletin 767–54A0101, Revision 3, dated September 5, 2002. On May 15, 2001 (66 FR 18523, April 10, 2001), the Director of the Federal Register approved the incorporation by reference of Boeing Service Bulletin 767–54A0101, Revision 1, dated February 3, 2000.

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 2004–09–14, amendment 39–13603 (69 FR 24947, May 5, 2004). The existing AD applies to certain Model 767 series airplanes. That NPRM was published in the Federal Register on June 3, 2005 (70 FR 32527). That NPRM proposed to continue to require repetitive inspections to detect discrepancies of the eight aft-most fastener holes in the horizontal tangs of the midspar fitting of the strut, and corrective actions if necessary. That NPRM also proposed to require repetitive inspections for cracks of the closeout angle that covers the two aftmost fasteners in the lower tang of the midspar fitting, and related investigative and corrective actions if necessary. That NPRM also proposed to reduce the inspection interval of the upper tang of the outboard midspar fitting; and to provide an optional terminating action for the repetitive inspections. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comments received. Request To Remove Airplane Reference From Applicability The airplane manufacturer requests that we remove the reference to Boeing Model 767–400ER series airplanes from the applicability of the NPRM. The commenter points out that these airplanes have improved corrosion resistant steel (CRES) mid-spar fittings. We agree with the commenter. The Model 767–400ER series airplanes are not included in the effectivity of the Boeing Alert Service Bulletin 767– 54A0101, Revision 4, dated February 10, 2005 (which was cited as the appropriate source of service information for doing the actions in the NPRM), but were inadvertently included in the applicability of the NPRM. We have changed the final rule to remove this model designation from the applicability. PO 00000 Frm 00008 Fmt 4700 Sfmt 4700 Request To Include Inspection Requirements for Airplanes With CRES Repair Strap The same commenter points out that some airplanes have had the closeout angle previously repaired by the addition of a CRES repair strap. This repair strap covers two aft-most bolts of the closeout angle at the midspar fitting. The commenter states that the repair strap prevents high-frequency eddy current inspections of the closeout angle. The commenter requests that the final rule include inspection requirements for these airplanes. We partially agree with the commenter. We agree that additional inspections may be required for these airplanes. We disagree with including inspection requirements for these airplanes in the final rule. In accordance with 14 CFR 39.17, if the original airplane configuration is altered, modified, or repaired in any way that may affect the ability to accomplish the actions of an AD, the operator should apply for an alternative method of compliance (AMOC) through the FAA. Information about AMOCs is included in paragraph (q) of the final rule. We have not changed the final rule in this regard. Explanation of Change Made to Paragraph (i) We have simplified paragraph (i) of the final rule by referring to the ‘‘Alternative Methods of Compliance (AMOCs)’’ paragraph of this AD for repair methods. Clarification of Alternative Method of Compliance (AMOC) Paragraph We have revised this action to clarify the appropriate procedure for notifying the principal inspector before using any approved AMOC on any airplane to which the AMOC applies. 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.

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. Jkt 205001 Number of U.S.-registered airplanes $65, per inspection cycle. $195, per inspection cycle. $260, per inspection cycle. $65 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. 15:53 Sep 21, 2005 Cost per airplane 1 Authority for This Rulemaking VerDate Aug<31>2005 Parts Fleet cost 263 N/A (depends on chosen option). 263 N/A (depends on chosen option). 263 $68,380, per inspection cycle.

Airworthiness Directives; Boeing Model 767-200, -300, and -300F
Series Airplanes Powered by General Electric or Pratt & Whitney Engines

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 Boeing Model 767 series airplanes. That
AD currently requires repetitive inspections to detect discrepancies of
the eight aft-most fastener holes in the horizontal tangs of the
midspar fitting of the strut, and corrective actions if necessary. That
AD also provides an optional terminating action for the repetitive
inspections.

[[Page 55520]]

This new AD adds repetitive inspections for cracks of the closeout
angle that covers the two aft-most fasteners in the lower tang of the
midspar fitting, and related investigative and corrective actions if
necessary. This AD also reduces the inspection interval of the upper
tang of the outboard midspar fitting; and provides an optional
terminating action for the repetitive inspections. This AD results from
a report of a crack in a closeout angle that covers the two aft-most
fasteners in the lower tang of the midspar fitting; and the discovery
of a crack in the lower tang of the midspar fitting under the cracked
closeout angle. We are issuing this AD to prevent fatigue cracking in
the primary strut structure and reduced structural integrity of the
strut, which could result in separation of the strut and engine.

EFFECTIVE DATE: This AD becomes effective October 27, 2005.
The Director of the Federal Register approved the incorporation by
reference of Boeing Alert Service Bulletin 767-54A0101, Revision 4,
dated February 10, 2005, listed in the AD as of October 27, 2005.
On June 9, 2004 (69 FR 24947, May 5, 2004), the Director of the
Federal Register approved the incorporation by reference of Boeing
Service Bulletin 767-54A0101, Revision 3, dated September 5, 2002.
On May 15, 2001 (66 FR 18523, April 10, 2001), the Director of the
Federal Register approved the incorporation by reference of Boeing
Service Bulletin 767-54A0101, Revision 1, dated February 3, 2000.

SUPPLEMENTARY INFORMATION:

Examining the Docket

You may examine the airworthiness directive (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 2004-09-14, amendment
39-13603 (69 FR 24947, May 5, 2004). The existing AD applies to certain
Model 767 series airplanes. That NPRM was published in the Federal
Register on June 3, 2005 (70 FR 32527). That NPRM proposed to continue
to require repetitive inspections to detect discrepancies of the eight
aft-most fastener holes in the horizontal tangs of the midspar fitting
of the strut, and corrective actions if necessary. That NPRM also
proposed to require repetitive inspections for cracks of the closeout
angle that covers the two aft-most fasteners in the lower tang of the
midspar fitting, and related investigative and corrective actions if
necessary. That NPRM also proposed to reduce the inspection interval of
the upper tang of the outboard midspar fitting; and to provide an
optional terminating action for the repetitive inspections.

Comments

We provided the public the opportunity to participate in the
development of this AD. We have considered the comments received.

Request To Remove Airplane Reference From Applicability

The airplane manufacturer requests that we remove the reference to
Boeing Model 767-400ER series airplanes from the applicability of the
NPRM. The commenter points out that these airplanes have improved
corrosion resistant steel (CRES) mid-spar fittings.
We agree with the commenter. The Model 767-400ER series airplanes
are not included in the effectivity of the Boeing Alert Service
Bulletin 767-54A0101, Revision 4, dated February 10, 2005 (which was
cited as the appropriate source of service information for doing the
actions in the NPRM), but were inadvertently included in the
applicability of the NPRM. We have changed the final rule to remove
this model designation from the applicability.

Request To Include Inspection Requirements for Airplanes With CRES
Repair Strap

The same commenter points out that some airplanes have had the
closeout angle previously repaired by the addition of a CRES repair
strap. This repair strap covers two aft-most bolts of the closeout
angle at the midspar fitting. The commenter states that the repair
strap prevents high-frequency eddy current inspections of the closeout
angle. The commenter requests that the final rule include inspection
requirements for these airplanes.
We partially agree with the commenter. We agree that additional
inspections may be required for these airplanes. We disagree with
including inspection requirements for these airplanes in the final
rule. In accordance with 14 CFR 39.17, if the original airplane
configuration is altered, modified, or repaired in any way that may
affect the ability to accomplish the actions of an AD, the operator
should apply for an alternative method of compliance (AMOC) through the
FAA. Information about AMOCs is included in paragraph (q) of the final
rule. We have not changed the final rule in this regard.

Explanation of Change Made to Paragraph (i)

We have simplified paragraph (i) of the final rule by referring to
the ``Alternative Methods of Compliance (AMOCs)'' paragraph of this AD
for repair methods.

Clarification of Alternative Method of Compliance (AMOC) Paragraph

We have revised this action to clarify the appropriate procedure
for notifying the principal inspector before using any approved AMOC on
any airplane to which the AMOC applies.

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.

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.
