Transportation (DOT).

ACTION: Final rule; request for comments.

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

SUMMARY: The FAA is superseding an existing airworthiness directive 
(AD) that applies to certain Model 767-200, -300, and -300F series 
airplanes. The

[[Page 42593]]

existing AD currently requires repetitive inspections to detect 
discrepancies of the 8 aft-most fastener holes in the horizontal tangs 
of the midspar fitting of the strut, and corrective actions if 
necessary. The existing AD also requires repetitive inspections for 
cracks of the closeout angle that covers the 2 aft-most fasteners in 
the lower tang of the midspar fitting, and related investigative and 
corrective actions if necessary. The existing AD also provides an 
optional terminating action for the repetitive inspections. This new AD 
reduces the compliance times for doing the inspections. This AD results 
from reports of cracks in the midspar fitting tangs. We are issuing 
this AD to detect and correct fatigue cracking in the primary strut 
structure and reduced structural integrity of the strut, which could 
result in separation of the strut and engine.

DATES: This AD becomes effective August 6, 2010.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of August 6, 
2010.
    We must receive any comments on this AD by September 7, 2010.

SUPPLEMENTARY INFORMATION:

Discussion

    On September 13, 2005, we issued AD 2005-19-23, amendment 39-14288 
(70 FR 55519, September 22, 2005). That AD applies to certain Boeing 
Model 767-200, -300, and -300F series airplanes. That AD 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 requires 
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 AD also 
provides an optional terminating action for the repetitive inspections. 
That AD resulted 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. The actions specified in that 
AD are intended 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.

Actions Since AD Was Issued

    Since we issued that AD, we received two reports of cracks in the 
midspar fitting tangs. The first report indicated severed upper and 
lower tangs at the aft two fastener locations in the Number 1 pylon 
inboard midspar fitting. The cracks were found during a routine check 
of a Model 767-300 airplane at approximately 92,205 total flight hours 
and 14,969 total flight cycles. This airplane had incurred 408 flight 
cycles from the previous inspection. The second report indicated cracks 
in the Number 1 pylon inboard midspar fitting lower tang, between the 
aft two fastener holes, on a Model 767-300 airplane at approximately 
94,176 total flight hours and 15,405 total flight cycles. This airplane 
had incurred 830 cycles from the previous inspection.
    AD 2005-19-23 specified repetitive inspection intervals between 
1,500 flight cycles and 16,000 flight cycles, depending on the 
inspection type and location. We have determined that the affected 
airplanes must be inspected within 400 flight cycles since the previous 
inspection and, for those airplanes that have not yet been inspected, 
the compliance time threshold of 10,000 total flight cycles specified 
in AD 2005-19-23 must be reduced to 8,000 total flight cycles. We have 
also determined that repetitive inspection intervals must be reduced to 
400 flight cycles and 6,000 flight cycles, depending on the inspection 
type.

Relevant Service Information

    We have reviewed Boeing Alert Service Bulletin 767-54A0101, 
Revision 5, dated June 29, 2010. We referred to Boeing Alert Service 
Bulletin 767-54A0101, Revision 4, dated February 10, 2005, for doing 
certain actions required by AD 2005-19-23. The procedures in Revision 5 
are similar to the procedures in Revision 4. Revision 5 reduces the 
compliance times for doing the procedures.
    We have also reviewed Boeing Alert Service Bulletin 767-54A0062, 
Revision 6, dated November 5, 2009; and Boeing Alert Service Bulletin 
767-54A0074, Revision 1, dated April 24, 2008; which are the latest 
versions of certain service bulletins referred to in AD 2005-19-23 as 
additional sources of guidance for doing the terminating action. Boeing 
Alert Service Bulletin 767-54A0101, Revision 5, dated June 29, 2010, 
refers to Boeing Alert Service Bulletin 767-54A0062, Revision 6, dated 
November 5, 2009; and Boeing Alert Service Bulletin 767-54A0074, 
Revision 1, dated April 24, 2008; as additional sources of guidance for 
doing the terminating action in Part 4 of the alert service bulletin.

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

FAA's Determination and Requirements of This AD

    The unsafe condition described previously is likely to exist or 
develop on other airplanes of the same type design. For this reason, we 
are issuing this AD to supersede AD 2005-19-23. This AD requires 
accomplishing the actions specified in Boeing Alert Service Bulletin 
767-54A0101, Revision 5, dated June 29, 2010, described previously, 
except as discussed under ``Differences Between the AD and the Service 
Bulletin.''

Differences Between the AD and the Service Bulletin

    The service bulletin specifies to contact the manufacturer for 
instructions on how to repair certain conditions, but this AD requires 
repairing those conditions in one of the following ways:
    <bullet> In accordance with a method that we approve; or
    <bullet> Using data that meet the certification basis of the 
airplane, and that have been approved by the Boeing Commercial 
Airplanes Organization Designation Authorization (ODA) whom we have 
authorized to make those findings.
    Steps 4.a. and 4.b. of Part 2 of the Work Instructions of Boeing 
Alert Service Bulletin 767-54A0101, Revision 5, dated June 29, 2010, 
specify actions if cracking is found and the hole size is either 
greater than 0.5322 inch or less than 0.5322 inch but not if the hole 
size equals 0.5322 inch. This AD specifies that if cracking is found 
and the hole size equals 0.5322 inch, then the terminating action 
specified in step 4.a. of Part 2 of the Work Instructions of Boeing 
Alert Service Bulletin 767-54A0101, Revision 5, dated June 29, 2010, 
must be accomplished.

Interim Action

    We consider this AD interim action. We are currently considering 
additional rulemaking to expand the inspection area.

FAA's Justification and Determination of the Effective Date

    Fatigue cracking in the primary strut structure could result in 
reduced structural integrity of the strut and consequent separation of 
the strut and engine. Because of our requirement to promote safe flight 
of civil aircraft and thus, the critical need to ensure the structural 
integrity of the pylon structure and midspar fittings and the short 
compliance time involved with this action, this AD must be issued 
immediately.
    Because an unsafe condition exists that requires the immediate 
adoption of this AD, we find that notice and opportunity for prior 
public comment hereon are impracticable and that good cause exists for 
making this amendment effective in less than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not provide you with notice and an opportunity to 
provide your comments before it becomes effective. However, we invite 
you to send any written data, views, or arguments about this AD. Send 
your comments to an address listed under the ADDRESSES section. Include 
``Docket No. FAA-2010-0671; Directorate Identifier 2010-NM-142-AD'' at 
the beginning of your comments. We specifically invite comments on the 
overall regulatory, economic, environmental, and energy aspects of this 
AD. We will consider all comments received by the closing date and may 
amend this AD because of those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about 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,

[[Page 42595]]

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 the 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 AD and placed it in the AD docket. See the ADDRESSES 
section for a location to examine the regulatory evaluation.
