Federal Register Abstract
The FAA is superseding an existing airworthiness directive (AD) that applies to certain Model 767-200, -300, and -300F series airplanes. The existing AD currently requires repetitive detailed and eddy current inspections to detect cracks or corrosion of certain midspar fuse pins, and corrective actions if necessary. That AD also provides optional terminating action, which ends the repetitive inspections. This new AD requires reduced intervals for certain repetitive inspections. This AD results from a report of a fractured midspar fuse pin. We are issuing this AD to prevent loss of the strut and engine due to corrosion damage and cracking of both fuse pins on the same strut.

SUPPLEMENTARY INFORMATION:
Discussion
On January 22, 2003, we issued AD 2003-03-02, amendment 39-13026
(68 FR 4374, January 29, 2003). That AD applies to certain Model 767-
200, -300, and -300F airplanes. That AD requires repetitive detailed
and eddy current inspections to detect cracks and corrosion of certain
midspar fuse pins, and corrective actions if necessary. That AD also
provides optional terminating action, which ends the repetitive
inspections. That AD resulted from a report of a fractured outboard
midspar fuse pin (part number (P/N) 311T3102-1) of the left engine
pylon, which was found during a scheduled maintenance visit. The fuse
pin also had corrosion on the pin and within the bore. The actions
specified in that AD are intended to prevent loss of the strut and
engine due to corrosion damage and cracking of both fuse pins on the
same strut.
Actions Since AD Was Issued
Since we issued that AD, we received a report that a fractured
midspar fuse pin was found on a Model 767-300 airplane with CF6-80C2
engines. The airplane had accumulated 16,054 flight cycles and neither
Boeing Service Bulletin 767-54-0069 (required by AD 2000-19-09,
amendment 39-11910; AD 2001-02-07, amendment 39-12091; and AD 2001-06-
12, amendment 39-12159) nor Boeing Service Bulletin 767-54-0081
(required by AD 2001-06-12) had been incorporated. (ADs 2001-02-07 and
2001-06-12 have been superseded by AD 2004-16-12, amendment 39-13768.)
The fractured midspar fuse pin was found during routine maintenance on
the outboard side of the number one pylon, prior to the next scheduled
midspar fuse pin inspection in accordance with Boeing Alert Service
Bulletin 767-54A0062, Revision 5, dated November 11, 2002 (referenced
in AD 2003-03-02). Further inspection revealed a cracked midspar fuse
pin on the inboard side of the number one pylon. Subsequent inspection
of both midspar fuse pins revealed discrepant circumferential machining
grooves on the fuse pin main bore surface, in addition to longitudinal
cracks. In addition, eddy current inspection of the midspar fuse pins
in accordance with the requirements of Revision 5 of this service
bulletin will not reveal the maximum allowable roughness of the fuse
pin main bore surface. Metallurgical analysis determined the fuse pin
fracture or crack origins coincided with the discrepant
[[Page 5678]]
machining groove locations, in all cases. Stresses due to pin
ovalization contributed to the longitudinal cracking of the midspar
fuse pins.
Relevant Service Information
We have reviewed Boeing Alert Service Bulletin 767-54A0062,
Revision 6, dated November 5, 2009. The service bulletin describes
procedures similar to those in Boeing Alert Service Bulletin 767-
54A0062, Revision 5, dated November 11, 2002 (referred to in AD 2003-
03-02 as a method of accomplishing the required actions), but with
reduced repetitive inspection intervals. Revision 6 of this service
bulletin does provide optional corrective actions for certain
conditions; a repair of the midspar fuse pin may be done instead of
replacing the pin. The repair includes contacting Boeing for repair
instructions and doing the repair. Revision 6 of this service bulletin
also revises the corrective actions for corrosion by basing the
condition on corrosion found on a non-critical surface or any surface
other than a non-critical surface.
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 2003-03-02. This new AD retains
certain requirements of the existing AD. This AD also reduces intervals
for repeat inspections and requires accomplishing the actions specified
in Boeing Alert Service Bulletin 767-54A0062, Revision 6, dated
November 5, 2009, described previously, except as discussed under
``Difference Between the AD and the Service Bulletin.''
Difference Between the AD and the Service Bulletin
Boeing Alert Service Bulletin 767-54A0062, Revision 6, dated
November 5, 2009, specifies to ``Contact Boeing for repair instructions
* * *.'' This AD would require repairing in accordance with a method
approved by the Manager, Seattle Aircraft Certification Office, FAA.
Change to Existing AD
This AD would retain certain requirements of AD 2003-03-02. Since
AD 2003-03-02 was issued, the AD format has been revised, and certain
paragraphs have been rearranged. As a result, the corresponding
paragraph identifiers have changed in this AD, as listed in the
following table:

------------------------------------------------------------------------
FAA's Justification and Determination of the Effective Date
A fractured midspar fuse pin was discovered after the issuance of
AD 2003-03-02. Fractured, corroded, or cracked midspar fuse pins could
lead to the separation of the strut and engine from the airplane.
Because of our requirement to promote safe flight of civil aircraft and
thus, the critical need to assure the structural integrity of the
engine strut 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-2010-0031; Directorate Identifier 2009-NM-266-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 <a href="http://www.regulations.gov">http://www.regulations.gov</a>, 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, 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.
