SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for certain
Boeing Model 767–200, –300, and
–300F series airplanes. This AD requires
replacing the inboard fairing seal
common to the vapor barrier seal of
each strut assembly. This AD is
prompted by discovery during
production that a section of vapor
barrier seal was missing from the spar
web cavities of the upper aft struts of
both wings. We are issuing this AD to
prevent flammable fluids from leaking
onto parts of a hot exhaust system of a
shut-down engine of an airplane on the
ground, which could result in ignition
of the flammable fluids and an
uncontained fire. This could also lead to
an emergency evacuation of the airplane
and possible injury to passengers.

SUPPLEMENTARY INFORMATION: The FAA
proposed to amend 14 CFR Part 39 with
an AD for certain Boeing Model 767–
200, –300, and –300F series airplanes.
That action, published in the Federal
Register on November 3, 2004 (69 FR
63963), proposed to require replacing
the inboard fairing seal common to the
vapor barrier seal of each strut
assembly.
DATES:
Comments
We provided the public the
opportunity to participate in the
development of this AD. We have
considered the comments that have
been submitted on the proposed AD.
Agreement With Proposed AD
Two commenters, the manufacturer
and an operator, agree with the
proposed AD.
Request for Extended Compliance Time
One commenter, another operator,
requests that we change the compliance
deadline from 60 months to 84 months
after the effective date. The operator
states that this will allow the airlines to
accomplish the required maintenance
within their heavy maintenance visit
schedules, thereby minimizing aircraft
out-of-service time and the associated
extra expense.
VerDate jul<14>2003
15:51 Mar 18, 2005
Jkt 205001
We do not agree with the commenter’s
request to extend the compliance time.
In developing an appropriate
compliance time for this action, we
considered the safety implications, the
level of effort needed to incorporate the
change, and normal maintenance
schedules for the timely
accomplishment of the modification. In
consideration of these items, we have
determined that a 60-month interval
will ensure an acceptable level of safety
and allow the modifications to be done
with no airplane out-of-service time
during scheduled maintenance intervals
for most affected operators. We have not
changed the final rule.
Conclusion
We have carefully reviewed the
available data, including the comments
that have been submitted, and
determined that air safety and the
public interest require adopting the AD
as proposed, except for minor editorial
changes.
Clarification of Costs of Compliance
We have discovered that the numbers
shown in the proposed AD were
incorrect for the worldwide total of
affected airplanes and affected airplanes
of U.S. registry. We have changed the
Costs of Compliance section of this AD
to reflect the correct numbers of affected
airplanes.
Costs of Compliance
There are about 723 airplanes
worldwide of the affected design. This
AD will affect about 228 airplanes of
U.S. registry. The actions will take about
4 work hours per airplane, at an average
labor rate of $65 per work hour.
Required parts will cost about $185 per
airplane. Based on these figures, the
estimated cost of the AD for U.S.
operators is $101,460, or $445 per
airplane.
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
PO 00000
Frm 00027
Fmt 4700
Sfmt 4700
13369
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. See the ADDRESSES section for
a location to examine the regulatory
evaluation.

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. See the ADDRESSES section for a location to
examine the regulatory evaluation.

Adoption of the Amendment
0
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):
2005-06-10 Boeing: Amendment 39-14018. Docket No. FAA-2004-19493;
Directorate Identifier 2004-NM-69-AD.
Effective Date
(a) This AD becomes effective April 25, 2005.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Boeing Model 767-200, -300, and -300F
series airplanes;
[[Page 13370]]
certificated in any category; equipped with General Electric and
Pratt and Whitney engines; as identified in Boeing Service Bulletin
767-54-0107, Revision 1, dated December 18, 2003.
Unsafe Condition
(d) This AD was prompted by discovery during production that a
section of vapor barrier seal was missing from the spar web cavities
of the upper aft struts of both wings. We are issuing this AD to
prevent flammable fluids from leaking onto parts of a hot exhaust
system of a shut-down engine of an airplane on the ground, which
could result in ignition of the flammable fluids and an uncontained
fire. This could also lead to an emergency evacuation of the
airplane and possible injury to passengers.
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.
Installation of Seal
(f) Within 60 months after the effective date of this AD,
replace the inboard fairing seal common to the vapor barrier seal of
each strut assembly with a new inboard fairing seal in accordance
with the Accomplishment Instructions of Boeing Service Bulletin 767-
54-0107, Revision 1, dated December 18, 2003.
Seal Installations Accomplished Per Previous Issue of Service Bulletin
(g) Seal installations accomplished in accordance with the
Accomplishment Instructions of Boeing Service Bulletin 767-54-0107,
dated January 16, 2003, are considered acceptable for compliance
with the corresponding action specified in this AD.
Alternative Methods of Compliance (AMOCs)
(h) The Manager, Seattle Aircraft Certification Office, FAA, has
the authority to approve AMOCs for this AD, if requested using the
procedures found in 14 CFR 39.19.
Material Incorporated by Reference
(i) You must use Boeing Service Bulletin 767-54-0107, Revision
1, dated December 18, 2003, to perform the actions that are required
by this AD, unless the AD specifies otherwise. The Director of the
Federal Register approves the incorporation by reference of this
