Airworthiness Directives; Boeing
Model 747 Airplanes
SUMMARY: The FAA is superseding an
existing airworthiness directive (AD),
which applies to certain Boeing Model
747–200B, 747–200C, 747–200F, 747–
300, 747–400, and 747SP series
airplanes. That AD currently requires
doing a detailed inspection of the left
and right longeron extension fittings,
and corrective action if necessary. This
new AD adds airplanes to the
applicability of the existing AD. This
AD results from reports that accidental
drilling damage to the longeron
extension fittings was found on
airplanes not subject to the existing AD.
We are issuing this AD to detect and
correct accidental drilling damage of the
longeron extension fittings, which could
lead to cracking of the longeron
extension fittings and result in rapid
decompression of the airplane.
DATES: This AD becomes effective
February 11, 2008.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in the AD
as of February 11, 2008.
On June 16, 2006 (71 FR 27592, May
12, 2006), the Director of the Federal
Register approved the incorporation by
reference of Boeing Alert Service
Bulletin 747–53A2515, dated October
20, 2005.

SUPPLEMENTARY INFORMATION:
Discussion
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that
supersedes AD 2006–10–04, amendment
39–14588 (71 FR 27592, May 12, 2006).
The existing AD applies to certain
Boeing Model 747–200B, 747–200C,
747–200F, 747–300, 747–400, and
747SP series airplanes. That NPRM was
published in the Federal Register on
August 16, 2007 (72 FR 45973). That
NPRM proposed to continue to require
doing a detailed inspection of the left
and right longeron extension fittings,
and corrective action if necessary. That
NPRM also proposed to add airplanes to
the applicability of the existing AD.
Comments
We gave the public the opportunity to
participate in developing this AD. We
considered the single comment
received. Boeing supports the NPRM.
Clarification of Service Bulletins
Where paragraphs (h) and (i) of the
NPRM referred to ‘‘the alert service
bulletin’’ and ‘‘the service bulletin,’’ we
have specified the number, revision
level and date of those service bulletins
for clarity.
Conclusion
We reviewed the relevant data,
considered the comment received, and
determined that air safety and the
public interest require adopting the AD
with the changes described previously.
We also determined that these changes
will not increase the economic burden
on any operator or increase the scope of
the AD.
Interim Action
We consider this AD interim action. If
final action is later identified, we might
consider further rulemaking then.
Costs of Compliance
There are about 876 airplanes of the
affected design in the worldwide fleet.
This AD affects about 156 airplanes of
U.S. registry.
E:\FR\FM\07JAR1.SGM
07JAR1
Federal Register / Vol. 73, No. 4 / Monday, January 7, 2008 / Rules and Regulations
The actions specified by this AD were
previously required by AD 2006–10–04,
which was applicable to approximately
25 airplanes of U.S. registry. The actions
required by that AD take about 1 work
hour per airplane. We estimated the cost
of the current requirements of that AD
on U.S. operators to be $2,000, or $80
per airplane. Some operators of the 25
airplanes subject to AD 2006–10–04
may have already initiated the required
actions. This AD adds no new costs
associated with those airplanes.
This AD is applicable to
approximately 131 additional airplanes
of U.S. registry. New actions required by
this AD take about 1 work hour per
airplane. Based on the current labor rate
of $80 per work hour, we estimate the
new costs imposed by this AD on U.S.
operators to be $10,480, or $80 per
airplane. This figure is based on
assumptions that no operator of these
additional airplanes has yet done any of
the requirements of this AD, and that no
operator would do those actions in the
future if this AD were not adopted.
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.
sroberts on PROD1PC70 with RULES
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;
VerDate Aug<31>2005
18:28 Jan 04, 2008
Jkt 214001
(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.

SUMMARY: The FAA is superseding an
existing airworthiness directive (AD) for
Rolls-Royce Deutschland Ltd & Co KG
(RRD) Tay 611–8, Tay 620–15, Tay 650–
15, and Tay 651–54 turbofan engines.
That AD currently requires initial and
repetitive visual inspections of all iceimpact panels and fillers in the low
pressure (LP) compressor case for
certain conditions and replacing, as
necessary, any or all panels. This AD
requires the same actions, provides
terminating action to those repetitive
actions, and adds the Tay 611–8C
turbofan engine to the applicability.
This AD results from RRD introducing
new LP compressor case ice-impact
panels with additional retention
features to these Tay turbofan engines.
We are issuing this AD to prevent
release of ice-impact panels due to
improper bonding that can result in loss
of thrust in both engines.
DATES: This AD becomes effective
February 11, 2008. The Director of the
Federal Register previously approved
the incorporation by reference of certain
publications listed in the regulations as
of January 21, 2005 (70 FR 1172, January
6, 2005). The Director of the Federal
Register approved the incorporation by

proposed to amend 14 CFR part 39 by
superseding AD 2004–26–10,
Amendment 39–13922 (70 FR 1172,
January 6, 2005), with a proposed AD.
The proposed AD applies to RRD Tay
611–8, Tay 620–15, Tay 650–15, and
Tay 651–54 turbofan engines. We
published the proposed AD in the
Federal Register on July 6, 2007 (72 FR
36916). That action proposed to require
initial and repetitive visual inspections
of all ice-impact panels and fillers in the
LP compressor case for certain
conditions and replacing, as necessary,
any or all panels. That action also
proposed to provide terminating action
to those repetitive actions, and to add
the Tay 611–8C turbofan engine to the
applicability.

SUPPLEMENTARY INFORMATION:
Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to include an AD that supersedes AD 2006-10-04, amendment
39-14588 (71 FR 27592, May 12, 2006). The existing AD applies to
certain Boeing Model 747-200B, 747-200C, 747-200F, 747-300, 747-400,
and 747SP series airplanes. That NPRM was published in the Federal
Register on August 16, 2007 (72 FR 45973). That NPRM proposed to
continue to require doing a detailed inspection of the left and right
longeron extension fittings, and corrective action if necessary. That
NPRM also proposed to add airplanes to the applicability of the
existing AD.
Comments
We gave the public the opportunity to participate in developing
this AD. We considered the single comment received. Boeing supports the
NPRM.
Clarification of Service Bulletins
Where paragraphs (h) and (i) of the NPRM referred to ``the alert
service bulletin'' and ``the service bulletin,'' we have specified the
number, revision level and date of those service bulletins for clarity.
Conclusion
We reviewed the relevant data, considered the comment received, and
determined that air safety and the public interest require adopting the
AD with the changes described previously. We also determined that these
changes will not increase the economic burden on any operator or
increase the scope of the AD.
Interim Action
We consider this AD interim action. If final action is later
identified, we might consider further rulemaking then.
Costs of Compliance
There are about 876 airplanes of the affected design in the
worldwide fleet. This AD affects about 156 airplanes of U.S. registry.
[[Page 1047]]
The actions specified by this AD were previously required by AD
2006-10-04, which was applicable to approximately 25 airplanes of U.S.
registry. The actions required by that AD take about 1 work hour per
airplane. We estimated the cost of the current requirements of that AD
on U.S. operators to be $2,000, or $80 per airplane. Some operators of
the 25 airplanes subject to AD 2006-10-04 may have already initiated
the required actions. This AD adds no new costs associated with those
airplanes.
This AD is applicable to approximately 131 additional airplanes of
U.S. registry. New actions required by this AD take about 1 work hour
per airplane. Based on the current labor rate of $80 per work hour, we
estimate the new costs imposed by this AD on U.S. operators to be
$10,480, or $80 per airplane. This figure is based on assumptions that
no operator of these additional airplanes has yet done any of the
requirements of this AD, and that no operator would do those actions in
the future if this AD were not adopted.
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.

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 Federal Aviation Administration (FAA) amends Sec. 39.13 by
removing amendment 39-14588 (71 FR 27592, May 12, 2006) and by adding
the following new airworthiness directive (AD):
2007-26-17 Boeing: Amendment 39-15319. Docket No. FAA-2007-28989;
Directorate Identifier 2007-NM-070-AD.
Effective Date
(a) This AD becomes effective February 11, 2008.
Affected ADs
(b) This AD supersedes AD 2006-10-04.
Applicability
(c) This AD applies to Boeing Model 747-100, 747-100B, 747-100B
