ACTION: Final rule.
AGENCY:
SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for certain
Boeing airplanes listed above. This AD
requires repetitive detailed inspections
of the midspar web of the inboard and/
or outboard struts for cracking,
disbonding, or buckling; repetitive
detailed inspections of the midspar
stiffeners for any crack or fracture;
related investigative actions; and
corrective actions, if necessary. This AD
is prompted by reports of cracking in
the midspar web. We are issuing this
AD to detect and correct cracking in the
midspar assembly, which could result
in the loss of the midspar assembly load
path, and could, combined with the loss
of the nacelle station 180 bulkhead load
path, lead to the separation of the
engine from the airplane.
DATES: This AD becomes effective
February 9, 2005.
The incorporation by reference of a
certain publication listed in the AD is
approved by the Director of the Federal
Register as of February 9, 2005.

AD, comments, and any final
disposition. You can examine the AD

SUPPLEMENTARY INFORMATION: The FAA
proposed to amend 14 CFR Part 39 with
an AD for certain Boeing Model 747–
100, –100B, –100B SUD, –200B, –200C,
–200F, and –300 series airplanes; and
Model 747SP and 747SR series
airplanes; equipped with Pratt &
Whitney JT9D–3 and –7 (except –70)
series engines or General Electric CF6–
50 series engines with modified JT9D–
7 inboard struts. That action, published
in the Federal Register on September
29, 2004 (69 FR 58101), proposed to
require repetitive detailed inspections of
the midspar web of the inboard and/or
outboard struts for cracking, disbonding,
or buckling; repetitive detailed
inspections of the midspar stiffeners for
any crack or fracture; related
investigative actions; and corrective
actions, if necessary.
Comments
We provided the public the
opportunity to participate in the
development of this AD. We have
considered the comment that has been
submitted on the proposed AD. The
commenter, the manufacturer, supports
the proposed AD.

Conclusion
We have carefully reviewed the
available data, including the comment
that has been submitted, and
determined that air safety and the
public interest require adopting the AD
as proposed.
Costs of Compliance
There are about 228 airplanes of the
affected design worldwide and 78
airplanes of U.S. registry. The actions
will take about 6 to 13 work hours per
airplane, at an average labor rate of $65
per work hour. Based on these figures,
the estimated cost of the AD for U.S.
operators is between $30,420 and
$65,910, or between $390 and $845 per
airplane, per inspection cycle.
Authority for This Rulemaking
The FAA’s authority to issue rules
regarding aviation safety is found in
Title 49 of the United States Code.
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.
This rulemaking is promulgated
under the authority described in
Subtitle VII, Part A, Subpart III, Section
44701, ‘‘General requirements.’’ Under
that section, the FAA is charged with
promoting safety 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
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 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. See the

ACTION: Final rule.
AGENCY:
SUMMARY: The FAA is superseding an
existing airworthiness directive (AD) for
certain Rolls-Royce plc (RR) RB211–524
series turbofan engines. That AD
currently requires initial and repetitive
borescope insepctions of the head
section and meterpanel assembly of the
combustion liner, and replacement, if
necessary, with serviceable parts. In
addition, that AD allows an optional
installation of a front combustion liner
with a strengthened head section as a
terminating action to the inspection
requirements. This AD requires initial
and repetitive borescope inspections of
the head section and meterpanel
assembly of the combustion liner, and
replacement if necessary with
serviceable parts. This AD also requires
reduction of the inspection intervals of
certain RB211–524 engine models that
have not been repaired to RR Field
Repair Scheme FRS5367/B, and a
mandatory terminating action to be
completed by a certain date. This AD
results from five events that are directly
attributed to combustor head breakup
and meterpanel failure which were
found at overhaul inspection. At least
one of these events resulted in a
combustion case burn-through. We are
issuing this AD to prevent engine
combustion liner deterioration, which
