ACTION: Notice of proposed rulemaking

AGENCY:
We propose to adopt a new
airworthiness directive (AD) for certain
Boeing Model 747–100, 747–100B, 747–
100B SUD, 747–200B, 747–200C, 747–
200F, 747–300, 747SR, and 747SP series
airplanes. This proposed AD would
require performing repetitive
operational tests of the engine fuel
suction feed of the fuel system, and
other related testing if necessary. This
proposed AD results from a report of inservice occurrences of loss of fuel
system suction feed capability, followed
by total loss of pressure of the fuel feed
system. We are proposing this AD to
detect and correct failure of the engine
fuel suction feed of the fuel system,
which could result in multi-engine
flameout, inability to restart the engines,
and consequent forced landing of the
airplane.
DATES: We must receive comments on
this proposed AD by July 21, 2008.

SUPPLEMENTARY INFORMATION:
Comments Invited
We invite you to send any written
relevant data, views, or arguments about
this proposed AD. Send your comments
to an address listed under the
ADDRESSES section. Include ‘‘Docket No.
FAA–2008–0619; Directorate Identifier
2007–NM–356–AD’’ at the beginning of
your comments. We specifically invite
comments on the overall regulatory,
economic, environmental, and energy
aspects of this proposed AD. We will
consider all comments received by the
closing date and may amend this
proposed AD because of those
comments.
We will post all comments we
receive, without change, to https://
www.regulations.gov, including any
personal information you provide. We
will also post a report summarizing each
substantive verbal contact we receive
about this proposed AD.
Discussion
We have received a report of inservice occurrences of loss of fuel
system suction feed capability, followed
by total loss of pressure of the fuel feed
system. This condition, if not corrected,
could result in multi-engine flameout,
inability to restart the engines, and
PO 00000
Frm 00003
Fmt 4702

32245
consequent forced landing of the
airplane.
FAA’s Conclusions
We have determined that it is
necessary to require an operational test
of the engine fuel suction feed of the
fuel system, and other related testing, as
applicable. Procedures for doing the
operational test can be found in the
maintenance manual. The other related
testing is for airplanes on which
deterioration in the engine RPM is
found on one or both of the engines
during the operational test. Failure of
the engine fuel suction feed of the fuel
system could result in the unsafe
condition described previously.
FAA’s Determination and Requirements
of This Proposed AD
We are proposing this AD because we
have evaluated all pertinent information
and identified an unsafe condition that
is likely to exist or develop on other
airplanes of this same type design. The
proposed AD would require performing
repetitive operational tests of the engine
fuel suction feed of the fuel system, and
other related testing if necessary.
Costs of Compliance
We estimate that this proposed AD
would affect 166 airplanes of U.S.
registry. We also estimate that it would
take 1 work-hour per product, per test,
to comply with this proposed AD. The
average labor rate is $80 per work-hour.
Based on these figures, we estimate the
cost of this proposed AD to the U.S.
operators to be $13,280, or $80 per
product, per test.
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.

Federal Register / Vol. 73, No. 110 / Friday, June 6, 2008 / Proposed Rules
Regulatory Findings
We determined that this proposed AD
would not have federalism implications
under Executive Order 13132. This
proposed AD would 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 this proposed 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.
You can find our regulatory
evaluation and the estimated costs of
compliance in the AD Docket.

The Proposed Amendment
Accordingly, under the authority
delegated to me by the Administrator,
the FAA proposes to amend 14 CFR part
39 as follows:
PART 39—AIRWORTHINESS
DIRECTIVES
1. The authority citation for part 39
continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
§ 39.13
[Amended]
2. The FAA amends § 39.13 by adding
the following new AD:

flameout, inability to restart the engines, and
consequent forced landing of the airplane.
Compliance
(e) Comply with this AD within the
compliance times specified, unless already
done.
Operational Test/Other Related Testing
(f) Within 30,000 flight hours after the
effective date of this AD, perform an
operational test of the engine fuel suction
feed of the fuel system, and perform all other
related testing, as applicable, before further
flight, according to a method approved by the
Manager, Seattle Aircraft Certification Office
(ACO), FAA. One approved method is the
operational test in Section 28–22–00, titled
‘‘Engine Fuel Feed System—Description and
Operation,’’ of the Boeing 747 Maintenance
Manual; and Boeing 747 Task Card 4–28–
007–05, titled ‘‘Engine Fuel Suction Feed
System,’’ dated April 25, 2007. Repeat the
operational test thereafter at intervals not to
exceed 30,000 flight hours. Thereafter, except
as provided in paragraph (g) of this AD, no
alternative procedure or repeat test intervals
will be allowed.
Alternative Methods of Compliance
(AMOCs)
(g)(1) The Manager, Seattle ACO, FAA,
ATTN: Sue Lucier, Aerospace Engineer,

917–6590, has the authority to approve
AMOCs for this AD, if requested using the
procedures found in 14 CFR 39.19.
(2) To request a different method of
compliance or a different compliance time
for this AD, follow the procedures in 14 CFR
39.19. Before using any approved AMOC on
any airplane to which the AMOC applies,
notify your appropriate principal inspector
(PI) in the FAA Flight Standards District
Office (FSDO), or lacking a PI, your local
FSDO.

ACTION:
SUMMARY: We propose to adopt a new
airworthiness directive (AD) for all
Boeing Model 747 airplanes. This
proposed AD would require inspecting
for cracks in the left- and right-side
Stringer 11 longeron adjacent to the
horizontal stabilizer pivot bulkhead,
and related investigative and corrective
actions if necessary. This proposed AD
results from a report of a crack found in
the right-side Stringer 11 longeron
horizontal flange, adjacent to the
horizontal stabilizer pivot bulkhead,
during a routine maintenance
inspection. We are proposing this AD to
detect and correct fatigue cracking of the
longeron, which can propagate and
cause damage to the adjacent horizontal
stabilizer pivot bulkhead. This damage
could result in loss of structural
integrity and consequent inability of the
bulkhead to carry flight loads, which
could adversely affect controllability of
the airplane.
DATES: We must receive comments on
this proposed AD by July 21, 2008.
