ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
SUMMARY: The FAA proposes to adopt a
new airworthiness directive (AD) for
certain Boeing Model 747–400 series
airplanes. This proposed AD would
require inspecting the support bracket of
the crew oxygen cylinder installation to
determine the manufacturing date
marked on the support, and performing
corrective action if necessary. This
proposed AD results from a report
indicating that certain oxygen cylinder
supports may not have been properly
heat-treated. We are proposing this AD
to prevent failure of the oxygen cylinder
support under the most critical flight
load conditions, which could cause the
oxygen cylinder to come loose and leak
oxygen. Leakage of oxygen could result
in oxygen being unavailable for the
flightcrew or could result in a fire
hazard in the vicinity of the leakage.
DATES: We must receive comments on
this proposed AD by January 23, 2006.

Discussion
We have received a report indicating
that certain supports for the crew
oxygen cylinder on Boeing Model 747–
400 series airplanes may not have been
properly heat-treated during production.
These improperly heat-treated supports
could fail under the most critical flight
load conditions, which could cause the
oxygen cylinder to come loose and leak
oxygen. Leakage of oxygen could result
in oxygen being unavailable for the
flightcrew or could result in a fire
hazard in the vicinity of the leakage.
Relevant Service Information
We have reviewed Boeing Special
Attention Service Bulletin 747–35–
2114, dated December 19, 2002. The
service bulletin describes procedures for
inspecting the support bracket of the
crew oxygen cylinder installation to
determine the manufacturing date
marked on the support, and performing
corrective action if necessary. The
corrective action is replacing, with a
new support, any support with a
manufacturing date that is within a
certain range. Accomplishing the
actions specified in the service
information is intended to adequately
address the unsafe condition.
FAA’s Determination and Requirements
of the Proposed AD
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. For this reason, we are
proposing this AD, which would require
accomplishing the actions specified in
the service information described
previously, except as discussed under
‘‘Differences Between the Proposed AD
and Service Bulletin.’’
Differences Between the Proposed AD
and Service Bulletin
The service bulletin specifies a
compliance time of 90 days (for
airplanes with two crew oxygen
cylinders) or 18 months (for airplanes
with one crew oxygen cylinder).
However, this proposed AD would
require all airplanes to be in compliance
within 18 months after the effective date
of the AD. In developing an appropriate
compliance time for this AD, we
considered the manufacturer’s
recommendation, and the degree of
urgency associated with the subject
unsafe condition. In light of these
PO 00000
Frm 00006
Fmt 4702
Sfmt 4702
factors, we find that an 18-month
compliance time represents an
appropriate interval of time for affected
airplanes to continue to operate without
compromising safety. This difference
has been coordinated with Boeing.
Also, paragraph 1.E., Compliance, of
the service bulletin specifies that if the
configuration of the crew oxygen
cylinder installation is changed from a
one-cylinder configuration to a twocylinder configuration, the actions
specified in the service bulletin must be
done ‘‘immediately.’’ If the
configuration of the crew oxygen
cylinder support installation is changed
in this way, this proposed AD would
require you to do the actions in the
service bulletin before further flight
after the configuration change, or within
18 months after the effective date of the
AD, whichever is later.
Costs of Compliance
There are about 70 airplanes of the
affected design in the worldwide fleet.
This proposed AD would affect about 15
airplanes of U.S. registry. The proposed
inspection would take about 1 work
hour per airplane, at an average labor
rate of $65 per work hour. Based on
these figures, the estimated cost of the
proposed AD for U.S. operators is $975,
or $65 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
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
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
E:\FR\FM\09DEP1.SGM
09DEP1
Federal Register / Vol. 70, No. 236 / Friday, December 9, 2005 / Proposed Rules
responsibilities among the various
levels of government.
For the reasons discussed above, I
certify that the 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.
We prepared a regulatory evaluation
of the estimated costs to comply with
this proposed AD and placed it in the
AD docket. See the ADDRESSES section
for a location to examine the regulatory
evaluation.
List of Subjects in 14 CFR Part 39

Discussion
We have received a report indicating that certain supports for the
crew oxygen cylinder on Boeing Model 747-400 series airplanes may not
have been properly heat-treated during production. These improperly
heat-treated supports could fail under the most critical flight load
conditions, which could cause the oxygen cylinder to come loose and
leak oxygen. Leakage of oxygen could result in oxygen being unavailable
for the flightcrew or could result in a fire hazard in the vicinity of
the leakage.
Relevant Service Information
We have reviewed Boeing Special Attention Service Bulletin 747-35-
2114, dated December 19, 2002. The service bulletin describes
procedures for inspecting the support bracket of the crew oxygen
cylinder installation to determine the manufacturing date marked on the
support, and performing corrective action if necessary. The corrective
action is replacing, with a new support, any support with a
manufacturing date that is within a certain range. Accomplishing the
actions specified in the service information is intended to adequately
address the unsafe condition.
FAA's Determination and Requirements of the Proposed AD
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. For this reason, we are proposing this AD,
which would require accomplishing the actions specified in the service
information described previously, except as discussed under
``Differences Between the Proposed AD and Service Bulletin.''
Differences Between the Proposed AD and Service Bulletin
The service bulletin specifies a compliance time of 90 days (for
airplanes with two crew oxygen cylinders) or 18 months (for airplanes
with one crew oxygen cylinder). However, this proposed AD would require
all airplanes to be in compliance within 18 months after the effective
date of the AD. In developing an appropriate compliance time for this
AD, we considered the manufacturer's recommendation, and the degree of
urgency associated with the subject unsafe condition. In light of these
factors, we find that an 18-month compliance time represents an
appropriate interval of time for affected airplanes to continue to
operate without compromising safety. This difference has been
coordinated with Boeing.
Also, paragraph 1.E., Compliance, of the service bulletin specifies
that if the configuration of the crew oxygen cylinder installation is
changed from a one-cylinder configuration to a two-cylinder
configuration, the actions specified in the service bulletin must be
done ``immediately.'' If the configuration of the crew oxygen cylinder
support installation is changed in this way, this proposed AD would
require you to do the actions in the service bulletin before further
flight after the configuration change, or within 18 months after the
effective date of the AD, whichever is later.
Costs of Compliance
There are about 70 airplanes of the affected design in the
worldwide fleet. This proposed AD would affect about 15 airplanes of
U.S. registry. The proposed inspection would take about 1 work hour per
airplane, at an average labor rate of $65 per work hour. Based on these
figures, the estimated cost of the proposed AD for U.S. operators is
$975, or $65 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 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 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
[[Page 73173]]
responsibilities among the various levels of government.
For the reasons discussed above, I certify that the 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.
We prepared a regulatory evaluation of the estimated costs to
comply with this proposed AD and placed it in the AD docket. See the
ADDRESSES section for a location to examine the regulatory evaluation.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Safety.
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.
Sec. 39.13 [Amended]
2. The Federal Aviation Administration (FAA) amends Sec. 39.13 by
adding the following new airworthiness directive (AD):
Boeing: Docket No. FAA-2005-23250; Directorate Identifier 2005-NM-
150-AD.
Comments Due Date
(a) The FAA must receive comments on this AD action by January
23, 2006.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Boeing Model 747-400 series airplanes,
certificated in any category, as identified in Boeing Special
Attention Service Bulletin 747-35-2114, dated December 19, 2002.
Unsafe Condition
(d) This AD results from a report indicating that certain oxygen
cylinder supports may not have been properly heat-treated. We are
issuing this AD to prevent failure of the oxygen cylinder support
under the most critical flight load conditions, which could cause
the oxygen cylinder to come loose and leak oxygen. Leakage of oxygen
could result in oxygen being unavailable for the flightcrew or could
result in a fire hazard in the vicinity of the leakage.
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.
Inspection and Corrective Action
(f) Within 18 months after the effective date of this AD, except
as provided by paragraph (g) of this AD: Inspect the support bracket
of the crew oxygen cylinder installation to determine the
manufacturing date marked on the support, and do the corrective
action as applicable, by doing all of the actions in accordance with
the Accomplishment Instructions of Boeing Special Attention Service
Bulletin 747-35-2114, dated December 19, 2002. Corrective action, if
applicable, must be done before further flight after the inspection.
(g) If the configuration of the crew oxygen cylinder
installation is changed from a one-cylinder to a two-cylinder
configuration: Do the actions required by paragraph (f) of this AD
before further flight after the change in configuration, or within
18 months after the effective date of this AD, whichever is later.
Parts Installation
(h) On or after the effective date of this AD, no person may
install an oxygen cylinder support bracket having part number
65B68258-2 and having a manufacturing date between 10/01/98 and 03/
09/01 inclusive (meaning, a manufacturing date of 10/01/98 or later
and 03/09/01 or earlier).
Alternative Methods of Compliance (AMOCs)
(i)(1) The Manager, Seattle Aircraft Certification Office (ACO),
FAA, has the authority to approve AMOCs for this AD, if requested in
accordance with the procedures found in 14 CFR 39.19.
(2) Before using any AMOC approved in accordance with 14 CFR
39.19 on any airplane to which the AMOC applies, notify the
appropriate principal inspector in the FAA Flight Standards
Certificate Holding District Office.
Issued in Renton, Washington, on December 2, 2005.
