Friday, June 30, 2006
This section of the FEDERAL REGISTER
contains notices to the public of the proposed
issuance of rules and regulations. The
purpose of these notices is to give interested
persons an opportunity to participate in the
rule making prior to the adoption of the final
rules.

Allowances and Differentials
patrol officers, and medical personnel.
Under 5 U.S.C. 5902, OPM may, from
time to time, adjust the maximum
uniform allowance granted to
employees for the cost of their uniforms.
The maximum uniform allowance rate
has not been increased since 1991. The
Producer Price Index—Commodities
(Seasonally Adjusted) increased
approximately 24 percent between
January 1991 and January 2005.
Therefore, we are proposing to revise
the regulations at 5 CFR 591.103 to
increase the maximum annual uniform
allowance rate from $400 to $500.
Office of Personnel
Management.
ACTION: Proposed rule with request for
comments.
E.O. 12866, Regulatory Review
SUMMARY: The Office of Personnel
Management is issuing proposed
regulations to increase the maximum
annual uniform allowance rate. When
civilian Federal employees are required
to wear a uniform in the performance of
their duties, agencies must pay a
uniform allowance or furnish a uniform.
Under the proposed rule, the maximum
annual uniform allowance rate would be
increased from $400 to $500.
DATES: Comments must be received on
or before August 29, 2006.
ADDRESSES: Send or deliver written
comments to Jerome D. Mikowicz,

SUPPLEMENTARY INFORMATION: The Office
of Personnel Management (OPM) is
proposing to increase the maximum
annual uniform allowance rate. Under 5
U.S.C. 5901(a), when civilian Federal
employees are required to wear a
uniform in the performance of their
duties, agencies must pay a uniform
allowance not to exceed $400 a year or
furnish a uniform at a cost not to exceed
$400. Many agencies provide uniform
allowances to employees, such as police
officers, firefighters, customs and border

ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
SUMMARY: The FAA proposes to
supersede an existing airworthiness
directive (AD) that applies to certain
Boeing Model 767–200, –300, and
–300F series airplanes. The existing AD
currently requires an inspection of
visually accessible areas for indications
of overheating of the heater tape
attached to the potable water fill and
drain lines in the forward and aft cargo
compartments, exposed foam insulation
or missing or damaged protective tape
around the potable water fill and drain
lines, and debris or contaminants on or
near the potable water fill and drain
lines. That AD also requires corrective
action, as necessary. This proposed AD
would require repetitive inspections of
the forward and aft cargo compartments,
as applicable, for discrepancies of the
potable water supply and gray water
drain lines; and applicable corrective
actions if necessary. This proposed AD
also would require replacing the heater
tapes on the potable water supply and
gray water drain lines of the forward
and aft cargo compartments, as
applicable, with new ribbon heaters,
which would end the repetitive
inspections. This proposed AD results
from a report of a fire in the aft cargo
compartment. We are proposing this AD
to prevent overheating of the heater tape
on potable water fill and drain lines,
which may ignite accumulated debris or
contaminants on or near the potable
water fill and drain lines, resulting in a
fire in the airplane.
DATES: We must receive comments on
this proposed AD by August 14, 2006.

Discussion
On May 29, 2002, we issued AD
2002–11–11, amendment 39–12772 (67
FR 39265, June 7, 2002), for certain
Boeing Model 767–200, –300, and
–300F series airplanes. That AD requires
an inspection of visually accessible
areas for indications of overheating of
the heater tape attached to the potable
water fill and drain lines in the forward
and aft cargo compartments, exposed
foam insulation or missing or damaged
protective tape around the potable water
fill and drain lines, and debris or
contaminants on or near the potable
water fill and drain lines. That AD also
requires correction action, as necessary.
That AD resulted from a report of a fire
in the aft cargo compartment. We issued
that AD to prevent overheating of the
heater tape on potable water fill and
drain lines, which may ignite
accumulated debris or contaminants on
or near the potable water fill and drain
lines, resulting in a fire in the airplane.
Actions Since Existing AD Was Issued
In the preamble to AD 2002–11–11,
we indicated that the actions required
by that AD were considered ‘‘interim
action,’’ and that further rulemaking
action was being considered. We now
have determined that further
rulemaking action is indeed necessary,
and this proposed AD follows from that
determination.
Relevant Service Information
We have reviewed Boeing Service
Bulletin 767–30A0038, Revision 2,
dated February 23, 2006. Revision 2 of
the service bulletin describes
procedures for repetitive general visual
inspections of the forward and aft cargo
compartments, as applicable, for
discrepancies of the potable water
supply and gray water drain lines; and
applicable corrective actions if
necessary. The discrepancies include:
foreign object debris (FOD),
contamination, heat damage, exposed
foam insulation, and missing or
PO 00000
Frm 00002
Fmt 4702
Sfmt 4702
damaged protective tape of all heater
tape. The applicable corrective actions
include:
• Removing FOD or contamination;
• Replacing damaged heater tape with
new heater tape;
• Disconnecting damaged heater tape;
• Applying a continuous wrap of
external protective tape to cover the
foam insulation; and
• Fully covering the heater tape with
external protective tape.
In addition, the service bulletin
describes procedures for replacing the
heater tapes on the potable water supply
and gray water drain lines of the
forward and aft cargo compartments, as
applicable, with new Adel Wiggins
ribbon heaters, which ends the need for
the repetitive inspections.
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 develop on
other airplanes of the same type design.
For this reason, we are proposing this
AD, which would supersede AD 2002–
11–11 to require accomplishing the
actions specified in the service bulletin
described previously.
Change to Existing AD
AD 2002–11–11 affects Model 767–
200, –300, and –300F series airplanes
with non-fully-enclosed cargo floors in
the lower cargo areas. Since the
issuance of that AD, Boeing has
informed us that the new, improved
heater tapes are being installed on
airplanes, line numbers 919 and higher,
in production. Boeing Service Bulletin
767–30A0038, Revision 2, specifies the
current affected airplanes and operators.
In addition, we have determined that
Model 767–300F series airplanes are not
subject to the identified unsafe
condition and were inadvertently
included in the applicability of AD
2002–11–11. Therefore, the applicability
of this proposed AD limits the
applicability of the existing AD to
airplanes identified in Revision 2 of
Boeing Service Bulletin 767–30A0038.
Costs of Compliance
There are about 455 airplanes of the
affected design in the worldwide fleet.
The following table provides the
estimated costs for U.S. operators to
comply with this proposed AD.

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
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.

Discussion
On May 29, 2002, we issued AD 2002-11-11, amendment 39-12772 (67 FR
39265, June 7, 2002), for certain Boeing Model 767-200, -300, and -300F
series airplanes. That AD requires an inspection of visually accessible
areas for indications of overheating of the heater tape attached to the
potable water fill and drain lines in the forward and aft cargo
compartments, exposed foam insulation or missing or damaged protective
tape around the potable water fill and drain lines, and debris or
contaminants on or near the potable water fill and drain lines. That AD
also requires correction action, as necessary. That AD resulted from a
report of a fire in the aft cargo compartment. We issued that AD to
prevent overheating of the heater tape on potable water fill and drain
lines, which may ignite accumulated debris or contaminants on or near
the potable water fill and drain lines, resulting in a fire in the
airplane.
Actions Since Existing AD Was Issued
In the preamble to AD 2002-11-11, we indicated that the actions
required by that AD were considered ``interim action,'' and that
further rulemaking action was being considered. We now have determined
that further rulemaking action is indeed necessary, and this proposed
AD follows from that determination.
Relevant Service Information
We have reviewed Boeing Service Bulletin 767-30A0038, Revision 2,
dated February 23, 2006. Revision 2 of the service bulletin describes
procedures for repetitive general visual inspections of the forward and
aft cargo compartments, as applicable, for discrepancies of the potable
water supply and gray water drain lines; and applicable corrective
actions if necessary. The discrepancies include: foreign object debris
(FOD), contamination, heat damage, exposed foam insulation, and missing
or damaged protective tape of all heater tape. The applicable
corrective actions include:
Removing FOD or contamination;
Replacing damaged heater tape with new heater tape;
Disconnecting damaged heater tape;
Applying a continuous wrap of external protective tape to
cover the foam insulation; and
Fully covering the heater tape with external protective
tape.
In addition, the service bulletin describes procedures for
replacing the heater tapes on the potable water supply and gray water
drain lines of the forward and aft cargo compartments, as applicable,
with new Adel Wiggins ribbon heaters, which ends the need for the
repetitive inspections.
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 develop on other airplanes of the
same type design. For this reason, we are proposing this AD, which
would supersede AD 2002-11-11 to require accomplishing the actions
specified in the service bulletin described previously.
Change to Existing AD
AD 2002-11-11 affects Model 767-200, -300, and -300F series
airplanes with non-fully-enclosed cargo floors in the lower cargo
areas. Since the issuance of that AD, Boeing has informed us that the
new, improved heater tapes are being installed on airplanes, line
numbers 919 and higher, in production. Boeing Service Bulletin 767-
30A0038, Revision 2, specifies the current affected airplanes and
operators. In addition, we have determined that Model 767-300F series
airplanes are not subject to the identified unsafe condition and were
inadvertently included in the applicability of AD 2002-11-11.
Therefore, the applicability of this proposed AD limits the
applicability of the existing AD to airplanes identified in Revision 2
of Boeing Service Bulletin 767-30A0038.
Costs of Compliance
There are about 455 airplanes of the affected design in the
worldwide fleet. The following table provides the estimated costs for
U.S. operators to comply with this proposed AD.

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 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.
