ACTION: Final rule.
AGENCY:
SUMMARY: The FAA is superseding an
existing airworthiness directive (AD),
which applies to certain SAFT America
Inc. part number (P/N) 021929–000
(McDonnell Douglas P/N 43B034LB02)
and P/N 021904–000 (McDonnell
Douglas P/N 43B034LB03) nickel
cadmium batteries. That AD currently
requires replacing all battery terminal
screws, verifying that the battery
contains design specification cells, and
replacing the cells if the battery contains
non-design specification cells. This new
AD requires an inspection for certain
nickel cadmium batteries and, if
necessary, replacing battery terminal
screws with new hex head bolts and
adding shims. This AD is prompted by
a report of battery screws shearing off
while under normal torque loads. We
are issuing this AD to prevent internal
shorting, arcing, and loss of emergency
battery power due to failed battery
screws, which could result in loss of
emergency power to electrical flight
components or other emergency power
systems required in the event of loss of
the aircraft primary power source.
DATES: This AD becomes effective
August 1, 2005.
The incorporation by reference of a
certain publication listed in the AD is
approved by the Director of the Federal
Register as of August 1, 2005.

SUPPLEMENTARY INFORMATION: The FAA
proposed to amend part 39 of the
Federal Aviation Regulations (14 CFR
part 39) with an AD to supersede AD
98–20–17, amendment 39–10784 (63 FR
50979, September 24, 1998). The
existing AD applies to Part Number (P/
N) 021929–000 (McDonnell Douglas P/
N 43BO34LB02) and P/N 021904–000
(McDonnell Douglas P/N 43BO34LB03)
nickel cadmium batteries manufactured
prior to December 1997 that are
installed on, but not limited to,
McDonnell Douglas DC–9 and MD–80
aircraft, all serial numbers. The
proposed AD, which is applicable to
certain McDonnell Douglas transport
category airplanes, was published in the
Federal Register on December 14, 2004
(69 FR 74461), to require replacing all
battery terminal screws, verifying that
the battery contains design specification
cells, and replacing the cells if the
battery contains non-design
specification cells. The proposed AD
also proposed to require an inspection
for certain nickel cadmium batteries
and, if necessary, replacing battery
terminal screws with new hex head
bolts and adding shims.
Comments
We provided the public the
opportunity to participate in the
development of this AD. We have
considered the comments that have
been submitted on the proposed AD.
Request for a Better Identification of the
Modification
One commenter requests that the
proposed AD provide a better way of
identifying the modification. The
PO 00000
Frm 00016
Fmt 4700
Sfmt 4700
commenter states that identifying the
modification with a sticker, as specified
in SAFT Mandatory Service Bulletin
01–02, Revision 2, dated August 11,
2003, makes it difficult for airlines to
track compliance. The commenter notes
that stickers have been known to come
unglued in the presence of water, acid,
and heat, all of which exist around
battery locations. If a sticker becomes
unglued and lost, this gives the
appearance of non-compliance to the
AD. The commenter suggests requiring
a P/N change on the data plate by
simply adding a letter to the existing P/
N.
We do not agree that a P/N change on
the data plate is necessary in this case.
Although we acknowledge that stickers
may come unglued, the modification
sticker is merely a secondary indication
of compliance. We have determined
that, for the purposes of this AD,
installation of a compliance sticker, as
specified in SAFT Mandatory Service
Bulletin 01–02, Revision 2, dated
August 11, 2003 (referenced as an
additional source of service information
in Boeing Alert Service Bulletin DC9–
24A195, dated December 4, 2003), is not
necessary. We find that recording the
installation of the modified battery in
the airplane maintenance records, as
required by section 91.417 of the
Federal Aviation Regulations, provides
an adequate means for operators to track
AD compliance. Therefore, we have
revised paragraph (f)(2)(ii) of this AD to
specify that installing a sticker is not
required.
Request to Correct Reference to Certain
P/Ns
One commenter requests that two P/
Ns be corrected. The commenter
explains that certain P/Ns, as identified
in the proposed AD, contain the letter
‘‘O’’ instead of the number ‘‘0.’’ The P/
Ns should be 43B034LB02 and
43B034LB03.
We agree and have revised the AD
accordingly.
Editorial Changes
We have added a new Note 2 to the
AD to reiterate, as specified in the
preamble of the proposed AD, that
Boeing Alert Service Bulletin DC9–
24A195, dated December 4, 2003, refers
to SAFT Service Bulletin 01–02,
Revision 2, dated August 11, 2003, as an
additional source of service information
for accomplishing the modification.
Conclusion
We have carefully reviewed the
available data, including the comments
that have been submitted, and
determined that air safety and the
E:\FR\FM\27JNR1.SGM
27JNR1
Federal Register / Vol. 70, No. 122 / Monday, June 27, 2005 / Rules and Regulations
public interest require adopting the AD
with the changes described previously.
We have determined that these changes
will neither increase the economic
burden on any operator nor increase the
scope of the AD.
Costs of Compliance
There are about 1,828 airplanes
worldwide of the affected design. This
AD will affect about 1,087 airplanes of
U.S. registry.
The required inspection to determine
if certain SAFT batteries are installed
will 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 actions
specified in this AD for U.S. operators
is $70,655, 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 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.

Inspection for SAFT Nickel Cadmium
Battery
(f) Within 18 months after the effective
date of this AD, perform a general visual
inspection to determine if a nickel cadmium
battery having P/N 021904–000 (Type
43B034LB03) or P/N 021929–000 (Type
43B034LB02) is installed, in accordance with
Boeing Alert Service Bulletin (ASB) DC9–
24A195, dated December 4, 2003.
(1) If neither P/N is installed, no further
action is required by this paragraph.
(2) If either P/N is installed, before further
flight, inspect the battery to determine if the
battery code date is before May 2003, in
accordance with the ASB.
(i) If the battery code is dated May 2003 or
later, no further action is required by this
paragraph.
(ii) If the battery code is dated before May
2003, before further flight: With the
exception that a sticker is not required to be
installed, modify the battery in accordance
with the ASB.
Note 1: For the purposes of this AD, a
general visual inspection is ‘‘a visual
examination of a interior or exterior area,
installation or assembly to detect obvious
damage, failure or irregularity. This level of
inspection is made from within touching
distance unless otherwise specified. A mirror
may be necessary to ensure visual access to
all surfaces in the inspection area. This level
of inspection is made under normal available
lighting conditions such as daylight, hangar
lighting, flashlight or drop-light and may
require removal or opening of access panels
or doors. Stands, ladders or platforms may be
required to gain proximity to the area being
checked.’’

SUPPLEMENTARY INFORMATION: A
proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) to
include an airworthiness directive (AD)
that is applicable to certain Boeing
Model 777–200 and –300 series
airplanes was published as a
supplemental notice of proposed
rulemaking (NPRM) in the Federal
Register on January 5, 2005 (70 FR 737).
That action proposed to require a onetime inspection of the clevis end of the
vertical tie rods that support the center
stowage bins to measure the exposed
thread, installation of placards that
advise of weight limits for certain
electrical racks, a one-time inspection
and records check to determine the
amount of weight currently installed in
those electrical racks, corrective actions,
and replacement of the vertical tie rods
for the center stowage bins or electrical
racks with new improved tie rods, as
applicable.
Comments
Interested persons have been afforded
an opportunity to participate in the
making of this amendment. Due
consideration has been given to the
comments received.
Support for the Supplemental NPRM
Two commenters support the
supplemental NPRM. One of these
commenters states that the applicable
requirements for its 19 affected
PO 00000
Frm 00018
Fmt 4700
Sfmt 4700
airplanes will take 13 work hours to
accomplish, with a parts cost of $2,072
per airplane. This is consistent with the
costs estimated in the supplemental
NPRM.
Request To Extend Compliance Time
for Weight Inspection/Records Check
One commenter requests that we
revise paragraph (d)(3) of the
supplemental NPRM to extend the
compliance time for accomplishing the
inspection and records check to
determine the weight of equipment
installed in the subject electrical racks.
The commenter notes that, by the time
the AD is issued, it will have
accomplished the actions specified in
paragraphs (d)(1) and (d)(2) of the
supplemental NPRM in accordance with
the referenced service bulletin.
However, it will not have accomplished
the actions specified in paragraph (d)(3)
of the supplemental NPRM because
those actions are not specified in the
service bulletin. The commenter
requests that compliance time language
similar to that in paragraph (a)(2)(i) of
the supplemental NPRM be added to
paragraph (d)(3). (Paragraph (a)(2)(i) of
the supplemental NPRM gives a
compliance time of up to 12 months
after the effective date of the AD for
checking the weight installed in certain
electrical racks on airplanes on which
the placard installation specified in
paragraph (a)(1) has been accomplished
before the effective date of the AD.)
We concur. The actions in paragraph
(d)(3) of this AD are similar to those in
paragraph (a)(2), and the compliance
time should also be similar.
Accordingly, we have revised paragraph
(d)(3) of this AD, and added paragraphs
(d)(3)(i) and (d)(3)(ii) to this AD, to
allow up to 12 months for
accomplishing the weight check on
airplanes on which the actions in
paragraphs (d)(1) and (d)(2) of this AD
have been accomplished before the
effective date of this AD.
Request To Clarify Credit for Actions
Accomplished Previously
The same commenter states that
paragraph (e), ‘‘Actions Accomplished
Previously,’’ contradicts the rest of the
supplemental NPRM. The commenter
states that paragraph (e) implies that no
further work is necessary if a previous
revision of the service bulletin was
accomplished before the effective date
of the AD. The commenter states that
this would mean that the weighing of
electrical racks, which is not referenced
in the service bulletins, would not be
done.
We do not agree. Paragraph (e) states
that actions accomplished before the

installed on, but not limited to, McDonnell Douglas DC-9 and MD-80
aircraft, all serial numbers. The proposed AD, which is applicable to
certain McDonnell Douglas transport category airplanes, was published
in the Federal Register on December 14, 2004 (69 FR 74461), to require
replacing all battery terminal screws, verifying that the battery
contains design specification cells, and replacing the cells if the
battery contains non-design specification cells. The proposed AD also
proposed to require an inspection for certain nickel cadmium batteries
and, if necessary, replacing battery terminal screws with new hex head
bolts and adding shims.
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the comments that have been
submitted on the proposed AD.
Request for a Better Identification of the Modification
One commenter requests that the proposed AD provide a better way of
identifying the modification. The commenter states that identifying the
modification with a sticker, as specified in SAFT Mandatory Service
Bulletin 01-02, Revision 2, dated August 11, 2003, makes it difficult
for airlines to track compliance. The commenter notes that stickers
have been known to come unglued in the presence of water, acid, and
heat, all of which exist around battery locations. If a sticker becomes
unglued and lost, this gives the appearance of non-compliance to the
AD. The commenter suggests requiring a P/N change on the data plate by
simply adding a letter to the existing P/N.
We do not agree that a P/N change on the data plate is necessary in
this case. Although we acknowledge that stickers may come unglued, the
modification sticker is merely a secondary indication of compliance. We
have determined that, for the purposes of this AD, installation of a
compliance sticker, as specified in SAFT Mandatory Service Bulletin 01-
02, Revision 2, dated August 11, 2003 (referenced as an additional
source of service information in Boeing Alert Service Bulletin DC9-
24A195, dated December 4, 2003), is not necessary. We find that
recording the installation of the modified battery in the airplane
maintenance records, as required by section 91.417 of the Federal
Aviation Regulations, provides an adequate means for operators to track
AD compliance. Therefore, we have revised paragraph (f)(2)(ii) of this
AD to specify that installing a sticker is not required.
Request to Correct Reference to Certain P/Ns
One commenter requests that two P/Ns be corrected. The commenter
explains that certain P/Ns, as identified in the proposed AD, contain
the letter ``O'' instead of the number ``0.'' The P/Ns should be
43B034LB02 and 43B034LB03.
We agree and have revised the AD accordingly.
Editorial Changes
We have added a new Note 2 to the AD to reiterate, as specified in
the preamble of the proposed AD, that Boeing Alert Service Bulletin
DC9-24A195, dated December 4, 2003, refers to SAFT Service Bulletin 01-
02, Revision 2, dated August 11, 2003, as an additional source of
service information for accomplishing the modification.
Conclusion
We have carefully reviewed the available data, including the
comments that have been submitted, and determined that air safety and
the
[[Page 36825]]
public interest require adopting the AD with the changes described
previously. We have determined that these changes will neither increase
the economic burden on any operator nor increase the scope of the AD.
Costs of Compliance
There are about 1,828 airplanes worldwide of the affected design.
This AD will affect about 1,087 airplanes of U.S. registry.
The required inspection to determine if certain SAFT batteries are
installed will 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 actions specified in this AD for U.S. operators is $70,655, 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 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. See the ADDRESSES section for a location to
examine the regulatory evaluation.

Note 1:
For the purposes of this AD, a general visual inspection is ``a
visual examination of a interior or exterior area, installation or
assembly to detect obvious damage, failure or irregularity. This
level of inspection is made from within touching distance unless
otherwise specified. A mirror may be necessary to ensure visual
access to all surfaces in the inspection area. This level of
inspection is made under normal available lighting conditions such
as daylight, hangar lighting, flashlight or drop-light and may
require removal or opening of access panels or doors. Stands,
ladders or platforms may be required to gain proximity to the area
being checked.''
Note 2:
Boeing Alert Service Bulletin DC9-24A195, dated December 4,
