ACTION: Final rule.
AGENCY:
SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for the
McDonnell Douglas airplanes
previously described. This AD requires
replacing the control modules of the fire
detection systems of the propulsion
engines with new, improved control
modules. This AD results from a report
of broken or severed wiring between
engine fire detectors and the fire
detection system control module, which
caused the fire detection system to
become non-functional without
flightcrew awareness. We are issuing
this AD to prevent unannunciated fire
in a propulsion engine, which could
cause injury to flightcrew and
passengers or loss of the airplane.
DATES: This AD becomes effective
March 23, 2007.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in the AD
as of March 23, 2007.

SUPPLEMENTARY INFORMATION:
Examining the Docket
You may examine the airworthiness
directive (AD) docket on the Internet at
https://dms.dot.gov or in person at the
Docket Management Facility office
between 9 a.m. and 5 p.m., Monday
through Friday, except Federal holidays.

(telephone (800) 647–5227) is located on
the plaza level of the Nassif Building at
the street address stated in the
ADDRESSES section.
Discussion
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would
apply to all McDonnell Douglas Model
DC–10–10, DC–10–10F, DC–10–15, DC–
10–30, and DC–10–30F (KC–10A and
KDC–10) airplanes; Model DC–10–40
and DC–10–40F airplanes equipped
with Pratt & Whitney JT9–20 or JT9–20J
engines; and all Model MD–10–10F and
MD–10–30F airplanes. That NPRM was
published in the Federal Register on
October 13, 2006 (71 FR 60448). That
NPRM proposed to require replacing the
control modules of the fire detection
systems of the propulsion engines with
new, improved control modules.
Comments
We provided the public the
opportunity to participate in the
development of this AD. We have
considered the comments received.
Support for the NPRM
FedEx concurs with the NPRM as
written and states its intent to also
modify the fire detection systems of the
auxiliary power units of subject FedEx
airplanes, as described in the service
information mandated by the AD.
Request To Clarify Service Information
Requirement
Hawaiian Airlines requests that we
revise the NPRM to clarify what service
information is acceptable for
compliance with the AD. The
commenter asserts that the NPRM states
that the use of Meggitt Safety Systems
Service Bulletin 26–34, Revision 2,
E:\FR\FM\16FER1.SGM
16FER1
Federal Register / Vol. 72, No. 32 / Friday, February 16, 2007 / Rules and Regulations
dated August 15, 2006, is acceptable for
compliance. However, the commenter
states that, according to Revision 1 and
Revision 2 of the service bulletin, no
further work is required. Therefore, the
commenter inquires whether
compliance with the original issue or
Revision 1 of the service information
will be acceptable.
We partially agree. Although we can
find no statement in Service Bulletin
26–34, Revision 1, dated July 17, 2006
(which is the original issue); or Revision
2; that no further work is required, we
have confirmed that Revision 1 and
Revision 2 are technically identical and
differ only in issues of format and style.
Therefore, we have added new
paragraph (g) to the AD to specify that
actions accomplished before the
effective date of the AD in accordance
with Revision 1 of Service Bulletin 26–
34 are acceptable for compliance with
the requirements of the AD. We have reidentified subsequent paragraphs of the
AD accordingly.
rmajette on PROD1PC67 with RULES
Request To Include Statement of Intent
To Incorporate by Reference
The Modification and Replacement
Parts Association (MARPA) requests
that, during the NPRM stage of AD
rulemaking, the FAA state its intent to
incorporate by reference (IBR) any
relevant service information. MARPA
states that without such a statement in
the NPRM, it is unclear whether the
relevant service information will be
incorporated by reference in the final
rule.
We do not concur with the
commenter’s request. When we
reference certain service information in
a proposed AD, the public can assume
we intend to IBR that service
information, as required by the Office of
the Federal Register. No change to the
AD is necessary in regard to the
commenter’s request.
Request To Post IBR Documents on the
Docket Management System (DMS)
MARPA asserts that IBR documents
should be made available to the public
by publication in the DMS, keyed to the
action that incorporates them. MARPA
therefore requests that such documents
be published in the DMS prior to release
of the final rule.
We do not agree with this request. We
are currently in the process of reviewing
issues surrounding the posting of
service bulletins on the DMS as part of
an AD docket. Once we have thoroughly
examined all aspects of this issue and
have made a final determination, we
will consider whether our current
practice needs to be revised. No change
to the AD is necessary in this regard.

Conclusion
We have carefully reviewed the
available data, including the comments
received, and determined that air safety
and the 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 305 airplanes of the
affected design in the worldwide fleet.
This AD affects about 233 airplanes of
U.S. registry. The required actions take
about 6 work hours per airplane, at an
average labor rate of $80 per work hour.
Required parts cost about $9,900 per
airplane. Based on these figures, the
estimated cost of the AD for U.S.
operators is $2,418,540, or $10,380 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 and placed it in the AD docket.

modifying the left- and right-hand
standby fuel pump switches. This AD
also requires revising the Emergency
and Abnormal Procedures sections of
the airplane flight manual to advise the
flightcrew of the proper procedures to
follow in the event of failure of the
standby fuel pump to shut off. This AD
results from a report of inadvertent
operation of a standby fuel pump due to
an electrical system malfunction. We are
issuing this AD to prevent this
inadvertent operation, which could
result in inadvertent fuel transfer by the
left or right wing fuel system and
subsequent over-limit fuel imbalance
between the left and right wing fuel
loads. This imbalance could affect
lateral control of the airplane which
could result in reduced controllability.

airplanes. That NPRM was published in
the Federal Register on August 16, 2006
(71 FR 47154). That NPRM proposed to
require modifying the left- and righthand standby fuel pump switches. That
NPRM also proposed to require revising
the Emergency and Abnormal
Procedures sections of the airplane
flight manual (AFM) to advise the
flightcrew of the proper procedures to
follow in the event of failure of the
standby fuel pump to shut off.
Comments
We provided the public the
opportunity to participate in the
development of this AD. We have
considered the comments received.
Requests To Withdraw the NPRM
One private citizen states that the
flight department he works for operates
three Learjet Model 35A airplanes and
a Learjet Model 31 airplane. He adds
that the airplanes have never had an
inadvertent operation of the fuel pumps
resulting in an over-limit fuel
imbalance. He also notes that the fuel
crossflow valve must be open in order
to transfer fuel; this requires two
switches to be selected—the standby
fuel pump and the crossflow valve. He
states that even if a standby fuel pump
is inadvertently activated, no fuel will
be transferred unless the crossflow valve
is also open. He concludes that there is
already enough protection in the system
to avoid an over-limit fuel imbalance.

and MD-10-30F airplanes. That NPRM was published in the Federal
Register on October 13, 2006 (71 FR 60448). That NPRM proposed to
require replacing the control modules of the fire detection systems of
the propulsion engines with new, improved control modules.
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the comments received.
Support for the NPRM
FedEx concurs with the NPRM as written and states its intent to
also modify the fire detection systems of the auxiliary power units of
subject FedEx airplanes, as described in the service information
mandated by the AD.
Request To Clarify Service Information Requirement
Hawaiian Airlines requests that we revise the NPRM to clarify what
service information is acceptable for compliance with the AD. The
commenter asserts that the NPRM states that the use of Meggitt Safety
Systems Service Bulletin 26-34, Revision 2,
[[Page 7567]]
dated August 15, 2006, is acceptable for compliance. However, the
commenter states that, according to Revision 1 and Revision 2 of the
service bulletin, no further work is required. Therefore, the commenter
inquires whether compliance with the original issue or Revision 1 of
the service information will be acceptable.
We partially agree. Although we can find no statement in Service
Bulletin 26-34, Revision 1, dated July 17, 2006 (which is the original
issue); or Revision 2; that no further work is required, we have
confirmed that Revision 1 and Revision 2 are technically identical and
differ only in issues of format and style. Therefore, we have added new
paragraph (g) to the AD to specify that actions accomplished before the
effective date of the AD in accordance with Revision 1 of Service
Bulletin 26-34 are acceptable for compliance with the requirements of
the AD. We have re-identified subsequent paragraphs of the AD
accordingly.
Request To Include Statement of Intent To Incorporate by Reference
The Modification and Replacement Parts Association (MARPA) requests
that, during the NPRM stage of AD rulemaking, the FAA state its intent
to incorporate by reference (IBR) any relevant service information.
MARPA states that without such a statement in the NPRM, it is unclear
whether the relevant service information will be incorporated by
reference in the final rule.
We do not concur with the commenter's request. When we reference
certain service information in a proposed AD, the public can assume we
intend to IBR that service information, as required by the Office of
the Federal Register. No change to the AD is necessary in regard to the
commenter's request.
Request To Post IBR Documents on the Docket Management System (DMS)
MARPA asserts that IBR documents should be made available to the
public by publication in the DMS, keyed to the action that incorporates
them. MARPA therefore requests that such documents be published in the
DMS prior to release of the final rule.
We do not agree with this request. We are currently in the process
of reviewing issues surrounding the posting of service bulletins on the
DMS as part of an AD docket. Once we have thoroughly examined all
aspects of this issue and have made a final determination, we will
consider whether our current practice needs to be revised. No change to
the AD is necessary in this regard.
Conclusion
We have carefully reviewed the available data, including the
comments received, and determined that air safety and the 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 305 airplanes of the affected design in the
worldwide fleet. This AD affects about 233 airplanes of U.S. registry.
The required actions take about 6 work hours per airplane, at an
average labor rate of $80 per work hour. Required parts cost about
$9,900 per airplane. Based on these figures, the estimated cost of the
AD for U.S. operators is $2,418,540, or $10,380 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 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, Incorporation by
reference, Safety.
Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
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]
0
2. The Federal Aviation Administration (FAA) amends Sec. 39.13 by
adding the following new airworthiness directive (AD):
2007-04-17 McDonnell Douglas: Amendment 39-14949. Docket No. FAA-
2006-26049; Directorate Identifier 2006-NM-177-AD.
Effective Date
(a) This AD becomes effective March 23, 2007.
Affected ADs
(b) None.
Applicability
(c) This AD applies to McDonnell Douglas airplanes, certificated
in any category; as specified in paragraphs (c)(1), (c)(2), and
(c)(3) of this AD.
(1) All Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30, and DC-
10-30F (KC-10A and KDC-10) airplanes;
(2) Model DC-10-40 and DC-10-40F airplanes equipped with Pratt &
Whitney JT9-20 or JT9-20J engines; and
(3) All Model MD-10-10F and MD-10-30F airplanes.
Unsafe Condition
(d) This AD results from a report of broken or severed wiring
between engine fire detectors and the fire detection system control
module, which caused the fire detection system to become non-
functional without flightcrew awareness. We are issuing this AD to
prevent unannunciated fire in a propulsion engine, which could cause
injury to flightcrew and passengers or loss of the airplane.
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.
