Discussion
We have received a report indicating
that an unsafe condition may exist on
transport category airplanes equipped
with certain smoke detectors. The
affected smoke detectors are Meggitt
Model 602 smoke detectors approved
under Technical Standard Order (TSO)
TSO–C1C and having certain part
numbers (P/Ns) 8930–( ). Testing
indicated a design discrepancy
involving the operation of these smoke
detectors. During a test on McDonnell
Douglas Model MD–11F airplanes, 31 of
33 smoke detectors ‘‘locked up’’ when
the power to the smoke detectors was
interrupted during power transfer from
the auxiliary power unit (APU) to the
engines. Investigation revealed that the
smoke detector circuit does not meet
power interrupt requirements during a
power transfer between ground power,
APU power, and main engine power
sources on the airplane. When the
smoke detector locks up, the flightcrew
is unaware of the inoperative smoke
detector unless they test the smoke

detection system. The smoke detector
remains inoperative until power to the
unit is cycled off and on. Under these
conditions, the flightcrew would not be
alerted in the event of a fire.
This lock-up condition may also be
produced by electrical power transfer on
other airplanes equipped with an
affected smoke detector. Included in
that group are airplanes listed in the
following table:

Therefore, all of these airplanes may

condition.
Related AD
On January 12, 2005, we issued AD
2005–02–04, amendment 39–13949 (70
FR 3296, January 24, 2005), for all
McDonnell Douglas Model MD–10–10F,
MD–10–30F, MD–11F, DC–10–10F, and
DC–10–30F airplanes. AD 2005–02–04
requires identifying the part number of
the cargo compartment smoke detectors
and, if necessary, revising the
Limitations section of the airplane flight
manual to include procedures for testing
the smoke detection system after the last
engine is started. That AD also provides
for the optional replacement of the
subject smoke detectors with modified
smoke detectors, which would
terminate the operational limitation.
Similar to this new proposed AD, AD
2005–02–04 was prompted by a report
indicating that these smoke detectors
can ‘‘lock up’’ during electrical power
transfer from the APU to the engines.
We issued that AD to identify and
provide corrective action for a
potentially inoperative smoke detector
in the cargo compartment and to ensure
that the flightcrew is alerted in the event
of a cargo compartment fire.
When this new AD becomes effective,
we will rescind AD 2005–02–04.
type design. Therefore, we are
proposing this AD, which would require
accomplishing the actions specified in
the service information described
previously.
Costs of Compliance
It would take about 1 work hour per
airplane, at an average hourly labor rate
of $65, to replace a smoke detector
installed on the airplane. Replacement
parts would be provided at no cost to
the operators. We have been advised
that about 4,637 smoke detectors have
already been replaced. We estimate that
affected smoke detectors are installed on
318 U.S.-registered airplanes. There may
be as many as 28 affected smoke
detectors on an airplane. This proposed
AD could cost as much as $1,820 per
airplane.
Relevant Service Information
We have reviewed Meggitt Safety
Systems Service Information Letter (SIL)
8930–26–01, dated November 8, 2004.
The SIL provides procedures for, among
other things, replacing the affected
smoke detectors with modified smoke
detectors, which is intended to
adequately address the unsafe
condition.
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.
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
Regulatory Findings
We have determined that this
proposed AD would not have federalism

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. See the ADDRESSES
section for a location to examine the
regulatory evaluation.

------------------------------------------------------------------------
Manufacturer Model
------------------------------------------------------------------------
Aerospatiale...................... ATR42 and ATR72 airplanes.
Boeing............................ 727 and 737 airplanes.
McDonnell Douglas................. DC-10-10 and DC-10-10F; DC-10-15; DC-
10-30 and DC-10-30F (KC-10A and KDC-
10); and DC-10-40 and DC-10-40F
airplanes.
MD-10-10F and MD-10-30F airplanes.
MD-11 and MD-11F airplanes.
------------------------------------------------------------------------
Therefore, all of these airplanes may be subject to the identified
unsafe condition.
Related AD
On January 12, 2005, we issued AD 2005-02-04, amendment 39-13949
(70 FR 3296, January 24, 2005), for all McDonnell Douglas Model MD-10-
10F, MD-10-30F, MD-11F, DC-10-10F, and DC-10-30F airplanes. AD 2005-02-
04 requires identifying the part number of the cargo compartment smoke
detectors and, if necessary, revising the Limitations section of the
airplane flight manual to include procedures for testing the smoke
detection system after the last engine is started. That AD also
provides for the optional replacement of the subject smoke detectors
with modified smoke detectors, which would terminate the operational
limitation.
Similar to this new proposed AD, AD 2005-02-04 was prompted by a
report indicating that these smoke detectors can ``lock up'' during
electrical power transfer from the APU to the engines. We issued that
AD to identify and provide corrective action for a potentially
inoperative smoke detector in the cargo compartment and to ensure that
the flightcrew is alerted in the event of a cargo compartment fire.
When this new AD becomes effective, we will rescind AD 2005-02-04.
Relevant Service Information
We have reviewed Meggitt Safety Systems Service Information Letter
(SIL) 8930-26-01, dated November 8, 2004. The SIL provides procedures
for, among other things, replacing the affected smoke detectors with
modified smoke detectors, which 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. Therefore, we are proposing this AD, which
would require accomplishing the actions specified in the service
information described previously.
Costs of Compliance
It would take about 1 work hour per airplane, at an average hourly
labor rate of $65, to replace a smoke detector installed on the
airplane. Replacement parts would be provided at no cost to the
operators. We have been advised that about 4,637 smoke detectors have
already been replaced. We estimate that affected smoke detectors are
installed on 318 U.S.-registered airplanes. There may be as many as 28
affected smoke detectors on an airplane. This proposed AD could cost as
much as $1,820 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 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. See the ADDRESSES section for a location
to examine the regulatory evaluation.
