and Midland-Ross Corporation)
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding Airworthiness Directive (AD) 96-20-07,
which applies to certain B-Series Combustion Heaters Models B1500,
B2030, B3040, and B4050 that are installed on airplanes. AD 96-20-07
currently requires you to repetitively test (pressure decay) the
combustion tube and overhaul any heater that does not pass any test. AD
96-20-07 also requires you to repetitively test the operation of the
combustion air pressure switch and replace any combustion pressure
switch that does not pass one of the tests. As a terminating action for
the repetitive test requirements of AD 96-20-07, you could install a
new ceramic-coated combustion tube and an improved design combustion
air pressure switch. This AD is the result of reports that the new
ceramic-coated combustion tubes are subject to the same distress as the
non-ceramic coated combustion tubes. Consequently, this AD retains the
repetitive testing requirements of AD 96-20-07, removes the terminating
action for the combustion tube, and adds Models B2500, B3500, and B4500
to the applicability section. We are issuing this AD to prevent
combustion by-products (carbon-monoxide exhaust) and fuel leakage from
the combustion heaters caused by failure of the combustion heater
system. This failure could result in fire or explosion in the airplane
and possible carbon monoxide poisoning of the crew and passengers in
the cabin.
DATES: This AD becomes effective on November 19, 2004.
On November 14, 1996 (61 FR 51357, October 2, 1996), the Director
of the Federal Register approved the incorporation by reference of
JanAero Devices Service Bulletin A-103, dated September 1995.

SUPPLEMENTARY INFORMATION:
Has FAA taken any action to this point? Repeated reports of
failures of the affected heaters prompted us to issue AD 96-20-07,
Amendment 39-9773 (61 FR 51357, October 2, 1996). AD 96-20-07 applies
to JanAero Devices B-Series Combustion Heaters, Models B1500, B2030,
B3040, and B4050 (formerly owned by Janitrol, C&D, FL Aerospace, and
Midland-Ross Corporation), marked as meeting the standards of TSO-C20,
that do not incorporate a ceramic combustion tube and a combustion air
pressure switch, part number (P/N) 94E42, that are installed on
airplanes. AD 96-20-07 currently requires the following:
Repetitively inspecting (pressure decay test) the
combustion tube of the heater;
Overhauling the heater and replacing the combustion tube
with a serviceable tube or replacing the heater assembly if the heater
fails any of these tests;
Repetitively testing the operation of the combustion air
pressure switch; and
Replacing the switch with one of the same design or with
one of improved design, P/N 94E42, if the combustion air pressure
switch fails any of these tests.
Replacing the heater assembly with a new or rebuilt heater assembly
that incorporates a ceramic combustion tube terminates the repetitive
inspection requirements.
Replacing the combustion air pressure switch with a P/N 94E42
switch terminates the repetitive operational test requirements.
As an alternative method of compliance to AD 96-20-07, you may
disable the heater.
B-Series Combustion Heaters, Models B2500, B3500, and B4500 were
exempt from AD 96-20-07 because they incorporated a ceramic-coated
combustion tube and a new combustion air pressure switch, P/N 94E42.
You must do the actions in AD 96-20-07 following JanAero Devices
Service Bulletin A-103, dated September 1995.
What has happened since AD 96-20-07 to initiate this action? We
have received reports that the ceramic-coated combustion tubes are
subject to some of the same distress noted in the non-ceramic coated
combustion tubes. The ceramic-coated combustion tubes were incorporated
as a product improvement in AD 96-20-07 as a terminating action for the
repetitive pressure decay.
What is the potential impact if FAA took no action? If not detected
and corrected, failure of the combustion heaters could cause combustion
by-products (carbon-monoxide exhaust) and fuel to leak. This failure
could result in fire or explosion in the airplane and possible carbon
monoxide poisoning of the crew and passengers in the cabin.
FAA's Determination and Requirements of the AD
What has FAA decided? We have evaluated all pertinent information
and identified an unsafe condition that is likely to exist or develop
on other products of this same type design.
Since the unsafe condition described previously is likely to exist
or develop on other airplanes that have certain B-Series Combustion
Heaters Models B1500, B2030, B2500, B3040, B3500, B4050, and B4500
installed, we are issuing this AD to prevent combustion by-products
(carbon-monoxide exhaust) and fuel leakage from the combustion heaters
caused by failure of the combustion heater system. This failure could
result in fire or explosion in the airplane and possible carbon
monoxide poisoning of the crew and passengers in the cabin.
What does this AD require? This AD supersedes AD 96-20-07 with a
new AD that retains the repetitive pressure decay test of the
combustion tube and the repetitive operational test of the combustion
air pressure switch from AD 96-20-07. This AD also removes the
terminating action for the repetitive testing requirements of the
combustion tube and adds B-Series Combustion Heaters, Models B2500,
B3500, and B4500 to the applicability section.
In preparing this rule, we contacted type clubs and aircraft
operators to get technical information and information on operational
and economic impacts. We did not receive any information through these
contacts. If received, we would have included a discussion of any
information that may have influenced this action in the rulemaking
docket.
How does the revision to 14 CFR part 39 affect this AD? On July 10,
2002, we published a new version of 14 CFR part 39 (67 FR 47997, July
22, 2002), which governs FAA's AD system. This regulation now includes
material that relates to altered products, special flight permits, and
alternative methods of compliance. This material previously was
included in each individual AD. Since this material is included in 14
CFR part 39, we will not include it in future AD actions.
Comments Invited
Will I have the opportunity to comment before you issue the rule?
This AD is a final rule that involves requirements affecting flight
safety and was not preceded by notice and an opportunity for public
comment; however, we invite you to submit any written relevant data,
views, or arguments regarding this AD. Send your comments to an address
listed under ADDRESSES. Include ``Docket No. FAA-2004-19118;
Directorate Identifier 2004-CE-25-AD'' in the subject line of your

comments, send us a self-addressed, stamped postcard with the docket
number written on it; we will date-stamp your postcard and mail it back
to you. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of the rule that might
suggest a need to modify it. If a person contacts us through a non-
written communication, and that contact relates to a substantive part
of this AD, we will summarize the contact and place the summary in the
docket. We will consider all comments received by the closing date and
may amend the AD in light of those comments.
Regulatory Findings
Will this AD impact various entities? 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.
Will this AD involve a significant rule or regulatory action? 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 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 summary of the costs to comply with this AD and
placed it in the AD Docket. You may get a copy of this summary by
sending a request to us at the address listed under ADDRESSES. Include
``AD Docket FAA-2004-19118; Directorate Identifier 2004-CE-25-AD'' in
your request.
