Federal Register / Vol. 69, No. 204 / Friday, October 22, 2004 / Rules and Regulations 61993

The threat levels identified above are 

the result of an FAA review of existing 

studies on the subject of HIRF, in light 

of the ongoing work of the 

Electromagnetic Effects Harmonization 

Working Group of the Aviation 

Rulemaking Advisory Committee. 

Applicability 

As discussed above, these special 

conditions are applicable to DassaultBreguet Model Falcon 10 airplanes 

modified by Flight Test Associates 

Incorporated. Should Flight Test 

Associates Incorporated apply at a later 

date for a supplemental type certificate 

to modify any other model included on 

Type Certificate No. A33EU to 

incorporate the same or similar novel or 

unusual design feature, these special 

conditions would apply to that model as 

well as under the provisions of 14 CFR 

21.101. 

Conclusion 

This action affects only certain novel 

or unusual design features on DassaultBreguet Model Falcon 10 airplanes 

modified by Flight Test Associates 

Incorporated. It is not a rule of general 

applicability and affects only the 

applicant which applied to the FAA for 

approval of these features on the 

airplane. 

The substance of the special 

conditions for these airplanes has been 

subjected to the notice and comment 

procedure in several prior instances and 

has been derived without substantive 

change from those previously issued. 

Because a delay would significantly 

affect the certification of the airplane, 

which is imminent, the FAA has 

determined that prior public notice and 

comment are unnecessary and 

impracticable, and good cause exists for 

adopting these special conditions upon 

issuance. The FAA is requesting 

comments to allow interested persons to 

submit views that may not have been 

submitted in response to the prior 

opportunities for comment described 

above.

The Special Conditions

■ Accordingly, pursuant to the authority 

delegated to me by the Administrator, 

the following special conditions are 

issued as part of the supplemental type 

certification basis for the DassaultBreguet Model Falcon 10 airplanes 

modified by Flight Test Associates 

Incorporated: 

1. Protection From Unwanted Effects 

of High-Intensity Radiated Fields 

(HIRF). Each electrical and electronic 

system that performs critical functions 

must be designed and installed to 

ensure that the operation and 

operational capability of these systems 

to perform critical functions are not 

adversely affected when the airplane is 

exposed to high intensity radiated 

fields. 

2. For the purpose of these special 

conditions, the following definition 

applies: 

Critical Functions: Functions whose 

failure would contribute to or cause a 

failure condition that would prevent the 

continued safe flight and landing of the 

airplane.

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 nonceramic 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 byproducts (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 BSeries 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. If you want us to 

acknowledge receipt of your mailed 

comments, send us a self-addressed, 

stamped postcard with the docket 

number written on it; we will datestamp 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.

N 94E42 do not need to conduct an 

operational test of the combustion air 

pressure switch. The part number is inkstamped on the side of these combustion air 

pressure switches.

What Is the Unsafe Condition Presented in 

This AD? 

(d) This AD is the result of reports that the 

new ceramic-coated combustion tubes are 

subject to the same distress as the nonceramic coated combustion tubes. We are 

issuing this AD to prevent combustion byproducts (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 Must I Do To Address This Problem? 

(e) For airplanes with an affected B-Series 

combustion heater that does not incorporate 

an extended-life ceramic-coated combustion 

tube, do the following:

Actions Compliance Procedures 

(1) Perform the following: 

(i) Using a pressure decay test, inspect the 

combustion tube of the heater; and 

(ii) Conduct an operational test of the combustion air pressure switch. In some applications, 

the air pressure switch is remotely mounted 

on the airframe and not on the heater. Regardless of where the air pressure switch is 

located, the operational test requirements of 

this AD still apply. 

(iii) If an air pressure switch, part number 

94E42 is currently installed, the operational 

test is not required. 

For airplanes with 450 or more heater hours 

time-in-service (TIS) accumulated on an installed heater since new installation or 

since the last overhaul: Within the next 50 

hours TIS or 12 calendar months after November 14, 1996 (the effective date of AD 

96–20–07), whichever occurs first, unless 

already done.

For airplanes with less than 450 heater hours 

TIS accumulated on an installed heater 

since new installation or since the last overhaul: Upon the accumulation of 500 heater 

hours TIS or within the next 12 calendar 

months after November 14, 1996 (the effective date of AD 96–20–07), whichever occurs first, unless already done. 

After doing the initial inspection and operational test: Repetitively inspect the combustion tube and perform the operational 

test of the air pressure switch thereafter at 

intervals not-to-exceed 100 heater hours 

TIS or 24 calendar months, whichever occurs first. 

Follow the applicable instructions in Janitrol 

Maintenance and Overhaul Manual 24E25–

1. 

(2) After each inspection required in paragraph 

(e)(1) of this AD, if the heater does not pass 

the pressure decay test, overhaul the heater 

and replace the combustion tube with a serviceable tube or replace the heater assembly.

Prior to further flight after the inspection required in paragraph (e)(1) of this AD in 

which the combustion tube fails. After the 

heater is overhauled or replaced with a new

14 CFR Part 95 

[Docket No. 30427; Amdt. No. 451] 

IFR Altitudes; Miscellaneous 

Amendments

AGENCY: Federal Aviation 

Administration (FAA), DOT.

ACTION: Final rule.

SUMMARY: This amendment adopts 

miscellaneous amendments to the 

required IFR (instrument flight rules) 

altitudes and changeover points for 

certain Federal airways, jet routes, or 

direct routes for which a minimum or 

maximum en route authorized IFR 

altitude is prescribed. This regulatory 

action is needed because of changes 

occurring in the National Airspace 

System. These changes are designed to 

provide for the safe and efficient use of 

the navigable airspace under instrument 

conditions in the affected areas.

EFFECTIVE DATE: 0901 UTC, November 

25, 2004.

SUPPLEMENTARY INFORMATION: This 

amendment to part 95 of the Federal 

Aviation Regulations (14 CFR part 95) 

amends, suspends, or revokes IFR 

altitudes governing the operation of all 

aircraft in flight over a specified route 

or any portion of that route, as well as 

the changeover points (COPs) for 

Federal airways, jet routes, or direct 

routes as prescribed in part 95. 

The Rule 

The specified IFR altitudes, when 

used in conjunction with the prescribed 

changeover points for those routes, 

ensure navigation aid coverage that is 

adequate for safe flight operations and 

free of frequency interference. The 

reasons and circumstances that create 

the need for this amendment involve 

matters of flight safety and operational 

efficiency in the National Airspace 

System, are related to published 

aeronautical charts that are essential to 

the user, and provide for the safe and 

efficient use of the navigable airspace. 

In addition, those various reasons or 

circumstances require making this 

amendment effective before the next 

scheduled charting and publication date 

of the flight information to assure its 

timely availability to the user. The 

effective date of this amendment reflects 

those considerations. In view of the 

close and immediate relationship 

between these regulatory changes and 

safety in air commerce, I find that notice 

and public procedure before adopting 

this amendment are impracticable and 

contrary to the public interest and that 

good cause exists for making the 

amendment effective in less than 30 

days. 

Conclusion 

The FAA has determined that this 

regulation only involves an established
