Airworthiness Directives; Israel Aircraft Industries, Ltd., Model 
1125 Westwind Astra Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

[[Page 40884]]

SUMMARY: This amendment adopts a new airworthiness directive (AD) that 
is applicable to certain Israel Aircraft Industries, Ltd., Model 1125 
Westwind Astra series airplanes. This action requires replacing certain 
fuel-immersed electrical harnesses in the fuel tank with modified 
harnesses. This action is necessary to prevent electrical arcing in the 
area of fuel vapors, which could result in a potential explosion and/or 
fire in the fuel tank. This action is intended to address the 
identified unsafe condition.

DATES: Effective August 21, 2001.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of September 5, 2001.
    Comments for inclusion in the Rules Docket must be received on or 
before September 5, 2001.

ADDRESSES: Submit comments in triplicate to the Federal Aviation 
Administration (FAA), Transport Airplane Directorate, ANM-114, 
Attention: Rules Docket No. 2001-NM-202-AD, 1601 Lind Avenue, SW., 
Renton, Washington 98055-4056. Comments may be inspected at this

227-2141; fax (425) 227-1149.

SUPPLEMENTARY INFORMATION: The Civil Aviation Administration of Israel 
(CAAI), which is the airworthiness authority for Israel, recently 
notified the FAA that an unsafe condition may exist on certain Israel 
Aircraft Industries, Ltd., Model 1125 Westwind Astra series airplanes. 
The CAAI advises that certain fuel-immersed electrical harnesses are 
made with Kapton insulation, which can crack over time. Cracked Kapton 
wire insulation could result in electrical arcing in the area of fuel 
vapors and consequent explosion and/or fire in the fuel tank.

Explanation of Relevant Service Information

    Israel Aircraft Industries has issued Astra Alert Service Bulletin 
1125-28A-230, dated March 13, 2001. The alert service bulletin 
describes procedures for removing the left and right transfer valve/
jettison valve electrical harnesses and the forward and aft 
interconnect valve electrical harnesses, and replacing them with 
modified parts. The replacement harnesses are sealed and will therefore 
have no direct contact with fuel. Accomplishment of the actions 
specified in the alert service bulletin is intended to adequately 
address the identified unsafe condition. The CAAI classified this alert 
service bulletin as mandatory and issued Israeli airworthiness 
directive 28-01-02-08, dated May 30, 2001, to ensure the continued 
airworthiness of these airplanes in Israel.

FAA's Conclusions

    This airplane model is manufactured in Israel and is type 
certificated for operation in the United States under the provisions of 
Sec. 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the 
applicable bilateral airworthiness agreement. Pursuant to this 
bilateral airworthiness agreement, the CAAI has kept the FAA informed 
of the situation described above. The FAA has examined the findings of 
the CAAI, reviewed all available information, and determined that AD 
action is necessary for products of this type design that are 
certificated for operation in the United States.

Explanation of Requirements of Rule

    Since an unsafe condition has been identified that is likely to 
exist or develop on other airplanes of the same type design registered 
in the United States, this AD is being issued to prevent electrical 
arcing in the area of fuel vapors, which could result in potential 
explosion and/or fire in the fuel tank. This AD requires accomplishment 
of the actions specified in the alert service bulletin described 
previously.

Determination of Rule's Effective Date

    Since a situation exists that requires the immediate adoption of 
this regulation, it is found that notice and opportunity for prior 
public comment hereon are impracticable, and that good cause exists for 
making this amendment effective in less than 30 days.

Comments Invited

    Although this action is in the form of a final rule that involves 
requirements affecting flight safety and, thus, was not preceded by 
notice and an opportunity for public comment, comments are invited on 
this rule. Interested persons are invited to comment on this rule by 
submitting such written data, views, or arguments as they may desire. 
Communications shall identify the Rules Docket number and be submitted 
in triplicate to the address specified under the caption ADDRESSES. All 
communications received on or before the closing date for comments will 
be considered, and this rule may be amended in light of the comments 
received. Factual information that supports the commenter's ideas and 
suggestions is extremely helpful in evaluating the effectiveness of the 
AD action and determining whether additional rulemaking action would be 
needed.
    Submit comments using the following format:
     Organize comments issue-by-issue. For example, discuss a 
request to change the compliance time and a request to change the 
service bulletin reference as two separate issues.
     For each issue, state what specific change to the AD is 
being requested.
     Include justification (e.g., reasons or data) for each 
request.
    Comments are specifically invited on the overall regulatory, 
economic, environmental, and energy aspects of the rule that might 
suggest a need to modify the rule. All comments submitted will be 
available, both before and after the closing date for comments, in the 
Rules Docket for examination by interested persons. A report that 
summarizes each FAA-public contact concerned with the substance of this 
AD will be filed in the Rules Docket.
    Commenters wishing the FAA to acknowledge receipt of their comments 
submitted in response to this rule must submit a self-addressed, 
stamped postcard on which the following statement is made: ``Comments 
to Docket 2001-NM-202-AD.'' The postcard will be date-stamped and 
returned to the commenter.

Regulatory Impact

    The regulations adopted herein 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. Therefore, it 
is determined that this final rule does not have federalism 
implications under Executive Order 13132.
    The FAA has determined that this regulation is an emergency 
regulation that must be issued immediately to correct an unsafe 
condition in aircraft, and that it is not a ``significant regulatory 
action'' under Executive Order 12866. It has been determined further 
that this action involves an emergency regulation under DOT Regulatory 
Policies and Procedures (44 FR 11034, February 26, 1979). If it is 
determined that this emergency regulation otherwise would be 
significant under DOT Regulatory Policies and Procedures, a final 
regulatory evaluation will be prepared and placed in the Rules Docket. 
A copy of it, if filed, may be obtained from the Rules Docket at the 
location provided under the caption ADDRESSES.

eliminated, the request should include specific proposed actions to 
address it.

    Compliance: Required as indicated, unless accomplished 
previously.
