Discussion

    The Civil Aviation Administration of Israel (CAAI), which is the 
airworthiness authority for Israel, notified the FAA that an unsafe 
condition may exist on certain Israel Aircraft Industries, Ltd., Model 
Galaxy airplanes. The CAAI advises that early fatigue failure of the 
fasteners that support the aft pickup fittings of the horizontal 
stabilizer can occur. This failure was detected during a fatigue test 
conducted by the manufacturer. Such fatigue failure, if not corrected, 
could result in reduced structural integrity of the empennage.

Explanation of Relevant Service Information

    Israel Aircraft Industries has issued GALAXY Service Bulletin 
GALAXY-55-008, dated March 23, 2000, which describes procedures for 
removing certain existing HI-LOKS or life-limited fasteners in the aft 
pickup fittings of the horizontal stabilizer, and replacing those 
fasteners with improved non-life-limited fasteners. The replacement 
involves measuring the diameter of the bolt shank, reaming holes, 
inspecting to detect cracks using an eddy current technique, and 
installing certain new bolts. Accomplishment of the actions specified 
in the service bulletin is intended to adequately address the 
identified unsafe condition. The CAAI classified this service bulletin 
as mandatory and issued Israeli airworthiness directive 55-00-04-05, 
dated April 27, 2000, in order to assure 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 
section 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 Proposed 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, the proposed AD would require accomplishment of 
the actions specified in the service bulletin described previously.

Cost Impact

    The FAA estimates that 10 Model GALAXY airplanes of U.S. registry

[[Page 64632]]

would be affected by this proposed AD, that it would take approximately 
16 work hours per airplane to accomplish the proposed actions, and that 
the average labor rate is $60 per work hour. Required parts would cost 
approximately $250 per airplane. Based on these figures, the cost 
impact of the proposed AD on U.S. operators is estimated to be $12,100, 
or $1,210 per airplane.
    The cost impact figure discussed above is based on assumptions that 
no operator has yet accomplished any of the proposed requirements of 
this AD action, and that no operator would accomplish those actions in 
the future if this AD were not adopted. The cost impact figures 
discussed in AD rulemaking actions represent only the time necessary to 
perform the specific actions actually required by the AD. These figures 
typically do not include incidental costs, such as the time required to 
gain access and close up, planning time, or time necessitated by other 
administrative actions.

Regulatory Impact

    The regulations proposed herein 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. Therefore, it 
is determined that this proposal would not have federalism implications 
under Executive Order 13132.
    For the reasons discussed above, I certify that this 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) if promulgated, 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. A copy of the draft 
regulatory evaluation prepared for this action is contained in the 
Rules Docket. A copy of it may be obtained by contacting the Rules 
Docket at the location provided under the caption ADDRESSES.

The Proposed Amendment

    Accordingly, pursuant to the authority delegated to me by the 
Administrator, the Federal Aviation Administration proposes to amend 
part 39 of the Federal Aviation Regulations (14 CFR part 39) as 
follows:

PART 39--AIRWORTHINESS DIRECTIVES

    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]

    2. Section 39.13 is amended by adding the following new 
airworthiness directive:

Israel Aircraft Industries, LTD.: Docket 2000-NM-201-AD.

    Applicability: Model GALAXY airplanes having serial numbers 004 
through 012 inclusive, and serial number 015; certificated in any 
category.

    Note 1: This AD applies to each airplane identified in the 
preceding applicability provision, regardless of whether it has been 
modified, altered, or repaired in the area subject to the 
requirements of this AD. For airplanes that have been modified, 
altered, or repaired so that the performance of the requirements of 
this AD is affected, the owner/operator must request approval for an 
alternative method of compliance in accordance with paragraph (b) of 
this AD. The request should include an assessment of the effect of 
the modification, alteration, or repair on the unsafe condition 
addressed by this AD; and, if the unsafe condition has not been 
eliminated, the request should include specific proposed actions to 
address it.

    Compliance: Required as indicated, unless accomplished 
previously.
    To prevent fatigue failure of certain existing fasteners in the 
aft pickup fittings of the horizontal stabilizer, which could result 
in reduced structural integrity of the empennage, accomplish the 
following:

Fastener Replacement
