Airworthiness Directives; Israel Aircraft Industries, Ltd., Model 
1124 and 1124A, and Model 1125 Westwind Astra Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment adopts a new airworthiness directive (AD), 
applicable to all Israel Aircraft Industries, Ltd., Model 1124 and 
1124A, and certain Model 1125 Westwind Astra series airplanes, that 
requires a one-time inspection of the attachment bolts installed on the 
engine inlet cowl and aft nacelle attachment flanges to verify correct 
part numbers of the bolts, and replacement of any discrepant/incorrect 
bolt with a correct attachment bolt. The actions specified by this AD 
are intended to prevent failure of attachment bolts due to fatigue, 
which could result in separation of the engine inlet cowl and aft 
nacelle, and consequent damage to the horizontal or vertical 
stabilizer. This action is intended to address the identified unsafe 
condition.

DATES: Effective March 7, 2002.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of March 7, 2002.

ADDRESSES: The service information referenced in this AD may be 
obtained

from Galaxy Aerospace Corporation, One Galaxy Way, Fort Worth Alliance 
Airport, Fort Worth, Texas 76177. This information may be examined at 
the Federal Aviation Administration (FAA), Transport Airplane 
Directorate, Rules Docket, 1601 Lind Avenue, SW., Renton, Washington; 
or at the Office of the Federal Register, 800 North Capitol Street, 
NW., suite 700, Washington, DC.

FOR FURTHER INFORMATION CONTACT: Dan Rodina, Aerospace Engineer, 
International Branch, ANM-116, FAA, Transport Airplane Directorate,

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal 
Aviation Regulations (14 CFR part 39) to include an airworthiness 
directive (AD) that is applicable to all Israel Aircraft Industries, 
Ltd., Model 1124 and 1124A, and certain Model 1125 Westwind Astra 
series airplanes was published in the Federal Register on October 29, 
2001 (66 FR 54465). That action proposed to require a one-time 
inspection of the attachment bolts installed on the engine inlet cowl 
and aft nacelle attachment flanges to verify correct part numbers of 
the bolts, and replacement of any discrepant/incorrect bolt with a 
correct attachment bolt.

Comments

    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. No comments were submitted in response 
to the proposal or the FAA's determination of the cost to the public.

Conclusion

    The FAA has determined that air safety and the public interest 
require the adoption of the rule as proposed.

Cost Impact

    The FAA estimates that 299 airplanes of U.S. registry will be 
affected by this AD, that it will take approximately 1 work hour per 
airplane to accomplish the inspection, and that the average labor rate 
is $60 per work hour. Based on these figures, the cost impact of the AD 
on U.S. operators is estimated to be $17,940, or $60 per airplane.
    The cost impact figure discussed above is based on assumptions that 
no operator has yet accomplished any of the 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 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.
    For the reasons discussed above, I certify that this action (1) is 
not a ``significant regulatory action'' under Executive Order 12866; 
(2) is not a ``significant rule'' under 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. A final evaluation has been prepared for this action 
and it is contained in the Rules Docket. A copy of it may be obtained 
from the Rules Docket at the location provided under the caption 
ADDRESSES.

Adoption of the Amendment

    Accordingly, pursuant to the authority delegated to me by the 
Administrator, the Federal Aviation Administration amends 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:


2002-01-26  Israel Aircraft Industries, Ltd.: Amendment 39-12621. 
Docket 2001-NM-200-AD.

    Applicability: All Model 1124 and 1124A series airplanes, and 
Model 1125 Westwind Astra series airplanes having serial numbers 004 
through 072 inclusive and 074 through 078 inclusive; 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 failure of attachment bolts due to fatigue, which 
could result in separation of the engine inlet cowl and aft nacelle, 
and consequent damage to the horizontal or vertical stabilizer, 
accomplish the following:

Inspection and Replacement, if Necessary

    (a) Within 50 flight hours from the effective date of this AD, 
perform a one-time inspection of the bolts installed on the engine 
inlet cowl and aft nacelle attachment flanges to verify correct part 
numbers of the bolts. Before further flight, replace any discrepant 
bolts with the correct bolts, per 1124- Westwind (Israeli Aircraft 
Industries) Alert Service Bulletin 1124-54A-138, and Astra (Israeli 
Aircraft Industries) Alert Service Bulletin 1125-54A-247, both dated 
March 29, 2001; as applicable.

Alternative Methods of Compliance

    (b) An alternative method of compliance or adjustment of the 
compliance time that provides an acceptable level of safety may be 
used if approved by the Manager, International Branch, ANM-116, 
Transport Airplane Directorate, FAA. Operators shall submit their 
requests through an appropriate FAA Principal Maintenance Inspector, 
who may add comments and then send it to the Manager, International 
Branch, ANM-116.

    Note 2: Information concerning the existence of approved 
alternative methods of compliance with this AD, if any, may be 
obtained from the International Branch, ANM-116.

Special Flight Permits

    (c) Special flight permits may be issued in accordance with 
Secs. 21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 
21.197 and 21.199) to operate the airplane to a location where the 
requirements of this AD can be accomplished.

Incorporation by Reference

    (d) The actions shall be done in accordance with 1124-Westwind 
(Israeli Aircraft Industries) Alert Service Bulletin 1124-54A-138,
