[Docket No. 97-SW-43-AD]


Airworthiness Directives; Eurocopter France SA 330F, G, and J 
Helicopters

AGENCY: Federal Aviation Administration, DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: This document proposes the adoption of a new airworthiness 
directive (AD) that is applicable to Eurocopter France Model SA 330F, 
G, and J helicopters. This proposal would require removal and 
replacement of each tail rotor electrical bonding braid (bonding 
braid). This proposal is prompted by one in-service report of

[[Page 25181]]

failure of a bonding braid. The actions specified by the proposed AD 
are intended to prevent failure of a bonding braid due to fatigue, 
resulting impact with the tail rotor blades, and subsequent loss of 
control of the helicopter.

DATES: Comments must be received on or before June 8, 1998.

ADDRESSES: Submit comments in triplicate to the Federal Aviation 
Administration (FAA), Office of the Regional Counsel, Southwest Region, 
Attention: Rules Docket No. 97-SW-43-AD, 2601 Meacham Blvd., Room 663,

Discussion

    The Direction Generale De L'Aviation Civile (DGAC), which is the 
airworthiness authority for France, recently notified the FAA that an 
unsafe condition may exist on Eurocopter France Model SA 330F, G, and J 
helicopters. The DGAC advises that, in order to improve the in-service 
resistance of the bonding braids and to limit the risks of their 
impacting the blades, the bonding braids and their attachment clamps 
were to be removed and replaced before September 1, 1995.
    Eurocopter France has issued Eurocopter France Service Bulletin SA 
330 No. 65.73 R3, dated June 22, 1995. The DGAC classified this service 
bulletin as mandatory and issued AD 95-153-072(B), dated July 19, 1995, 
in order to assure the continued airworthiness of these helicopters in 
France.
    This helicopter model is manufactured in France 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 tot his 
bilateral airworthiness agreement, the DGAC has kept the FAA informed 
of the situation described above. The FAA has examined the findings of 
the DGAC, 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.
    Since an unsafe condition has been identified that is likely to 
exist or develop on other Eurocopter France Model SA 330F, G, and J 
helicopters of the same type design registered in the United States, 
the proposed AD would require replacing the bonding braids. The actions 
would be required to be accomplished in accordance with the service 
bulletin described previously.
    The FAA estimates that 2 helicopters of U.S. registry would be 
affected by this proposed AD, that it would take approximately 2 work 
hours per helicopter to accomplish the proposed actions, and that the 
average labor rate is $60 per work hour. Required parts would cost 
approximately $250 per helicopter. Based on these figures, the total 
cost impact of the proposed AD on U.S. operators is estimated to be 
$740.
    The regulations proposed herein would not have substantial direct 
effects 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, in 
accordance with Executive Order 12612, it is determined that this 
proposal would not have sufficient federalism implications to warrant 
the preparation of a Federalism Assessment.
    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 a new airworthiness directive 
to read as follows:

Eurocopter France: Docket No. 97-SW-43-AD.

    Applicability: Model SA330F, G, and J helicopters with tail 
rotor electrical bonding

[[Page 25182]]

braids, part number (P/N) 332A031.1276.00, that have not been 
modified in accordance with AMS 332A07-66-003 or AMS 33207-66-072, 
installed, certificated in any category.

    Note 1: This AD applies to each helicopter 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 helicopters that have been modified, 
altered, or repaired so that the performance of the requirements of 
this AD is affected, the owner/operator must use the authority 
provided in paragraph (b) to request approval from the FAA. This 
approval may address either no action, if the current configuration 
eliminates the unsafe condition, or different actions necessary to 
address the unsafe condition described in this AD. Such a request 
should include an assessment of the effect of the changed 
configuration on the unsafe condition addressed by this AD. In no 
case does the presence of any modification, alteration, or repair 
remove any helicopter from the applicability of this AD.

    Compliance: Required within the next 60 calendar days, unless 
accomplished previously.
    To prevent failure of a tail rotor electrical bonding braid 
(bonding braid) due to fatigue, resulting impact with the tail rotor 
blades, and subsequent loss of control of the helicopter, accomplish 
the following:
    (a) Remove the bonding braids, P/N 332A31.1276.00, and replace 
them with airworthy bonding braids, P/N 332A31.1276.01 in accordance 
with paragraphs B and C of the Operating Procedure of Eurocopter 
France Service Bulletin SA 330 No. 65.73 R3, dated June 22, 1995.
    (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, Rotorcraft Standards Staff, 
Rotorcraft Directorate, FAA. Operators shall submit their requests 
through an FAA principal Maintenance Inspector, who may concur or 
comment and then send it to the Manager, Rotorcraft Standards Staff.

    Note 2: Information concerning the existence of approved 
alternative methods of compliance with this AD, if any, may be 
obtained from the Rotorcraft Standards Staff.

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

    Note 3: The subject of this AD is addressed in Direction 
Generale L'Aviation Civile (France) AD 95-153-072(B), dated July 19, 
1995.

    Issued in Fort Worth, Texas, on April 29, 1998.

Acting Manager, Rotorcraft Directorate, Aircraft Certification Service.
