AMENDMENT:   39-10867

AD NUMBER:   98-23-03

SUBJECT HEADING:   Airworthiness Directives; Eurocopter France Model SA 330F, G, and J Helicopters

ACTION:   Final rule

SUMMARY:   This amendment adopts a new airworthiness directive (AD), applicable to Eurocopter France Model SA 330F, G, and J helicopters, that requires removing and replacing each tail rotor electrical bonding braid (bonding braid). This amendment is prompted by an in-service report of the failure of a bonding braid. The actions specified by this 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:   Effective December 10, 1998. The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of December 10, 1998.

ADDRESSES:   The service information referenced in this AD may be obtained from American Eurocopter Corporation,
2701 Forum Drive, Grand Prairie, Texas 75053-4005, telephone (972) 641-3460, fax (972) 641-3527. This information
may be examined at the FAA, Office of the Regional Counsel, Southwest Region, 2601 Meacham Blvd., Room 663,
Fort Worth, Texas; or at the Office of the Federal Register, 800 North Capitol Street, NW., suite 700, Washington, DC.

FOR FURTHER INFORMATION CONTACT:   Mr. Robert McCallister, Aerospace Engineer, FAA, Rotorcraft
Directorate, Rotorcraft Standards Staff, 2601 Meacham Blvd., Fort Worth, Texas 76137, telephone (817) 222-5121, fax
(817) 222-5961.

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 Eurocopter France Model SA 330F, G, and J helicopters, was published in the Federal Register on May 7, 1998 (63 FR 25180). That action proposed to require removal and replacement of each tail rotor electrical bonding braid.

Interested persons have been afforded an opportunity to participate in the making of this amendment. No comments were received on the proposal or the FAA's determination of the cost to the public. The FAA has determined that air safety and the public interest require the adoption of the rule as proposed, except for non-substantive editorial changes. Additionally, the part number as published in the Applicability section of the NPRM contained an extra "0". This has been corrected in this final rule. The FAA has determined that these changes will neither increase the economic burden on any operator nor increase the scope of the AD.

The FAA estimates that 2 helicopters of U.S. registry will be affected by this AD, that it will take approximately 2 work hours per helicopter to accomplish the required actions, and that the average labor rate is $60 per work hour. Required parts will cost approximately $250 per helicopter. Based on these figures, the total cost impact of the AD on U.S. operators is estimated to be $740.

The regulations adopted herein will 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 final rule does not have sufficient federalism implications to warrant the preparation of a Federalism Assessment.

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.

§ 39.13 [Amended]
2. Section 39.13 is amended by adding a new airworthiness directive (AD) to read as follows:

REGULATORY TEXT:  
98-23-03 EUROCOPTER FRANCE: Amendment 39-10867. Docket No. 97-SW-43-AD.
Applicability: Model SA 330F, G, and J helicopters, with tail rotor electrical bonding braids (bonding braids), part number (P/N) 332A031.1276.00, installed, certificated in any category, that have not been modified in accordance with AMS 332A07-66-003 or AMS 33207-66-072.

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 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.

(d) The replacement shall be done in accordance with Eurocopter France Service Bulletin SA 330 No. 65.73 R3, dated June 22, 1995. This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51. Copies may be obtained from American Eurocopter Corporation, 2701 Forum Drive, Grand Prairie, Texas 75053-4005, telephone (972) 641-3460, fax (972) 641-3527. Copies may be inspected at the FAA, Office of the Regional Counsel, Southwest Region, 2601 Meacham Blvd., Room 663, Fort Worth, Texas; or at the Office of the Federal Register, 800 North Capitol Street, NW., suite 700, Washington, DC.

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.

(e) This amendment becomes effective on December 10, 1998.
