ADDRESSES: FOR FURTHER INFORMATION CONTACT: SUPPLEMENTARY INFORMATION: REGULATORY TEXT: 89-01-01 SOCIETE NATIONALE INDUSTRIELLE AEROSPATIALE (SNIAS): Amendment 39-6052. Applicability: All SNIAS Model AS 355E, AS 355F, and AS 355F1 helicopters (serial numbers before 5362) fitted with debris guards, Part Numbers (P/N) 355A58-0519-0201 and 355A58-0519-0391, certificated in any category, except those helicopters previously equipped with this identical modification. (Docket No. 87-ASW-62) Compliance: Required within the next 200 hours' time in service, unless already accomplished. To prevent engine failure (flameout) resulting from ingestion of atmospheric moisture in engine inlets, accomplish the following: (a) Install an engine automatic relight system in accordance with SNIAS Service Bulletin AS 355 No. 80.02, Revision 2, approved July 8, 1987 (SB No. 80.02 corresponds to SNIAS Modification AMS 350A07-1823, IFR-VFR versions; AMS 350A07-1856, IFR versions; AMS 350A07-1905, IFR-VFR versions; AMS 350A07-1910, IFR-VFR versions; AMS 350A07- 1920, IFR-VFR version). Installation of the SNIAS relighting kit requires exclusive utilization of Champion or Auburn igniter P/N 6877518 or Champion igniter P/N 23006266 and limits the service life of each newly installed igniter to 1,200 hours' time in service. Any of the required Champion or Auburn igniters already installed and having 1,000 or more hours' time in service must be replaced with new Champion or Auburn P/N 6877518 igniters or Champion P/N 23006266 igniters. NOTE: SNIAS Service Bulletin AS 355 No. 01.18, Revision 2, approved October 5, 1987, also pertains to this engine automatic relight system installation. (b) Incorporate into the applicable RFM the basic flight manual revisions and instrument flight rules (IFR) flight manual supplements (if IFR equipped), or later FAA-approved flight manual revisions, as follows: (1) For the Model AS 355E, basic rotorcraft flight manual, Revision 4, Code Date 87-10. (2) For the Model AS 355F, basic rotorcraft flight manual, Revision 3, Code Date 87-10 and IFR rotorcraft flight manual supplement 11.4, Revision 3, Code Date 87-12. (3) For the Model AS 355F1, basic rotorcraft flight manual, Revision 2, Code Date 87-10, and IFR rotorcraft flight manual supplement 11.4, Revision 1, Code Date 87- 12. (c) To insure that the limited service life of the igniters defined in paragraph (a) above is properly identified and adhered to, the following updates (or future revisions thereto) must be incorporated in the Master Servicing Recommendations-Chapter 5-99 (Airworthiness Limitations): (1) AS 355E, Revision 15, Page 21. (2) AS 355F, Revision 15, Page 23. (3) AS 355F1, Revision 15, Page 23. (d) Upon accomplishing the requirements of paragraphs (a), (b), and (c) above, the placard required by paragraph (a) of AD 86-24-02 may be removed. (e) Upon request, an alternate means of compliance which provides an equivalent level of safety with the requirements of this AD may be used when approved by the Manager, Rotorcraft Standards Staff, ASW-110, FAA, Fort Worth, Texas 76193-0110. (f) Continuous ignition systems previously found to be equivalent methods of compliance with priority letter AD 86-24-02, dated November 21, 1986; or with Amdt. 39-5796 (52 FR 46985; December 11, 1987) effective January 27, 1988, are approved as equivalent methods of compliance to this AD. The procedure shall be done in accordance with SNIAS Service Bulletin AS 355 No. 80.02, Revision 2, approved July 8, 1987. This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a)(1) and 1 CFR Part 51.
