Applicability: Model AS 355 E, F, F1, F2, and N helicopters, equipped with dynamic components following overhaul (RG) or repair (RE) at the Eurocopter Helicopter Maintenance and Overhaul Facility (D.E.R.H.), listed in Tables 1 and 2 (as applicable) of paragraph 4 “Appendix” of Eurocopter Alert Service Bulletin No. 62.00.27.
Requirement: 1. Using the Equipment Log Cards (FMEs) of the dynamic components, check whether the dynamic components embody parts affected by this Directive, in accordance with the instructions specified in paragraph 2.B.1. of Alert Service Bulletin No. 62.00.27.
If the Requirement 1 check does not reveal the existence of a part affected by this Directive, no further action is required.
If the check reveals the existence of one or more part(s) affected, comply with the instructions specified in paragraph 2.B.2 of Alert Service Bulletin No. 62.00.27.
Comply with paragraph 2.B. of Alert Service Bulletin No. 62.00.27 on dynamic components that have been stored following repair or overhaul, before installation on aircraft.
Note: DGAC AD 2002-452(B) R1 refers.

AD/AS 355/69 Amdt 1 (continued)
Background: A discrepancy in the D.E.R.H. computer system, which is used to carry over the number of operating hours of the parts following repair or overhaul work, is the cause of incorrect completion of some Equipment Log Cards. The result of this discrepancy is that a part that has changed part number or serial number following repair or modification, may have been dispatched with incorrect operating hours. Affected items will show zero hours on their FME.
Amendment 1 is issued in response to a revision of the related DGAC AD, which introduces Alert Service Bulletins in place of the previously referenced Alert Telexes, with no change in technical content.
The original issue of this Airworthiness Directive became effective on 11 September 2002.
