### ATA 25 Equipment & Furnishings – CPI (Crash Position Indicator) ELT Water-activated Switch – Relocation

Manufacturer(s): EUROCOPTER (Formerly EUROCOPTER FRANCE)

Applicability: - EC 225 LP helicopters, serial numbers (s/n) 2603, 2615, 2648, 2650, 2651, 2653, 2654, 2658, 2660 and 2662, - AS 332 L1 helicopters, s/n 2050, 2111 and 2115, and - AS 332 L2 helicopters, s/n 2608, 2610, 2612, 2614, 2616, 2622, 2632, 2634, 2636, 2639 and 2655 that are equipped with a CPI 503 crash position indicator beacon.

Reason: This Airworthiness Directive (AD) is is sued following the discovery of uncontrolled activation of the crash position indicator beacon due to the location of the wateractivated switch in the LH sponson which was highly exposed to splashing water. Inadvertent and uncontrolled deployment in f light of the beacon represents a risk of injury to persons on the ground. To prev ent recurrence, Eurocopter has developed Modification (MOD) 332P083289.00 for AS 332 L2 and EC 225 LP version helicopters which consists in modifying t he location of the water-activated switch; and MOD 332AMR3649.01 and MOD 332A MR3649.02 for AS 332 L1 helicopters which consist in modifying the location of the water-activated switch and replacing the Part Number (P/N) 50323 water-activated switch with a P/N 503232 unit. For AS 332 L2 and EC 225 LP helicopters, the repl acement of the switch was required by EASA AD 2006-0300. For the reasons described above, this EASA AD requires the relocation of the water-activated switch and, for a few AS 332 L1 helicopters, the replacement of the switch.

Effective Date: 06 May 20082/2 Compliance: Required as indicated, unless accomplished previously: (1) Within the next 85 flight hours or thr ee months, whichever occurs first after the effective date of this AD, relocate t he water-activated switch and accomplish the associated modifications in accordan ce with the instructions of paragraph 2.B of EUROCOPTER Alert Service Bu lletin (ASB) No. 25A023 for the EC225 and ASB No. 25.01.89 for AS332 L1 and L2 ve rsion helicopters, referenced below; (2) Concurrent with the modification as required by paragraph (1) of this AD, for AS 332 L1 helicopters s/n 2050, 2111 and 2115, replace the P/N 50323 water-activated switch with a P/N 503232 unit.
