EASA AIRWORTHINESS DIRECTIVE 

AD No.: 2008-0076 

Date: 22 April 2008

No person may operate an aircraft to which an Airworthiness Directive applies, except in accordance with the 

requirements of that Airworthiness Directive unless otherwise agreed with the Authority of the State of Registry.

Type Approval Holder’s Name: 

EUROCOPTER 

Type/Model designation(s): 

EC225 LP and AS332 L1, L2 helicopters 

TCDS Number: EASA R.002 

Foreign AD: Not applicable 

Supersedure: None 

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 issued 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 flight of the beacon represents a risk of 

injury to persons on the ground. To prevent recurrence, Eurocopter has developed 

Modification (MOD) 332P083289.00 for AS 332 L2 and EC 225 LP version 

helicopters which consists in modifying the location of the water-activated switch; 

and MOD 332AMR3649.01 and MOD 332AMR3649.02 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 replacement 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 2008 
2/2 

Compliance: 

Required as indicated, unless accomplished previously: 

(1) Within the next 85 flight hours or three months, whichever occurs first after the 

effective date of this AD, relocate the water-activated switch and accomplish 

the associated modifications in accordance with the instructions of paragraph 

2.B of EUROCOPTER Alert Service Bulletin (ASB) No. 25A023 for the EC225 

and ASB No. 25.01.89 for AS332 L1 and L2 version 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.
