Applicability:

AS 332 helicopter, models and serial numbers (S/N) as listed in Table 1, equipped with a CPI 503 crash position indicator beacon.

Table 1

Helicopter Model

Serial Number

AS 332 L1
AS 332 L2

2050, 2111 and 2115
2608, 2610, 2612, 2614, 2616, 2622, 2632, 2634, 2636, 2639 and 2655

Requirement:

1. 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) 25.01.89 dated 16 April 2008 or later revision approved by the European Aviation Safety Agency (EASA).

2. 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.

Note: EASA AD 2008-0076 refers.

Compliance:

For Requirement 1 - Within the next 85 hours time in service or three calendar months, whichever occurs first after the effective date of this Directive.

For Requirement 2 - Concurrent with the Requirement 1 modification.

This Airworthiness Directive becomes effective on 5 June 2008.

Background:

The EASA has advised of incidents being reported of uncontrolled activation of the crash position indicator beacon due to the location of the water activated switch in the left hand sponson when exposed to splashing water.

\n```\n\n| | 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 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. The replacement of the switch was required for AS 332 L2 helicopters byAD/S-PUMA/64 Amdt 1 (EASA AD 2006-0300). |\n| --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |\n| | For these reasons, this Directive requires the relocation of the water-activated switch and, for a few AS 332 L1 helicopters, the replacement of the switch. |\n\n![](image.001.png) \nJames Coyne \nDelegate of the Civil Aviation Safety Authority\n\n23 April 2008","sortOrder":0},{"sectionNumber":"AD/S-PUMA/75","sectionType":"part","heading":"AD/S-PUMA/75","content":"## AD/S-PUMA/75","sortOrder":1},{"sectionNumber":"Crash Position Indicator Water Activated","sectionType":"part","heading":"Crash Position Indicator Water Activated Switch","content":"## Crash Position Indicator Water Activated Switch","sortOrder":2},{"sectionNumber":"6/2008","sectionType":"part","heading":"6/2008","content":"## 6/2008","sortOrder":3}],"analysis":{"flash_summary_failed":{"failed":true,"reason":"A positive credit balance is required for all requests, including BYOK, so fallback providers remain available.
