Applicability: AS 332 L2 helicopters equipped with an optional type CPI 503 (Crash Position Indicator) emergency locator transmitter, fitted with an immersion sensor (water activated switch) part number (P/N) 50323. Requirement: 1. Check that the battery is installed in the interface unit and electrically inhibit the immersion detection function in compliance with the instructions specified in paragraph 2 of Eurocopter AS332 Alert Telex 25.01.71. 2.

The emergency locator transmitter beacon can still be released manually via the control unit and automatically in the event of a crash. Note 1: Although the immersion detection function is electrically inhibited, the emergency locator transmitter beacon can be set to transmit manually via its control unit. 3. Remove from service any immersion sensors (water-activated switches) P/N 50323, installed on aircraft or held as spares. 4. Replace immersion sensor (water-activated switch) P/N 50323 with an immersion sensor (water-activated switch) P/N 503232 and return the immersion detection function to an operative condition, in compliance with the instructions specified in paragraph 2 of the Eurocopter AS332 Alert Service Bulletin 25.01.71 dated 8 June 2006 or later EASA approved revision. 5.
