original issue of this Directive but no later than 6 March 2006.

             For Requirement 2 - Concurrent with the Requirement 1 deactivation of the immersion detection function.
             For Requirements 3, 4 and 5 - Within three months after the effective date of this Amendment.
             This Amendment becomes effective on 15 February 2007.
Background:  The original issue of this Directive was issued following advice from the Direction Générale de l'Aviation Civile (DGAC) of France that some cases of untimely deployment of the emergency locator transmitter beacon on AS 332 L2 helicopters had been reported.  At that time further rulemaking by the DGAC to correct the unsafe condition was expected.

             The analysis carried out by the manufacturer has revealed an anomaly on the immersion sensor, which can give rise to untimely deployment of the emergency locator transmitter beacon.  Furthermore, some interface units may have been installed without a battery.  In addition to the loss of the emergency locator transmitter function, the dropping of the emergency locator transmitter beacon could be a danger to persons on the ground.
             The original issue of this Directive required the immersion sensor to be inhibited and a copy of the Directive to be inserted into the AFM.  This Amendment requires the replacement of the immersion sensor, the return to service of the sensor circuit and removal of the copy of the Directive from the AFM.
             The original issue of this Directive became effective on 6 February 2006.
