Airworthiness Directive · Amendment 39-11692 · Eurocopter France Model SA-366G1 Helicopters
Eurocopter France Model SA-366G1 Helicopters
Model SA-366G1 helicopters, certificated in any category.
Note 1: This AD applies to each helicopter identified in the preceding applicability provision, regardless of whether it has been otherwise modified, altered, or repaired in the area subject to the requirements of this AD. For helicopters that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (b) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.
This amendment adopts a new airworthiness directive (AD), applicable to Eurocopter France Model SA-366G1 helicopters, that requires replacing certain electrical modules with airworthy electrical modules. This amendment is prompted by the discovery of several defective electrical modules. The actions specified by this AD are intended to prevent loss of electrical continuity, which could cause loss of critical systems and subsequent loss of control of the helicopter.
To prevent loss of electrical continuity, which could cause loss of required systems and subsequent loss of control of the helicopter, accomplish the following:
(a) Replace each “CONNECTRAL” green electrical module that does not have a white dot on the face and that has a manufacturing code of 95/16 through 96/21 with an airworthy electrical module. Those manufacturing codes identify modules manufactured between the beginning of the 16th week of 1995 and the end of the 21st week of 1996.
