1. APPLICABILITY:
Helicopters of following models:
- SA 360 C,
- SA 365 C, C1, C2 and C3,
- SA 330 F, G and J,
- AS 332 C, C1, L, L1 and L2,
- AS 365 N, N1, N2 and N3,
- AS 350 B, BA, B1, B2, B3, BB and D,
- A5 355 E, F, F1, F2 and N,

2. REASON:
This Airworthiness Directive is prompted by the discovery on several ferrry tanks of an electrostatic ground connector that was not electrically bonded to its support. During refuelling of a tank, the absence of this electrical bonding could in particular conditions generate an electric arc between the refuelling nozzle of the tanker and the fuel tank and could cause the fuel tank to explode.
3. MANDATORY ACTIONS AND COMPLIANCE TIME:
The following actions are rendered mandatory on the effective date of this Airworthiness Directive:
3.1. Before the next refuelling of the ferry fuel tanks listed in paragraph 1 above, which are already installed on aircraft, carry out the electrical bonding by complying once with the instructions given in paragraph C.C of the referenced Service Telexes.
3.2. Before installing spare ferry tanks listed in paragraph 1 above on aircraft, carry out the electrical bonding by complying once with the instructions given in paragraph C.C.2 of the referenced Service Telexes.
