AD 2011-16-05 Airworthiness Directives; Eurocopter France Model SA-365N and SA-365N1 Helicopters

Models named: SA-365N, SA-365N1. Read the applicability below — it usually turns on serial or part numbers too.

Eurocopter Model SA-365N and SA-365N1 helicopters, all serial numbers, except helicopters with a crossfeed between the fuel filler necks in which the two fuel tank high level fuel switches have been removed in accordance with modification kit 365A087690.00 or modification 0728B17; certificated in any category.

Within 10 hours time-in-service, or 30 days, whichever occurs first, unless accomplished previously. To prevent exposure of the electrical wires, which could lead to a short circuit and activation of the indicator light without the high fuel level actually being reached; and to prevent a short circuit, which could become an ignition source inside the fuel tank, and result in a fuel tank explosion and subsequent loss of control of the helicopter, accomplish the following: (a) Disconnect the fuel tank high level fuel switches in accordance with the Accomplishment Instructions, paragraph 2.B.1., and by referring to Figure 1 of Eurocopter Emergency Alert Service Bulletin No. 01.00.63, Revision 1, dated May 13, 2009 (EASB). (b) For helicopters without a crossfeed between the fuel filler necks, install a placard on or near the center console fuel panel in accordance with the Accomplishment Instructions, paragraph 2.B.2., and by referring to Figures 2 and 3 of the EASB. The placard must use the same unit of measurement as the fuel quantity indicator ( i.e., liters (l), kilograms (kg) or pounds (lb)), as depicted in Figure 2 of the EASB. (c) To request a different method of compliance or a different compliance time for this AD, follow the procedures in 14 CFR 39.19.
