Airworthiness Directives; Eurocopter France Model SA-365N and SA-365N1 Helicopters
type: Action
additional type: https://schema.org/LegalForceStatus
description: This amendment adopts a new airworthiness directive (AD) for the specified Eurocopter France (Eurocopter) model helicopters. This action requires you to disconnect the high level fuel switches in the fuel tanks on the affected helicopters. In addition, for helicopters without a crossfeed between the fuel filler necks, you must install a placard on or near the center console fuel panel that specifies fuel transfer limitations. This amendment is prompted by a report that a high level fuel switch probe unit installed on a Model SA-365N helicopter in the rear (right-hand) auxiliary fuel tank group separated, causing damage to the insulation of the electrical wires which supply electrical power to the high level indicator light on the fuel control panel during a fuel transfer. This condition, if not corrected, could lead to 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. Additionally, a short circuit could become an ignition source inside the fuel tank, and result in a fuel tank explosion and subsequent loss of control of the helicopter.
