EASA AD 2019-0110

 
Requires repetitive checks of torque conformation boxes and replacement, if necessary. This AD stems from cracks found on the soldered joints of certain torque conformation boxes. Although no events in operation were reported of One Engine Inoperative (OEI) ratings maximum power unavailability, the failure mode analysis for these boxes demonstrated that such an event could not be excluded. This condition, if not detected and corrected, could lead to engine in-flight shut-down, possibly resulting in reduced control of the helicopter.
