Requires amending the rotorcraft flight manual’s emergency procedures.  The AD stems from misleading information identified in the AW189 RFM Emergency procedure associated with the “1(2) FUEL LOW” caution message. In particular, the current procedure instructs the pilot to land as soon as practicable within 20 minutes. However, this remaining flight time is guaranteed only if a constant torque value of 50 percent is maintained. The correct time limit depends on the fuel consumption of the different engine ratings. This condition, if not corrected, could lead to the wrong estimation of the remaining flight time in low fuel condition, possibly resulting in an uncommanded engine in-flight shut-down and forced landing, with consequent damage to the helicopter and/or injury to occupants.
