The latest Sikorsky All Operators Letter includes these paragraphs, which tend to support TM and II's comments:
It is the responsibility of the flight crew to continuously monitor all flight and navigation instruments to ensure that the aircraft is on its intended flight path and operating within the approved flight envelope at all times, with or without AFCS engaged. The flight crew has 100% control authority over the AFCS system at all times. All AFCS failure modes can be overridden by the pilot. At any time the pilot can deselect some or all of the autopilot features by depressing the panel switches (Coupled, Trim, SAS, etc.) and can manually fly the aircraft with full control authority. The aircraft is approved for VFR flight throughout the envelope with all autopilot, stability and trim functions selected off.
Investigation of S-76C serial no. 760780 September 2012 (Humberside Airport) incident identified that an electrical short had occurred in a wiring harness located in the cabin overhead area. Subsequent to this finding, the operating company issued a fleet-wide technical directive to inspect the wiring harness for signs of damage and to take corrective action where appropriate.
