Date: 9/28/07 0200 CDT

Program: Angel One
	Arkansas Children's Hospital
	800 Marshall St.
	Little Rock, AR 72202

Type: S-76 C 
Tail #: N760AF
Operator/Vendor: Own Part 135

Weather: Clear. Not a factor

Team: Pilot, Flight Nurse, Flight Respiratory Therapist. No injuries reported. Patient on board. 

Description: 
	At 0200, aircraft N760AF (Sikorsky S-76 C+) was transporting a patient
	from Baxter Regional Medical Center back to Arkansas Children's
	Hospital.  While departing the hospital helipad with a patient on
	board, the aircraft experienced a power fluctuation and an unusual
	vibration.  The crew took immediate action and landed the aircraft at
	the Baxter Regional airport.  No injuries or damage were sustained to
	the crew or aircraft.  N761AF was dispatched to transport the crew and
	patient back to ACH without further incident. 
	Further investigation by maintenance staff in conjunction with
	Sikorsky engineering revealed a problem with the collective position
	indicator for the number 1 engine.  While the faulty collective
	position indicator was running sluggish and caused the low side RPM
	problem, it was not giving enough of a Delta factor to cause a
	computer failure light.  The collective position indicator was
	replaced, engines inspected and aircraft returned to service October
	1, 2007.
