Aeronautical Accessories has received for the Bell 407 an STC that increases available useful load by 400 pounds or in-ground-effect hover by 3,000 feet. The STC draws on excess power available from the 407’s Rolls-Royce 250-C47B to support revisions of the 407’s performance charts for in-ground-effect and out-of-ground-effect hover. Specifically, it uses available power for up to 10 percent above minimum-specification engines for outside air temperatures up to 51.7 degrees C (125 degrees F). The performance boost requires no hardware or software changes to the aircraft or its engine. It also results in no change to time between overhaul or warranty costs because no engine limits are changed.
