The servos utilized in the Honeywell KFC 150/200/225/250/275/300/325/400 series have enclosures and baseplates that are no longer available from the OEM. When these require replacement, your only options are to: 1) buy a whole new servo unit or 2) upgrade the entire avionics package of the aircraft at a much higher price tag.
At Duncan Aviation’s avionics/instrument shop, we repair and overhaul an average of 100 KFC servos each month. Our repair capabilities are keeping these units available and at a significantly lower cost.
The overhaul includes a total breakdown of the servo to clean and inspect, replacing high-failure items that pose warranty issues. This keeps warranty and future maintenance costs to a minimum.
During the overhaul, we incorporate Service Memo 292 into the 8130 for your 13-month/1000-hour inspection on all Honeywell servos.
