QUALITY SERVICE

Picture
The Trinity Specialized Services' Team is committed to providing the highest quality product and superior customer service. We are here to serve you with any and all propeller service needs.  We offer a wide range of propeller services, from inspection and repair to full overhaul.  A propeller overhaul includes complete disassembly, nondestructive inspection, cad plating of steel parts, painting of blades, replacement of one time use hardware and o'rings, and performing static balance.  

Upon receiving a propeller it is disassembled, cleaned, Inspected, and sent through the process of the overhaul.  As set forth in the propeller overhaul manual, the reusable parts are inspected using various nondestructive testing methods.  The finish is stripped off of the parts by glass or plastic media blasting so that magnetic particle and liquid penetrant inspections can be performed.  The blades are measured for width, thickness, and length to determine their airworthiness, the paint is stripped off, track and face alignment is performed, and they are put through a wide array of nondestructive inspection, including eddy current and liquid penetrant.  Once the inspection process is completed, a new finish is then applied.  All of the reusable ferrous parts are cadmium plated, the aluminum parts go through an alodine, or anodize process.  Once the corrosion barriers are put back in place, the blades are painted, and the propeller is reassembled in accordance with the overhaul manual, which includes replacing the hardware, seals, and O'rings.  Once the blade angles have been set the propeller is then statically balanced and ready to be returned to the customer.  It is always a good idea to have a dynamic balance done after the overhauled propeller is installed on the airplane.  The dynamic balance ensures the propeller is functioning correctly at a working RPM.
