AVSpare engines are identified with serial numbers, with performance specification numbers, and with arrangement numbers. In some of the cases, modification numbers are used. These numbers are shown on the Serial Number Plate and the Information Plate that are mounted on the engine.
AVSpare dealers need these numbers in order to determine the components that were included with the engine. This permits accurate identification of replacement part numbers.
