Failed Points Assembly

摘要

The engine, installed in a Lancair Ⅳ-P Experimental, began to run poorly. On inspection, the left magneto was found inoperative. The magneto was removed, disassembled and inspected. The follower arm had separated and was laying in the top of the magneto. The right magneto was removed for inspection, and corrosion was seen on the follower arm in the area where the stiffener section stops.
