Teledyne Continental Motors (TCM) is to inspect up to 3,000 engines for possible metallurgical flaws in crankshafts manufactured between April 1998 and March 2000. The problem surfaced last month and prompted the FAA to issue an emergency airworthiness directive. TCM may have to meet $12 million in inspection and replacement crankshafts costs. It has begun legal action against a number of its suppliers.
