MOBILE, Ala. - Teledyne Continental Motors is recalling and replacing an engine part in several hundred airplane engines after the part began to wear out more rapidly than normal. The Federal Aviation Administration grounded all the planes containing the hydraulic lifters until the parts are replaced. Rhett Ross, president of Teledyne Continental, said about 450 engines and parts sets were in question, and more than two-thirds have already been replaced. (Source: Mobile Press-Register, 11/25/09)
