Last weeks massive proposed airworthiness directive aimed at thousands of Engine Components International cylinder assemblies is drawing mixed reactions from engine overhaul shops, according to an AVweb canvass of shops this week. While some say the proposed AD is a kneejerk over reaction, at least one shop told AVweb that the AD is justified, based on the shops direct experience with cracking in ECi cylinders. Some shops have stopped recommending or using ECi cylinders because of perceived quality issues from ECis previous cylinder quality problems in 2009, while others report that customers are demurring on picking ECi cylinders for overhauls and favoring factory or Superior Air Parts cylinders instead.
