Superior Extends Cylinder Warranty
Superior Air Parts's new warranty lasts for 37 months, and is retroactive to cylinders bought after Jan. 1, 2018.

Superior Air Parts, the manufacturer of FAA-approved PMA piston engine parts, has increased the warranty period for its new Millennium cylinders to 37 months or time between overhaul (TBO), whichever comes first. The company also will warranty new piece parts for up to 24 months or TBO. Its warranty covers manufacturing defects and applies retroactively to cylinders and parts sold after Jan. 1, 2018.

Superior now manufactures most complex parts and components in-house on sophisticated new machine tools installed at its headquarters in Coppell, Texas. This includes making its own cylinders and, more recently, adding manufacture of Continental 550-series pistons.
