NPRM for Extex LTD, Pacific Supply Inc., Rolls Royce Corp., and Superior Air Parts Inc. Gas Producer Rotor Assembly Tie Bolts - 2005-NE-28-AD

Comment on [Docket No. FAA-2005-22594; Directorate Identifier 2005-NE-28-AD; Amendment 39-14659; AD 2006-13-06] RIN 2120-AA64 Table 1 of the subject AD lists part number A23008020 as a product of both Superior Air Parts and Extex. We have reviewed the PMA supplements issued to Extex and can find no part number A23008020 listed. In fact, we cannot locate any part manufactured by Extex prefixed with the letter A. The part number A23008020 appears to be assigned exclusively to a part manufactured by Superior Air Parts under their supplement 122.
