Every AD in the library whose text names the Pratt & Whitney PW4000, of which 149 are registered in the US.
17 not superseded, 5 of them with a repeat action. 27 listed in all, newest published October 3, 2012.
Listed by the model designations in each AD's text. An AD written for a part number, or for "all" engines of a maker, may name no model and so not appear here: search the library for the part or the maker as well.
