Every AD in the library whose text names the Sikorsky S-64F, of which 5 are registered in the US.
2 not superseded, 1 of them with a repeat action. 3 listed in all, newest published November 22, 2013.
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.
