Pratt & Whitney JT8D Bleed Air Valve, C13 stage. P/N 502042 or 1078A789643. It is used in average condition removed from a high time engine but I have no paperwork for it so it is sold as a nonairworthy item only.
The Pratt & Whitney JT8D was extensivelly used by civilian aircraft around the world such as the Boeing 727, Boeing 737, the DC-9 and MD-80 and it is still used today under the J52 (JT8D-219) turbojet designation primarily by the military on aircraft such as the KC-135 Stratotanker, etc. It would make an excellent show and conversation piece for the office or home. Sold as is, no returns.
