NOTE 18: REMOVED NOTE 19. Pratt & Whitney document number FR-22024 (latest revision), titled "Configuration Management Accounting Report", is a cross reference list of commercial (PW2000 engine series) service bulletins and their military equivalent (F117 engine model). This document is updated monthly. NOTE 20. Ground operation in icing condition requires adherence to procedures stated in Aircraft Flight Manual (AFM) for all engine models. These procedures include periodic speed run ups and/or inspections and de-icing procedures (reference applicable AFM for details). NOTE 21. NOTE 22. The 5 minute takeoff time limit may be extended to 10 minutes for one engine(s) inoperative or shutdown.
