Use of water is limited to takeoff operation up to an altitude of 10,000 feet (JT3D-1, -MC-6, -MC-7, -3) and 14,000 feet (JT3D-3B, -7) at the minimum ambient temperature as listed in the engine installation and operating manual. Takeoff using both water injection and dry takeoff power are limited to a maximum period of 5 minutes including operation with water injection for not more than 2½ minutes. With water injection the takeoff static thrust rating at sea level of 17,000 lb. (JT3D-1, JT3D-1-MC6, JT3D-1-MC7) and 18,000 lb. (JT3D-3) is extended to 90°F ambient temperature, 18,000 lb.

Power setting, power checks, and control of engine output in all operations is to be based upon P&WA engine charts referring to turbine discharge section gas pressures. Pressure probes are included in the engine assembly for this reason. NOTE 10. These engines meet FAA requirements for adequate turbine disk integrity and rotor blade containment and do not require external armoring. These engines have demonstrated satisfactory operation in icing conditions as defined in 4b.1(b) 7 and 8. NOTE 11. The serial number suffix "B" designates engines for the Boeing aircraft and the suffix "D" designates engines for the Douglas aircraft. Differences in these engines involve differences in the routing of external engine lines. NOTE 12.
