HC-144 COMPONENT REPAIRS AND OVERHAULS

STATEMENT OF WORK

1.0 BACKGROUND

1.1 The United States Coast Guard (USCG) currently operates eighteen (18) HC-144 Maritime Patrol Aircraft each powered by two CT7-9C3 turboprop engines. The aircraft is manufactured by AIRBUS in Seville, Spain. These aircraft are procured under the authority of the Aviation Program Management Office. While the base CASA CN-235-300M aircraft provides the foundation for the HC-144, changes in the base aircraft configuration and the addition of supplementary systems have been combined resulting in a CG01 version of the CN-235-300M.

1.2 These Maritime Patrol Aircraft are operated differently from general aviation in support of search and rescue missions, as well as surveillance and reconnaissance missions. USCG HC-144 missions require frequent operation at lower altitudes and in salt-laden environments. These environments accelerate corrosion on airframe structures, engines, and components of the aircraft. The aircraft and its components are inspected by USCG personnel In Accordance With (IAW) the Original Equipment Manufacturers' (OEM) periodic requirements and in conjunction with the USCG's specialized Asset Computerized Maintenance System (ACMS).

1.3 There are additional requirements for the CG01 version listed in the Corrosion Control Plan Manual, NT-3-DCO-03162 for “Marinization” as outlined in Drawing 35-94453-00.
