CEF Industries new C-130/L100 Wing Flap Actuators, PN 8445M1 (inboard) and PN 8446M1 (outboard), are the result of extensive research, engineering, and testing. Market research at various C-130/L100 operators and overhaul facilities indicated a need to improve the service life of the ballscrew. The main contributor to short service life is the operating environment. Excessive wear between the ballnut and ballscrew is the primary cause for early removal. This result can generally be traced to a salt spray, sand, dust, and vibration environment. Heavy corrosion of the ballscrew shaft and torsion bar, as well as of flaking of chrome plating was noted on many short hour units. Given the aircraft design, protection of the flap actuator from the environment is not possible.
