|
WHAT DOES A SUCCESSFUL AVIONICS CLEANING AND CORROSION PREVENTION AND CONTROL PROGRAM DEPEND UPON?
|
A SUCCESSFUL PREVENTIVE MAINTENANCE PROGRAM.
|
|
|
WHAT DO PREVENTIVE MAINTENANCE PROGRAMS AT ORGANIZATIONAL, AND INTERMEDIATE-LEVEL MAINTENANCE ACTIVITIES ACCOMPLISH?
|
REDUCE THE MAINTENANCE TIME SPENT REPAIRING CORROSION DAMAGE;REDUCE THE MAINTENANCE ACTIONS CAUSED BY CORROSION;INCREASE AVIONICS SYSTEM RELIABILITY, SENSITIVITY,AND OUTPUT POWER; AND REDUCE THE PHANTOM GRIPES CAUSED BY DIRT, CORROSION,AND MOISTURE IN CONNECTORS, PLUGS, AND RECEPTACLES.
