WHAT IS THE GREATEST THREAT TO THE SOUNDNESS OF METALS & TO THE STRUCTURAL INTEGRITY OF AN A/C?
METAL CORROSION.
WHAT IS THE PRIMARY CONSIDERATION OF A MANUFACTURER DURING THE DESIGN AND PRODUCTION OF AN A/C?
AERODYNAMIC EFFICIENCY.
WHAT IS THE METAL CORROSION?
THE DECAY OF METALS AS THE COMBINE WITH OXYGEN TO FORM METALLIC OXIDES.
WHAT IS CORROSION?
A CHEMICAL PROCESS THAT IS THE REVERSE OF THE PROCESS OF SMELTING THE METALS FROM THEIR ORES.
WHAT DOES CONTROL OF CORROSION DEPEND UPON?
MAINTAINING A SEPARATION BETWEEN SUSCEPTIBLE ALLOYS AND THE CORROSIVE ENVIRONMENT.
HOW DOES THE CONTROL OF CORROSION BEGIN?
WITH AN UNDERSTANDING OF THE CAUSES AND THE NATURE OF CORROSION.
WHAT MAY THE ELECTRICAL CONDUCTOR BE IN ELECTROCHEMICAL CORROSION?
ANY FOREIGN MATERIAL, SUCH AS WATER, DIRT, GREASE, OR ANY DEBRIS THAT IS CAPABLE OF ACTING AS AN ELECTROTYTE.
THE PRESENCE OF WHAT IN ANY FOREGOING MEDIUM ACCELERATES THE CURRENT FLOW AND INCREASES THE RATE OF CORROSIVE ATTACK?
SALT.
WHAT IS THE LARGEST SINGLE CAUSE OF A/C CORROSION?
THE SALT IN SEAWATER AND THE SALT IN THE AIR.
WHAT DETERMINES THE RATE OF THE CORROSION PROCESS?
THE TEMPERATURE,HUMIDITY, AND CHEMICALS IN THE ENVIRONMENT.
WHAT IS THE SINGLE LARGEST CONTRIBUTOR IN AVIONICS CORROSION?
MOISTURE.
WHAT IS USED TO SCHEDULE AND RECORD ALL CORROSION MAINT. ACTIONS?
THE SE CUSTODY & MAINTENANCE HISTORY RECORD, OPNAV 4790/51
HOW OFTEN MUST A/C BE WASHED AND CLEANED?
AT LEAST TWICE A MONTH, UNLESS OTHERWISE DIRECTED BY NAVAIR.
WHAT CONDITIONS EXIST THAT SHOWS CLEANING OF THE A/C IS NEEDED?
AN APPRECIABLE AMOUNT OF SOIL ACCUMULATED WITHIN EXHAUST TRACK AREAS;THE PRESENCE OF SALT DEPOSITS OR OTHER CONTAMINANTS, SUCH AS STACK GASES, EVIDENCE OF PAINT SURFACE DECAY, SUCH AS SOFTENING, FLAKING, OR PEELING; AND THE PRESENCE OF EXCESSIVE OIL OR EXHAUST DEPOSITS, SPILLED ELECTROLYTE, AND DEPOSITS AROUND BATTERY AREAS.
WHAT EVENTS OCCUR THAT MAKES CLEANING THE AIRCRAFT ALWAYS MANDATORY?
IMMEDIATELY AFTER EXPOSURE TO FIRE-EXTINGUISHING MATERIALS; EXPOSURE TO ADVERSE WEATHER CONDITIONS AND SALT SPRAY, THE A/C HAS BEEN PARKED NEAR SEAWALLS DURING HIGH WIND CONDITIONS; LOW-LEVEL FLIGHT;AND REPAIRS OR SERVICE THAT HAS LEFT STAINS, SMUDGES,OR OTHER GROSS EVIDENCE OF MAINTENANCE
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.
WHERE ARE THE MATERIALS LISTED THAT YOU SHOULD USE WHEN CLEANING OR PERFORMING CORROSION CONTROL ON A/C AND NON AVIONICS A/C COMPONENTS?
IN A/C CLEANING AND CORROSION CONTROL FOR O AND I MAINTENANCE LEVELS, 01-1A-509.
WHAT IS HAZARDOUS MATERIAL?
ANY MATERIAL PRESENTING HAZARDS TO PERSONNEL,PROPERTY,OR THE ENVIRONMENT BY HANDLING, STORING,AND USING SUCH MATERIALS.
WHAT SHOULD BE DONE BEFORE OPENING A CONTAINER OF SOLVENT THAT HAS BEEN STORED IN A HIGH-TEMPERATURE AREA?
YOU SHOULD COOL IT DOWN, BY USING A STREAM OF WATER.
WHAT SHOULD YOU DO BEFORE STORING A CONTAINER?
INSPECT THEM FOR LEAKS AND ENSURE COMPLETE CLOSURE OF ALL PLUGS,CAPS,AND COVERS.
