What is the first step in making sure an aircraft is safe for maintenance?
Installing safety pins in all stations
Making sure fire fighting equipment is available
Making sure aircraft is positioned chocked and grounded
Checking the aircraft forms for the aircraft status
What hazard is of special concern during aircraft brake fires?
Excessive smoke from burning tires
Flying debris resulting from tire blowouts
Flying debris resulting from strut collapse
Intense light from burning brake components that can harm vision of looked at
Bombs can be expected to detonate within how long after being enveloped in flames?
Instantaneously
45 seconds to one minute
Two to four minutes
Five to ten minutes
When missiles are involved in an aircraft fire, approach the fire, if possible, from
The side of the aircraft
The rear of the aircraft
The front of the aircraft
Whichever way best facilitates fire fighting efforts
Hailstones are classified as what type of foreign object damage (FOD)?
Stones
Pebbles
Gravel
Miscellaneous
What is the FOD walk?
Any walkway for storing debris temporarily
An inventory of tools before and after each job
An organized inspection and physical pickup of foreign objects
A place to store personal effects while working on the flight line
Anytime you see magnesium, it will always be
Primed and top coated due to its low resistance to corrosion
Heavily lubricated due primarily to its low resistance to corrosion
Free from lubricants due to its high resistance to corrosion
Bare due to primarily due to its high resistance to corrosion
Aluminum's formation of a tightly adhering oxide film
Prevents it from being primed and top coated
Offers reduced resistance under all corrosive conditions
Provides increased resistance under mild corrosive conditions
Requires heavy lubrication to prevent further degradation of structural integrity
In unprotected, ferrous metal surfaces are
Highly resistant to corrosion
Easily corroded if moisture is absent
Easily corroded if moisture is present
Easily corroded in the presence of high-temperature exhaust
How does corrosion appear on nickel or chrome plated steel surfaces?
Small spots on the plated surface
A dull-gray product that can be wiped off
A bluish green coating on the surface of the product
A white yellow corrosion product appears on the exposed surfaces
The main cause of the corrosion of spot welded metals is the
Excessive use of lubricant attacking the structure
Dissimilar metal contact from the binding agents used
Entrance and entrapment of corrosive agents between the layers of metals
heat damage to the anti-corrosion coating caused by the welding process
Piano hinges are prime spots for corrosion because they are natural traps for dirt, salt, and moisture, and
Dissimilar metal contact between the steel pin and the aluminum hinge tangs
Residual oil quite often masks small quantities of water that set up hidden corrosion cells
Their constant actuation by maintenance personnel results in excessive wear of their finishes
Their protective finish is very often blistered by heat, blasted away by the high-velocity gases, and abraded by spent shell casings and solid particles from gun and rocket exhausts
What corrosion accelerant agent does dust, dirt, acid spills, or waste materials provide?
Anode
Cathode
Exfoliate
Electrolyte
When approaching an aircraft with hot brakes, approach the tire area from
The side of the tire
The upwind side of the tire
The front of back of the tire
Whichever way best facilitates fire-fighting efforts
