throughout the grain of the steel? - ANS-Across the grain.
How are rubber deicer boots attached to the main edges of plane wings and tail surfaces? -
ANS-They are bonded to the surface with an adhesive. Boots at the older aircraft were
connected with machine screws and Rivnuts.
How are the vanes of a moist-kind air pump lubricated? - ANS-With engine oil directed into
the pump through a small hole in the base of the pump.
How are the wrinkles pull out of cotton fabric? - ANS-Wet the cotton with water and permit it
to dry.
How can a vinyl movie sticker be removed from an aluminum alloy floor? - ANS-Place a
material saturated with cyclohexanone or MEK over the sticker till it's miles softened, and
scrape it off of the floor with a plastic scraper.
How can an exhaust device be checked for leaks? - ANS-Pressurize it with the release from
a vacuum cleaner and wipe the out of doors of the system with a cleaning soap answer. Any
leak will cause bubbles to shape.
How can water entrapped in a honeycomb shape be detected? - ANS-By the use of
radiographic inspection.
How are you able to make certain of getting an O-ring made of the perfect cloth for a
particular hydraulic issue? - ANS-The O-ring must have the suitable part range and it should
have been obtained from a reputable source.
How can you be sure that a replacement seal in a hydraulic thing is well suited with the fluid
used inside the machine? - ANS-Use only the seal recognized through part quantity this is
designated in the component maintenance guide.
How can you stumble on jet fuel within the sample taken from the tank sump drains? -
ANS-Jet gas is essentially clear and it has an odor just like kerosine.
,How are you able to decide the proper coaxial cable and connectors to use in an aircraft
radio set up? - ANS-Refer to the radio set up instructions for the proper part variety for the
cable and connectors.
How are you able to determine the kingdom of charge of a CO₂ fireplace extinguisher? -
ANS-By its weight.
How are you able to decide the country of price of a freon fire extinguisher container? -
ANS-By the pressure shown on the built-in gage.
How can you decide whether or not or not a built-in fireplace extinguishing device has been
discharged? - ANS-By checking the blowout plugs at the out of doors of the aircraft near the
extinguisher agent bottles.
How can when an ELT battery have to get replaced or recharged? - ANS-By the date
marked on the out of doors of the transmitter.
How are you able to inform that there is carbon monoxide inside the aircraft cabin? -
ANS-Indicator crystals in a CO detector will change color, from a typically bright colour to a
dark coloration. At lethal levels of CO they may turn black.
How are you able to inform, on a preflight inspection, that the pitot heater is operating? -
ANS-Turn it on for approximately a minute after which on the stroll-round inspection, sense it
to peer that it's miles heat.
How do you stumble on decay in a wood structure? - ANS-Stick a pointy-pointed knife blade
within the suspect region and pry the wooden up. If the wood is good, it will come up as an
extended splinter; if it's far decayed it's going to arise as a chunk.
How do you grind the factor of a twist drill this is to be used for drilling transparent acrylic
cloth? - ANS-The slicing part must be dubbed off to a 0 rake perspective, and the blanketed
perspective of the top have to be floor to one hundred forty levels.
How do you degree the amount of brake lining wear on single disk brakes? - ANS-Measure
the clearance between the disk and the inboard side of the brake housing with the brakes
implemented.
How does a shimmy damper hold a nose wheel from shimmying? - ANS-It acts as a small
hydraulic shock absorber between the piston and the cylinder of the nostril-wheel surprise
strut.

actuate.
How is a gas leak indicated on a reciprocating-engine-powered aircraft? - ANS-The dye
within the gasoline stains the area across the leak.
How is a scarf splice on a wing spar strengthened? - ANS-Solid spruce or birch plywood
reinforcing plates are glued to each aspect of the spar, focused at each end of the scarf.

If the gadget is non-stop and now not shorted, the fire-warning light and bell will actuate.
How is a vapor-cycle cooling system checked for refrigerant leaks? - ANS-Hold the probe of
an electronic leak detector under any suspect fitting or aspect. If there's a leak, the tone of
the sound produced via the detector will change.
How is a twine package protected from chafing wherein the bundle is going via a hole in a
fuselage body or bulkhead? - ANS-The edges of the hollow are covered with a bendy
grommet, and the bundle is secured to the structure with a cushioned clamp.
How is aircraft plywood organized for making a compound bend? - ANS-Soak the timber in

and pay attention on 121.5 or 243.0 MHz. Make the take a look at for the duration of the first
5 minutes of the hour and do no longer allow the ELT to operate for greater than three
sweeps. If the ELT is operated outside of this time frame, you must contact the manipulate
tower earlier than undertaking the check.
