Question 1

The nondestructive inspection method most often used for parts
made of iron or iron alloys is magnetic particle inspection. Magnetic
particle inspection is useful for detecting cracks, splits, seams, and
voids that form when a metal ruptures.

Answer 1

Magnetic Particle Inspection

Question 2

-Once an engine part is clean, it must be inspected closely for
damage. The first type of inspection that is usually done is a thorough
visual inspection aided by a magnifying glass, flashlight, and, if
necessary, a borescope. Visual inspections are done to detect many
different visible surface defects in parts.

Answer 2

Visual Inspection

Question 3

Starts with our technicians applying a special liquid to the inspection
surface, which a process called capillary action then draws into any
surface breaking discontinuities.

Answer 3

Liquid Penetrant Inspection

Question 4

Combines electricity and magnetism to create a magnetic field on the
conductive metal surface

Answer 4

Eddy Current Inspection

Question 5

Methods use sound waves to find defects and measure thickness.

Answer 5

Ultrasonic Inspection

Question 6

A non-destructive testing (NDT) method which uses either x-rays or
gamma rays to examine the internal structure of manufactured
components identifying any flaws or defects.

Answer 6

Radiography

Question 7

A partial separation of material
usually caused by vibration,
overloading, internal stresses,
defective assembly, or fatigue.

Answer 7

CRACKS

Question 8

The presence of small voids,
bubbles, or air pockets within a
material. These voids can occur
during the manufacturing process,
especially in composite materials
like carbon fiber reinforced
polymers (CFRP) or fiberglass,
which are widely used in modern
aircraft construction.

Answer 8

POROSITY

Question 9

These are overlapping layers of material,
often metal, where one part of a sheet
is folded or overlapped onto another. In
aircraft structures, are common in
areas like the skin of the fuselage or
wing

Answer 9

LAPS

Question 10

These are the joints where two edges of
materials meet or are fastened together, often
with rivets, welds, or adhesives.

Answer 10

SEAMS

Question 11

-Aircraft can have various plastic components,
including interior panels, fairings, or nonstructural parts made from materials like acrylic,
polycarbonate, or composite plastics.

Answer 11

PLASTICS

Question 12

Aircraft can have various plastic components,
including interior panels, fairings, or nonstructural parts made from materials like acrylic,
polycarbonate, or composite plastics.

Answer 12

PLASTICS

Question 13

materials in aircraft can be found
in high-temperature applications, such as
thermal barriers in engines or insulating
components

Answer 13

CERAMIC

Question 14

aircraft can include cockpit
windows, instrument covers, or
lighting elements

Answer 14

GLASS

Question 15

An engine part is found to be structurally sound, it must be measured
to verify that it is within the manufacturer’s tolerances. This check is
referred to as a dimensional inspection and requires the use of
several precision measuring instruments such as

Answer 15

micrometer
calipers, telescoping gauges, and dial indicators.

Question 16

extremely precise measuring
tools for external measurements, most notably
thickness, though they can be used for
measuring small external diameters.

Answer 16

Micrometer Caliper

Question 17

indirect measuring
devices used to measure the internal
diameter of a bore, hole, groove, slot, etc.

Answer 17

Telescoping Gauge

Question 18

Used for precise comparisons or
measurements of workpiece surfaces,
machine, equipment, part tolerances,
alignment of your machine’s
components, or the general deviation
of any object from an expected
standard.

Answer 18

Dial Indicator

Question 19

After all of the parts have been inspected and repaired as necessary,
the engine is ready to be reassembled.

Answer 19

Reassembly

Question 20

After an engine has been repaired, overhauled, or replaced, it must be
prepared for installation.

Answer 20

Installation & Testing

Question 21

Once an engine is completely installed on an aircraft or test stand,
you can prepare the engine for a test run.

Answer 21

Ground Test Preparation

Question 22

To prevent engine bearing failure during the initial start, you should.

Answer 22

Pre-oiling

Question 23

Before you attempt to start a newly installed engine, the fuel system
should be bled to purge any air bub bles from the fuel lines and
pumps and to help flush any preservative oil from the fuel system.

Answer 23

Fuel System Bleeding

Question 24

If an aircraft has cowl flaps, they must be rigged to accurately
regulate the passage of cooling air through the engine compartment.

Answer 24

Cowl Flap Rigging

Question 25

After the initial ground run and flight test, an engine must receive final
adjustments and a thorough visual inspection.

Answer 25

Post-run Check and Adjustment

Question 26

An engine’s crankshaft rpm is displayed by a
that is calibrated in hundreds of
rpm. is a primary engine
instrument used extensively by a pilot to
monitor engine condition and verify that
the engine is developing the appropriate
rpm and power output for a given throttle
setting.

Answer 26

Tachometer/ Crankshaft Speed

Question 27

gauge
measures the absolute pressure of the
fuel/air mixture within the intake manifold.

Answer 27

Manifold Pressure

Question 28

The engine temperature can have a
dramatic impact on engine performance.
Therefore, most reciprocating engine
powered aircraft are equipped with a
cylinder head temperature (CHT) gauge
that allows a pilot to monitor engine
temperatures.

Answer 28

Cylinder Head Temperature

Question 29

is
measured at the carburetor entrance
by a temperature sensing bulb in the
ram air intake duct.

Answer 29

Carburetor Air Temperature

Question 30

allows a
pilot to monitor the temperature of
the oil entering the engine. This is
important because oil circulation
cools the engine as it lubricates the
moving parts

Answer 30

Oil Temperature

Question 31

The engine lubrication system
supplies oil under pressure to the
moving parts of the engine. To allow
a pilot to monitor the effectiveness

aircraft engines are equipped with an
oil pressure gauge that is calibrated
in pounds per square inch.

Answer 31

Oil Pressure

Question 32
