Reciprocating Engine Operation, Maintenance, Inspection, And Overhaul

Front 1

What indications are given in the event of a leaking or open primer while the engine is running.

Back 1

The engine will not idle properly

Front 2

A cold cylinder is found when troubleshooting a running engine. What does this indicate.

Back 2

No combustion in that cylinder

Front 3

Front 4

When pulling a propeller through, a hissing sound is heard, indicating valve blow-by, what procedure should be perform next?

Back 4

A compression check should be performed to identify the faulty cylinder

Front 5

What is the purpose of performing a compression test?

Back 5

To determine if the valves, pistons and rings are sealing properly.

Front 6

When an engine is overhauled, how is it total time affected? When an engine is rebuilt, how is its operating history affected?

Back 6

The total time on the engine must be continued and the time since major overhaul is entered into the engine log. If the manufacture rebuilds the engine, it is granite a zero time status and is considered to have no previous operating history.

Front 7

What inspections should be performed after a propeller strike without sudden stoppage?

Back 7

1. Inspect engine mounts, the crank case, and the nose section for damage.

2. Inspect the oil and Oil filters/screens for metal particles.

3. Inspect the crankshaft or driveshaft for the cracks and misalignment.

Front 8

When inspecting a piston, where are the cracks most likely to be found?

Back 8

In those areas that are highly stressed; usually the base of the piston bosses, inside at the junction of the bore and the walls, and the ring lands.

Also likely to occur Where the the piston pin/wrist pin connects. The metal is thinnest at this location.

Front 9

What does it mean if an engine part is within “serviceable limits”?

Back 9

It means that the part is within the manufacturers limits and can be used in an engine (does not require replacement).

Front 10

Name some of the precautions that should be performed prior to engine removal.

Back 10

Disconnect the battery, turn off to fuel valves, chock the wheels, and if necessary, install a tail stand.

Hint 10

Name some of the precautions that should be performed prior to engine removal.

Front 11

What tools or instruments are used to inspect the cylinder barrel for out-of-Roundness?

Back 11

A dial indicator or an inside micrometer is usually used to measure the top of the cylinder and at the skirt. A telescopic gauge and micrometer can also be used. Two readings should be taken at 90° to each other.

Front 12

How can a loose stud in an engine crankcase be repaired?

Back 12

Remove the loose stud and inspect the hole for size and thread condition. It may be necessary to use an oversize study or a Heli-coil.

Front 13

What publication is used to check an engine for normal operation?

Back 13

Manufactures maintenance manual.

Front 14

A week cylinder is found during a compression check. What must be inspected?

Back 14

The inside of the cylinder.

Front 15

What publications can be used as a guide for 100 hour inspections on aircraft engines?

Back 15

Manufacturers maintenance manuals and FAR part 43, appendix D.

Front 16

How do you identify the engine serial number?

Back 16

It is on the engine data plate.

Front 17

Prior to returning a reciprocating engine to service after a 100 hour inspection, what operational checks must be performed?

Back 17

Check the power output (static and idle RPM), check magnetos, fuel and oil pressure check, cylinder and oil temperature check.

Front 18

What purpose does an oil analysis serve?

Back 18

Metal particles in the oil show normal and abnormal wear of the engine. This helps in evaluating the engines internal condition.

Front 19

What inspection should be performed on an engine that has been in storage?

Back 19

Perform an inspection to determine if there is any corrosion damage.

Front 20

Where would a carburetor air temperature bulb be located?

Back 20

In the ram air intake duct.

Front 21

What is the fuel pressure range on float type carburetors

Back 21

3 to 5 psi.

Front 22

Where is the fuel flow indicating system generally connected within a carbureted reciprocating engine?

Back 22

Between the engine fuel pump and the carburetor.

Front 23

Name the basic components of a fuel flow system?

Back 23

The transmitter and the indicator.

Front 24

What unit of measure is generally used to indicate fuel flow?

Back 24

Pounds or gallons per hour.

Front 25

Why is fuel flow monitor?

Back 25

To determine fuel consumption and engine performance.

Front 26

What does the manifold gauge indicate and how is it calibrated?

Back 26

It measures the absolute pressure in the engine manifold and is calibrated in inches of mercury.

Front 27

What directly controls manifold pressure?

Back 27

Throttle opening an engine RPM.

Front 28

During engine operation, where should the propeller control be set when checking the manifold pressure?

Back 28

Low pitch, high rpm.

Front 29

Is the aircraft electrical system required to power a cylinder head temperature gauge?

Back 29

No. A thermocouple is used as the electrical source.

Front 30

What are the possible indications of an oil pressure transmitter or indicator malfunction?

Back 30

A severe or sudden drop in oil pressure while the oil temperature remains normal and the oil supply remains full.

Front 31

What does a tachometer indicate on a reciprocating engine?

Back 31

Engine RPM.

Front 32

Where should the thermocouple be installed on a reciprocating engine using a single probe cylinder head temperature system?

Back 32

On the hottest cylinder.

Front 33

What should be done to a nose wheel airplane before removing the engine?

Back 33

Support the tail of the airplane.
