Immediately after installing a new set of piston rings, the most likely reason for excessive blow-by could be. improper valve seating. insufficient end gap. worn valve guides. failure to stagger the ring gaps.

On a twin-engine aircraft with fuel-injected reciprocatlng engines, one fuel flow indicator reads considerably higher and the other ln all engine operatlng configuratlon. What Is the probable cause of this indication. carburetor lcing. alternate alr door stuck open. excessive Intake valve clearance. one or more fuel nozzles are clogged.

What is the type of connecting rod normally used on a horizontal opposed engine. ball type. plain type. fork and blade type. master and artlculated type.

The piston ring installed below the compression rings is called. oil scraper ring. oil control ring. oil wiper ring. none of the above.

Cylinders that have been chrome plated are identified by. green paint. white paint. blue paint. orange paint.

If a 0.003 oversize stud is ldentified by the prefix PO03 after the part number, what will be the color painted on the stud. Orange. Red. White. none of the above.

A six-ylinder engine with a bore of 4.375 inches anda stroke of 5.125 inches has a piston displacement of. 422.6. 462.25. 1649.0. 1849.0.

______is simply a reference posltlon on a propeller blade that ls speclfied distance from the center of the hub. the blade datum point. the blade center of gravity. a blade center of pressure. a blade statlon.

The actual distance a propeller moves through the alr In one revolutlon is known as. the effective pitch. the relatlve pltch. the resultant pitch. the geometrlc pitch.

In reference to propellers, slip is known as the difference between. the propeller pitch and the dymamic pitch. the geometric pitch and the efective pitch. the propeler pitch and the effective pitch. the propeller pitch and the aerodnamic pitch.

In cruising flight, a propeer will normaty be operating in. the alpha range. the beta range. the theta range. the negative thust range.

Tractor propellers are mounted. On the front of an engine and pull the aircralt through the air. On the front of an engine and push the aircraft through the air. On the aft end of an engine and pulI the aircraft through the air. On the aft end of an engine and push the aircraft through the air.

The most efficient angle of attack of a propeller blade is in the range of. -2° to +2°. +2 to +4°. +4 to +8°. +8° to +10°.

A propeller blade cuff. distributes anti-Hcing fluld. strengthens the propeller blade. reduces drag. Increases cooling alr flow.

Which of the following occurs to cause front cone bottoming during propeller installation. the front cone becomes bottomed in the front propeller hub cone seat before the rear propeller hub cone seat has engaged the rear cone. the front cone becomes bottomed in the front propeller hub cone seat before the retaining nut has engaged sufficient threads to be safetied properly. the front cone enters the front propeller hub cone seat at an angle causing the propeller retaining nut to appear tight when it is only partlally tightened. the front cone contacts the ends of the shaft splines, preventing the front and rear cones from being tightened against the cone seats In the propeller hub.

Normally, for a light alreraft with metal propellers of up to approximately 6 feet In diameter, the propellers can be out of track no more than. 1/2´´. 1/16´´. 1/8´´. 1/4´´.

In cruising fight, at a costant RPM. the propeller is on its high pith stoo. the centrifugal force of the governor fyweights is less than the force of the speeder spring. centritugal force of the governor fyweights balance the force of the speeder spring. certrifugal force of the governor fyweights exceeds the force of the speeder spring.

Prope Tler Synchronising systems ae interded to ersure that all propellers. operate at the same RPM. produce the seme thrust. maintain theit angular relationshios. maintain the same angle of attak.

An aircraft's propeBer system beta tange. Is used to produce zero or negative thrust. is the pitch tange used for cruising speeds. Is used to xhieve marimun thrust during takeoff. refers to the most fuel effcient pich range to use at a given RPM.

If a hydraulic propeller is feathered and then immediately unleathers Itself, a probable cause of the trouble is that the. governor is not cutting out in high pch. pressure cutout switch s struck In the closed position. distributor relief valve is struck in the closed position. dome pressure relief valve is struck in the closed position.

Proper operation of the electic deicing boots on individual propeller blades may be'best determined by. feeling the boots to see if they are heating. observing the ammeter or loadmeter for current flow. timing the inflation and deflation sequence. checking the ammeter for flickering and feeling the boots for sequence of heating.

What does the piston connect to?. It connects to the connecting rod by a piston pln (REF 1-16 PP). It connects to the connecting rod by a piston pln (REF 1-16 PP).

What to do when a turbine engine catches fire during a start?. Turn off fuel (pull flre handle) and continuecranking (REF 11-20 PP). Turn off fuel (pull flre handle) and continue cranking (REF 11-20 PP).

Turbocharger speed control is achleved from?. Wastegate positlon (REF 5-9 PP). Wastegate positlon (REF 5-9 PP).

These types of bearings are ldeal because they resist high temperatures. Ball and Roller bearings (REF 3-33 PP). Ball and Roller bearings (REF 3-33 PP).

Cowl position during ground run?. Open (REF AF 1-22). Open (REF AF 1-22).

condenser on a spark plug is called?. Booster. Booster.
