Engine Inspection and Engine Instrument Systems Test 2

Which of the following conditions is usually not acceptable to any extent in turbine blades?

• Dents.

• Pits

• Cracks

The RPM indication of a synchronous ac motor tachometer is governed by the generator

• frequency.

• current.

• voltage.

Basically, the indicator of a tachometer system is responsive to change in

• current flow.

• voltage.

• frequency.

In regard to using a turbine engine oil analysis program, which of the following is NOT true?

• It is best to start an oil analysis program on an engine

  when it is new.

• A successful oil analysis program should be run over an engine's total operating life so that normal trends can be established.

• Generally, an accurate trend forecast may be made after an engine's first oil sample analysis.

The principal fault in the pressure type fuel flowmeter indicating system, installed on a horizontally opposed continuous-flow fuel injected aircraft reciprocating engine, is that a plugged fuel injection nozzle will cause a

• higher than normal fuel flow indication.

• lower than normal fuel flow indication.

• normal operation indication

Select the Airworthiness Directive applicability statement which applies to an IVO 355 engine, serial number T8164, with 2,100 hours' total time and 300 hours since rebuilding.

• Applies to all IVO 355 engines, serial numbers T8000 through T8300, having less than 2,400 hours' total time.

• Applies to all IVO 355 engines, serial numbers T8000 through T8900 with 2,400 hours or more total time.

• Applies to all I.O. and TV10-355 engines, all serial numbers regardless of total time or since overhaul.

If the thermocouple leads were inadvertently crossed at installation, what would the cylinder temperature gauge pointer indicate?

• Moves off scale on the high side of the meter

• Moves off scale on the zero side of the meter.

• Normal temperature for prevailing condition.

A complete break in the line between the manifold pressure gauge and the induction system will be indicated by the gauge registering

• lower than normal for conditions prevailing.

• zero.

• prevailing atmospheric pressure.

The engine pressure ratio (EPR) indicator is a direct indication of

• engine thrust being produced.

• pressure ratio between the front and aft end of the compressor.

• ration of engine RPM to compressor pressure.

What would be the possible cause if a gas turbine engine has high exhaust gas temperature, high fuel flow, and low RPM at all engine power settings?

• Turbine damage or loss of turbine efficiency.

• Fuel control out of adjustment.

• Loose or corroded thermocouple probes for the EGT indicator.
