Powerplant - AM.III.A.K8 - Reciprocating engine maintenance and inspection

Question 1

What must be inspected to determine the airworthiness of an reciprocating engine installation? (6)

Answer 1

• the propeller
• lubrication system
• ignition system
• fuel metering system
• cooling system
• exhaust system

Question 2

Where can you find the correct grade of fuel and amount of engine lubricating oil for an aircraft reciprocating engine?

Answer 2

In the type certificate data sheets for the aircraft

Question 3

What are the basic steps in troubleshooting a reciprocating engine installation? (4)

Answer 3

• know how the system should operate
• observe how the system is operating
• divide the system into smaller parts to find the trouble
• look for the obvious problems first

Question 4

Where do you find instructions for removing a reciprocating engine from an aircraft?

Answer 4

In the aircraft maintenance manual

Question 5

What must normally be done to a nose wheel airplane before removing a reciprocating engine?

Answer 5

The tail of the aircraft must be supported

Question 6

What should be used to cover the ends of fuel and oil lines that have been disconnected from a reciprocating engine?

Answer 6

• the correct plugs or caps
• never cover the end of a line with tape

Question 7

What is meant by a QEC reciprocating engine?

Answer 7

• An engine that has been prepared for a quick engine change
• The engine is on its mount and all of the accessories are installed
• a minimum of time is required to change engine
• all that is needed is for the controls, wiring and fluid lines to be connected to the firewall

Question 8

What is meant by rigging the reciprocating engine controls so they have some cushion?

Answer 8

• the control on the engine component must contact its stop before the control handle in the flight deck
• this causes the travel in the control handle to spring back a slight amount when it is moved to the extent of its travel

Question 9

What are two ways of pre-oiling a reciprocating engine?

Answer 9

• before the spark plugs are installed and after the oil tank or sump is filled, turn the engine over with the starter until oil runs out of the fitting to which the oil pressure gauge connects
• use a pre-oiler tank. air pressure forces oil through all of the passages until some of it flows from the oil pressure gauge fitting
