Miscellaneous
If you remove or replace a component, or rig a flight control, what must you do afterwards?
Do whatever checkout is called for in the MM.
What are the flaps that are usually on the leading edge?
Kruger flaps.
If you crash your plane into a blast fence, what do you need to do afterward (I mean, after the pee test)?
You would need to check the rig.
what is the purpose of a pulley?
To allow the cable to change direction.
What is the result to the pilot of a flight control out of balance?
What is acceptable for cutting a cable? What is not acceptable?
Chisel or cutters.
Grinding wheel, cutoff wheel, torch, hacksaw.
Add or remove washer/shims; rotate an eccentric bushing, replace worn hardware
What can go wrong if control cable tension is too loose?
The control surface will not travel as much as expected, which could cause a crash.
What must every pulley have?
A cable guard to keep the cable from slipping off.
If you find a flight control out of balance what would you need to do to fix it?
Either add weight by adding pieces of lead or uranium; or subtract weight by removing some metal.
Name one advantage and one disadvantage of fly by wire systems.
Advantages: lighter weight, easier routing; additional safety by having computers limit movements of flight controls.
Disadvantage: subject to EMF.
A balance spring is an example of what kind of system?
Artificial feel.
How far must your tensionmeter be from any connection point?
6"
If the bearing on a pulley seizes, what will the pulley look like?
It will have a groove worn into it from the cable rubbing on a stationary pulley.
Besides being out of balance, what else can cause flutter?
Worn attach fittings and incorrect cable tension.
How many threads can show on a properly tensioned turnbuckle?
3 on each side.
A valve for a hydraulic actuator; a control horn for a flight control; a bellcrank.
When you are checking cable tension, what environmental factor must you check first?
Air temperature.
What does a fairlead do and what is maximum deflection through a fairlead?
It routes cables through the aircraft structure; 3 degrees.
What does it mean for a flight control surface to be in static balance?
It means it can remain stationary when supported at the center of gravity.
Can you use self locking nuts on a push/pull rod? If not, is there something else to use?
No.
Castle nut with cotter pin.
What are wash-in and wash-out?
Wash in is where the aft tips of the wings are pulled down;
Wash out is where the aft tips of the wings are allowed to rise up.
What is meant by tramming wings?
Making sure they're squared up to specifications.
If a pulley is too tight, what is the effect on the flight control?
It will be hard to move.
What is a maintenance action that might require rebalancing a flight control?
Painting it.
