The picture shows a torque wrench with an extension. To apply a torque of 350 lb.in. the reading on the dial should be
- 245 lb.in.
- 280 lb.in.
- 350 lb.in.
why?
The UK standard of limits and fits is
- BS4500.
- BS8888.
- BS308.
Question need revising BS4500 is now withdrawn.

If an ammeter reads 0 - 1mA FSD, what would you be required to do to enable it to read 10mA FSD?
- Place a 5.8 ohm resistor as a shunt in parallel with the meter.
- Place a 9.9 ohm resistor as a multiplier across the coils.
- Place a 9 ohm resistor as a multiplier in series with the meter.
Can someone explain pls?
A Dial Test Indicator may be used for
- checking a round bar for bow.
- checking dimensions to within 0.125 inch.
- checking any known depth measurement.
D.T.I why isnt the 3d option?Because it says "any"?
What is the minimum bend radius of a loom adequately supported at a terminal block?
- 10 * diameter
- 8 * diameter
- 3 * diameter
why is 3*d and not 8*d?
What non-destructive testing method requires little or no part preparation, is used to detect surface or near-surface defects in most metals, and may also be used to separate metals or alloys and their heat-treat conditions?
- Eddy current inspection.
- Magnetic particle inspection.
- Ultrasonic pulse inspection.
isnt eddy current inspecction method only for internal cracks?Why does it mention here that it is used to detect"surface and nearsurface"?
When tapping blind holes
- a set of three taps is used.
- a set of two taps is used.
- a single bottoming tap is used.
what does 3 taps mean?
Springs are manufactured from
- high carbon alloy steel with high strength requirements.
- low carbon alloy steel with high strength requirements.
- high carbon alloy steel with low strength requirements.
i think in module 6 it literally said that the correct answer was "high carbon alloy steel with low strength requirements" am i wrong?Or did i get confused?
If the outer cover of a flexible hose is found to be cracked.
- It is unserviceable due to possible flow restriction.
- It may still be serviceable.
- It is unserviceable since it may leak.
shouldnt it be unservicable?
A secondary earth is
- not less than 0.5mm.
- 18 AWG.
- 22 AWG.
i dont understand
Following a major defect the C of A
- is not affected, however may run out on a time basis.
- will be invalidated and requires a full renewal survey before flight.
- Nothing will happen and the C of A remains fully valid.
i dont undersrand the question help please.
Once a person has been disconnected from the source of an electrical shock the next step should be
- seek medical assistance from qualified personnel immediately.
- check for breathing start AR if necessary.
- check for a pulse and start cardiac massage if necessary.
Please write your question here.
What does the cut of a file refer to?
- Arrangement of the teeth.
- Number of teeth per inch.
- Grade of material used.
Please write your question here.
A crimped electrical connection is suspected to be high resistance. How would you verify this without disconnecting the circuit?
- Measure the millivolt drop across the connection with a millivolt meter.
- Check the resistance across the connection using an ohmmeter.
- Apply a 250 volt megger test across the crimped terminal.
how to measure with an millivolt meter without disconnecting the circuit?!!!
On a pre flight check you notice an instrument glass is cracked. You should
- record it in the tech log.
- check MEL.
- inform the flight crew.
hi guys, as i know , for every defect you hav to enter into techlog first , and after check the MEL and rise a HIL
What is the normal spacing between rivets?
- 2 D.
- 3 D.
- 4 D.
wasn't it from 3 to 10 times the diameter?
To prevent wet arc tracking
- cable grips should be kept tight.
- ensure hot stamp printing is controlled.
- cables should not be excessively stretched.
Why is it?
When drilling out a rivet, use a drill
- larger than the rivet hole.
- same size as the hole.
- smaller than the rivet hole.
thought it was smaller than hole when drilling out the rivet??
When drilling out a rivet, use a drill
- larger than the rivet hole.
- same size as the hole.
- smaller than the rivet hole.
according to CAAIP it should be smaller than the shank of the rivet when removing rivet.
Galvanic corrosion refers to a type of
- corrosion between two pieces of material.
- electrochemical plating process between metal layers.
- uniform surface corrosion across the exposed area.
"two pieces of material" - this is a sloppy question - one piece of "material" could be plastic and the other metal!
If there is a positive allowance between the smallest possible hole and the largest possible shaft, the fit is known as
- a transition fit.
- a clearance fit.
- an interference fit.
I think this question is wrong, I think the answer should be interference fit, please check
What is the allowable reaction on a rivet?
- 2D
- 1D
- 1.5D
Could anyone help with this question? I couldnt find what allowable reaction is... Thanks a lot
When checking a torque wrench 15 inches long, the load required to give torque of 120 lbs.in. is
- 6 lbs.
- 8 lbs.
- 10 lbs.
I have a question on how we do this calculation? Thanks
At which frequency is the calibration of frequently used crimping tools carried out?
- Bi-annually (every two years)
- Annually (once per year)
- Every 1000 crimps
How do I know when 1000 crimps were made?
The right answer should be every x time?
To replace one 1/8 inch rivet
- three 1/16 inch rivets would be required.
- two 1/16 inch rivets would be required.
- four 1/16 inch rivets would be required.
I know of no such procedure where this method would be employed please explain
