• Temperature Extremes

• Light

• Stationary Loads

• Controlled Locations

Aircraft have different stresses on fasteners than most other industries. What factors can effect fasteners in dynamic environments and require us to be that much more vigilant when we work with fasteners?

• Fluctuating Loads

• Wet (in water)

• Stationary Loads

• Controlled Locations

What is actually happening as a fastener gets torqued that is being quantified?

• Fastener stretch

• Fastener Tightness

• Fastener clamp

• Material clamp

What are the common units of measure in aviation for torquing fasteners? (More than one correct answer)

• Nm = Newton meter

• cNm = Centi Newton meter

• in. lbs. = inch pounds

• cNm = Centi Newton meter

• ft. lbs. = foot pounds

What can help with issues of break away torque?

• Apply torque in steps

• Use smooth movements to apply torque

• Reset the fastener to an appropriate position

• Use an extension to apply a higher torque setting than required

Click type torque wrenches can be used by placing your hand on any part of the torque wrench to apply torque.

• True

• False

What statement is true of Fiction Drag Torque?

• Must be added to the torque value that is required for the application

• Is only for fasteners that are torqued on engines or propellers

• Can be calculated using the formula found in the AC 43 13

• Is minimal in value and can be omitted when calculating torque values

What are we trying to achieve with a torque wrench?

• Proper Clamping Force

• Torque 

• Squeeze

• Reduced Friction

Where should you go for torque information if you can't find the torque required for a fastener in the Aircraft Maintenance Manual?

• If it's not in the Manual, it's not important

• AMM

• AC 43.13-1B

• Technical Standard Order
