Question 1

When handling phosphate ester-based hydraulic fluids (such as Skydrol) during aircraft maintenance, which of the following safety practices is mandatory?

Wearing butyl rubber gloves, eye protection, and using dedicated Skydrol-compatible seals (such as ethylene propylene) Using standard nitrile rubber gloves and petroleum-resistant Buna-N seals for all system components Washing accidental skin contact immediately with mineral spirits or chlorinated solvent cleaners Using neoprene personal protective equipment and standard natural rubber workshop hoses

Correct Answer:

Wearing butyl rubber gloves, eye protection, and using dedicated Skydrol-compatible seals (such as ethylene propylene)

Question 2

During servicing of an aircraft high-pressure gaseous oxygen system, which precautionary rule must be strictly observed to prevent catastrophic spontaneous combustion?

Open the oxygen cylinder shutoff valve rapidly to create a sudden pressure surge that clears line debris Ensure all tools, fittings, and technician hands are completely free from hydrocarbon oils, greases, and organic contaminants Lubricate the oxygen bottle charging manifold threads with standard petroleum-based anti-seize grease Charge the system at the highest available flow rate to minimize adiabatic compression cooling

Correct Answer:

Ensure all tools, fittings, and technician hands are completely free from hydrocarbon oils, greases, and organic contaminants

Question 3

A torque wrench has an effective lever length (L) of 15 inches. An extension adapter of length (E) equal to 5 inches is attached in-line extending directly beyond the drive head. To apply a specified torque of 120 lbf·in to a critical airframe bolt, what torque setting must be set on the wrench dial?

160 lbf·in 120 lbf·in 90 lbf·in 100 lbf·in

Correct Answer:

90 lbf·in

Question 4

When torquing a structural bolt secured by an all-metal self-locking nut, how must the prevailing (run-on) torque of the nut be incorporated into the final tightening torque?

The measured prevailing torque must be subtracted from the standard design torque specified in the maintenance manual Prevailing torque is neglected if the fastener diameter is less than 0.375 inches The torque wrench must be calibrated to zero while rotating the nut across the prevailing section The measured prevailing torque must be added to the standard design torque specified in the maintenance manual

Correct Answer:

The measured prevailing torque must be added to the standard design torque specified in the maintenance manual

Question 5

According to standard aircraft maintenance practices, what is the required pitch (rate of twist) and direction of pull when applying the double-twist wire locking method to standard fasteners?

6 to 8 twists per inch, with the wire routed so that any loosening tendency of the fastener pulls the wire into tension and tightens the adjacent fastener 3 to 4 twists per inch, with the wire routed clockwise regardless of bolt thread direction 10 to 12 twists per inch, with the wire routed in a loose loop to allow thermal expansion 6 to 8 twists per inch, with the wire routed so that it creates a shearing force perpendicular to the bolt head

Correct Answer:

6 to 8 twists per inch, with the wire routed so that any loosening tendency of the fastener pulls the wire into tension and tightens the adjacent fastener
