AM Tools & Equipment Operation 2 — Questions and Answers
Question 1: What type of torque wrench requires the technician to watch a dial indicator while applying torque?
- Click-type torque wrench
- Dial-indicating torque wrench (Correct answer)
- Beam-type torque wrench
- Digital torque wrench
Correct answer: Dial-indicating torque wrench
A dial-indicating torque wrench uses a dial gauge that the technician monitors continuously while applying torque to a fastener.
Question 2: When using a rivet gun on an aircraft skin, the bucking bar should be held:
- At a 45-degree angle to the rivet
- Firmly and squarely against the rivet shank (Correct answer)
- Loosely to allow vibration absorption
- Against the manufactured head of the rivet
Correct answer: Firmly and squarely against the rivet shank
The bucking bar must be held firmly and squarely against the rivet shank to form a proper shop head and prevent rivet damage.
Question 3: A hydraulic press used in aircraft maintenance requires calibration records primarily because:
- Hydraulic fluid degrades over time
- Force output must be verified to ensure correct part installation tolerances (Correct answer)
- The press frame expands when heated
- OSHA requires all shop equipment to be logged
Correct answer: Force output must be verified to ensure correct part installation tolerances
Calibration records verify that the press delivers accurate force, which is critical when pressing bearings or bushings to specified interference fits.
Question 4: Which tool is used to measure the internal diameter of a cylinder bore in an aircraft engine?
- Outside micrometer
- Telescoping gauge and micrometer (Correct answer)
- Vernier caliper only
- Dial test indicator
Correct answer: Telescoping gauge and micrometer
A telescoping gauge is inserted into the bore and then measured with an outside micrometer to determine the internal diameter accurately.
Question 5: What is the purpose of a cherry picker (engine hoist) load rating placard in the maintenance hangar?
- It specifies the hoist's fuel capacity
- It informs technicians of the maximum safe working load (Correct answer)
- It records the last inspection date only
- It lists approved engine models for the hoist
Correct answer: It informs technicians of the maximum safe working load
The load rating placard specifies the maximum safe working load so technicians do not overload the hoist and cause equipment failure or injury.
Question 6: When drilling through aluminum aircraft skin, which drill speed principle generally applies?
- Lower RPM for thin aluminum to prevent work-hardening
- Higher RPM and lower feed rate for soft metals like aluminum (Correct answer)
- Fixed RPM regardless of material thickness
- Higher feed rate with lower RPM to reduce heat
Correct answer: Higher RPM and lower feed rate for soft metals like aluminum
Soft metals like aluminum are best drilled at higher RPM with a controlled, lower feed rate to produce clean holes and prevent material deformation.
Question 7: A dye penetrant inspection kit used in aircraft maintenance must be stored:
- In direct sunlight to maintain chemical activity
- Away from heat sources and in accordance with the manufacturer's temperature range (Correct answer)
- Near the aircraft to reduce handling time
- In the same cabinet as flammable solvents for convenience
Correct answer: Away from heat sources and in accordance with the manufacturer's temperature range
Dye penetrant chemicals are temperature-sensitive and may be flammable, so they must be stored within the manufacturer's specified temperature range away from ignition sources.
