Why must torque wrenches be calibrated at regular intervals in aerospace maintenance?
Answer: To ensure fasteners are tightened to the correct specification, preventing under-torque failures or over-torque damage
Calibration ensures torque wrenches apply the exact specified force, since both under-torquing (loosening risk) and over-torquing (material damage) can cause catastrophic failures in aircraft.
What is the purpose of a borescope in aircraft maintenance?
Answer: To visually inspect internal engine components and confined spaces without disassembly
A borescope is a flexible or rigid optical instrument that allows technicians to visually inspect the interior of engines, fuselage cavities, and other confined spaces without disassembly.
When using an ohmmeter to test electrical continuity in aircraft wiring, what reading indicates a complete circuit?
Answer: Near-zero ohms resistance
A near-zero ohms reading on an ohmmeter indicates a complete, low-resistance circuit path (continuity), while infinite resistance (OL) indicates an open circuit.
What is the correct procedure for measuring aircraft fuel tank quantity with a drip stick?
Answer: Insert the calibrated stick into the tank sump until fuel wets it, then read the fuel level at the graduated markings
A drip stick (tank quantity gauge) is inserted through the sump fitting until fuel wets the calibrated portion, allowing the technician to read fuel quantity directly from graduated markings.
What does a multimeter measure that makes it essential in aerospace avionics troubleshooting?
Answer: Voltage, current, and resistance across electrical components and circuits
A multimeter measures voltage (V), current (A), and resistance (Ω), making it the fundamental tool for diagnosing electrical faults in aircraft avionics and wiring systems.
What is the purpose of using a tensiometer in aircraft maintenance?
Answer: To measure cable tension in flight control cables to verify correct rigging
A tensiometer measures the tension in flight control cables, allowing technicians to verify cables are rigged to the manufacturer's specified tension for correct control response.
