✍️ Sample Airframe Mechanic Certification Questions & Answers
1. Which rivet installation defect is called a 'clinched' rivet?
A clinched rivet occurs when the shank bends sideways rather than mushrooming outward, resulting in a bent shank and poor joint quality.
2. To verify the integrity of an electrical bond between an equipment rack and the aircraft structure, a technician should use a multimeter to measure for:
Electrical bonding ensures that all conductive parts of the aircraft are at the same electrical potential. A proper bond provides a path of least resistance for fault currents, lightning strikes, and static discharge. A test of a good bond is a measurement of very low resistance (typically in the milliohm range) between the two points.
3. Which material property describes a metal's ability to be drawn into wire without breaking?
Ductility is the ability of a material to deform plastically under tensile stress, allowing it to be drawn into wire.
4. When performing a repair on aircraft skin using a flush patch, the patch material must be:
Repair patches must match the original material specification (alloy and temper) to maintain the structural and corrosion properties of the original design.
5. What is 'misfueling' and what is a common serious consequence?
Misfueling means adding the wrong fuel type (e.g., Jet-A into an avgas piston engine), which can cause immediate engine failure, detonation, or serious internal engine damage.
6. An ice detector that uses a vibrating probe operates on which principle?
Vibrating-probe ice detectors sense ice accumulation by detecting the change in resonant frequency caused by added mass on the probe.
