Test your understanding of maintenance systems with 5 practice questions.

Practice Questions

Question 1

Which inspection method involves visual assessment of internal engine or structural components through remote imaging to detect wear and damage without disassembly?

Question 2

In vibration monitoring of rotating machinery, an amplitude peak at twice the shaft rotational frequency (2X) most likely indicates which fault condition?

Question 3

For an aircraft component subjected to $n_{1}=20\,000$ cycles at a stress level with fatigue life $N_{1}=100\,000$ cycles and $n_{2}=50\,000$ cycles at a level with $N_{2}=200\,000$ cycles, calculate the cumulative fatigue damage $D$ using Miner’s rule.

Question 4

Which nondestructive testing method uses infrared imaging to detect thermal anomalies that may indicate electrical or mechanical faults?

Question 5

Which type of built-in test (BIT) in avionics continuously runs during system operation to detect failures in real time?
