FAA Powerplant Written Practice Test

In engine maintenance, what is the consequence of not addressing metallic particles in the oil filter?

1. It can lead to minor performance issues

2. It poses no risk to the engine

3. It may result in engine failure if not corrected

4. It only requires visual monitoring

The correct answer is: It may result in engine failure if not corrected

The presence of metallic particles in the oil filter is a significant indication of potential problems within the engine. These particles usually arise from wear or damage to engine components, such as bearings, gears, or other moving parts. If these particles are not addressed, they can circulate through the engine, causing increased wear on internal components. Over time, this can lead to more severe damage, ultimately resulting in catastrophic engine failure if the underlying issues are not corrected. This makes it critical to regularly inspect the oil filter for such contaminants and take appropriate action to maintain engine integrity and performance. Monitoring for metallic particles is not sufficient by itself; they indicate an urgent need for maintenance or repair to prevent serious consequences.
