AFE Maintenance Planning & Reliability Engineering

Question 1

What is the primary goal of Reliability-Centered Maintenance (RCM)?

Accepted Answer

Preserve system function by selecting appropriate maintenance strategies

Answer

RCM aims to preserve system function by identifying the most effective maintenance strategy for each failure mode rather than eliminating maintenance or reducing staff.

Question 2

Which maintenance strategy involves replacing components at fixed time intervals regardless of their condition?

Accepted Answer

Preventive (time-based) maintenance

Answer

Preventive (time-based) maintenance schedules replacement or servicing at fixed intervals regardless of the component's actual condition.

Question 3

Mean Time Between Failures (MTBF) is best described as:

Accepted Answer

The average operating time between successive failures of a repairable system

Answer

MTBF measures the average elapsed time between failures of a repairable system, serving as a key reliability metric.

Question 4

In a Failure Mode and Effects Analysis (FMEA), what is the Risk Priority Number (RPN) calculated from?

Accepted Answer

Severity × Occurrence × Detection

Answer

RPN = Severity × Occurrence × Detection; it prioritizes failure modes so maintenance resources are directed at the highest-risk items first.

Question 5

Which condition-monitoring technique uses sound waves to detect bearing defects and lubrication issues?

Accepted Answer

Ultrasonic testing

Answer

Ultrasonic testing detects high-frequency sound emissions from bearing defects, leaks, and lack of lubrication that are inaudible to the human ear.
