1. A failure that leaves the system fully functional is:
Response:

A) A minor failure.
B) A major failure.
C) A chronic failure.
D) A nuisance failure.

2. The optimum cost point for total life cycle costs occurs:
Response:

A) When operations and maintenance costs are minimized.
B) When acquisition costs plus ongoing costs are minimized.
C) When manufacturing and development costs are minimized.
D) When reliability program expenditures are maximized.

3. Which of the following tools are classified as structured root cause analysis tools?
I. 5P.
II. 7D, 8D or 9D problem solving.
III. Management oversight and risk tree analysis (MORT).
IV. Human performance evaluation system (HPE)
Response:

A) I, II and IV only
B) II and III only

4. For a high compression aircraft air conditioning system, the MTBF is 100 hours. This mean life is allocated for four serial units comprising the total system. The unit failure rates are then weighted as follows:
w 1 = 0.1250 w 3 = 0.1875
w 2 = 0.2500 w 4 = 0.4375
Based upon the above data, indicate which of the following is the correct calculation for one of the units.
Response:

A) λ 3 = 0.0018750
B) λ 2 = 0.0025100
C) λ 4 = 0.0435700
D) λ 1 = 0.0125000

5. A data collection, analysis, and reporting system should:
I. Permit detailed failure and failure rate analysis for varying environments, time periods, storage conditions, etc.
II. Provide distinction between items that failed and item that were wrongly removed.
III. Report data on successes as well as failures.
Response:

A) II and III only
B) I and III only
C) I, II and III
D) I only
