Q188. Which of the following should be avoided in parts selection to enhance the design reliability?
Response:

Selection of standard parts.

Selection of exotic technology parts.

Selection of redundant parts.

Selection of high reliability parts.

Q189. A high incidence of failures has developed during aircraft acceptance testing. The identified failure is that an instrument panel light has malfunctioned on 6 of the last 10 aircraft tested.
This problem needs to be investigated and a Failure Reporting and Corrective Action System (FRACAS) needs to be completed without stopping aircraft production.
If the cause of the failure is determined to be a faulty subassembly manufactured only by a single supplier, and this situation is threatening to shut down aircraft production, the next step should be to Response:

Visit the supplier to assist in determining the root cause of the problem.

Initiate a supplier corrective action and return all of the unsorted inventory.

Issue a Government and Industry Data Exchange Program (GIDEP) alert.

Update the inspection instruction and retrain receiving inspection.

Q190. A Pareto analysis of field failure data indicates that several significant failure categories are approximately equal in size. The BEST next course of action to take in selecting a category for improvement would be which of the following?
Response:

Take additional data until a more significant category is evident.

Select the category that offers the most overall cost saving.

Select the category that is easiest to fix.

Select the category that requires the least expense to fix.

Q191. A field test may be considered satisfactory if:
Response:

The design engineer can operate the equipment under all required conditions.

The reliability engineer can operate the equipment under all required conditions.

Alternate operators can operate the equipment under all required conditions.

The human factors engineers can operate the equipment under all required conditions.

Q192. Which of the following techniques is MOST efficient when two nuisance variables are to be averaged out in an experimental design?
Response:

Full factional.

Fractional factorial.

Latin square

Q193. If the reliability goal for a 4 – hour mission is 0.9999 for a complex system, what system MTBF is required?
Response:

55 hours.

2,500 hours.

10,000 hours.

40,000 hours.

Q194. The equation below represents

Response:

The limits for an X Bar control chart.

The limits for a Range chart.

The process capability adjusted for centering.

The probability of meeting specification.

Q195. Equivalence class partitioning is:
Response:

A black-box method that divides program functions into related groups for testing.

A white-box method that divides control paths into dependent and independent categories for testing.

A black-box method that divides the inputs to a program into classes from which test cases can be derived.

A white-box method that divides errors into classes to reduce the amount of testing required.

Q196. A Reliability Engineering Department is conducting a training needs assessment. Which of these techniques are used for a training needs assessment?
