LOG 104 MODULE 5
1. Which of the following actions can be classified as "Maintenance?" Select the two alternatives that apply.:
1.*** Replacing a part that has failed.
2. **** Fixing a part that has been damaged.
2. Which of the following describes "maintainability?"
Select the two alternatives that apply.: 1.*** Incorporating diagnostics into the design that permits the monitoring
of a part's status.
2. *** The rapid diagnosis and removal of faults.
3. Which of the following provides the best description of the difference be- tween maintainability and
maintenance?: Maintainability is a design character- istic, while maintenance is the act of restoring or retaining a
system to a specified condition.
4. Which of the following design elements contribute to a system's maintain- ability design by providing a
capability to identify and diagnose a failure and facilitating a repair?
Select the two alternatives that apply.: 1.*** Diagnostics.
2.*** Human Factors.
5. A system's built-in testing (BIT) indicates that a part is not functioning correctly. When it is shipped to the
depot for repairs, tests indicate that the part is working within normal parameters.
This type of diagnostic indicates which of the following diagnostic problems?-
: Re-test OK (RTOK).
6. A pilot notices that the engine fire warning lamp in her UH-60 Blackhawk helicopter is lit an hour into a flight.
Knowing that the built-in testing (BIT) has a tendency to develop intermittent connections with the sensors, the
pilot bangs on the indicator, and the light goes out. Believing the aircraft is fine, the pilot completes the mission.
The pilot has apparently experienced which of the following diagnostic prob- lems?: BIT false alarm.
7. Which of the following is the worst case scenario when there is a diagnostic system malfunction?: Diagnostics
report no problem, and there really is a problem.
8. What will the D-level diagnostics tell you about the circuit board just dis- cussed?: The board is out of
tolerance.
