13. A reviewer finds conflicting evidence about Pitot-static, gyroscopic, electronic-flight and warning instruments for safe, accurate work in aircraft systems and
during a pre-task planning review. What should happen first? Case EB-2769-0013: 9 checks are complete, 1 item(s) remain open, 1 supporting record(s) are
available, the last review was 11 hour(s) ago, and the current result differs from the prior baseline by 8 unit(s).
A. Treat the issue as administrative and continue while the evidence remains unresolved.
B. Pause acceptance, compare Pitot-static, gyroscopic, electronic-flight and warning instruments for safe, accurate work with the approved criteria, investigate
the variance, and retain a traceable decision record.
C. Rely on an experienced colleague's verbal assurance instead of obtaining objective evidence.
D. Defer the unresolved point until the task is complete and document it retrospectively.
Correct Answer: B
Explanation: The best answer verifies Pitot-static, gyroscopic, electronic-flight and warning instruments for safe, accurate against current requirements and
evidence before acceptance. With 1 open item(s), 1 supporting record(s), and a 8-unit change from baseline, a traceable foundational decision should resolve
the discrepancy rather than defer, bypass, or redefine the control.
14. A reviewer finds conflicting evidence about Powerplant controls, indications, limitations and abnormal symptoms through realistic aircraft systems and
during a pre-task planning review. What should happen first? Case EB-2769-0014: 7 checks are complete, 2 item(s) remain open, 5 supporting record(s) are
available, the last review was 24 hour(s) ago, and the current result differs from the prior baseline by 6 unit(s).
A. Check calibration and method controls affecting Powerplant controls, indications, limitations and abnormal symptoms through realistic, investigate the
unexpected indication or result, and document a defensible disposition.
B. Accept the result if it matches the expected outcome, even when a control check is invalid.
C. Ignore equipment or environmental checks when the operator is experienced with the method.
D. Change the test sensitivity or acceptance limit without authorization to reduce false indications.
Correct Answer: A
Explanation: The best answer verifies Powerplant controls, indications, limitations and abnormal symptoms through realistic against current requirements and
evidence before acceptance. With 2 open item(s), 5 supporting record(s), and a 6-unit change from baseline, a traceable foundational decision should resolve
the discrepancy rather than defer, bypass, or redefine the control.
15. A reviewer finds conflicting evidence about System interaction, checklist use and fault-isolation logic with emphasis on boundaries and responsibilities in
during a pre-task planning review. What should happen first? Case EB-2769-0015: 5 checks are complete, 3 item(s) remain open, 2 supporting record(s) are
available, the last review was 13 hour(s) ago, and the current result differs from the prior baseline by 4 unit(s).
A. Bypass the protective control temporarily so the task can be completed on time.
B. Stop or control the affected activity, assess the hazard associated with System interaction, checklist use and fault-isolation logic with emphasis on
boundaries and, apply the approved safeguard, and verify conditions before restarting.
C. Assume the abnormal condition is acceptable because no injury or damage has occurred yet.
D. Record the hazard after completion but do not interrupt the current operation.
Correct Answer: B
Explanation: The best answer verifies System interaction, checklist use and fault-isolation logic with emphasis on boundaries against current requirements and
evidence before acceptance. With 3 open item(s), 2 supporting record(s), and a 4-unit change from baseline, a traceable foundational decision should resolve
the discrepancy rather than defer, bypass, or redefine the control.
