What action should the Power Plants Supervisor take if contamination is detected?

The most appropriate action for the Power Plants Supervisor when contamination is detected is to assist Quality Assurance (QA) in an immediate investigation. This response is crucial because contamination in fuel or engine systems can severely impact aircraft safety and performance. By collaborating with QA, the supervisor helps ensure that the issue is thoroughly assessed, potential sources of contamination are identified, and necessary corrective measures are implemented to mitigate risks. This teamwork is essential in maintaining the integrity of aircraft operations and ensuring compliance with safety standards.

In addressing contamination effectively, the supervisor prioritizes immediate action to protect the aircraft and personnel, as contamination can lead to engine failures or dangerous operational conditions. Engaging QA allows for an organized approach to identifying whether the contamination originated from fuel sources, maintenance practices, or other areas, leading to a more systematic solution.
