What should you do if you observe fluctuating oil pressure readings?

Fluctuating oil pressure readings can indicate a serious issue with the engine, such as oil starvation, which may lead to catastrophic engine failure if not addressed promptly. Performing an emergency engine shutdown is essential in this situation to prevent potential engine damage due to inadequate lubrication.

Shutting down the engine mitigates the risk of overheating and damage caused by insufficient oil pressure. This action is a crucial safety precaution and allows the operator to address the underlying issue without putting the aircraft or crew at further risk.

While monitoring the readings might seem reasonable, it does not address the immediate risk, as continued operation under abnormal conditions can lead to engine failure. Adjusting the throttle may not resolve the underlying cause of the oil pressure fluctuation and could exacerbate the problem. Consulting with a co-pilot could be beneficial for coordination, but it does not substitute for immediate action required to safeguard the engine.
