True or False: If the main oil filter becomes clogged, a filter bypass valve allows unfiltered oil to continue to lubricate the engine?

The statement is true because the design of the oil system in the T-6A includes a filter bypass valve that plays a crucial role in maintaining engine lubrication even in the event of a clogged oil filter. When the oil filter becomes obstructed, this bypass valve automatically opens, allowing oil to flow directly to the engine without passing through the filter. While this means that the oil being used is unfiltered, it ensures that the engine continues to receive lubrication, which is vital to prevent damage and maintain operation until the issue can be addressed. This feature is particularly important in aviation settings where engine reliability is critical.
