You are performing an annual inspection on a Cessna 150L with a recently installed McCauley propeller 1A101/PCM. Which statement is correct?

The correct choice is that neither option A nor option B is true when evaluating the applicability of the McCauley propeller model 1A101/PCM to the Cessna 150L.

In context, the McCauley 1A101/PCM propeller is compatible with various aircraft models, not just limited to specific variations such as the A150L. While the Cessna 150L model may utilize this propeller, it's important to note that the propeller is designed for broader applicability within the Cessna 150 series and other compatible aircraft. Therefore, stating that the propeller is applicable exclusively to the A150L (as both options A and B do) is inaccurate.

Understanding the interchangeable nature of propeller models across different aircraft ensures that maintenance professionals can make informed decisions during inspections and replacements, based on type certificates and approved data from manufacturers rather than limited assumptions.
