## Summary

This document proposes to adopt a new airworthiness directive (AD) that would apply to certain Aerostar Aircraft Corporation (Aerostar) Models 601, 601P, 602P, and 700P airplanes. The proposed AD would require you to replace Roto-Master and Rajay scavenge pumps with Aerostar scavenge pumps. The proposed action is the result of failures of the existing Roto-Master and Rajay scavenge pump found during regular maintenance inspections. The actions specified by this proposed AD are intended to prevent failure of the oil scavenge pumps, which could result in loss of engine oil and possible loss of engine power.
