## Summary

This document proposes to adopt a new airworthiness directive (AD) that would apply to certain Aeromot-Industria Mecanico Metalurgica Ltda. (Aeromot) Model AMT-200 powered gliders. The proposed AD would require replacing certain flexible hoses in the engine oil system with flexible hoses with a larger internal diameter. The proposed AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Brazil. The actions specified by the proposed AD are intended to prevent inefficiency of the engine lubricating system because of ineffective flexible hoses, which could result in an in-flight engine shutdown with consequent loss of powered glider controllability.
