## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Dornier Model 328-300 series airplanes. This proposal would require replacing the brake assemblies with modified brake assemblies. This action is necessary to prevent overheating of the brakes, which could result in cracked pistons and consequent leakage and burning of the hydraulic fluid. This action is intended to address the identified unsafe condition.
