## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to all Fokker Model F.28 Mark 1000, 2000, 3000, and 4000 series airplanes. This proposal would require repetitive inspections for discrepancies of the internal fuselage skin panels located in the stub wing areas; and corrective action if necessary. This action is necessary to detect and correct heat damage to the fuselage skin panels caused by the leakage of hot air from one of the bleed air ducts inside the stub wing, which could result in reduced structural integrity of the engine support structure. This action is intended to address the identified unsafe condition.
