## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Fokker Model F.28 Mark 1000, 2000, 3000, and 4000 series airplanes. This proposal would require repetitive general visual inspections, lubrication, and tests of the release mechanism for the service/emergency door; and corrective actions if necessary. This proposal also provides an optional terminating action for the repetitive inspections and lubrication. This action is necessary to prevent failure of the release mechanism on the service/emergency door, which could result in the inability to open the service/emergency door during an emergency evacuation. This action is intended to address the identified unsafe condition.
