## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all Fokker Model F.28 series airplanes. This proposed AD would require a one-time inspection of the area underneath the auxiliary power unit (APU) enclosure to determine if drain tubes in the area are correctly installed and to detect damaged wiring, and corrective action if necessary. This proposed AD is prompted by a report of a fire under the APU enclosure. We are proposing this AD to prevent fuel from accumulating under the APU enclosure, which, in the presence of an ignition source, could result in a fire.
