Résumé
The FAA proposes to adopt a new airworthiness directive (AD) for certain EMBRAER Model EMB-120, -120ER, -120FC, -120QC, and -120RT airplanes. This proposed AD would require installing a rivet and washer in the hole of the upper frame of the auxiliary power unit (APU) firewall. This proposed AD results from a report indicating that, during production, a pinhole was left open at the upper frame of the APU firewall. We are proposing this AD to ensure that the APU compartment is isolated from the rest of the airplane in the event of an APU fire.
