Summary
The FAA proposes to adopt a new airworthiness directive (AD) for all Fokker Model F.28 Mark 0100 series airplanes. This proposed AD would require an inspection to determine the part number of the passenger service unit (PSU) panels for the PSU modification status, and corrective actions if applicable. This proposed AD is prompted by reported incidents of smoke in the passenger compartment during flight. One of those incidents also included a burning smell and consequently led to emergency evacuation of the airplane. We are proposing this AD to prevent overheating of the PSU panel due to moisture ingress, which could result in smoke or fire in the passenger cabin.
