Federal Aviation Administration October 21, 2005 – Federal Register Recent Federal Regulation Documents

The FAA proposes to adopt a new airworthiness directive (AD) for certain Fokker Model F.28 Mark 0070 and 0100 airplanes. This proposed AD would require modifying the passenger door and installing new placards. This proposed AD results from reports of the airstairs- type passenger door opening during flight. We are proposing this AD to prevent rapid decompression of the airplane, or ejection of a passenger or crew member out the door during flight.

The FAA is superseding an existing airworthiness directive (AD) for Rolls-Royce Deutschland Ltd & Co KG (RRD) (formerly Rolls- Royce Deutschland GmbH, formerly BMW Rolls-Royce GmbH) models BR700- 710A1-10 and BR700-710A2-20 turbofan engines. That AD currently requires initial and repetitive visual and ultrasonic inspections of fan discs, part numbers (P/Ns) BRR18803, BRR19248, and BRR20791 for cracks, and if necessary, replacement with serviceable parts. This ad requires those same inspections for discs having old design P/N fan blades installed, and, extends the inspection interval for fan discs having new design P/N fan blades installed. Also, this AD adds as optional terminating action to the inspections, installation of certain P/N new fan discs, certain P/N new fan blades, and engine fan speed (N1) Keep Out Zone software. This AD results from a revised RRD service bulletin (SB) that introduces relaxed inspection intervals for certain P/N combinations of fan discs and fan blades, and introduces improved design fan discs and fan blades.
