Airworthiness Directives; McDonnell Douglas Model DC-9-10 Series Airplanes; DC-9-20 Series Airplanes; DC-9-30 Series Airplanes; DC-9-40 Series Airplanes; and DC-9-50 Series Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain McDonnell Douglas transport category airplanes. The existing AD requires, among other things, revision of an existing program of structural inspections. This proposed AD would require the implementation of a program of structural inspections of baseline structure to detect and correct fatigue cracking in order to ensure the continued airworthiness of these airplanes as they approach the manufacturer's original fatigue design life goal. This proposed AD is prompted by a significant number of these airplanes approaching or exceeding the design service goal on which the initial type certification approval was predicated. We are proposing this AD to detect and correct fatigue cracking that could compromise the structural integrity of these airplanes.
Airworthiness Directives; Boeing Model 767-200 and -300 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 767-200 and -300 series airplanes. For certain airplanes, this proposed AD would require repetitive inspections for discrepancies of the tube assemblies and insulation of the metered fire extinguisher system and the bleed air duct couplings of the auxiliary power unit (APU) located in the aft cargo compartment; and corrective actions if necessary. For certain other airplanes, this proposed AD would require a one-time inspection for sufficient clearance between the fire extinguishing tube and the APU bleed air duct in the aft cargo compartment, and modification if necessary. This proposed AD is prompted by one report indicating that an operator found a hole in the discharge tube assembly for the metered fire extinguishing system; and another report indicating that an operator found chafing of the fire extinguishing tube against the APU duct that resulted in a crack in the tube. We are proposing this AD to prevent fire extinguishing agent from leaking out of the tube assembly in the aft cargo compartment which, in the event of a fire in the aft cargo compartment, could result in an insufficient concentration of fire extinguishing agent, and consequent inability of the fire extinguishing system to suppress the fire.
Airworthiness Directives; Rolls-Royce plc Models RB211 Trent 768-60, Trent 772-60, and Trent 772B-60 Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) for Rolls-Royce plc (RR) models RB211 Trent 768-60, Trent 772-60, and Trent 772B-60 turbofan engines. This AD requires removal of certain Engine Electronic Controller (EEC) part numbers from service. This AD results from nine reports of loss of engine parameters displayed in the airplane cockpit, with the simultaneous loss of capability to change thrust of the affected engine. We are issuing this AD to prevent loss of airplane control after an aborted takeoff due to asymmetric thrust.
Reservation System for Unscheduled Arrivals at Chicago's O'Hare International Airport
The FAA is adopting a reservation system to limit the number of unscheduled aircraft arrivals at Chicago's O'Hare International Airport (O'Hare) during the peak hours of 7 a.m. through 8:59 p.m., central time, Monday through Friday, and 12 p.m. through 8:59 p.m. central time on Sunday. This Special Federal Aviation Regulation (SFAR) is effective through October 28, 2005. This action is consistent with other FAA actions regarding scheduled arrivals at O'Hare, which combined together effectively reduce congestion and delays at the airport.
