Standard Instrument Approach Procedures, Weather Takeoff Minimums; Miscellaneous Amendments
This amendment establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) and/or Weather Takeoff Minimums for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, addition of new obstacles, or changes in air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.
Airworthiness Directives; Rolls-Royce plc RB211-524 Series Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) for Rolls Royce plc (RR) RB211-524 series turbofan engines with certain part number (P/N) intermediate pressure (IP) compressor stage 5 disks installed. This AD requires new reduced IP compressor stage 5 disk cyclic limits. This AD also requires removing from service affected disks that already exceed the new reduced cyclic limit, and removing other affected disks before exceeding their cyclic limits, using a drawdown schedule. This AD results from the discovery of cracks in the cooling air hole areas of the disk front spacer arm. We are issuing this AD to prevent IP compressor stage 5 disk failure, which could result in uncontained engine failure and possible damage to the airplane.
Airworthiness Directives; Airbus Model A300 B2 and B4 Series Airplanes; Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model A300 C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes); and Model A310-200 and -300 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Airbus airplane models, as specified above. This AD requires modifying the thermal insulation system of certain fuselage frames, and modifying the fuselage drainage system. This AD also requires revising the FAA-approved maintenance inspection program to include inspections for corrosion or cracking in the subject areas. This AD is prompted by reports of corrosion in the lower part of the pressure bulkhead at certain fuselage frames. We are issuing this AD to prevent accumulation of condensation in the insulation blankets of certain fuselage frames, which could cause corrosion that could result in reduced structural integrity of the fuselage and consequent rapid decompression of the airplane.
Airworthiness Directives; Boeing Model 747-100B SUD, -200B, -300, -400, and -400D Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 747-100B SUD, -200B, -300, -400, and -400D series airplanes. This AD requires repetitive inspections for cracking in fuselage stringers 8L, 8R, 10L, and 10R at body stations 460, 480, and 500 frame locations; and repair if necessary. This AD is prompted by findings of cracking in fuselage stringers 8L, 8R, 10L, and 10R at body stations 460, 480, and 500 frame locations. We are issuing this AD to detect and correct fatigue cracking in certain fuselage stringers, which, if left undetected, could result in fuselage skin cracking that reduces the structural integrity of the skin panel, and consequent rapid depressurization of the airplane.
Airworthiness Directives; McDonnell Douglas Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F (KC-10A and KDC-10), DC-10-40, DC-10-40F, MD-10-10F, MD-10-30F, MD-11, and MD-11F Airplanes
This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-10-10, DC-10-10F, DC- 10-15, DC-10-30, DC-10-30F (KC-10A and KDC-10), DC-10-40, DC-10-40F, MD-10-10F, MD-10-30F, MD-11, and MD-11F airplanes, that requires performing a functional test of the exterior emergency control handle assemblies of the forward passenger doors, and corrective actions, if necessary. This action is necessary to prevent failure of the forward passenger doors to operate properly in an emergency condition, which could delay an emergency evacuation and possibly result in injury to passengers and flightcrew. This action is intended to address the identified unsafe condition.
Airworthiness Directives; Airbus Model A320-111 Airplanes and Model A320-200 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A320-111 airplanes and Model A320-200 series airplanes. This AD requires installing insulator and cable ties to the electrical cables of the S routes at the gaps in the raceway in the wing trailing edge and the wing tip and wing root areas. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent injection of high voltage current into the low voltage wiring that passes through the fuel tanks, which could result in a possible fuel tank explosion.
Airworthiness Directives; BAE Systems (Operations) Limited (Jetstream) Model 4101 Airplanes
The FAA is adopting a new airworthiness directive (AD) for all BAE Systems (Operations) Limited (Jetstream) Model 4101 airplanes. This AD requires repetitive detailed and specialized inspections to detect fatigue damage in the fuselage, replacement of certain bolt assemblies, and corrective actions if necessary. This AD results from a review of primary airframe fatigue test results and a Maintenance Steering Group 3 (MSG-3) analysis. We are issuing this AD to detect and correct fatigue damage of the fuselage, door, engine nacelle, empennage, and wing structures, which could result in reduced structural integrity of the airplane.
Airworthiness Directives; The New Piper Aircraft, Inc. Models PA-34-200T, PA-34-220T, PA-44-180, and PA-44-180T Airplanes
The FAA adopts an airworthiness directive (AD) to supersede AD 2003-11-14, which applies to certain The New Piper Aircraft, Inc. (Piper) Models PA-34-200T, PA-34-220T, PA-44-180, and PA-44-180T airplanes that have a model 91E92-1 or model 91E93-1 combustion heater fuel pump installed. AD 2003-11-14 currently requires you to do a one- time inspection of the combustion heater fuel pumps for fuel leakage. If leakage is found, repair or replace the fuel pump. This AD retains all the actions of AD 2003-11-14 and includes additional serial numbers for the Models PA-34-220T and PA-44-180 airplanes in the applicability section. This AD results from an investigation that concluded that after the issuance of AD 2003-11-14, additional fuel pumps that did not meet the quality control (inspection or design) requirements of the AD had been installed in Models PA-34-220T and PA-44-180 airplanes. We are issuing this AD to correct quality control problems with the heater fuel pump, which could result in failure of the heater fuel pump. Such failure could lead to fire or explosion in the cockpit.
Airworthiness Directives; Bombardier Model CL-600-1A11 (CL-600), Model CL-600-2A12 (CL-601), and Model CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604) Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model CL-600-1A11 (CL-600), Model CL-600-2A12 (CL- 601), and Model CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604) airplanes. This AD requires operators to assign serial numbers or part numbers to certain landing gear parts and to establish the number of landings on the parts, if necessary. This AD also requires operators to revise the Airworthiness Limitations section of the Instructions for Continued Airworthiness to reflect the new life limits of the landing gear parts. This AD is prompted by reports that landing gear parts that have safe-life limits but do not have serial numbers or part numbers can be removed from one landing gear and re-installed on another, making tracking difficult. We are issuing this AD to prevent life-limited landing gear parts from being used beyond their safe-life limits, which could lead to collapse of the landing gear.
