Airworthiness Directives; Airbus Airplanes
Document Number: 2012-16970
Type: Proposed Rule
Date: 2012-07-11
Agency: Federal Aviation Administration, Department of Transportation
We are revising an earlier proposed airworthiness directive (AD) for all Airbus Model A318 series airplanes, Airbus Model A319 series airplanes, Airbus Model A320 series airplanes, and Airbus Model A321 series airplanes. That NPRM proposed an inspection to determine if certain angle of attack (AOA) probes are installed, and replacing the affected AOA probe if necessary. That NPRM was prompted by reports of oil residue between the stator and the rotor parts of the position resolvers of the AOA vane, which was a result of incorrect removal of the machining oil during the manufacturing process of the AOA resolvers. This action revises that NPRM by including an inspection to determine if certain other AOA probes are installed, and replacing the affected probes. We are proposing this AD to prevent erroneous AOA information and consequent delayed or non-activation of the AOA protection systems which, during flight at a high angle of attack, could result in reduced control of the airplane. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
Airworthiness Directives; Airbus Airplanes
Document Number: 2012-16966
Type: Proposed Rule
Date: 2012-07-11
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A330-200 freighter series airplanes; Model A330-200 and - 300 series airplanes; and Model A340-200 and -300 series airplanes. This proposed AD was prompted by reports of ram air turbine (RAT) pump failure. This proposed AD would require inspecting the RAT pump anti- stall valve for correct setting, re-identifying the RAT pump, performing a functional ground test of the RAT, and replacing the RAT pump or the RAT assembly with a serviceable part if necessary. We are proposing this AD to detect and correct malfunction of the RAT pump, which could lead to in-flight loss of the RAT-pump pressurization, possibly resulting in reduced control of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2012-16963
Type: Proposed Rule
Date: 2012-07-11
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model DC-10-10 and MD-10-10F airplanes. This proposed AD was prompted by a report that the safe life limit on certain main landing gear (MLG) upper torque link bolts is reduced significantly due to incorrect fabrication. This proposed AD would require replacing certain MLG upper torque link bolts with a new or serviceable part. We are proposing this AD to prevent damage to the MLG and consequent damage to airplane structure, which could adversely affect the airplane's continued safe flight and landing.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2012-16962
Type: Proposed Rule
Date: 2012-07-11
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 747-400, and -400F series airplanes. This proposed AD was prompted by multiple reports of integrated display unit (IDU) malfunctions and mode control panel (MCP) malfunctions. This proposed AD would require installing new software, replacing the duct assembly with a new duct assembly, making wiring changes, and routing certain wire bundles. We are proposing this AD to prevent IDU malfunctions, which could affect the ability of the flight crew to read primary displays for airplane attitude, altitude, or airspeed, and consequently reduce the ability of the flight crew to maintain control of the airplane.
Airworthiness Directives; Bombardier, Inc. Airplanes
Document Number: 2012-16960
Type: Proposed Rule
Date: 2012-07-11
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes, Model CL-600-2D15 (Regional Jet Series 705) airplanes, Model CL-600-2D24 (Regional Jet Series 900) airplanes, and Model CL-600-2E25 (Regional Jet Series 1000) airplanes. This proposed AD was prompted by a report that certain wing-to-fuselage attachment nuts do not conform to the certification design requirements for dual locking features. This proposed AD would require repetitive inspections to determine that cotter pins are installed at affected wing-to- fuselage attachment joints and replacement if necessary. We are proposing this AD to prevent loss of wing-to-fuselage attachment joints, which could result in the loss of the wing.
Proposed Amendment of Class E Airspace; Dillon, MT
Document Number: 2012-16865
Type: Proposed Rule
Date: 2012-07-11
Agency: Federal Aviation Administration, Department of Transportation
The FAA is issuing a SNPRM for the notice of proposed rulemaking (NPRM) published on March 15, 2012, in order to elicit comments addressing the proposed amendment to create Class E surface airspace and further expand the previous proposed amendment of Class E airspace extending upward from 700 feet above the surface at Dillon Airport, Dillon, MT, to accommodate aircraft using new Area Navigation (RNAV) Global Positioning System (GPS) standard instrument approach procedures. The original NPRM only proposed an amendment of Class E airspace extending upward from 700 feet above the surface.
Airworthiness Directives; Pratt & Whitney Division Turbofan Engines
Document Number: 2012-16857
Type: Proposed Rule
Date: 2012-07-11
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all Pratt & Whitney PW4050, PW4052, PW4056, PW4060, PW4060A, PW4060C, PW4062, PW4062A, PW4152, PW4156, PW4156A, PW4158, PW4160, PW4460, PW4462, and PW4650 turbofan engines, including models with any dash number suffix. This proposed AD was prompted by 16 reports of damaged or failed 3rd stage low-pressure turbine (LPT) duct segments. This proposed AD would require removing from service certain part numbers (P/Ns) of 3rd stage LPT duct segments. We are proposing this AD to prevent failure of the 3rd stage LPT duct segments, which could lead to LPT rotor damage, uncontained engine failure, and damage to the airplane.
Airworthiness Directives; Rolls-Royce plc Turbofan Engines
Document Number: 2012-16856
Type: Proposed Rule
Date: 2012-07-11
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all Rolls-Royce plc (RR) RB211-524G2-19; RB211-524G2-T-19; RB211-524G3-19; RB211-524G3-T-19; RB211-524H2-19; RB211-524H2-T-19; RB211-524H-36; RB211-524H-T-36; RB211-535E4-37; RB211-535E4-B-37; RB211-535E4-B-75; and RB211-535E4-C-37 turbofan engines. This proposed AD was prompted by an investigation by RR concluding that certain intermediate-pressure (IP) turbine discs produced before 1997 by a certain supplier may contain steel inclusions. This proposed AD would require removal of the affected IP turbine discs to inspect them for steel inclusions, and removal from service if the discs fail the inspection. This proposed AD would also require removal from service of some IP turbine discs at reduced life limits. We are proposing this AD to prevent uncontained IP turbine disc failure, engine failure, and damage to the airplane.

Document Number: 2012-16021
Type: Rule
Date: 2012-07-11
Agency: Federal Aviation Administration, Department of Transportation
