Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2013-24121
Type: Proposed Rule
Date: 2013-10-02
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-200, -200C, -300, -400, and -500 series airplanes. This proposed AD was prompted by reports of cracking found in the skin at the lower aft corner of the forward entry doorway on airplanes that do not have an airstair door cutout. This proposed AD would require repetitive inspections for cracking in the lower corners of the forward entry doorway on airplanes that do not have an airstair door cutout, and repair if necessary. We are proposing this AD to detect and correct cracking in the lower corners of the forward entry doorway, which could lead to crack progression and consequent rapid decompression of the airplane.
Airworthiness Directives; Bombardier Inc., Airplanes
Document Number: 2013-24077
Type: Proposed Rule
Date: 2013-10-02
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-102, -103, -106, -201, -202, -301, -311, and -315 airplanes. This proposed AD results from fuel system reviews conducted by the manufacturer. This proposed AD would require accomplishing modifications to the fuel system. We are proposing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
Airworthiness Directives; Airbus Airplanes
Document Number: 2013-24058
Type: Proposed Rule
Date: 2013-10-02
Agency: Federal Aviation Administration, Department of Transportation
We are revising an earlier proposed airworthiness directive (AD) for all Airbus Model A330-200, -300 and -200 Freighter series airplanes, and Model A340-200, -300, -500, and -600 series airplanes. The NPRM proposed to require, for certain airplanes, revising the airplane flight manual (AFM) to advise the flight crew of emergency procedures for addressing Angle of Attack (AOA) sensor blockage. The NPRM also proposed to mandate replacing the AOA sensor conic plates with AOA sensor flat plates, which is a terminating action for the AFM revision. The NPRM was prompted by a report that an airplane equipped with AOA sensors installed with conic plates recently experienced blockage of all sensors during climb, leading to autopilot disconnection and activation of the alpha protection (Alpha Prot) when Mach number was increased. For certain airplanes, this action revises the NPRM by adding a modification of the installation of certain AOA sensor flat plates. We are proposing this AD to prevent 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; The Boeing Company Airplanes
Document Number: 2013-24040
Type: Proposed Rule
Date: 2013-10-02
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede airworthiness directive (AD) 2005-07- 12 that applies to certain The Boeing Company Model 737-100, -200, - 200C, -300, -400, and -500 series airplanes. AD 2005-07-12 requires detailed and eddy current inspections to detect cracking of the frame web around the cutout for the doorstop intercostal strap at the aft side of the station (STA) 291.5 frame at stringer 16R, and corrective action if necessary. Since we issued AD 2005-07-12, we received reports of new findings of cracking at various locations of the STA 277 to STA 291.5 frames and intercostals, including webs, chords, clips, and shear ties, between stringers 7R and 17R. This proposed AD would add new inspections for cracking at the forward galley door cutout, and corrective actions if necessary. This proposed AD would also reduce a certain inspection threshold required by AD 2005-07-12. We are proposing this AD to detect and correct fatigue cracking of the aft frame and frame support structure of the forward galley door, which could result in a severed fuselage frame web, rapid decompression of the airplane, and possible loss of the forward galley door.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2013-24034
Type: Rule
Date: 2013-10-02
Agency: Federal Aviation Administration, Department of Transportation
We are superseding airworthiness directive (AD) 2004-18-06 for certain The Boeing Company Model 737-200, -200C, -300, -400, and -500 series airplanes. AD 2004-18-06 required repetitive inspections to find fatigue cracking of certain upper and lower skin panels of the fuselage, and follow-on and corrective actions if necessary. AD 2004- 18-06 also included a terminating action for the repetitive inspections of certain modified or repaired areas only. This new AD adds new inspections for cracking of the fuselage skin along certain chem-milled lines, and corrective actions if necessary. This new AD also reduces certain thresholds and intervals required by AD 2004-18-06. This AD was prompted by new findings of vertical cracks along chem-milled steps adjacent to the butt joints. We are issuing this AD to detect and correct fatigue cracking of the skin panels, which could result in sudden fracture and failure of the skin panels of the fuselage, and consequent rapid decompression of the airplane.
Airworthiness Directives; The Boeing Company Airplanes

Type: Rule
Date: 2013-10-02
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-300, 747-400, 747-400D, and 747SP series airplanes. This AD was prompted by reports of worn or incorrectly assembled latches on main deck escape slides installed on airplane doors. This AD requires determining if the latches are correctly assembled; and doing corrective actions if necessary. This AD also requires, for certain airplanes, modifications to the escape slide/rafts and escape slides. We are issuing this AD to prevent a latch hook moving from closed to open in an escape slide/raft or escape slide, which could result in the escape slide/raft or escape slide not deploying correctly in an emergency, or releasing/inflating into the passenger cabin and causing injury to passengers and crew.

Airworthiness Directives; Sikorsky Aircraft Corporation Helicopters
Document Number: 2013-23439
Type: Rule
Date: 2013-10-02
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for Sikorsky Aircraft Corporation (Sikorsky) Model S-92A helicopters to require modifying the No. 1 engine forward firewall center fire extinguisher discharge tube (No. 1 engine tube) and inspecting the outboard discharge tube to determine if it is correctly positioned. This AD was prompted by the discovery that the No. 1 engine tube installed on the helicopters is too long to ensure that a fire could be effectively extinguished in the helicopter. The actions are intended to ensure the No. 1 engine tube allows for complete coverage of an extinguishing agent in the No. 1 engine compartment area, ensure that a fire would be extinguished and prevent the loss of helicopter control.
Airworthiness Directives; Rolls-Royce plc Turbofan Engines
