Airworthiness Directives; Airbus Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes); and Model A310-200 and A310-300 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A300-600, A310-200, and A310-300 series airplanes. This AD requires modifying the forward outflow valve of the pressure regulation subsystem. This AD results from a report of accidents resulting in injuries occurring on in-service airplanes when crewmembers forcibly initiated opening of passenger/crew doors against residual pressure, causing the doors to rapidly open. In these accidents, the buildup of residual pressure in the cabin was caused by the blockage of the outflow valve by an insulation blanket. We are issuing this AD to prevent an insulation blanket or other debris from being ingested into and jamming the forward outflow valve of the pressure regulation subsystem, which could lead to the inability to control cabin pressurization and adversely affect continued safe flight of the airplane.
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; Honeywell RCZ-833J/K, -851J/K, and -854J Communication (COM) Units, Equipped With XS-852E/F Mode S Transponders; and Honeywell XS-856A/B and -857A Mode S Transponders; Installed on But Not Limited to Certain Transport Category Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Honeywell COM units and transponders, installed on but not limited to certain transport category airplanes. This proposed AD would require a revision to the Normal Procedures section of the Airplane Flight Manual to advise the flightcrew to check the status of the transponder after changing the air traffic control (ATC) code. This proposed AD would also require replacing certain identification plate(s) with new plate(s), testing certain COM units or transponders as applicable, and corrective action if necessary. For certain airplanes, this proposed AD would require replacing the transponders of certain COM units with new or modified transponders. For certain other airplanes, this proposed AD would require installing a modification into certain transponders. This proposed AD results from the transponder erroneously going into standby mode if the flightcrew takes longer than five seconds when using the rotary knob of the radio management unit to change the ATC code. We are proposing this AD to prevent the transponder of the COM unit from going into standby mode, which could increase the workload on the flightcrew and result in improper functioning of the traffic alert and collision avoidance system.
Airworthiness Directives; Goodyear Aviation Tires, Part Number 217K22-1, Installed on Various Transport Category Airplanes, Including But Not Limited to Bombardier Model BD-700-1A10 and BD-700-1A11 Airplanes; and Gulfstream Model G-1159, G-1159A, G-1159B, G-IV, GIV-X, GV, and GV-SP Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain aviation tires installed on various transport category airplanes. This proposed AD would require a one-time inspection of the nosewheel tires to determine if they are within a designated serial number range, and replacement if necessary. This proposed AD results from reports of tread separations and tread-area bulges on the nosewheel tires. We are proposing this AD to prevent tread separation from a nosewheel tire during takeoff or landing, which could result in compromised nosewheel steering or ingestion of separated tread by an engine, and consequent reduced controllability of the airplane on the runway or in the air.
Airworthiness Directives; Eurocopter France Model SA-365 N1, AS-365 N2, N3, SA 366 G1, and EC-155B and B1 Helicopters
This amendment adopts a new airworthiness directive (AD) for the specified Eurocopter France (Eurocopter) Model SA-365 N1, AS-365 N2, N3, SA 366 G1, and EC-155B and B1 helicopters. This action requires a one-time inspection for end play in the pitch control rod assembly double bearing (bearing) using the tail rotor (T/R) hub control plate, and before further flight, replacing the bearing if end play is present. This amendment is prompted by one incident in which a pilot lost T/R pitch control of a helicopter while landing. The actions specified in this AD are intended to detect damage to the bearing, resulting in end play and prevent loss of T/R pitch control and subsequent loss of control of the helicopter.
Standard Instrument Approach Procedures; Miscellaneous Amendments
This amendment amends Standard Instrument Approach Procedures (SIAPs) for operations at certain airports. These regulatory actions are needed 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; Boeing Model 767 Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Boeing Model 767 airplanes. This AD requires repetitive inspections for cracking in the skin, the bulkhead outer chord, and the strap of the bulkhead outer chord at station (STA) 1725.5; and repair if necessary. This AD also provides for repairs, which are optional for airplanes on which no cracking is found, that terminate certain inspections. This AD results from reports of cracking in the skin panel common to stringer 7R and aft of the STA 1725.5 butt splice, and in the strap of the bulkhead outer chord at STA 1725.5. We are issuing this AD to detect and correct cracking in the skin, the bulkhead outer chord, or the strap of the bulkhead outer chord in this area, which could progress into surrounding areas and result in reduced structural integrity of the support structure for the vertical or horizontal stabilizer and subsequent loss of control of the airplane.
Airworthiness Directives; Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-300, 747-400, 747-400D, and 747SR Series Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Boeing Model 747-100, -200, and -300 series airplanes. That AD currently requires repetitive inspections to detect cracking of certain lower lobe fuselage frames, and repair if necessary. This new AD retains all the requirements of the existing AD, and adds airplanes to the applicability. This AD results from reports indicating that fatigue cracks were found in lower lobe frames on the left side of the fuselage. We are issuing this AD to detect and correct fatigue cracking of certain lower lobe fuselage frames, which could lead to fatigue cracks in the fuselage skin, and consequent rapid decompression of the airplane.
Airworthiness Directives; Dassault Model Falcon 900EX Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Dassault Model Falcon 900EX airplanes. This AD requires inspecting the number 2 engine left- and right-hand forward mounts for missing rivets, and installing rivets if necessary. This AD results from reports of two missing rivets in the front section of the central engine mast discovered on airplanes in service and in production. We are issuing this AD to detect and correct missing rivets in the front section of the central engine mast, which could result in reduced structural integrity of the central engine mast, possible separation of the engine from the airplane during flight, and consequent loss of control of the airplane.
Airworthiness Directives; Airbus Model A310-200 and -300 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Airbus Model A310-200 and -300 series airplanes. This AD requires doing repetitive rotating probe inspections for any crack of the rear spar internal angle and the left and right sides of the tee fitting, and doing related investigative/corrective actions if necessary. This AD also requires modifying the holes in the internal angle and tee fitting by cold expansion. This AD results from full-scale fatigue tests, which revealed cracks in the lower rear spar internal angle, and tee fitting. We are issuing this AD to detect and correct fatigue cracks of the rear spar internal angle and tee fitting, which could lead to the rupture of the internal angle, tee fitting, and rear spar, and consequent reduced structural integrity of the wings.
Airworthiness Directives; Airbus Model A330-200, A330-300, A340-200, and A340-300 Series Airplanes; and A340-541 and A340-642 Airplanes
The FAA is adopting a new airworthiness directive (AD) for all Airbus Model A330-200, A330-300, A340-200, and A340-300 series airplanes; and A340-541 and A340-642 airplanes. This AD requires operators to revise the Airworthiness Limitations section of the Instructions for Continued Airworthiness to incorporate new information. This information includes, for all affected airplanes, decreased life limit values for certain components; and for Model A330- 200 and -300 series airplanes, new inspections, compliance times, and new repetitive intervals to detect fatigue cracking, accidental damage, or corrosion in certain structures. This AD results from a revision to subsection 9-1 of the Airbus A330 and A340 Maintenance Planning Documents (MPD) for Life limits/Monitored parts, and subsection 9-2 of the Airbus A330 MPD for Airworthiness Limitations Items. We are issuing this AD to prevent fatigue cracking, damage, or corrosion, which could result in reduced structural integrity of these airplanes.
Airworthiness Directives; Cirrus Design Corporation Models SR20 and SR22 Airplanes
We propose to supersede Airworthiness Directive (AD) 2005-17- 19, which applies to certain Cirrus Design Corporation (CDC) Models SR20 and SR22 airplanes. AD 2005-17-19 currently requires you to measure and adjust the crew seat break-over bolts and to replace the crew seat recline locks on both crew seats. Since we issued AD 2005-17- 19, CDC developed new crew seat break-over pins to replace the old crew seat break-over bolts. Consequently, this proposed AD would retain the action from AD 2005-17-19 of replacing the crew seat recline locks on both seats and would add the action of replacing the crew seat break- over bolts with the new crew seat break-over pins on both seats. We are proposing this AD to prevent the crew seats from folding forward during emergency landing dynamic loads with consequent occupant injury.
Airworthiness Directives; Eurocopter Canada Limited Model BO 105 LS A-3 Helicopters
This document proposes adopting a new airworthiness directive (AD) for Eurocopter Canada Limited (Eurocopter) Model BO 105 LS A-3 helicopters. This proposal would require replacing certain fixed bolts and nuts, reidentifying certain main rotor nuts, and revising the Airworthiness LimitationsTime Change Items (TCI) list to reflect the new life limits and new part numbers. This proposal is prompted by a re-evaluation of certain fatigue-critical parts, which resulted in establishing new life limits for certain like-numbered parts and reidentifying a certain existing part with a different part number, or in some cases, replacing them with new parts. The actions specified by this proposed AD are intended to prevent fatigue failure of the fixed bolts and nuts, and subsequent loss of control of the helicopter.
Airworthiness Directives; Sikorsky Aircraft Corporation Model S-76A, B, and C Helicopters
This document proposes adopting a new airworthiness directive (AD) for Sikorsky Aircraft Corporation (Sikorsky) Model S-76A, B, and C helicopters. The AD would require inspecting all installed HR Textron main rotor servo actuators (servo actuators) for a high rate of leakage and also inspecting for contaminated hydraulic fluid. The AD would also require reducing the time-in-service (TIS) interval for overhauling the servo actuators. This proposal is prompted by a National Transportation Safety Board (NTSB) Safety Recommendation written in response to an accident involving a Model S-76 helicopter in which the performance of an HR Textron servo actuator was questioned as a result of piston head seal leakage and piston head plasma spray flaking. The actions specified by the proposed AD are intended to detect a high rate of leaking from a servo actuator and contamination of the hydraulic fluid, which could lead to degraded ability to maneuver the cyclic and collective controls and could result in subsequent loss of control of the helicopter.
Airworthiness Directives; Air Tractor, Inc. Models AT-602, AT-802, and AT-802A Airplanes
We propose to adopt a new airworthiness directive (AD) for all Air Tractor, Inc. Models AT-602, AT-802, and AT-802A airplanes. This proposed AD would require you to repetitively inspect the engine mount for any cracks, repair or replace any cracked engine mount, and report any cracks found to the FAA. This proposed AD results from reports of cracked engine mounts. We are proposing this AD to detect and correct cracks in the engine mount, which could result in failure of the engine mount. Such failure could lead to separation of the engine from the airplane.
Airworthiness Directives; Eurocopter France Model AS-365N2, AS 365 N3, EC 155B, EC155B1, SA-365N, N1, and SA-366G1 Helicopters
This document proposes to revise an existing airworthiness directive (AD) for Eurocopter France (Eurocopter) Model AS-365N2, AS 365 N3, EC 155B, EC155B1, SA-365N, N1, and SA-366G1 helicopters. That AD currently requires inspecting the main gearbox (MGB) base plate for a crack and replacing the MGB if a crack is found. This action would increase the time intervals for inspecting the MGB base plate. This action would also include minor editorial changes throughout the AD. This proposal is prompted by crack growth tests that indicate that the inspection intervals can be increased without affecting safety. The actions specified by the proposed AD are intended to detect a crack in an MGB base plate and prevent failure of one of the MGB attachment points to the frame, which could result in severe vibration and subsequent loss of control of the helicopter.
Airworthiness Directives; Bombardier Model DHC-8-102, -103, -106, -201, -202, -301, -311, and -315 Airplanes
The FAA is revising an existing airworthiness directive (AD) that applies to certain Bombardier Model DHC-8-102, -103, -106, -201, - 202, -301, -311, and -315 airplanes. That AD currently requires performing a one-time inspection to detect chafing of electrical wires in the cable trough below the cabin floor; repairing, if necessary; installing additional tie-mounts and tie-wraps; applying sealant to rivet heads; and modifying electrical wires in certain sections. We issued that AD to prevent chafing of electrical wires. This new AD, for certain airplanes, eliminates the requirement to modify electrical wires in certain sections. This AD results from a report indicating that the modification of electrical wires does not need to be done on certain airplanes subject to the existing AD. We are issuing this AD to prevent chafing of electrical wires, which could result in an uncommanded shutdown of an engine during flight.
Airworthiness Directives; McDonnell Douglas Model DC-9-14, DC-9-15, and -15F Airplanes; Model DC-9-21 Airplanes; Model DC-9-30 Series Airplanes; Model DC-9-41 Airplanes; and Model DC-9-51 Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain McDonnell Douglas Model DC-9-10, DC-9-20, DC-9-30, DC-9-40, and DC-9-50 series airplanes. The existing AD currently requires a one-time inspection at a certain disconnect panel in the left forward cargo compartment to find contamination of electrical connectors and to determine if a dripshield is installed over the disconnect panel, and corrective actions if necessary. This proposed AD would revise the applicability of the existing AD to remove certain airplanes and add others. This proposed AD results from a report of electrical arcing that resulted in a fire. We are proposing this AD to prevent contamination of certain electrical connectors, which could cause electrical arcing and consequent fire on the airplane.
