The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-400, 747-400D, 747-400F, 747-8F, and 747-8 series airplanes. This AD was prompted by reports of very high temperatures, near the floor in the aft lower lobe cargo compartment. This AD requires installing an additional zone temperature sensor (ZTS) assembly in the aft cargo compartment, and, for certain airplanes, installing tape and replacing the markers in the bulk cargo compartment. We are issuing this AD to prevent overheating of the aft lower lobe cargo compartment, where, if temperature sensitive cargo is present, the release of flammable vapors could result in a fire or explosion if exposed to an ignition source.

Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Airplanes
We are superseding Airworthiness Directive (AD) 95-26-11 for all Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model L-1011 series airplanes. AD 95-26-11 required repetitive inspections to detect cracking of the fittings that attach the aft pressure bulkhead to the fuselage stringers, repetitive inspections to detect cracking of the fittings and of the splice tab of the aft pressure bulkhead, and corrective actions if necessary. This new AD requires repetitive inspections to detect cracking of the fittings that attach the aft pressure bulkhead to the fuselage stringers, repetitive inspections to detect cracking of the fittings and of the splice tab of the aft pressure bulkhead, repetitive inspections for cracking of certain aft fuselage skin panels, a structural modification, a post- modification inspection program, and corrective actions if necessary. This AD was prompted by a determination that the fittings at stringer attachments to the upper region of the aft pressure bulkhead are subject to widespread fatigue damage (WFD). We are issuing this AD to prevent simultaneous failure of multiple stringer end fittings through fatigue cracking at the aft pressure bulkhead, which could lead to rapid decompression of the airplane.

The Boeing Company Airplanes
We are superseding Airworthiness Directive (AD) 2007-13-05 for all The Boeing Company Model 777-200, -200LR, -300, and -300ER series airplanes. AD 2007-13-05 required repetitive measurements of the freeplay of the right and left elevators, rudder, and rudder tab, and related investigative and corrective actions if necessary. This new AD requires repetitive freeplay inspections and lubrication of the right and left elevators, rudder, and rudder tab, and related investigative and corrective actions if necessary. This AD was prompted by the manufacturer's determination that the procedure for the rudder freeplay inspection does not properly detect excessive freeplay in the rudder control load loop. We are issuing this AD to detect and correct excessive wear in the load loop components of the control surfaces, which could lead to excessive freeplay of the control surfaces, flutter, and consequent loss of control of the airplane.

The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 747-8F and 747-8 series airplanes. This AD was prompted by reports of delamination damage to leading edge (LE) variable camber krueger (VCK) flaps. This AD requires repetitive inspections to detect delamination damage of the lightning strike applique (LSA) on certain LE VCK flaps, and corrective actions if necessary. We are issuing this AD to detect and correct delamination damage to certain LE VCK flaps, which can reduce the lightning strike protection capability on certain LE VCK flaps and result in an uncommanded motion of the trailing edge flap system; such uncommanded flap motion, without shutdown of the trailing edge or leading edge flaps, could cause unexpected changes in lift, potentially resulting in asymmetric lift and loss of control of the airplane.

Airbus Airplanes
We are adopting a new airworthiness directive (AD) for all Airbus Model A318, A319, A320, and A321 series airplanes. This AD was prompted by a report of corrosion found during the manufacturing process for some oxygen pipe assemblies that are used to supply oxygen to the flightcrew. This AD requires an inspection to determine the batch number or installation date of the oxygen pipe assembly that is installed at the end of the right-hand crew distribution line, and, if necessary, replacement of the pipe. We are issuing this AD to detect and correct corrosion, which could lead to blocked or reduced oxygen supply to a flightcrew member during a decompression event or a smoke/ fire event in the cockpit. Under certain conditions, corrosion particles could increase the risk of fire in the cockpit.

Bombardier, Inc. Airplanes
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-400 series airplanes. This AD was prompted by reports of corrosion in the low-rate discharge tubes of the fire protection system leading to the forward baggage compartment, and perforation of one or more tubes. This AD requires repetitive checks for leakage of the discharge tubes of the fire protection system. This AD also mandates eventual replacement of all existing aluminum tube assemblies with new, improved corrosion-resistant stainless steel tube assemblies. We are issuing this AD to prevent perforation of the low- rate discharge tubes, which could result in insufficient fire extinguishing agent reaching the forward baggage compartment in the event of a fire, which could result in damage to the airplane and injury to the occupants.
