✈️FAA Issues Correction for Boeing 737 Airworthiness Directive

The FAA is correcting an airworthiness directive (AD) that was published in the Federal Register. That AD applies to all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. As published, the service information referenced in certain paragraphs of the regulatory text is incorrect, and the dates specified in the "System Airworthiness Limitation No. 3--Fan Blade Out Conditions" text and "System Airworthiness Limitation No. 4--Engine Nacelle Maintenance Errors" text of figure 1 to paragraph (j) of the regulatory text are incorrect. This document corrects those errors. In all other respects, the original document remains the same.

✈️New Airworthiness Directive for Boeing 777

The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 777-200, -200LR, -300, -300ER, and 777F series airplanes. This AD was prompted by a report of a 5-inch crack on the upper wing skin at a certain wing station of the right wing. This AD requires repetitive inspections for cracking of the upper wing skin common to certain fasteners and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.

✈️New Airworthiness Directive for Boeing 737-800

The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-800 series airplanes. This AD was prompted by a determination that the compliance time for the initial ultrasonic inspection required by AD 2019-11-06 is insufficient for certain airplanes. This AD requires reducing the compliance time for the ultrasonic inspection of the skin under the drag link assembly. The FAA is issuing this AD to address the unsafe condition on these products.

✈️Proposed Airworthiness Directive for Boeing 787 Airplanes

The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This proposed AD was prompted by reports of multiple nonconformances, including excessive gaps and pull-up, found during the assembly and installation of the forward pressure bulkhead. This proposed AD would require an internal and external detailed inspection (DET) of the forward pressure bulkhead (FPB) for any damage and performing applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.

✈️New Airworthiness Directives for Boeing 737 Series Airplanes

The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This AD was prompted by two engine fan blade-out (FBO) events that resulted in the separation of engine inlet cowl and fan cowl parts from the airplane. In one event, fan cowl parts damaged the fuselage, which caused loss of pressurization and subsequent emergency descent. This AD requires replacing specified inlet cowl aft bulkhead fasteners for certain airplanes; for certain other airplanes, inspecting the inlet cowl aft bulkhead fastener and replacing the fasteners if rivets are found, and, for all airplanes, replacement of the crushable spacers used in the attachment of the inlet cowl to the engine fan case; or as an option, installing a serviceable inlet cowl. This AD also requires revising the existing maintenance or inspection program, as applicable, to incorporate new airworthiness limitations (AWLs). The FAA is issuing this AD to address the unsafe condition on these products.

✈️Boeing 737 Airworthiness Directive Requires Compliance Updates

The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This AD was prompted by two engine fan blade-out (FBO) events that resulted in the separation of engine inlet cowl and fan cowl parts from the airplane. In one event, fan cowl parts damaged the fuselage, which caused loss of pressurization and subsequent emergency descent. This AD requires replacing the fasteners on the fan cowl support beam hinge fittings for certain airplanes and, for all airplanes, requires modifying the radial restraint assembly and installing an external doubler at the starter vent, or as an option, installing a serviceable fan cowl. This AD also requires revising the existing maintenance or inspection program, as applicable, to incorporate new airworthiness limitations. The FAA is issuing this AD to address the unsafe condition on these products.

✈️New FAA Airworthiness Directive for Boeing 737 Models

The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This AD was prompted by two engine fan blade- out (FBO) events that resulted in the separation of engine inlet cowl and fan cowl parts from the airplane damaging the fuselage, which caused loss of pressurization and subsequent emergency descent. The FBO events also resulted in cracks in the primary exhaust nozzle, potentially resulting in the departure of the primary exhaust nozzle and damaging a stabilizer or striking the fuselage and window. This AD requires an inspection or maintenance records check to determine if the primary exhaust nozzle has an affected part number and, for affected primary exhaust nozzles, an installation of bridge brackets onto the primary exhaust nozzle, or as an option, an installation of a serviceable primary exhaust nozzle. This AD also requires revising the existing maintenance or inspection program, as applicable, to incorporate new airworthiness limitations. The FAA is issuing this AD to address the unsafe condition on these products.

✈️Proposed Airworthiness Directive for Boeing 787 Airplanes

The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This proposed AD was prompted by reports that very high frequency (VHF) radio frequencies transfer between the active and standby windows of the tuning control panel (TCP) without flightcrew input. The uncommanded frequency changes could result in missed communications between the flightcrew and Air Traffic Control. This proposed AD would require updating the TCP operational software (OPS) and performing a software configuration check. The FAA is proposing this AD to address the unsafe condition on these products.

✈️New Airworthiness Directive Impacting Boeing 747 Aircraft Operators

The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-400, 747-400F, 747-8F, and 747-8 series airplanes. This AD was prompted by a report that, during potable water servicing, there were multiple engine indicating and crew alerting system messages. The cause was the separation of a fitting and steel water supply tube above an electronics equipment cooling air filter, behind the forward cargo compartment left sidewall. This AD requires, depending on configuration, installing at certain locations: conduits on exposed potable water supply lines, envelope assemblies over all exposed potable water line fittings and exposed potable water supply lines, a slitted spray shield, a two-piece deflector shield around the equipment cooling system (ECS) air inlet, and/or a shroud on exposed potable water supply lines. The FAA is issuing this AD to address the unsafe condition on these products.

✈️Proposed Airworthiness Directive for Boeing 757 Compliance Requirements

The FAA proposes to supersede Airworthiness Directive (AD) 2019-12-13, which applies to all The Boeing Company Model 757 airplanes. AD 2019-12-13 requires repetitive checks of the aileron trim actuator bearing for free rotation, repetitive detailed inspections of the aileron trim actuator attachment lug for damage and cracking, and applicable on-condition actions. Since the FAA issued AD 2019-12-13, the FAA has determined that a modification must be done to address the unsafe condition. This proposed AD would continue to require the actions in AD 2019-12-13. This proposed AD would also require for certain airplanes changing the lateral control box support assembly and installing an aileron trim actuator bracket, and for certain other airplanes replacing the existing actuator lateral control fitting with an aileron trim actuator bracket, which terminates the repetitive checks and inspections. The FAA is proposing this AD to address the unsafe condition on these products.
