Airworthiness Directives; Airbus Helicopters
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model EC120B, EC130B4, and EC130T2 helicopters. This AD was prompted by a report of corrosion detected on certain part- numbered landing gear assemblies. This AD requires, for helicopters with certain part-numbered landing gear assemblies installed, visually inspecting for cracks and corrosion; borescope inspecting; and if required, removing corrosion, measuring thickness, interpreting results of the measurements, applying chemical conversion coating and primer, and removing affected parts (landing gear assembly) and affected part sub-assemblies (front or rear crossbeam or left-hand or right-hand skid assembly) from service and replacing with airworthy parts. This AD will allow an affected part or affected part sub-assembly to be installed on a helicopter if certain actions in this AD are accomplished. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Engines
The FAA proposes to supersede five airworthiness directives (ADs) for all Rolls-Royce Deutschland Ltd. & Co KG (RRD) Model RB211- 535E4-37, RB211-535E4-B-37, and RB211-535E4-C-37 engines. The existing ADs require recalculating the cyclic life for certain engine life- limited rotating parts and replacing those parts that have exceeded their cyclic life limit within specified compliance times. Since the FAA issued those ADs the manufacturer has revised the engine time limits manual (TLM), introducing new and more restrictive instructions. This proposed AD would require revising the airworthiness limitations section (ALS) of the existing approved maintenance or inspection program, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 757-200, -200CB, and -200PF series airplanes. This proposed AD was prompted by a report of cracks found at the main deck cargo door forward and aft hinge attachment holes. This proposed AD would require a maintenance records check for repairs at the forward and aft hinge areas of the main deck cargo door cutout; repetitive open-hole high frequency eddy current (HFEC) inspections for cracks in the unrepaired areas of the bear strap, skin, doubler, and upper sill chord at the main deck cargo door forward and aft hinge attachment holes; and corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; The Boeing Company Airplanes
The FAA proposes to supersede Airworthiness Directive (AD) 2019-25-17, which applies to all The Boeing Company Model 737-600, - 700, -700C, -800, -900, and -900ER series airplanes. AD 2019-25-17 requires revising the existing airplane flight manual (AFM) to prohibit selection of certain runways for airplanes equipped with certain software. Since the FAA issued AD 2019-25-17, Boeing has developed new software to address the unsafe condition. This proposed AD would retain the requirements of AD 2019-25-17. This proposed AD would also require installing the new software and performing a software configuration check, which would terminate the AFM revision. The FAA is proposing this AD to address the unsafe condition on these products.
Accepted Means of Compliance; Airworthiness Standards: Transport Category Airplanes
This document announces SAE International (SAE) aerospace standard (AS) for use as a means of compliance to the applicable airworthiness standards for transport category airplanes. The FAA accepts SAE Designation AS6960 ``Performance Standards for Seat Furnishings'', section 3.2.3 as a means of compliance with regard to the design of seat furnishings.
