Airworthiness Directives; British Aerospace (Operations) Limited and British Aerospace Regional Aircraft Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all British Aerospace (Operations) Limited Model Jetstream Model 3101 and British Aerospace Regional Aircraft Model Jetstream Model 3201 airplanes. This proposed AD was prompted by mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI identifies the unsafe condition as stress corrosion cracking of the primary flight control cable terminals. This proposed AD would require repetitively inspecting the turnbuckle type control cable terminals in the rudder and elevator primary flight control circuits for corrosion, pitting, and cracking and, depending on the inspection results, replacing an affected cable assembly. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Viking Air Limited (Type Certificate Previously Held by Bombardier Inc. and de Havilland, Inc.) Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Viking Air Limited (type certificate previously held by Bombardier Inc. and de Havilland, Inc.) Model DHC-6-1, DHC-6-100, DHC- 6-200, DHC-6-300, and DHC-6-400 airplanes. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI identifies the unsafe condition as binding of the rod end bearing connecting the lower fuel control unit (FCU) push rod assembly to the FCU power lever. This proposed AD would require performing tests, inspections, and lubrication of the FCU push rod assemblies, and replacing them with improved parts as necessary. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Bell Textron Canada Limited (Type Certificate Previously Held by Bell Helicopter Textron Canada Limited) Helicopters
The FAA is superseding Airworthiness Directive (AD) 2020-20- 06, which applied to certain Bell Helicopter Textron Canada Limited (now Bell Textron Canada Limited) Model 429 helicopters. AD 2020-20-06 required repetitive inspections of certain cyclic and collective assembly bearings. This AD was prompted by new bellcrank assemblies, which have been upgraded with corrosion resistant steel bearings. This AD retains certain requirements of AD 2020-20-06, and depending on the inspection results, requires removing certain parts from service and installing the upgraded cyclic and collective bellcrank assemblies. This AD also requires installing the upgraded collective and cyclic bellcrank assemblies on certain helicopters if not already installed, and prohibits installing certain bellcrank assemblies. The FAA is issuing this AD to address the unsafe condition on these products.
Modification of Class D and Class E Airspace, and Establishment of Class E Airspace; Southwest Oregon Regional Airport, OR; Correction
The FAA is correcting a final rule that appeared in the Federal Register on March 3, 2022. The rule modified the Class D and Class E surface airspace, established Class E airspace designated as an extension to Class D & E surface areas, Class E airspace beginning at 700 feet above the surface, removed navigational aids (NAVAIDs) from text headers, and made administrative changes to the legal descriptions at Southwest Oregon Regional Airport, North Bend, OR. The Final Rule did not explain the purposeful removal of Class E airspace beginning at 1,200 feet above the surface, nor did it properly exclude the Sunnyhill Airport cut-out. This action adds verbiage explaining the removal of Class E airspace beginning at 1,200 feet above the surface, and corrects the legal description for the newly established Class E airspace designated as an extension to Class D & E surface areas to properly exclude Sunnyhill Airport, OR.
Airworthiness Directives; Airbus SAS Airplanes
The FAA is superseding Airworthiness Directive (AD) 2013-25- 11, which applied to all Airbus SAS Model A318-111, -112, -121, and - 122 airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; Model A320-111, -211, -212, -214, -231, -232, and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. AD 2013-25-11 required repetitive inspections of the 80VU rack lower lateral fittings, upper fittings, and shelves for damage, repetitive inspections of the 80VU rack lower central support for cracking, and corrective action if necessary. AD 2013-25-11 also specified optional terminating action for the repetitive inspections. Since the FAA issued AD 2013-25-11, new damage occurrences have been reported, and a different compliance time has been determined for certain inspections, depending on airplane configuration. This AD expands the applicability, removes the optional terminating action, and requires new repetitive inspections; as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Leonardo S.p.a. Helicopters
The FAA proposes to adopt a new airworthiness directive (AD) for certain Leonardo S.p.a. Model A109S and AW109SP helicopters. This proposed AD was prompted by a report of a protective sheath, installed around a fixed flight control rod, which should have been removed during assembly. This proposed AD would require borescope inspecting certain parts, and removing any foreign object if detected, 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.
