Proposed Amendment of Class E Airspace; Malden, MO
This action proposes to amend Class E airspace extending upward from 700 feet above the surface at Malden Regional Airport, (formerly Malden Municipal Airport), Malden, MO. The FAA is proposing this action as a result of an airspace review caused by the decommissioning of the Malden Very High Frequency Omnidirectional Range (VOR) collocated with Tactical Air Navigation (TACAN) (VORTAC) navigation aid as part of the VOR Minimum Operational Network (MON) Program. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) in the area.
Airworthiness Directives; Bell Textron Canada Limited (Type Certificate Previously Held by Bell Helicopter Textron Canada Limited) Helicopters
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bell Textron Canada Limited (Bell) Model 429 helicopters. This proposed AD was prompted by reports of tail rotor gearbox assemblies found loose on the gearbox support. This proposed AD would require repetitive torque checks of the tail rotor gearbox attachment hardware, and corrective action if necessary. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Viking Aircraft Limited Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Viking Air Limited Model DHC-3 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 fatigue damage of the wing strut lug fitting components and the fuselage to wing strut attachment (tie-bar). This proposed AD would require determining service life limits for the wing strut fitting on the main spar and for the tie-bar and following instructions for removal and replacement of affected parts. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Pacific Aerospace Limited Airplanes
The FAA is withdrawing a notice of proposed rulemaking (NPRM) that proposed to supersede airworthiness directive (AD) AD 2015-23-03 for Pacific Aerospace Limited Model 750XL airplanes. The NPRM was prompted by mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as fatigue cracks on the fin forward pickup plates. Since issuance of the NPRM, the FAA has determined that the actions required by AD 2015-23-03 address the unsafe condition. Accordingly, the NPRM is withdrawn.
