Proposed Amendment of Class E Airspace; Point Thomson, AK
This action proposes to modify the airspace at Point Thomson, AK by establishing Class E Airspace at Point Thomson Airstrip Airport, Point Thomson, AK. This will accommodate aircraft using a new Area Navigation (RNAV) Global Positioning System (GPS) standard instrument approach procedures at the airport. The FAA is proposing this action to enhance the safety and management of aircraft operations at the airport.
Airworthiness Directives; Eurocopter Deutschland GmbH Model Helicopters
We propose to adopt a new airworthiness directive (AD) for Eurocopter Deutschland GmbH (Eurocopter) Model EC135 P1, P2, P2+, T1, T2, and T2+ helicopters to require inspecting each linear transducer bearing (bearing) for freedom of movement. This proposed AD would also require replacing the bearing if there is binding or rough turning or if there is chafing or damage on the lower side of the floor. Also, this proposed AD would require modifying and re-identifying a certain rod. This proposed AD is prompted by an incident involving limited control of a tail rotor because of the binding of a bearing. The proposed actions are intended to detect and replace each bearing subject to binding, which could lead to subsequent loss of control of the helicopter.
Airworthiness Directives; Alexander Schleicher GmbH & Co. Segelflugzeugbau Sailplanes
We propose to adopt a new airworthiness directive (AD) for all Alexander Schleicher GmbH & Co. Segelflugzeugbau Models AS-K13, Ka2B, Ka 6, Ka 6 B, Ka 6 BR, Ka 6 C, Ka 6 CR, K7, K8, and K 8 B sailplanes that would supersede an existing AD. 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 describes the unsafe condition as misalignment of the automatic elevator control connection. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; Hamilton Standard Division and Hamilton Sundstrand Corporation Propellers
We propose to adopt a new airworthiness directive (AD) for Hamilton Standard Division model 6/5500/F and 24PF and Hamilton Sundstrand Corporation model 14RF, 14SF, 247F, and 568F series propellers. This proposed AD was prompted by the amount of corrosion detected during major inspections (MIs). This proposed AD would require incorporating inspections, based on a calendar time, into the propeller maintenance schedule. We are proposing this AD to prevent corrosion that could result in propeller failure and loss of airplane control.
