Airworthiness Directives; Cessna Aircraft Company Models 525, 525A, and 525B Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Cessna Aircraft Company (Cessna) Models 525, 525A, and 525B airplanes. This proposed AD would require you to inspect the lower wing skin structure, forward wing spar, lower fuselage skin, fairings, and the external fairing frames for corrosion; repair any damage found; apply a corrosion inhibitive sealant to the fuselage fairings before reinstalling; and disable the cockpit mounted pilot relief tube. This proposed AD results from leaking of the cockpit mounted pilot relief tube, which caused corrosion of the airplane structure. We are proposing this AD to detect and correct any damage from corrosion of the airplane structure. Corrosion of the airplane structure could cause structural degradation and lead to structural failure of the airplane with consequent loss of control.

Airworthiness Directives; Rolls-Royce plc (RR) RB211 Trent 768-60, 772-60, 772B-60, and 772C-60 Turbofan Engines
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) provided by the aviation authority for the United Kingdom to identify and correct an unsafe condition on an aviation product. The MCAI states the following:
Modification of Class D Airspace; Castle Airport, Atwater, CA
This rule modifies Class D airspace at Castle Airport, Atwater, CA. This action lowers the ceiling of the Atwater, Castle Class D airspace to below 2.000 feet mean sea level (MSL), changes the southern boundary of the airspace and add an extension to the north. FAA is taking this action to provide controlled airspace for the safety of aircraft executing Standard Instrument Approach Procedures (SIAPs) and other Instrument Flight Rules (IFR) operations at Castle Airport. Except for editorial changes, this rule is the same as the Notice of Proposed Rule Making.
Airworthiness Directives; Bell Helicopter Textron, Inc. Model 205A, 205A-1, 205B, 212, 412, 412CF, and 412EP Helicopters
This amendment supersedes an existing airworthiness directive (AD) for the specified Bell Helicopter Textron, Inc. (Bell) Helicopters. That AD currently requires inspecting each affected tail rotor blade (blade) forward tip weight retention block (tip block) and the aft tip closure (tip closure) for adhesive bond voids, and removing any blade with an excessive void from service. That AD also requires modifying certain blades by installing shear pins and tip closure rivets. This amendment contains the same requirements but expands the applicability to include other part and serial-numbered blades. This AD also clarifies the requirement to re-identify the modified blade by adding ``FM'' after the part number and also requires dynamically balancing the tail rotor. The existing AD was prompted by five occurrences of missing tip blocks or tip closures resulting in minor to substantial damage. This amendment was prompted by the determination that the AD should apply to other affected part and serial-numbered blades. The actions specified by this AD are intended to prevent loss of a tip block or tip closure, loss of a blade and subsequent loss of control of the helicopter.
