Airworthiness Directives; BAE Systems BAe 146 and Avro 146-RJ. Final rule. SUMMARY: This 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: Reports have been received of finding corrosion at the Frame 29 wing-to-fuselage attachment lug plate joint. This condition, if not detected and corrected, could result in a degradation of the structural integrity of Frame 29 and the wing-to-fuselage attachment. The unsafe condition is degradation of the structural integrity of Frame 29 and the wing-to-fuselage attachment, which could result in loss of control of the airplane. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective March 4, 2010.

Airworthiness Directives; Airbus A330-201, -202, -203, -223, -243, -301, -302, -303, -321, -322, -323, -341, -342, and -343; Model A340-211, -212, -213, -311, -312, and - 313; and Model A340-541 and -642. Final rule. SUMMARY: This 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: During a scheduled maintenance inspection on the MLG [main landing gear], the bogie stop pad was found deformed and cracked. Upon removal of the bogie stop pad for replacement, the bogie beam was also found cracked. A second bogie beam crack has subsequently been found on another aircraft, located under a bogie stop pad which only had superficial paint damage. This condition, if not detected and corrected, could result in the aircraft departing the runway or to the bogie detaching from the aircraft or gear collapses, which would all constitute unsafe conditions at speeds above 30 knots. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective March 4, 2010.

Airworthiness Directives; Eurocopter AS332L1, AS332L2, and EC225LP Helicopters. Final rule; request for comments. SUMMARY: This AD results from mandatory continuing airworthiness information (MCAI) issued by the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community. The MCAI states: ''Recently, a report was received concerning the discovery of fragments of a plastic blanking plug (fitted to the harness belt buckle 5th attachment point) inside a seat harness belt buckle. Over time, this blanking plug hardens and becomes brittle. This condition, if not corrected, can lead to failure of the plug and fragments being caught inside the buckle, causing interference and preventing the belt from being released during an emergency evacuation of the aircraft.'' This AD requires actions that are intended to address this unsafe condition. DATES: This AD becomes effective on February 12, 2010

Airworthiness Directives; Eurocopter SE3160, SA315B, SA316B, SA316C, and SA319B Helicopters. Final rule; request for comments. SUMMARY: This amendment supersedes an existing airworthiness directive (AD) for the specified Eurocopter France (Eurocopter) model helicopters. The existing AD requires certain inspections of a main rotor blade (blade) manufactured under a Parts Manufacturer Approval under Supplemental Type Certificate (STC) SH778GL. The AD requires inspecting each affected root end bolt (bolt) and bolt- hole for corrosion or a crack on the blade root end fitting (fitting) or in a bolt-hole. For certain serial-numbered blades, the AD also requires a one-time pull test on each fitting and blade root end doubler (doubler) to detect disbonding. This AD requires certain inspections for voids in any doubler or fitting and for paint cracks along the forward and aft edge of the blade fitting. Also, this AD requires inspecting the blade tip weight housing attachment. This AD also requires replacing unairworthy blades with airworthy blades. This amendment is prompted by reports from the STC holder of disbonds at the fittings, doublers, and the tip weight fitting. The actions specified by this AD are intended to prevent blade failure and subsequent loss of control of the helicopter. DATES: Effective February 12, 2010.

Airworthiness Directives; Fokker F.28 Mark 0070 and 0100. Final rule. SUMMARY: This 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: Several cases have been reported where a passenger door actuator detached from the passenger door. This caused the passenger door to drop to the platform in an uncontrolled manner. This condition, if not corrected, could result in injury to persons on the ground and damage to the aircraft. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective March 4, 2010.
