Activation of Ice Protection
The Federal Aviation Administration amends the airworthiness standards applicable to transport category airplanes certificated for flight in icing conditions. The rule requires a means to ensure timely activation of the airframe ice protection system. This rule is the result of information gathered from a review of icing accidents and incidents, and will improve the level of safety for new airplane designs for operations in icing conditions.
Airworthiness Directives; Bell Helicopter Textron Canada Model 427 Helicopters
We are adopting a new airworthiness directive (AD) for Bell Helicopter Textron Canada (BHTC) Model 427 helicopters. This AD results from mandatory continuing airworthiness information (MCAI) originated by the aviation authority of Canada to identify and correct an unsafe condition on an aviation product. Transport Canada, the aviation authority of Canada, with which we have a bilateral agreement, states that it has been determined that the existing hardware connecting the vertical fin to the tail rotor gearbox needs to be upgraded to prevent the vertical fin from becoming loose.
Airworthiness Directives; Eurocopter France Model AS 332 C, L, L1, and L2; AS 350 B3; AS 355 F, F1, F2, and N; SA 365 N and N1; AS 365 N2 and N3; SA 366 G1; EC 130 B4; and EC 155B and B1 Helicopters
We propose to adopt a new airworthiness directive (AD) for the specified model helicopters. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community. The MCAI states that the AD is issued following a manufacturing nonconformity found on one batch of the servo-control caps. With a defective servo-control, rotation of the distributor might not be stopped mechanically since only friction of inner seals holds the distributor sleeve in its position. The proposed
