The FAA is adopting a new airworthiness directive (AD) for all Eagle Aircraft (Malaysia) Sdn. Bhd (Eagle Aircraft) Model Eagle 150B airplanes. This AD requires you to inspect certain canard inboard flap hinge support brackets (initially prior to further flight and repetitively before the first flight of each day) and perform any necessary follow-up action. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authorities for Australia and Malaysia. We are issuing this AD to prevent failure of the canard inboard flap hinge support brackets caused by undetected cracks. This failure could result in asymmetric flap deployment and the inability to lower or raise the flaps with consequent loss of control of the airplane.

Bell Helicopter Textron Canada Model 407 Helicopters
This amendment supersedes an existing airworthiness directive (AD) for Bell Helicopter Textron Canada (BHTC) Model 407 helicopters which requires a one-time replacement of certain oil cooler blower bearings. Also, the existing AD requires adding a limitation and caution to the rotorcraft flight manual (RFM) and inspecting, replacing, and lubricating certain bearings at specified intervals. This amendment adds certain segmented drive shaft bearings to the applicability and requires modifying the oil cooler blower inlet ducts and airflow shields and replacing certain bearings. Thereafter, this amendment requires removing the current temporary limitations and inserting revised limitations into the RFM. This amendment also requires revising the inspection and lubrication requirements. This amendment is prompted by several cases of bearing failure. The addition of certain segmented drive shaft bearings is due to two recent failures. The actions specified by this AD are intended to prevent failure of a bearing, loss of tail rotor drive, and a subsequent loss of directional control of the helicopter.

Pratt & Whitney JT9D-3A, -7, -7A, -7AH, -7H, -7F, -7J, -20, and -20J Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) for Pratt & Whitney (PW) JT9D-3A, -7, -7A, -7AH, -7H, -7F, -7J, -20, and - 20J turbofan engines. This AD clarifies a life limit for certain part numbers of 6th stage low pressure turbine (LPT) air seals, and requires their removal from service before accumulating 15,000 cycles-since-new (CSN). This AD results from reports of certain 6th stage LPT air seals possibly not being life tracked due to confusion from updates to the engine manuals. We are issuing this AD to prevent failure of the 6th stage LPT air seal, which could cause LPT damage resulting in an uncontained engine failure.

Lycoming Engines (Formerly Textron Lycoming), Direct-Drive Reciprocating Engines
The FAA is adopting a new airworthiness directive (AD) that supersedes an existing AD, for Lycoming Engines (formerly Textron Lycoming), direct-drive reciprocating engines (except O-145, O-320H, O- 360E, LO-360E, LTO-360E, O-435, and TIO-541 series engines). That AD currently requires inspection of the crankshaft gear installation and rework or replacement of the gears where necessary after a propeller strike, sudden stoppage, at overhaul, or whenever gear train repair is required. This AD requires the same actions but makes the correction that the existing gear retaining bolt and lockplate be removed from service and new hardware installed, and revises the definitions for sudden stoppage and propeller strike. This AD results from a change to the definition of a propeller strike or sudden stoppage. We are issuing this AD to prevent loosening or failure of the crankshaft gear retaining bolt, which may cause sudden engine failure.

Saab Model SAAB 340B Series Airplanes Equipped with Hamilton Sundstrand Propellers
This amendment adopts a new airworthiness directive (AD), applicable to certain Saab Model SAAB 340B series airplanes equipped with Hamilton Sundstrand propellers. This amendment requires a one-time inspection of two remote controlled circuit breakers (RCCB), located in specific electrical compartments, to identify the part number, and replacement of the RCCBs with new RCCBs having a different part number if necessary. This action is necessary to ensure removal of 35-ampere (amp) RCCBs on a 50-amp electrical circuit. Incorrect RCCBs on an electrical circuit could result in erroneous tripping of the RCCBs (even though an overload condition does not exist), premature failure of the RCCBs, loss of power to the feather pump system, and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
