1 RULES: Model 45 Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires a general visual inspection for damage of wiring (including chafing, pinched wires, and exposed wires) and correct routing of wires in the left and right circuit breaker panels, and related investigative and corrective actions if necessary. This AD
2 PROPOSED RULES: Turbofan Engines
We propose to supersede an existing airworthiness directive (AD) that applies to all RR model RB211524G2T19, 524G3T19, 524H T36, and 524H2T19; and RB211Trent 55361, 553A261, 55661, 556A2 61, 556B61, 556B261, 56061, 560A261; RB211Trent 76860, 77260, 772B60; and RB211Trent 87517, 87717, 88417, 884B17, 89217, 892B 17, and 89517 turbofan engines that
3 PROPOSED RULES: Pacific Aerospace Limited Airplanes
We propose to adopt a new airworthiness directive (AD) for Pacific Aerospace Limited Models FU24954 and FU24A954 airplanes modified with an unapproved hopper lid modification. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe

7 RULES: and 114TC Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires an inspection of the elevator spar for cracks and, if any crack is found, either replacement with a serviceable elevator spar that is found free of cracks or repair/ modification with an FAAapproved method. This AD also requires reporting to the FAA
8 RULES: 50 Series Turbofan Engines
We are superseding an existing airworthiness directive (AD) for General Electric Company (GE) CF645 and CF650 series turbofan engines with certain lowpressure turbine (LPT) rotor stage 3 disks installed. That AD currently requires initial and repetitive borescope inspections of the highpressure turbine (HPT) rotor stage 1 and stage 2 blades for
9 PROPOSED RULES: Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above 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
10 RULES: M7 Aerospace LP Airplanes
We are adopting a new airworthiness directive (AD) for certain M7 Aerospace LP Models SA226T, SA226T(B), SA226TC, and SA226AT airplanes. This AD requires repetitive replacement and inspection of certain elevator, rudder, aileron, and ailerontorudder interconnect primary control cables, and checking and setting of flight control cable tension.
