Airworthiness Directives; Honeywell International Inc. TPE331 Series Turboprop, and TSE331-3U Model Turboshaft Engines
The FAA proposes to adopt a new airworthiness directive (AD) for certain Honeywell International Inc. TPE331 series turboprop, and TSE331-3U model turboshaft engines. This proposed AD would require implementing a new flight cycle counting method for first, second, and third-stage turbine rotors used in aircraft that make multiple takeoffs and landings without an engine shutdown, and removing turbine rotors from service that have reached or exceeded their cycle life limits. This new flight cycle counting method would require determining total equivalent cycles accrued. This proposed AD results from several reports of uncontained turbine rotor separation on engines used in special-use operations. We are proposing this AD to prevent uncontained failure of the turbine rotor due to low-cycle-fatigue (LCF), and damage to the aircraft.

Notice of Opportunity for Public Comment on Surplus Property Release at Craig Field Airport, Selma, AL
Under the provisions of Title 49, U.S.C. Section 47153(c), notice is being given that the FAA is considering a request from the Craig Field Airport and Industrial Authority to waive the requirement that a 0.93-acre parcel of surplus property, located at the Craig Field Airport, be used for aeronautical purposes.
Airworthiness Directives; AvCraft Dornier Model 328-100 Airplanes
The FAA is revising an existing airworthiness directive (AD) that applies to all AvCraft Dornier Model 328-100 airplanes. That AD currently requires revising the airplane flight manual (AFM) to provide the flightcrew with additional information regarding procedures to ensure complete pressurization of the hydraulic lines for the flaps. The existing AD also requires, for certain airplanes, modifying of the flap actuators of the flight controls. We issued that AD to prevent an uncommanded retraction of the flaps during takeoff, which could result in an aborted takeoff and consequent potential for runway overrun. This new AD allows the removal of the AFM revisions after modifying the flap actuators of the flight controls. This AD results from the determination that the AFM revisions are not necessary after modifying the flap actuators of the flight controls. We are issuing this AD to prevent an uncommanded retraction of the flaps during takeoff, which could result in an aborted takeoff and consequent potential for runway overrun.
Airworthiness Directives; General Electric Company CF34-1A, -3A, -3A1, -3A2, -3B, and -3B1 Series Turbofan Engines
The FAA is superseding an existing airworthiness directive (AD) for General Electric Company (GE) CF34-3A1 and -3B1 series turbofan engines. That AD requires initial and repetitive visual inspections and eddy current inspections (ECIs) of certain stage 5 low pressure turbine (LPT) disks and stage 6 LPT disks, installed in GE CF34-3A1 and -3B1 series turbofan engines. Those engines are installed in certain Bombardier Canadair Regional Jet (RJ) airplanes. This AD requires the same initial and repetitive visual inspections and ECIs, but adds SNs to the affected disk population for RJ airplanes. This AD also adds GE CF34-1 and -3 series turbofan engines with certain stage 5 and stage 6 LPT disks, to the applicability section. Those engines are installed in certain Bombardier Canadair Business Jet (BJ) airplanes. Also, this AD requires eventual replacement of the affected disks as terminating action to the repetitive inspections. This AD results from the discovery of an additional population of suspect stage 5 LPT disks and stage 6 LPT disks that could fail due to low-cycle fatigue cracking that may start at the site of an electrical arc-out on the disk. We are issuing this AD to prevent low-cycle-fatigue (LCF) failure of stage 5 LPT disks and stage 6 LPT disks, which could lead to uncontained engine failure.
