The FAA is superseding an existing airworthiness directive (AD) for CFM International, S.A. CFM56-5B series turbofan engines. That AD requires reviewing exhaust gas temperature (EGT) monitoring records to determine EGT margin deterioration, and for airplanes where both engines have greater than 80 [deg]centigrade (C) of EGT margin deterioration, borescope-inspecting the high-pressure compressor (HPC) of both engines. That AD also requires removing from service any engine that does not pass the borescope inspection and, if both engines pass, replacing one of the engines with an engine that has 80 [deg]C or less of EGT margin deterioration. That AD also requires continuous monitoring of EGT margin deterioration on engines in service to prevent two engines on an airplane from having greater than 80 [deg]C of EGT margin deterioration. This AD: <bullet> Reduces the number of engine models affected; <bullet> Continues to monitor EGT margin deterioration; <bullet> Lowers the EGT margin threshold from 80 [deg]C to 75 [deg]C; <bullet> Removes FADEC software version 5.B.Q and earlier versions from the engine as mandatory terminating action to the continuous EGT margin deterioration monitoring, for certain engine models; <bullet> Removes the requirement to borescope inspect; and <bullet> Removes the requirement to replace one of the engines with an engine that has 80 [deg]C or less deterioration of EGT margin as a corrective action. This AD results from a reduction of the affected engine models listed in AD 2009-01-01 from 25 to 19, a reduction in the engine EGT margin deterioration threshold from 80 [deg]C to 75 [deg]C, the introduction of terminating action to the continuous EGT monitoring for certain engines, and a change to the removal plan for the remaining engines if the EGT margin deterioration is greater than 75 [deg]C. We are issuing this AD to prevent HPC stalls, which could prevent continued safe flight or landing.

Turbomeca Arriel 1B, 1D, 1D1, and 1S1 Turboshaft Engines
The FAA is superseding an existing airworthiness directive (AD) for certain Turbomeca Arriel 1B, 1D, 1D1, and 1S1 turboshaft engines. That AD requires initial and repetitive relative position checks of the gas generator 2nd stage turbine blades on Turbomeca Arriel 1B (that incorporate Turbomeca Modification (mod) TU 148), Arriel 1D, 1D1, and 1S1 turboshaft engines that do not incorporate mod TU 347. That AD also requires initial and repetitive replacements of 2nd stage turbines on Arriel 1B, 1D, and 1D1 engines. This AD requires lowering the initial and repetitive thresholds for replacement of 2nd stage turbines on Arriel 1B, 1D, and 1D1 engines. This AD results from reports of new cases of failures of 2nd stage turbine blades since we issued AD 2008-07-01. We are issuing this AD to prevent the failure of 2nd stage turbine blades, which could result in an uncommanded in- flight engine shutdown, and a subsequent forced autorotation landing or accident.

The FAA is superseding an existing airworthiness directive (AD) for the Dowty Propellers, propeller models listed above. That AD currently requires, for all Dowty Rotol propellers, visual inspections for seizure and for cadmium plating of the blade pitch change operating links and eyebolt fork assemblies. That AD also requires replacement or heat-treatment of the blade pitch change operating links and eyebolt fork assemblies, if necessary. This AD requires the same actions, but only for certain propeller models. This AD results from the FAA determining that AD 70-16-02 does not apply to all propellers, since current Dowty propellers are differently designed. We are issuing this AD supersedure to specify the affected propeller models, and to prevent seizure or embrittlement and cracking of the blade pitch change operating links and eyebolt fork assemblies, which could result in reduced controllability of the airplane.
