This AD requires a one-time inspection of the left- and right-hand main landing gear (MLG) downlock actuators or a review of the airplane maintenance records to determine the part number of each downlock actuator installed, and replacement of identified MLG downlock actuators with modified MLG downlock actuators. This AD results from a report of a failed downlock actuator, which resulted in the left MLG collapsing during taxi after landing. We are issuing this AD to prevent failure of the downlock actuator, which could prevent the MLG side stay from locking properly, resulting in collapse of the MLG during ground maneuvers or upon landing.

Rolls-Royce Deutschland Ltd & Co KG (formerly Rolls-Royce plc) Dart 528, 529, 532, 535, 542, and 552 Series Turboprop Engines
The FAA is adopting a new airworthiness directive (AD) for Rolls-Royce Deutschland Ltd & Co KG (formerly Rolls-Royce plc) (RRD) Dart 528, 529, 532, 535, 542, and 552 series turboprop engines. This AD would require repetitive inspections of high pressure turbine (HPT) blade platforms and shrouds, and reworking the engines if the inspections reveal excessive gaps between blade shrouds. This AD results from reports of HPT disk rim failures. We are issuing this AD to prevent HPT disk rim failures resulting in the release of portions of the HPT disk, uncontained engine failure, and damage to the airplane.

CFM International CFM56-5 and -5B Series Turbofan Engines
The FAA is superseding an existing airworthiness directive (AD) for CFM International CFM56-5 and -5B series turbofan engines. That AD requires exhaust gas temperature (EGT) harness replacement or the establishment of an EGT baseline and trend monitoring. That AD also requires replacement, if necessary, of certain EGT harnesses and EGT couplings as soon as a slow and continuous EGT drift downward is noticed after the effective date of that AD. This AD requires the same actions but for an increased population of affected EGT harnesses. This AD results from CFM International adding subsequently certified engine models to the list of engines that could have affected harnesses installed. We are issuing this AD to prevent unexpected deterioration of critical rotating engine parts due to higher than desired engine operating EGTs.

Turbomeca S.A. Engines
The FAA is revising an existing airworthiness directive (AD) for Turbomeca S.A. Arrius 2F turboshaft engines. That AD currently requires replacing certain O-rings on the check valve piston in the lubrication unit, at repetitive intervals. This AD requires the same actions except it reduces the applicability from all Turbomeca S.A. Arrius 2F turboshaft engines, to Turbomeca S.A. Arrius 2F turboshaft engines that have not incorporated modification Tf75. This AD results from Turbomeca S.A. introducing a check valve piston design requiring no O-ring. We are issuing this AD to prevent an uncommanded in-flight shutdown of the engine, which could result in a forced autorotation landing and damage to the helicopter.

Pratt & Whitney PW4077D, PW4084D, PW4090, and PW4090-3 Turbofan Engines
The FAA is superseding an existing airworthiness directive (AD) for Pratt & Whitney PW4077D, PW4084D, PW4090, and PW4090-3 turbofan engines that were reassembled with previously used high pressure compressor (HPC) exit brush seal packs and new or refurbished HPC exit diffuser air seal lands. That AD currently requires replacing the HPC exit inner and outer brush seal packs with new brush seal packs, or replacing the HPC exit brush seal assembly with a new HPC exit brush seal assembly. This AD requires replacing the HPC exit inner and outer brush seal packs with new brush seal packs, using either original equipment manufactured (OEM) parts, or FAA-approved part manufacturer approval (PMA) parts. This proposed AD also applies to engines reassembled with a PMA HPC exit inner and or outer brush seal packs. This AD results from a request to include PMA HPC exit inner and outer brush seal packs and to include the engines with PMA parts already installed, in the AD. We are issuing this AD to prevent uncontained engine failure, damage to the airplane, and injury to passengers.
