✈️Proposed Airworthiness Directive for MHI RJ Aviation Maintenance
The FAA proposes to adopt a new airworthiness directive (AD) for all MHI RJ Aviation ULC Model CL-600-2C10 (Regional Jet Series 700, 701 & 702), CL-600-2C11 (Regional Jet Series 550), CL-600-2D15 (Regional Jet Series 705), CL-600-2D24 (Regional Jet Series 900), and CL-600-2E25 (Regional Jet Series 1000) airplanes. This proposed AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is proposing this AD to address the unsafe condition on these products.

Learn More🚁New Airworthiness Directive for Siam Hiller Helicopters Issued
The FAA is adopting a new airworthiness directive (AD) for certain Siam Hiller Holdings, Inc. (Siam Hiller), Model UH-12E (Army OH-23G and H-23F) and UH-12E-L helicopters. This AD was prompted by reports of cracks found in a main rotor (M/R) transmission drive shaft (drive shaft). This AD requires inspecting certain M/R drive shafts for a crack, prohibits installing certain M/R drive shafts unless the inspection is done, and prohibits using certain paint strippers. The FAA is issuing this AD to address the unsafe condition on these products.

Learn More🚁Proposed Rulemaking on Airworthiness for Airbus Helicopters
The FAA proposes to supersede Airworthiness Directive (AD) 2020-06-12, which applies to certain Airbus Helicopters Model AS 332L2 and EC 225LP helicopters. AD 2020-06-12 requires determining the accumulated hours time-in-service (TIS) of certain part-numbered main gearbox (MGB) suspension bar attachment bolts (bolt) and certain part- numbered MGB suspension bar attachment fittings (fitting), applying a life limit add-on factor, and inspecting the torque of certain MGB suspension bar attachment nuts (nuts). Since the FAA issued AD 2020-06- 12, the manufacturer developed a design improvement, and the FAA determined modifying the helicopter is necessary. This proposed AD would retain the actions required by AD 2020-06-12 and would also require modification of the MGB suspension bar, inspection of the torque, and corrective actions. This proposed AD would also allow credit for the initial service life calculations if certain requirements are met and would prohibit installing a certain bolt after the modification is accomplished on any helicopter. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to adopt a new airworthiness directive (AD) for all ATR--GIE Avions de Transport R[eacute]gional Model ATR42 and Model ATR72 airplanes. This proposed AD was prompted by a design review that determined that the inspection interval of the pressure regulator and shut-off valve (PRSOV) functional test must be reduced to meet the design safety objectives, due to a risk of dormant failures. This proposed AD would require repetitive functional tests of each PRSOV, and applicable corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.
