The FAA proposes to adopt a new airworthiness directive (AD) for all Leonardo S.p.a. Model A119 and AW119 MKII helicopters. This proposed AD was prompted by a report of an electrical failure of a starter-generator caused by a ruptured drive shaft. This proposed AD would require visually inspecting the drive shaft of an affected starter-generator and depending on the results, performing a dye penetrant inspection. Depending on the results of the dye penetrant inspection, this proposed AD would require replacing the starter- generator, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). 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 Schempp-Hirth Flugzeugbau GmbH (Schempp-Hirth) Model Ventus-2a and Ventus-2b gliders. 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 identifies the unsafe condition as the uncommanded extraction of the airbrakes on one or both wings, possibly resulting in reduced control of the glider. This proposed AD would require repetitively inspecting airbrake bell cranks and airbrake drive funnels for cracking, repetitively inspecting the clearance of the airbrake control system, and taking corrective action as necessary. This proposed AD would also require modifying the airbrake system, which is terminating action for the repetitive inspections. The FAA is proposing this AD to address the unsafe condition on these products.

NHTSA received two requests to extend the comment period for the Advance Notice of Proposed Rulemaking (ANPRM) regarding side underride guards that NHTSA published on April 21, 2023. The comment period for the ANPRM was scheduled to end on June 20, 2023. NHTSA is extending the comment period for the ANPRM by 30 days.

The FAA proposes to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) Model CF6-80E1A2, CF6-80E1A3, CF6-80E1A4, and CF6-80E1A4/B engines. This proposed AD was prompted by a manufacturer investigation that revealed that a certain forward outer seal and certain high-pressure turbine rotor (HPTR) stage 1 disks and rotating seals were manufactured from material suspected to contain iron inclusion, which may cause reduced material properties and a lower fatigue life capability. This proposed AD would require the replacement of the affected forward outer seal, HPTR stage 1 disks, and rotating seals. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This AD was prompted by reports of damaged decompression panels from operators. This AD requires repetitive inspections for damaged fastener holes on the vertical and bottom edges of the inward and outward blowing decompression panels installed on the forward and aft cargo compartment vertical sidewall linings and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
