  • 2025-04089 — Airworthiness Directives; The Boeing Company Airplanes
    Type:Proposed Rule
    Citation:90 FR 12115
    Reading Time:about 11 minutes

    The Federal Aviation Administration (FAA) has proposed a new airworthiness directive for Boeing 787-8, 787-9, and 787-10 airplanes due to issues found with their forward pressure bulkhead during assembly, such as excessive gaps. These defects could lead to fatigue cracks that weaken the airplane's structure if not fixed. The proposed rule requires inspections and necessary repairs to prevent potential safety hazards. The FAA is accepting public comments on this proposal until April 28, 2025.

    Simple Explanation

    The FAA wants to make sure certain Boeing airplanes are safe because some part of the airplane might have gaps that could cause problems. They want the airplanes to be checked and fixed if needed, but they haven't said how much the fixes might cost exactly.

  • 2021-01744 — Airworthiness Directives; Airbus SAS Airplanes
    Type:Proposed Rule
    Citation:86 FR 10498
    Reading Time:about 12 minutes

    The Federal Aviation Administration (FAA) is proposing a new airworthiness directive for specific Airbus SAS Model A330-200 Freighter airplanes due to reports of broken brackets in the fire extinguishing system. This issue, caused by fatigue cracks from dynamic loading, could reduce fire suppression capability in the lower deck cargo compartment. The proposal requires the replacement of affected brackets and struts with reinforced versions, in line with instructions from the European Union Aviation Safety Agency (EASA). Comments on this proposal must be submitted by April 8, 2021, to address this potential safety hazard.

    Simple Explanation

    The FAA wants to fix a problem in some of Airbus's cargo airplanes because parts holding the fire extinguisher can break, which might make it harder to stop fires. They are asking people what they think about changing these parts to stronger ones to keep everyone safe.
