  • 2021-00044 — Airworthiness Directives; Piper Aircraft, Inc. Airplanes
    Type:Rule
    Citation:86 FR 3769
    Reading Time:about 32 minutes

    The Federal Aviation Administration (FAA) has issued a new airworthiness directive (AD) targeting certain Piper Aircraft models. This directive was spurred by a report of wing separation due to fatigue cracking in an unseen area of the wing's main spar. The rule mandates that operators calculate service hours to plan inspections, check specific bolt holes for cracks, and replace any compromised wing spars. The overall objective is to address and mitigate the identified safety risks associated with these aircraft models.

    Simple Explanation

    The FAA is making sure some Piper airplanes are safe by checking if their wings are still strong and don't have cracks, so they don't fall off while flying. They're asking airplane owners to look at the wings often and fix any cracks they find.

  • 2025-02381 — Airworthiness Directives; Embraer S.A. (Type Certificate Previously Held by Yaborã Indústria Aeronáutica S.A.; Embraer S.A.) Airplanes

    Type:Rule
    Citation:90 FR 9197
    Reading Time:about 21 minutes

    The Federal Aviation Administration (FAA) has issued a new rule updating airworthiness directives for certain Embraer S.A. airplanes. This regulation replaces a previous directive and requires airlines to revise their maintenance or inspection programs to include new or stricter safety standards and structural changes necessary to prevent potential failures. The updated requirements aim to address issues like fatigue cracking, which can reduce the structural integrity of the aircraft, and possible safety hazards from latent system failures or ignition sources in fuel tanks. The new rule takes effect on March 17, 2025, affecting 662 airplanes in the U.S.

    Simple Explanation

    The FAA made new rules for certain airplanes to make sure they're super safe by checking and fixing them more often. This helps keep them from breaking or catching fire by accident, starting in March 2025.

  • 2024-28788 — Airworthiness Directives; ATR-GIE Avions de Transport Régional Airplanes
    💰
    Type:Rule
    Citation:89 FR 97502
    Reading Time:about 13 minutes

    The Federal Aviation Administration (FAA) has updated an existing airworthiness directive for certain ATR-GIE Avions de Transport Régional airplanes. This update involves adding more restrictive maintenance or inspection requirements to ensure these airplanes remain safe to fly. The decision to supersede the previous rule came after determining that these additional precautions were needed due to potential risks such as fatigue cracking. The FAA aims to tackle these potential safety issues to maintain the structural integrity of the aircraft.

    Simple Explanation

    The FAA has told some airplanes to check up more often and fix certain parts to make sure they are always safe to fly, protecting people inside from parts that might get too tired and crack. They're doing this because they found out that these airplanes need extra care to stay strong and safe.
