  • 2025-06066 — Airworthiness Directives; Thommen Aircraft Equipment AG Digital Air Data Computers
    Type:Rule
    Citation:90 FR 15304
    Reading Time:about 10 minutes

    The Federal Aviation Administration (FAA) has issued a new airworthiness directive (AD) for certain Thommen AC32 Digital Air Data Computers due to malfunctions occurring at low temperatures. This rule mandates the replacement of defective computers with ones that work correctly to ensure aircraft safety. Effective from May 15, 2025, the directive also includes additional helicopter models that might be affected and prohibits installing faulty parts on any aircraft. The rule aims to prevent issues with navigational data that could compromise flight control.

    Simple Explanation

    The FAA is making a new rule that says certain airplane computers need to be swapped out because they don't work in really cold weather, which could be dangerous. This rule tells people to use a good computer part instead, starting in May 2025, to help keep planes flying safely.

  • 2025-02795 — Establishment of Class E Airspace; Zeeland, MI
    Type:Rule
    Citation:90 FR 10454
    Reading Time:about a minute or two

    The Federal Aviation Administration (FAA) corrected a typographic error in a previously published final rule regarding airspace establishment at Zeeland, MI. Originally released in the Federal Register on December 13, 2024, this rule mistakenly included duplicate state identifiers, including an incorrect “SD” identifier. The corrected rule now accurately reflects that Zeeland, MI airspace should be associated with Ottawa Executive Airport, MI. This ensures that navigational data is accurate for implementation by April 17, 2025.

    Simple Explanation

    The FAA fixed a mistake in a rule about sky zones over Zeeland, Michigan, because they wrote the wrong place letters. Now, they made sure the sky zones map to the right airport, so airplane guides will be correct by April 2025.
