MI HB4898

Exempts parts and materials affixed to aircraft owned by domestic air carriers from use tax if the aircraft has a maximum certificated takeoff weight of at least 6,000 pounds and is used solely for transporting air cargo, passengers, or a combination thereof, simplifying prior eligibility criteria.

Exempts the sale of parts or materials affixed to aircraft from use tax without requiring the aircraft to leave the state within 15 days or meet specific residency conditions, removing previous restrictions.

Exempts aircraft temporarily located in Michigan for sale, prepurchase evaluation, customization, improvement, maintenance, or repair from use tax if the aircraft leaves the state within 15 days after completion and is not based or registered in Michigan before or after the transaction.

Adds "aircraft" definition to exclude unmanned aerial vehicles and updates terminology for "Federal Aviation Administration" for consistency.

Takes effect 90 days after enactment; directs legislature to annually appropriate state general fund money to the school aid fund to compensate for any revenue loss from this exemption.
