The AgustaWestland AW109, originally the Agusta A109, is a lightweight, twin-engine, eight-seat multi-purpose helicopter designed and initially produced by the Italian rotorcraft manufacturer Agusta. It was the first all-Italian helicopter to be mass-produced. Its production has been continued by Agusta’s successor companies, presently Leonardo S.p.A. (formerly AgustaWestland, merged into the new Finmeccanica since 2016).
