Agusta-Zappata AZ.8L

The Agusta AZ.8L, also known as the Agusta-Zappata AZ.8L, took its maiden flight on June 9, 1958, as an Italian airliner prototype.

It featured a traditional low-wing monoplane design, a tricycle undercarriage, and was constructed entirely of metal.

Filippo Zappata’s concept originated from an unrealised twin-engined transport model called the AZ.1.

Following the lack of interest from potential buyers, Agusta decided to discontinue the AZ.8L project and shift its focus to helicopter production, specifically the new Zappata creation, the A.101.

The Italian Air Force utilised this aircraft for airline transport purposes.
