The Agusta AZ.8L , or Agusta-Zappata AZ.8L , was an Italian airliner prototype first flown on 9 June
1958 . It was of conventional low-wing monoplane configuration with tricycle undercarriage and all-metal construction. Filippo Zappata's design grew out of a twin-engined transport designated AZ.1 that was never built.
When the AZ.8L failed to attract customers, Agusta abandoned the project to focus on its helicopter manufacturing operations, in particular a new Zappata design, the
A.101 .
