The chairman of the commission, John Path told Justice Minister Esmon Saimon their four month investigation found the A220 is not suitable for Vanuatu.
He said Air Vanuatu doesn't have pilots and engineers for the A220s and there is no hangar space for such planes.
Mr Path said Air Vanuatu is in a serious financial situation and buying the A220s would worsen its position.
Vanuatu announced ambitious growth plans in 2019, with plans to buy four aircraft from Bombardier, with the option for another four.
The company paid a deposit of $US17.5 million dollars.
