Six engine, but it demonstrated none of the operational vices of the larger aircraft and went on to become perhaps the most successful British-built commercial passenger aircraft of the 1930s.

At the start of [Vous devez être inscrit et connecté pour voir ce lien] many (Dragon) Rapides were impressed by the British armed forces and served under the name de Havilland Dominie.
They were used for passenger duties and radio navigation training.
Over 500 more were built specifically for military purposes, powered by improved [Vous devez être inscrit et connecté pour voir ce lien], to bring total production to 731.
Many survivors entered commercial service after the war, and 81 were still flying on the British register in 1958.
Dominie production was by both de Havilland and Brush Coachworks Ltd, the latter making the greater proportion.

The DH.89 proved a very durable aircraft despite its relatively primitive plywood construction and many were still flying in the early 2000s.
Several Rapides are still operational in the UK and several suppliers still offer pleasure flights in them.
Two Rapides are still airworthy in New Zealand.
