The Avro Manchester was designed with great consideration for ease of manufacture and repair. The fuselage of the aircraft comprised longitudinal stringers or longerons throughout, over which an external skin of aluminium alloy was flush-riveted for a smooth external surface. The wings were of a two-spar construction, the internal ribs being made of aluminium alloys; fuel was contained with several self-sealing fuel tanks within the wings. The tail shared a similar construction to the wing, featuring a twin fin-and-rudder configuration that provided good vision for the dorsal gunner.
