The aircraft was developed from the Handley Page Hyderabad and named after Hinaidi, an RAF station in Iraq.

In 1923, Handley Page designed and built a new heavy bomber based on its W.8 airliner, the Hyderabad.

[2] The Hinaidi was an improved version of the Hyderabad built to meet Air Ministry Specification 13/29.

The first machine, the HP33 Hinaidi I -in fact an early production Hyderabad, J7745, with another engine and a change of fin and rudder[3]- first flew on 26 March 1927.

A re-engined version with two 480 hp Siddeley Jaguars was proposed, the HP44 Hinaidi III, but not built.
