M-24, M-24bis by D.P.Grigorovich

Biplane flying boat, modification of the M-9. Aircraft was ordered by the Management of Naval Aviation. Project started on April 12, 1922 at GAZ-3 factory. Pre-production aircraft was factory-tested in Spring 1923 and rushed into production.

In 1924 first batch of 40 M-24's was transferred to naval aviation. Soon factory was swamped with pilot's complains about shortcomings and defects of the flying boat. Special panel investigated those complains, and decision was in the air to withdraw M-24 from service. Aircraft was rescued by crash of Junkers Ju-20 (major competitor for the M-24).

production of M-24 continued with several improvements under designation M-24bis. Engine was boosted to 260hp by replacing iron pistons with aluminum ones. M-24bis was put into production (Spring 1924) actually without D.P.Grigorovich, who at the time working at Aviazavod (Aircraft Works) No.1.

20 M-24bis were built on the GAZ-3 factory. Those were the last of the 'M'-line. Design based on the 1915 successful M-9 was completely obsolete in 1924.
