The PZL.43 was a Polish light bomber and reconnaissance aircraft designed in the mid-1930s by PZL in Warsaw. It was a development of the PZL.23 Karaś. Its main user was the Bulgarian Airforce who called it the Chaika (Чайка, gull).
==Design and development== The standard Polish light bomber and reconnaissance aircraft, the PZL.23 Karaś could not be exported because of licence restrictions on the use of the Polish-built (PZL) Bristol Pegasus engine. The PZL.43 was a development of the PZL.23, powered instead by a Gnome-Rhône 14K engine. It was first offered to Romania, but they rejected it in favour of domestic designs. The PZL was more successful in Bulgaria, then reforming their airforce after a period of post-World War I treaty constraints. An order for 12 aircraft was placed in April 1936.
