|Role||Two-seat touring/training monoplane|
|First flight||23 May 1958|
First flown on 21 May 1958 by Mieczysław Miłosz the PZL-102 was designed as a semi-aerobatic two-seat light monoplane and was later given the name Kos. The Kos was an all-metal low-wing cantilever monoplane with fabric tail control surfaces. It had a fixed tailwheel landing gear and the prototype had a nose-mounted 65 hp (48 kW) Narkiewicz WN-1 flat-four engine. The Kos had an enclosed cockpit for two side-by-side. After a number of prototypes the production aircraft (designated PZL-102B) first flew in October 1959, with Continental C90 engine and changed wing construction. Only short series was produced, because it needed imported engine.
Seven aircraft were sold abroad. Austrian aircraft were operated for agrospraying purposes. Tank filled with chemical agent was placed on the passenger seat.
One PZL-102 has been restored to airworthy condition (markings SP-EFA).
- Production variant with Continental C90 engine.
There is another PZL 102B restored in South Africa, based at Jack Taylor Airfield Krugersdorp, and one more in Brazil (PT-BGP)
