CM173 Super magister

As a private venture, Potez had finally built and flown the Super Magister CM-173, in order to provide a modernized trainer as a follow-on and replacement for air forces already using the CM-170.

Main innovations was the Martin-Baker/Hispano ejection seats set in a new canopy giving improved view and lower drag. Radio equipment was modernized in line with modern requirements, fuel tankage were increased from 965 l to 1200 l and the ailerons combine the large area and powered control which were alternatives in the older Magisters. Apart from these improvements, the company stated that the structures of the CM-170 and CM-173 Magister was interchangeable. 

The prototype Super Magister made its first flight at Toulouse on 8 June 1964, with test pilot Jacques Grangette at the controls and Pierre Caneill as a flight test engineer. 

CM-173 name was consistent with those used by Castello-Mauboussin. The aircraft was later upgraded and renamed Potez 94.
