Design and development

The basic P.166 was a development of the P.136 amphibian and flew for the first time on 26 November 1957.[1] The P.166 had a new fuselage and tail unit but retained the wing and engines from the P.136. Several were purchased for use as executive transports or as feeder and taxi aircraft. The improved P.166B was more powerful and had up to 10 seats; a prototype was first flown on 27 March 1962.

A further version, the 12 seater P.166C, with improved undercarriage, first flew on 2 October 1964.

A turboprop-powered variant, the P.166D was developed with Lycoming LTP-101 engines and it first flew on 3 July 1976.
