The Piel CP.70 Beryl is a French twin-seat, single-engine sport aircraft designed by Claude Piel. It was first flown in France in the 1960s and marketed for amateur construction.[1][2]
Designed by Claude Piel, the Beryl uses the same wing design as the Piel Emeraude but with a new fuselage, exchanging the Emeraude's side-by-side configuration seating for seating in tandem. As originally designed, the aircraft is fitted with fixed, tricycle undercarriage with a steerable nosewheel. Construction throughout is of doped fabric-covered wood.[2][3][4]
An aerobatic version, designated the CP.750 was also developed. This differs from the basic CP.70 in having a reduced wingspan, fixed tailwheel undercarriage and a slightly longer fuselage. It retains the CP.70's wooden wings, but the fuselage is built of welded steel tube and still covered in fabric.[3]
The Beryl has been homebuilt by amateur constructors and in 2009 there were still four examples active on the French civil aircraft register. The prototype F-PMEQ, completed in 1965 with tricycle undercarriage, was still active in 2014 modified as a CP.703 with tail-wheel undercarriage. Examples of the design have also been completed in Brazil and the United States.
