The prototype Aerospatiale AS 350 Ecureuil helicopter, F-WVKH (c/n 001), powered by an Avco Lycoming LTS-101 turboshaft, first flew June 27 1974.
Still in production today.
If my memory serves me - ZK-HMY (c/n 1052) was the first Squirrel on the ZK register.
It arrived at Lyttelton in April 1979 and was registered to Airwork (NZ) Ltd of Christchurch on the 26th.
"Bill Black's machine".
Its history was previously shown at :-
After export from NZ it popped up with Island Hoppers in Fiji as DQ-HMY.
There have been approximately 325 ZK registrations allocated to Squirrels !
