The PAC Cresco is a
Pacific Aerospace Corporation in Hamilton, New Zealand. The Cresco was superseded by the PAC P-750 XSTOL in the early 21st century, but in 2019 was returned to production with the first new aircraft being completed 3 December 2020.[1]
Design and development
The Cresco is a
dihedral on the outer span. The prototype Cresco (ZK-LTP) had an all-moving tailplane, but was lost when the tailplane separated in flight, (the pilot parachuting to safety). Subsequent aircraft have had conventional tails
.
Sales of the Cresco were not as impressive as those of the piston-engine powered Fletcher, with only 39 examples being built before production was terminated. The Cresco has been sold in several countries and has pioneered new utility roles not explored by the Fletcher. Although used primarily to spread
water bomber, a role it can perform with little alteration from its standard agricultural layout. One aircraft has been converted for aeromagnetic survey
. A disadvantage in the utility role is the low internal volume available for the relatively high-powered engine.
The Cresco is normally flown by a single pilot, but has a second seat in all versions. It can carry nine sky divers. Usual powerplant is a 750 hp (560 kW) Pratt & Whitney Canada PT6-34AG.
The
PAC 750XL
, a utility aircraft was derived from the Cresco, and retains its high-lift wing. As of January 2019 120 PAC 750XL's have been produced and it remains in high demand as an uncompromising utility aircraft able to operate in hot and high conditions.
Cresco II
On 17 December 2019 Pacific Aerospace posted on Facebook an announcement by CEO Mark Crouch that the type would return to production as the Cresco II, with some modifications regarding pilot safety and comfort, for the New Zealand customer Rural Air Work Ltd.[2]
