PAC Cresco
open-in-new
<h2 id="design-and-development">Design and development</h2> <p>The Cresco is a <a href="/facts/Monoplane/2fLoovyH">low-wing monoplane</a> which, like the Fletcher but unlike most topdressers, has <a href="/facts/Tricycle_gear/sJa9zC3y">tricycle undercarriage</a> and places the cabin forward of the hopper, at the <a href="/facts/Leading_edge/7qs3oRtP">leading edge</a> of the wing - which gives the pilot of the Cresco a good field of vision. The high-lift wing has pronounced <a href="/facts/Dihedral_(aircraft)/T5aAmhnH">dihedral</a> on the outer span. The <a href="/facts/Prototype/q0yPLYdb">prototype</a> Cresco (ZK-LTP) had an <a href="/facts/Stabilator/WVn8oWFA">all-moving tailplane</a>, but was lost when the tailplane separated in flight, (the pilot parachuting to safety). Subsequent aircraft have had <a href="/facts/Tailplane/cBGTeTwM">conventional tails</a>. </p><p>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 <a href="/facts/Superphosphate/ftYnngg5">superphosphate</a> <a href="/facts/Fertiliser/ysh3r6NJ">fertiliser</a>, the Cresco is also used in the utility role, especially as a <a href="/facts/Parachuting/ndWLLtmG">skydiving</a> platform, where its fast <a href="/facts/Rate_of_climb/q8V71SqX">rate of climb</a> (1,560 ft/min, 7.9 m/s) has made it popular, and as a firefighting <a href="/facts/Water_bomber/4R9nv5Qm">water bomber</a>, a role it can perform with little alteration from its standard agricultural layout. One aircraft has been converted for <a href="/facts/Aeromagnetic_survey/k9YechB2">aeromagnetic survey</a>. A disadvantage in the utility role is the low internal volume available for the relatively high-powered engine. </p> <p>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) <a href="/facts/Pratt_%2526_Whitney_Canada/zXxvV3Tu">Pratt & Whitney Canada</a> <a href="/facts/Pratt_%2526_Whitney_Canada_PT6/3BVRP6gs">PT6-34AG</a>. </p><p>The <a href="/facts/PAC_750XL/azuHl9JH">PAC 750XL</a>, a <a href="/facts/Utility_aircraft/FVXWk9Vm">utility aircraft</a> 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 <a href="/facts/Hot_and_high/oR0It1qk">hot and high</a> conditions. </p> <h2 id="cresco-ii">Cresco II</h2> <p>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.<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a> </p> <h2 id="variants">Variants</h2> Cresco 08-600 Initial production version, powered by 447 kW (600 shp) <a href="/facts/Lycoming_LTP_101/SNsALIco">Lycoming LTP 101</a>-700A-1A engine.<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a> Cresco 08-750 More powerful version with 559 kW (750 shp) Pratt & Whitney PT6A-34AG engine.
