Combining the engine and wings of the PAC Cresco with a new larger fuselage and modified tail, all versions to date have been powered by a 750 hp (560 kW) Pratt & Whitney Canada PT6 turboprop.

[citation needed] In 2012, Pacific Aerospace achieved certification for the P-750 XSTOL against ICAO Annex 6 for Single Engine IFR Commercial Passenger Transport Operations.

[6] To increase payload, a weight-reduction programme for 2020 replaces flight-control surfaces in aluminium by composite, installs lighter seating, and strips out cabin components.

[6] Financed by UK start-up Arcus Fire, the F-25 is an aerial firefighting variant, scheduled to secure its supplemental type certificate in 2021.

The $2.2 million aircraft competes against other types like the Polish PZL Dromader, targeting a 100 units market within five years.

In the parachuting role, the high-lift wings from the Cresco and relatively high power-to-weight ratio enable the PAC 750 to take a load of parachutists to 12,000 feet (3,700 m) and return to land in 10 minutes.

A wider market was subsequently sought, and examples have been sold for use in utility roles, including freight, agricultural applications, passenger operations, aerial photography and surveying.

Twelve aircraft have now been extensively modified for geo-survey work, being fitted with a magnetic anomaly detector sting tail.

The P-750 XSTOL is used in South Africa by NatureLink on United Nations Humanitarian Air Services / World Food Programme contracts.
