Here is a commissioned piece done for the Irish Air Corps dated November 2019.
The Pilatus PC-9 is a single-engine, low-wing tandem-seat turboprop training aircraft and forms the main pilot training aircraft of this armed force.
I had the opportunity to see the aircraft up close at an air show in the UK, and this allowed
me to take many close-up shots of the airframe saving me a ton of research time!
All the existing 7 airframes will be available for order at thedesignhangar.com online store coming 2021:
