Q400 Airtanker Conversion

The Q400 Airtanker is the world’s most advanced airtanker – and one of the fastest turboprop planes in the world. The Cascade conversion of the initial Bombardier design meets FAR 25 standards, plus additional Transport Canada safety requirements for the fire-fighting role. Its STC certification makes the Q400 readily portable for approval by other foreign airworthiness authorities, including the FAA and EASA.
