Bombardier is to conduct cold-weather trials of its Q400 turboprop in the Siberian republic of Yakutia in a bid to convince prospective local customers of the type's capabilities.

According to the Yakutsk airport administration, it has held talks to that effect with the manufacturer's representatives.

"They said the systems and engines on the Q400 are designed to remain operational at temperatures as low as minus 54C," says an airport spokesman.

"But under our regulations, the airframer is requested to submit particular test results to extend the type's operating temperature range after certification."

Cold-soak trials of the Q400 on local routes are scheduled for December, he adds: "Bombardier wants to use, for the tests, the same aircraft which was recently showcased here,"

Yakutia Airlines managing director Ivan Prostit says: "Of course, we'd like to acquire these aircraft. But first we need to study and evaluate them as thoroughly as possible."

Russian authorities granted certification for the turboprop in June.
