According to Canandaigua Fire Chief Mark Marentette, a Bombardier Dash 8 twin turboprop was enroute from Newark, N.J., to the Rochester International Airport when smoke began filling the cockpit a little after 2 p.m. today.

A commercial plane with 37 passengers and three crew members aboard was forced to make an emergency landing Sunday afternoon when smoke filled the cockpit and passenger cabin, authorities said.

According to Ontario County sheriff’s deputies and Canandaigua Fire Chief Mark Marentette, a Bombardier Dash 8 twin turboprop operated by Commutair as a United Express Airway, was enroute from Newark, N.J., to the Rochester International Airport when smoke began filling the cockpit a little after 2 p.m.

A flight attendant also saw smoke in the plane’s bathroom. As a precautionary measure, said Marentette, the attending emptied two fire extinguishers in the bathroom and closed the door, said authorities.

The plane was 10 miles out of Canandaigua when the pilot requested an emergency landing at Canandaigua Airport, 2480 Brickyard Road, where emergency crews from Canandaigua, Victor and East Bloomfield responded, with Canandaigua on the scene within three minutes of the call.

No fire was found, said authorities.

“He (the pilot) had to put it on the ground right away,” said Marentette. “It (the landing) went great,” he said. “The crew did an excellent job.”

By the time they arrived, the pilot had already landed the plane without incident, and all emergency doors were open and passengers out, he said. Canandaigua Emergency Squad members responded to the airport and determined passengers and crew members were fine.

Original plans were for the passengers to board another plane and head to Rochester, he said, but that was scrapped in favor of auto. Some were picked in Canandaigua, while others were taken on to Rochester, he said.

Federal Aviation Administration officials were on the scene on Sunday to determine a cause of the smoke. It appeared it may be electrical in nature, said Marentette.

The chief noted that had the Canandaigua Airport not undergone its recent expansion, it’s unlikely the aircraft could have landed there. The plane might have had to land at Penn Yan’s airport, he said.

Canandaigua crews have been undergoing training for just such incidents, he said.
