For me it was '99 or '00. I was with Cessna's Anchorage dealer. If I had to guess at my memory, we were at about -28Ëš because I think I remember the story that Boeing didn't certify their airplanes to work at -30Ëš. We got the 172 Skyhawk started (barely) and once we got above about 1500 feet we warmed up. The dealer got to file for and get paid to install new wingtips because they cracked.
Very cold weather isn’t kind to airplanes, especially small aircraft.
