The Customer Service Agent at Rochester placed the flight documents on the operations office desk for the captain's signature. The weather documents reportedly included the 1600 Service A sequence report and the 1453 Mohawk weather message. Not included were the 1415 aviation severe weather forecast, the 1430 SIGMET, or the 1445 amended Rochester terminal forecast. These documents were available at United Air Lines. The failure to provide this weather information is contrary to the provisions of the Civil Air Regulations[1] in the dispatch of Flight 112 from Rochester.
