The NTSB wants the FAA to attend immediately to “deficiencies” in the cold-weather operating procedures for Saab 340s, as well as the aircraft’s performance in icing conditions. Specifically, the Board recommends that Saab 340 pilots maintain a minimum operating airspeed of 1.45 Vs before known or forecast icing conditions and during icing encounters. It also suggests that the Saab 340 be fitted with ice-detection systems and have modified stall-protection logic. Finally, it asked the FAA to require all turboprop pilots to disengage the autopilot during icing conditions except during intermittent periods of high workload.
