The NTSB believes currently required stall-warning systems are not adequate to cover all critically low-airspeed conditions and has recommended that the FAA require the installation of so-called “low-airspeed alert” systems on all airplanes used in FAR Parts 121 and 135 commercial operations.

The Safety Board's recommendation stems from its investigation into several Part 121 and Part 135 accidents since 1982 (most recently the crash of a King Air that killed the two pilots and six passengers, including Sen. Paul Wellstone [D-Minn.]) in which “a stall or failure to maintain airspeed during the approach or landing phases was cited as a causal or contributing factor and in which icing was not cited as a factor.”
