On 22 February 2012, the crew of an Air Contractors ATR 42 making a radar-vectored ILS approach to runway 23 at Glasgow at night allowed the airspeed of the aircraft to reduce and a stall warning followed. Corrective action then led to an overspeed and further corrective action almost led to a second stall warning. The Investigation concluded that SOPs were not followed, monitoring was ineffective and crew cooperation during recovery was poor. It was considered that crew performance may have been affected by inadequate rest prior to a night flying duty period.
