Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
Evidence shows co-pilot called, 'mayday, uncontrolled spin' after acft radar track showed decel from 180 to 120 KTS over 2 min period while maintaining constant 4000 ft crz alt. Constant alt consistent with autopilot/autotrim use, particularly in view of reported turbulence/icing. Elev trim found at approx 13 deg nose up. No evidence found of preimpact failure or malfunction in acft pwrplants, structure or systems. Evidence suggests scenario of crew inattention after pwr reduction with autopilot altitude setting. On pwr application, acft pitched up from slow speed into uncontrolled flight. Duty day at time of mishap approaching 11 hours.
