Unsafe Condition
Oil residue between the stator and rotor parts of the AoA vane position resolvers, due to incorrect cleaning of machining oil during manufacturing, becomes viscous at low temperatures, causing lag of AoA vane movement. This could lead to discrepant AoA measurement and, if not corrected, could result in late activation of angle of attack protection, potentially causing an unsafe condition during flight at high angle of attack.
