Unsafe Condition
Incorrect removal of machining oil during the manufacturing process of Thales Avionics Angle of Attack (AoA) resolvers can lead to oil residue between the stator and rotor parts of the AoA vane position resolvers. At low temperatures, this oil residue becomes viscous, causing delayed and/or reduced AoA vane movement, which can provide incorrect AoA indications.
