AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Revise the airplane flight manual to provide procedures and limitations for operating with out-of-tolerance AOA transducers. Measure the vane angles and voltage of the AOA transducers. Rework the AOA transducer assemblies and measure the baseline resistance. Perform repetitive measurements of the resistance of both AOA transducers. Inspect the left- and right-side AOA vane decals.
