Unsafe Condition
The heating capability of several AOA [angle of attack] transducer heating elements removed from in-service aircraft has been found to be below the minimum requirement. Also, it was discovered that a large number of AOA transducers repaired in an approved maintenance facility were not calibrated accurately.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Inspect the AOA transducers for degraded heating elements and inaccurate calibration. Replace any AOA transducers found to have degraded heating elements or inaccurate calibration. Revise the AFM to include the new inspection and replacement procedures.
