Information For Operators (InFO) Document Says Sensors Can Be Damaged During Normal Operations

The FAA last week issued an InFO (Information For Operators) warning of the potential for AOA sensors to be damaged during the course of normal operations and subsequently malfunction.

According to the FAA, based on continued airworthiness activity on multiple foreign and domestic products, including large transport aircraft as well as small general aviation aircraft, the FAA has determined it is necessary to advise operators of the importance of performing proper operations and maintenance on AOA sensors.

There are multiple entities involved with the operation and maintenance of aircraft, such as aircraft operators, certificate holders, maintenance providers, ramp service providers and miscellaneous service providers. Regardless of certification basis, it is imperative that all operators are aware of the criticality of AOA sensors and the potential for damage during normal operations, maintenance procedures, servicing procedures, and any other procedures around an aircraft where damage to an AOA sensor could occur. Operators can find the requirement of maintaining these components in the instructions for continued airworthiness (ICA).

The FAA recommends that all personnel as identified in the InFO should review current procedures identified in their appropriate operational, maintenance, or servicing manuals. The review should ensure that the manual adequately identifies all aspects and appropriate policies/procedures around AOA sensors.
