PART I of this bulletin consists of the replacement of AOA Sensor PN C-100117-2 with a

new unit PN C-100117-3 and the rework of the cover plate.

To do this, it is necessary, remove the Left-Hand (LH) and Right-Hand (RH) AOA sensor,

rework the AOA sensor cover and change the AOA sensor, from PN C-100117-2 to PN

C-100117-3.

PART II INSPECTION OF THE AOA SENSOR, AND SEALANT APPLYING - ADDITIONAL ACTION

PART II of this bulletin is an additional action to inspect and apply sealant on the interface

between the AOA covers and the AOA sensors, if necessary.
