The MX in CGK didn't suspect the newly replaced vane to be the caused.
The MX from the previous sector in DPS had suspected the CAPT's AOA vane had been the culprit, so he replaced that L Vane. Yet on its next flight, the SAME problem occured again with even more "flavors". Therefore, the MX in CGK surmised the AOA vane wasn't the problem - the problem must've lied elsewhere. He instead flushed the pitot and fixed other stuff which he thought to be correlated with what the CAPT wrote on the AFML.
