Narrative:
[Another maintenance personnel and myself] were assigned to aircraft X. After accomplishment of check on aircraft we read the [document] to be accomplished on the fan vibration of 8.8 No2 engine which referenced us to airbus 319 trouble shooting manual (tsm) 77-00-00-810-864. As a airframe rumble was reported we were able to proceed to step. It asked to specify if aircraft was in icing conditions or not. [Maintenance was contacted] to get an answer at approximately XA00. Tech called dispatch who said the aircraft operated through a storm. He then told us to have our supervisor to contact [maintenance] for the answer if icing or not and have it put in the [document] for us to continue. A flight recorder download card was generated that night for the aircraft to download the flight recorder data. We did not get a answer on if the aircraft was icing or not by the end of our shift. The reference 77-00-00-810-864-a requires inspections of engine and borescope inspections. Type of borescope depends on if icing or not. Also due to the fact that the engine vibe was 8.8 a requirement of inspection is fluorescent penetrant inspection of the low pressure turbine active clearance control (lpt/acc) manifold. I do not believe any of these items other than fan balance was done to the aircraft in question. I tried to verify by having my shop stewards pull up the records they were unsuccessful.
