Line Certifying Techinians refers to the engineers that check and sign off aircraft maintenance for your Ryan Air 737 at that gate of Glasgow airport etc. The controlling document for maintenance is the aircrafts tech log. they will run a team to do the daily pre flight check, the sector turnround checks, any Minimum Equipment List / Despatch Defect List entries limiting unservicable equipment that the aircraft can still operate without or replacing them between flights (why your aircraft is delayed on your holiday), replenishments, post operation rectification and any scheduled maintenance required on that line stations fleet of aircraft and any other aircraft that the station has responsibly for. The work will be shift, with possible overtime and trips away to recover AOG from other locations. The pay corresponds this high tempo / high responsibly position. The more type ratings the guy has for the various aircraft found in a fleet will increase his pay. All certifying techs have a type rating, because they wouldn't be certifying without one legally.
Base Certifying staff work at Maintenance Repair and Overhaul facilities (MRO), certifying work on aircraft that are under heavier scheduled maintenance or modification programmes. The tempo of work is less, thus pay reflects this too. Shift work pays more and overtime is not uncommon too.
