I would imagine that if QF ever send their aircraft to that facility then they will have a very large oversight team attending as well. The main role of the oversight team is to ensure a quality product.
The QANTAS "oversight team" generally comprises 2 teams consisting of a production plannner, a materials/logistics representative, an avionic and mechanical LAME, a team leader and sometimes a representative from quality assurance. Apologies if I've forgotten someone... Working a day and afternoon roster aligning with a particular shift or LAME from the MRO.
The traditional QANTAS heavy maintenance facilities of Sydney and Melbourne Tulla, where a LAME is available to carry out, supervise and certify that each individual task has been performed correctly, ensures a high quality product. In stark contrast to LTP and similar MRO's, where 1 Mechanical and 1 Avionic LAME on each shift certify for every task carried out by MRO staff during the check, with minimal input or supervision, if any, due to the volume of work carried out each day.
The role of the QF LAME's as part of the "oversight team" is to determine defect rectification and repair processes, with the tasks physically performed by MRO staff and certified for by their LAME. In conjunction with the materials/logistics representative, QF LAMEs organise the arrival of required spares, and "vet" all completed task cards. The quality of the inspections and other scheduled maintenance tasks completed are the responsibility of the certifying LAME employed by the MRO.
Every MRO is operated as a business and they will shortchange you at every turn if you allow them. It can turn decidedly nasty at times, especially if you are on your own and against a team.
In my experience, the costs associated with the "check" only, have been predetermined, with defects found during functional tests and visual inspections billed on an adhoc basis. A reluctance to document and rectify defects, incorporate mods or carry out AD's due to the associated increase in hangar time, in turn complicating the arrival schedule of the next customers aircraft appears to be the norm. Which is why our aircraft return home with so many deferred items, costs then worn by QF engineering.
