Airbus aircraft SRM clearly state that any damage to an existing repair must be referred to Airbus to get a new repair scheme. Removal of repair and reperforming as per SRM is not allowed unless Airbus says it.
I did not find any such instructions in the BNG SRM. As a precaution, we do normally follow the same procedure, but this does add a huge cost factor since all these Tech Support Requests are chargeable in USD.
How do you guys do it ? This is a huge problem for us especially in repairs on the cargo doors and aft of the L2 door due to GSE contacts.
