I can begin.
From our perspective, we do use an external service provider for our main inspection program. Every single aircraft, once it returns, is inspected by our own maintenance team. Whenever issues are discovered as a result of the inspection, we follow up directly with the service provider. They have to provide specific corrective measures and put in place the quality program that's required to ensure the quality of their work.
We also have our own presence there on the ground to monitor the activities. We have periodic meetings with the management of this organization to review the record of incidents that are documented, and we follow up with them very closely to ensure that they put in place effective corrective measures.
