I am not sure if you are limiting your question to "rejection" of an application, or including loss of certification...
If the latter, the Azores glider incident resulted in a temporary loss of Air Transat's A330 ETOPS rating (and a downgrading of the entire remainder of the fleet).
The attached story contains a summary at the end; it refers to the fact that ETOPS authority was suspended immediately follwoing the incident (August 24) and partially restored on September 7. Full ETOPS rating was restored the follwoing May.
I wonder how much extra fuel AT
ended up buring because of that?
