No need to inforce anything, just wait for the first incident. A bit of inquiry, which includes the FOB, and this is it...
A bit like operating a Falcon 900 EXy in Lfmd, it exceeds the authorized MTOM, but what is closer from a 900B than an 900EX ? even the fpl is the same icao designation... Just wait for anything to happen, the insurance company will love it, your licence as well..
