No, I don't think it's a cover up. I became aware of the problem some years ago, when I wasn't even flying the type. When I went to fly the 109 it was the first thing I asked the engineers about! You obviously haven't been made aware of:
Agusta BT 109EP-86
Agusta BT 109S -19
Issued by the factory. Both refer to mandatory action with regards to marking the scissor link components to aid correct re-installation.
