Apologies if I misinterpreted. I agree, the majority of aicraft IPTs (as opposed to equipment IPTs) are good at safety. The Design Authorities also keep them right and refuse contracts if the necessary safety clauses aren't there. My main beef would be when SEMs enter the equation. Too many major mods are now schemed as SEMs because of lack of funds.
But I concur with other posts highlighting the lack / dilution of experience. There are long standing safety procedures to follow and I find that equipment IPTs often completely ignore them. Worse, they are allowed to, even after BOIs or audits highlight it. That is a senior management failure.
