Gol airlines in Brazil just reported 11 more. They have a fleet of 125 - many of them too new to have been inspected. Even in the unlikely event that they inspected everything, that’s 8.8%. So my guess is that the 5% number from today is significantly too low.
I can’t post links because this is my first post, but you can see the specific planes in the fleet if you search for Gol airlines on planespotters dot net. Their fleet looks like a roughly 80/20 mix of 737-800s and 700s.
