Do I lose my BiA bonus if a crew member gets knocked out?

In WoT, the Brothers-In-Arms crew perk gives all crew members in your tank a 5% skill bonus, but only if it is trained to 100% on all of them.

If a crew member is knocked out in a battle and I don't use a first aid kit to revive them, does the rest of the crew lose that 5% bonus for the rest of the battle? I know that when the Commander is knocked out, the rest of the crew loses their 10% Commander bonus, but does the same apply to the BiA perk?

Thanks!
