Hi;

I need some information please ASAP. I understand drop tanks have to be bolted on permanently and made undroppable, but can someone steer me to the exact regulation or advisory that deals with this situation?

Area of concern is whether a drop tank installation on a P51 can involve a bolted on mount (release impossible in flight) BUT the mount made so that the tanks can be removed and replaced easily on the ground. In other words, does "bolted on" mean "BOLTED ON!!!"

Many thanks for your assistance.
