For want of storage.

Mechanics, any and every place on your AH-64A/D is not for storage.

All the gear you carry on your bird goes in certain areas. Your -10 TM tells you where to store gear like flight bags and pubs bags.

Check out the TM and put your stuff where it's authorized, like on the bottom shelf of the left aft equipment storage bay and the survival storage bay next to it.

Don't put stuff in the catwalk area and leave it. Though it's tempting, keep the pubs bag and other items away from the cockpit ECS air intake. If you block it, it will overload and burn out the motor tan. And reduced evaporator air flow can knock out the ECS system.

A broken ECS means no air to cool you down in the summer of the desert heat and no heat to keep you warm in the winter.

Don't stow gear wherever you please. Stowage space on an AH-64 is limited to the left aft equipment stowage bay and the survival equipment stowage bay. They are accessed from either side of the aircraft. In addition, the D model has two flyaway stowage bays: the CPG crew station and the pilot crew station.
