Overview

Remove note regarding refueling into hydrant systems

Description of Proposed Changes

2.1.8. Defueled Product

Product defueled from an aircraft for purposes other than contamination shall be returned to the airline from which it was removed. Defueled product shall not be delivered to another airline’s aircraft without their approval. Defueling aircraft directly into joint use fueling systems is not permitted ~~authorized unless all system users have unanimously approved a joint use procedure~~. A meter or filter by-pass line is not an acceptable design, irrespective of any valve isolation arrangement. An existing non-compliant vehicle used to provide defueling for the airline shall be modified to meet this requirement.

After defueling, and prior to uploading the defueled product, allow the fueling vehicle to settle for 10 minutes then drain at least one gallon of fuel from the tank sump(s) into a suitable container and perform a visual inspection.

Remove unit from service if unable to obtain clean, dry fuel after three samples have been drained.

For other recommended practices, see [EI 1545] Recommended practices for the defuelling of aircraft.

Reason for Change

This sentence was necessary when TPA was still defueling into the hydrant but this is no longer happening so we should be clear that defueling into a hydrant or joint system is simply not permitted full stop.
