loaner

Airline operators often have the same problem:

Their spare part is no longer functional! What to do?

You could wait for a repair of that unit which leads to a longer downtime of your aircraft.
You could also buy an exchange unit, which means your unit will be sent back as a core. As a consequence thereof you will lose your serial number and possible flight data (TSN/CSN) of that unit.

The loan of a single component provides customers with full traceability. In case of a loan request, Aviation Assistance provides the customer with a component and expects the customer to return the component to Aviation Assistance after use.
