"Exchange Plus Cost" means an exchange in which the customer pays the exchange fee at the initial stage and subsequently pays the cost of the repair and overhaul of the off-unit.

In this mechanism, you get serviceable aircraft parts and return an unserviceable core at a later date. When you’re initiating an aircraft parts exchange, choose one of the two popular opinions; the exchange plus repair model and the flat rate exchange model. The key difference between the two is how you pay for the repair of your core return.

The two exchange options available for aircraft are the exchange plus repair model and the flat rate exchange model. In the exchange plus repair model, if components or aviation parts become faulty, operators can exchange the defective part for a refurbished/serviceable one from the aircraft parts manufacturer, a designated maintenance facility, or a third-party supplier. The flat rate exchange model manages aircraft parts and components. Here is a fixed flat rate for exchanging faulty aviation parts with serviceable ones.
