The material/GSE (Ground Support Equipment) leasing service includes three phases: leasing quotation, equipment delivery and return, and leasing fee settlement. In the leasing quotation phase, after the customer expresses their leasing intention, COMAC provides the customer with the leasing price. In the equipment delivery and return phase, once the customer issues a leasing order, COMAC delivers the required equipment in accordance with the order and the terms of the agreement. After use, the customer returns the equipment to COMAC. In the leasing fee settlement phase, both parties verify the leasing fees based on the agreement terms and order, and complete the settlement. If the customer wishes to convert the leased equipment into owned equipment, they can choose to lease-to-own, changing the business model through an order modification. Customers can submit their requests via email or the e-commerce platform, and COMAC will respond upon receiving the request. The service includes providing the required material/GSE for lease to the customer. The goal is to provide qualified material/GSE. The customer benefits from quickly and efficiently obtaining the required material/GSE.
