End of lease adjustments serve what purpose regarding maintenance?

The purpose of end-of-lease adjustments is fundamentally about ensuring that the aircraft is returned to the lessor in a condition that aligns with the stipulated terms of the lease agreement. This aspect is crucial because it helps maintain the value of the leased asset and ensures that the lessor does not incur unexpected expenses related to repairs or refurbishments after the aircraft has been returned. By having this adjustment mechanism in place, both the lessee and lessor have clear expectations regarding the condition of the aircraft at the end of the lease term. This promotes accountability on the part of the lessee to maintain the aircraft properly throughout the lease period, thereby protecting the interests of the lessor and facilitating a smoother transition at the end of the lease.
