An aircraft lease can be a complex event when dealing with the multiple tasks and considerations regarding the return conditions as defined in a lease agreement.
The emergency equipment list or EEL is an important document onboard an aircraft during service, but also very important during a lease transition or review.
During a lease transition or during a period when an aircraft may be stored by a lessor / airline there may be a time that flight is required, and the aircraft is not currently meeting the airworthiness requirements.
