CAA and the previous operator should contact his local CAA to issue the export airworthiness certificate.

Date of engines run test
Engines run test can be done before or after the demonstration flight, preferred would be to accomplish
before the demonstration flight. It’s not as critical as the scheduling of the engines borescope inspection
●
Date of engines and APU(if applicable) borescope inspections
It is very important that borescope inspection is done after the demonstration flight, to guarantee, that no
damage has occurred before the first flight of Lessee after delivery.
3.2.3 Delivery Maintenance Check
During the maintenance (delivery) check, the Lessee delivery team should make sure that:
●
●

The documentation of the maintenance status of the aircraft and relevant technical records correspond
to delivery conditions stated in the lease agreement.
The physical technical condition of aircraft corresponds to delivery conditions. It’s suggested, to engage
very experienced base (heavy) maintenance inspectors, who are familiar with the aircraft type, and can
find and determine any deviations at the inspected zones, based on approved data. All findings should be
listed in detail and sent to Lessor for rectification.
It is advised to take photographs of all relevant sections as reference material during the lease, and for
aircraft redelivery.
The content of a physical inspection will be different for each aircraft type, but a generic template is
included in Annex I.
If allowed under the lease agreement, the Lessee should witness the functional and operational checks which
are completed at the end of the delivery check just before the CRS is signed and issued. When Lessee has
verified and confirmed that the technical condition of the aircraft satisfies the delivery conditions, at this
stage, Lessor may start preparation for the demonstration flight.
During the physical inspection, the Lessee should ensure that both the physical condition and the actual
aircraft state in relation to the records (installed components, aircraft configuration etc.) are acceptable. The
physical inspection should ideally cover a full survey of the aircraft.
3.2.4 Records Acceptance
Depending on the age of the aircraft, the review of the aircraft records can be a labor-intensive activity. The
records review should ideally be performed by experienced airworthiness staff, to ensure records meet the
level that is internally accepted by the Lessee and specified in the lease agreement. This records compliance
check is similar to the checklist for redelivery. A generic list can be found in Annex II, while an overview of a
