o
Profile for the flight should be recorded in the lease agreement or agreed in advance of the flight.
The flight is conducted to demonstrate aircraft and system functionality in normal operations and
should not exceed 2 hours in duration.
Subject to Lessee CAA, Lessor or Lessor representatives, which may be the next Lessee
representative, may be on board the aircraft to act as observers only, with one located in the cockpit
for the entire flight including take-off and landing.
In case any findings are recorded during flight or FDR analysis and the rectification of such findings
may be sufficiently demonstrated according to the AMM/TSM requirements a further demo flight
shall not be necessary.
Lessee should consider what defects/discrepancies might drive the requirement for repeat demo
flight, and how this is decided and by whom.

The Lessor or Lessors’ representatives usually have the option to witness these inspections.
The Lessee should ensure that the inspection is done I.A.W. the AMM, this should be in the lease
agreement.
It may be useful to contemplate the return of a temporary engine if the assigned engine does not
meet the return conditions.
Lessee and Lessor should schedule a meeting prior to the inspection to run through the details of the
inspection; video on/off, tooling etc.
The Lessee should ensure that the limits of acceptance and the definitions are clear in the lease
agreement, i.e. repeat inspection limits, on watch etc.
Lessee should consider the possibility of the Lessor accepting any manufacturer “one time
concessions” in relation to findings which are outside of the published limits, or where no limits exist,
and where the engine OEM has assessed the finding to have no reduced interval inspection
requirements and no impact on engine performance.
Final discrepancy list

o
Lessee and Lessor agree on the final discrepancy list and associated remedies.
Lessee should consider language in the lease agreement that facilitates return of the aircraft with
minor discrepancies.
