Guidance Material and Best Practices for Aircraft Leases
for a period of no more than (X) hours in total, and the flight costs (except the cost of Lessor’s
representatives) and fuel will be furnished by and at the expense of Lessee. A draft copy of
Lessee's approved flight test procedure will be furnished to Lessor upon written request or
otherwise no later than (X) months prior to the end of the lease term.
b) Lessee will give Lessor at least (X) calendar days’ notice of the date on which the Redelivery
Check Flight is scheduled to be performed, and Lessor or its representatives may attend the
Redelivery Check Flight. For the avoidance of doubt, if Lessor or its representatives fails to attend
the Redelivery Check Flight, then Lessee will perform the Redelivery Check Flight in the absence
of Lessor or its representatives. However, Lessee will provide Lessor with the findings and
observations of the crew recorded during the Redelivery Check Flight and will still be required to
correct any discrepancies identified during the performance of the Redelivery Check Flight. A
pre-flight briefing will be hosted by Lessee's authorized flight crew.
c) Provided that the Aircraft is in a condition acceptable to Lessee’s authorised flight crew for the
performance of the Redelivery Check Flight, it is not necessary for all Notified Discrepancies (of
the Aircraft and the Aircraft Documentation) to be rectified prior to operation of the Redelivery
Check Flight.
d) If the Aircraft is parked after a successful Redelivery Check Flight Lessee will procure that the
Aircraft is:
(i) maintained in accordance with the AMM and the Maintenance Programme until redelivery
or;
(ii) returned to a maintenance facility for rectification of Notified Discrepancies.
e) The inspection of the Aircraft airframe and avionics systems (which can only be determined to be
serviceable during the Redelivery Check Flight) will be deemed complete upon the completion of
a successful Redelivery Check Flight. The Redelivery Check Flight will be successfully completed
if there are no discrepancies (other than Acceptable Discrepancies) identified during such flight
or if all discrepancies (other than Acceptable Discrepancies) identified during such flight can be
corrected and verified on the ground without a further Redelivery Check Flight as provided in
Paragraph 2.9(f) below.
f) If requested by Lessor, a post-flight briefing will be hosted by Lessee's authorised flight crew.
Discrepancies from the parameters laid down in Lessee's approved flight test procedures
identified during the Redelivery Check Flight will be documented for rectification. If Lessee’s
authorised flight crew determines that it is possible to demonstrate that a discrepancy recorded
during the Redelivery Check Flight can be corrected and verified on the ground without the need
for a further Redelivery Check Flight, then Lessee will not be required to perform another
Redelivery Check Flight to demonstrate correction of that discrepancy.
2.10 Power Assurance Runs
a) If required by the Lease, Lessee will accomplish a maximum power assurance run on each
Engine in accordance with the AMM (XX-XX).
b) Lessee will give Lessor at least (X) calendar days’ notice of the date on which the maximum
power assurance runs are scheduled to be performed, and Lessor or its representatives may
attend the maximum power assurance runs. For the avoidance of doubt, if Lessor or its
