Common use of Replacement Engines Clause in Contracts

Replacement Engines. Lessee shall be entitled (subject to Clause 13.3), so long as no Default shall have occurred and be continuing, to install any engine on the Airframe or any part on the Airframe or any Engine by way of substitution, replacement, renewal or mandatory modification (notwithstanding that such installation is not in accordance with Clause 13.3) in circumstances where: (i) there shall not have been available to Lessee at the time and in the place that such engine or other part was required to be installed on the Airframe or, as the case may be, any Engine, a substitute or replacement engine or part complying with the requirements of Clause 13.3; and (ii) it would have resulted in an unreasonable disruption of the operation of the Aircraft or the business of Lessee as an airline or would have grounded the Aircraft if Lessee had deferred such installation until such time as an engine or part complying with the requirements of Clause 13.3 became available for installation in the Aircraft. In the case of either (i) or (ii) above, as soon as practicable after installation of the same on the Airframe or, as the case may be, such Engine, Lessee shall remove any such engine or part not complying with the requirements of Clause 13.3 and replace or substitute the same with an engine or part complying with the requirements of Clause 13.3. If, notwithstanding the foregoing, any replacement engine or part is owned by Lessor such replacement engine or part and the Engine or the Part replaced thereby shall be and remain the property of Lessor. Lessee shall assist Lessor in all reasonable respects to preserve, store, overhaul or dispose of such replaced Parts, all as may be reasonably directed by Lessor.
