Wet Leasing is defined under EU regulations as an agreement between air carriers pursuant to which the aircraft is operated under the AOC of the Lessor.
Note: A Damp Lease is defined as a wet-leased aircraft that includes a cockpit crew but not cabin attendants.
Please note that there may be a charge associated with wet/damp leasing applications depending on how much assessment is required. See the details on Leasing Application Charges.
In the UK, wet/damp lease approvals can be considered up to a maximum of 14 months (seven months initially, with a possible extension for up to a further seven months).
Flight Time Limitation (FTL) Scheme
EU-OPS Subpart Q is not a complete scheme for FTL as it contains a number of areas that are still regulated by Member States and was not subject to scientific review. Therefore, in accordance with EU-OPS recitals and as required by Article 8(4) the CAA has notified the Commission that it will maintain CAP 371 as the basis for all UK AOC FTL schemes until such time as Community rules based on scientific knowledge and best practice are established. With regard to FTL scheme requirements for wet lease arrangements, they must be in compliance with the UK operator's approved FTL scheme.

Wet Lease-out of a UK registered aircraft on behalf of a foreign operator
Article 13(2) of Council Regulation (EC) No. 1008/2008 does not require lease approval. However, UK air carriers should inform their CAA Assigned Flight Operations Inspector of such leases, even if the operation is within the region currently authorised on their AOC.
