End of lease solutions

When returning a leased aircraft it’s important to have the support of an organisation that can help make sure the aircraft is returned in good condition whilst remaining safe and compliant, to ensure the aircraft retains its value. We provide various modification services to make this happen such as:

  • Temporary registration markings
  • Livery and paint modifications
  • Placards, decals & data plates
  • Seat covers
  • Carpet replacement
  • Wifi T-PED approvals
  • LF-ULD installations
  • AED modifications
  • ELT modifications
  • Cabin configurations
  • SELCAL code changes


Gama’s in-house Part 21G Production capability allows us to manufacture, procure and produce kits of parts needed for the successful modification of your aircraft. All parts will be released with either a Form 1 or Certificate of Conformity as a minimum.


Gama has the in-house capability to provide Part 21J Approved repair schemes for all structural elements. Our tailored repairs are a cost and time effective alternative to purchasing a repair scheme directly from the aircraft manufacturer.
