Within aircraft leasing the non-compliance on return or hand back can have severe and expensive implications; during a lease the operation of the aircraft is governed by airworthiness requirements and continued safety / compliance with the aviation authority requirements.
Following on from this then the end of lease will occur, and the aircraft is handed back to the lessor if it meets the lease return conditions – remember airworthiness compliance does not mean lease return compliance. The lease is about asset protection primarily and not airworthiness.
Considering this it means that for a lease return we need to prepare the aircraft and ensure compliance which will mean a thorough and complex review of the records.
