Guidance Material for aircraft leasing Guidance Material for aircraft leasing
Guidance Material and Best Practices for Aircraft Leasestypical delivery book can be found in Annex III. During the records review and acceptance there are variousitems which require additional attention:●●●Maintenance program compliance reviewVerify the status of each maintenance task to:oDetermine no tasks are overdue and the aircraft falls within the agreed maintenance clearanceperiod.o Verify the status and/or existence of a sampling program 11 .oConfirm that repeat inspections of repairs and additional tasks linked to modifications (Instructionsfor Continued Airworthiness (ICA)) are included.In particular, the Lessee should be aware of recently included maintenance tasks and their related“grace” period, which are the result of new Maintenance Planning Document (MPD) or MaintenanceReview Board Report (MRBR) revisions. Additionally the Lessee should verify that the status and findingsresulting from the Corrosion Protection and Control Program (CPCP) are readily available (e.g. level,follow up, etc.). Please refer to Annex VII for guidelines regarding the AMP.Airworthiness DirectivesReview of the AD status and AD dirty fingerprints for correct compliance (including review of anyAlternate Means of Compliance (AMOC), to verify transferability). AMOCs are not always transferablebetween operators, and should therefore be avoided. Often, AMOC’s are prohibited by the leaseagreement redelivery conditions. In this case, transferable means that in order for the AMOC to be valid,there is no company-specific tool or procedure required that is not available to next Lessee.Some ADs are applicable to a specific part number or serial number (range). Particular attention shouldbe paid to these AD as very often these parts may have been replaced and/or the dirty fingerprint maynot accurately reflect the inspected part. Please refer to Annex VIII for guidelines regarding ADs.Modifications and alterationsA review of the dirty fingerprints and engineering data is needed for all major and minor modifications. Ofparticular importance are major modifications such as Supplemental Type Certificates (STC). It is of theutmost importance to ensure that all non-proprietary STC data is available, including the relevant manualsupplements. The data package should include a “Right to use” letter, the engineering drawings andcertification basis (local, Pre-EASA, EASA, FAA, other), as well as any dirty fingerprints to see if any insituchanges were applied. Specific attention should be paid to the associated manual supplements (e.g.correct integration into the AMM, Illustrated Parts Catalogue (IPC), Wire Diagram Manual (WDM), etc.) toensure correct implementation of any additional inspection requirements into the maintenance program.Please refer to Annex VI: Modifications Guidelines for guidelines regarding Modifications.●Repair fileA review of the dirty fingerprints and certifications of each individual repair should be performed,including a mapping of the aircraft. Compliance data should include a correct reference to the SRM used,Non-Destructive Testing (NDT) task-cards, communication with manufacturer, and engineering datasuch as drawings, damage overviews, and thickness specifications. The SRM revision is particularly11Annex VII 3.326 4 th Edition 2017
Deliveryimportant, as the continuous development and subsequent issue of newer SRM revisions may introducenew and more stringent repair procedures. Please refer to Annex V.●HT components and On Condition/Condition Monitoring (OC/CM) componentsThe Lessee should verify availability of the correct release certificate, as well as compliance with themaintenance clearance period for each (HT) component. Items such as emergency slides should becarefully inspected, as these have sub-assemblies (e.g. batteries, squibs etc.) which are required to belisted separately on the release certificate. Please refer to Annex IX for guidelines regarding components.●Regulatory certificatesThe Lessee should perform a review of the different certificates and statements, such as the CoA, CoR,Certificate of Insurance, Noise Certificate, etc.●LogbooksThe Lessee should verify that all logbooks are available, updated, and closed. It is important to note thatnot all authorities require the use of hardcopy logbooks. Should such a requirement be applicable to aLessee, it is of vital importance to verify that logbooks are available for the entire life of the aircraft. If theyare not available, dispensation should be arranged with the authorities prior to importation.●EnginesAs engines are high value components and individual maintenance events are extremely costly, specialattention should be paid to the documentation associated with engines. During the review of the enginerecords, the Lessee should ensure that all documentation required to determine the engine’s remaininglife and expected operational limitations is available (shop visit reports, trend data, borescope reportsetc.). Subsequently, the BtB documentation for LLPs should be carefully reviewed.●Interior burn certificationThe Lessee should verify that burn certification is available for cabin, flight attendant, and flight crew;seat covers, cushions, sidewalls, carpets, hat racks, and curtains. This requirement can be satisfied byeither confirming that an official test report and approval are available, or that these components arelisted in the IPC. Subsequently, the Lessee should perform a physical check to determine whether thecorrect parts numbers are installed.3.2.5 Demo Flight/BorescopeThe demonstration flight program should be agreed by Lessor and Lessee before the demonstration flight,because the programs used for the demonstration flight can be very different. As example, the previousoperator’s demonstration flight program can be used, the new Lessee’s flight program can be used, or Lessorcan use aircraft manufacturer’s demonstration flight program. The demonstration flight should be organizedby the Lessee. During the demonstration, Lessee’s representatives should observe operation of the systemsin the cockpit and in the cabin. Aircraft’s water tanks should be filled up with water for testing the watersystem and lavatories during the flight. After the demonstration flight both parties, Lessor and Lessee shouldorganize a de-briefing, which includes the pilots and Lessor’s mandated parties, where they can mutually4 th Edition 2017 27

typical delivery book can be found in Annex III. During the records review and acceptance there are various
items which require additional attention:
●

Maintenance program compliance review
Verify the status of each maintenance task to:
o
Determine no tasks are overdue and the aircraft falls within the agreed maintenance clearance
period.
o Verify the status and/or existence of a sampling program 11 .
o
Confirm that repeat inspections of repairs and additional tasks linked to modifications (Instructions
for Continued Airworthiness (ICA)) are included.
In particular, the Lessee should be aware of recently included maintenance tasks and their related
“grace” period, which are the result of new Maintenance Planning Document (MPD) or Maintenance
Review Board Report (MRBR) revisions. Additionally the Lessee should verify that the status and findings
resulting from the Corrosion Protection and Control Program (CPCP) are readily available (e.g. level,
follow up, etc.). Please refer to Annex VII for guidelines regarding the AMP.
Airworthiness Directives
Review of the AD status and AD dirty fingerprints for correct compliance (including review of any
Alternate Means of Compliance (AMOC), to verify transferability). AMOCs are not always transferable
between operators, and should therefore be avoided. Often, AMOC’s are prohibited by the lease
agreement redelivery conditions. In this case, transferable means that in order for the AMOC to be valid,
there is no company-specific tool or procedure required that is not available to next Lessee.
Some ADs are applicable to a specific part number or serial number (range). Particular attention should
be paid to these AD as very often these parts may have been replaced and/or the dirty fingerprint may
not accurately reflect the inspected part. Please refer to Annex VIII for guidelines regarding ADs.
Modifications and alterations
A review of the dirty fingerprints and engineering data is needed for all major and minor modifications. Of
particular importance are major modifications such as Supplemental Type Certificates (STC). It is of the
utmost importance to ensure that all non-proprietary STC data is available, including the relevant manual
supplements. The data package should include a “Right to use” letter, the engineering drawings and
certification basis (local, Pre-EASA, EASA, FAA, other), as well as any dirty fingerprints to see if any insitu
changes were applied. Specific attention should be paid to the associated manual supplements (e.g.
correct integration into the AMM, Illustrated Parts Catalogue (IPC), Wire Diagram Manual (WDM), etc.) to
ensure correct implementation of any additional inspection requirements into the maintenance program.
Please refer to Annex VI: Modifications Guidelines for guidelines regarding Modifications.

Repair file
A review of the dirty fingerprints and certifications of each individual repair should be performed,
including a mapping of the aircraft. Compliance data should include a correct reference to the SRM used,
Non-Destructive Testing (NDT) task-cards, communication with manufacturer, and engineering data
such as drawings, damage overviews, and thickness specifications. The SRM revision is particularly
