During the Period leading up to the actual aircraft redelivery, it becomes apparent quite quickly that the condition of the aircraft technical records, including the continuing airworthiness technical records, gain in importance as it is understood that any shortfalls can cost money due to the potential for significant compensation.

The Aircraft redelivery process often throws up anomalies which may become both contentious (means disputed) as well as extremely costly managing the aircraft records in the most diligent way will ensure you are in the best possible position during aircraft return.

Typical Redelivery Challenges Related to Technical Records

a) Late returning aircraft can be due to any number of problems or issues including those directly connected with technical records.

b) Some leasing contracts require the lessee to ensure that components installed on the aircraft do not exceed (or only slightly exceed) the age of the airframe.

Note – It is quite possible the 145-maintenance organisation is not aware of this (Component age) requirement and will fit as a matter of expediency any serviceable & regulatory compliant component. (Unfortunately, the subsequent replacement of such components can be very costly and time-consuming)

c) When mature aircraft have been through several ownerships the aircraft records can become voluminous with many documents which are essential “not required” by regulation, nevertheless “Filling the Technical Records Coffers” and in some cases even clouding the true picture.

d) Conflicting Record Retention with lessor obligations related to ambiguities between Continuous Airworthiness Management Organisation (CAMO) current status when compared with work packages, Airframe, Engine, APU & Aircraft Technical Logbooks as well as various shop visit reports.

e) To scan or not to scan? Because there is no scanning standard it falls to the operators to choose whether to scan documents in their own way or not.

If this scanning system is not “stand-alone” in its integrity (means it only functions within the Operators MRO Software) then it will not serve and “Value-Driven” purpose during the aircraft redelivery. The worst case would require resorting & rescanning leading to costly delays

f) Modification Management. The need to ensure detailed technical records of the status of any Supplemental Type Certificate Modifications (STC’s) as well as Cabin Interior Modifications, Avionic Modifications this information will support any required return to original configurations.
