In the beginning, let's understand the term "Aircraft records".
Aircraft records - the documents that include information about aircraft, its special features, fitted equipment and show what maintenance/modification has been carried out on the aircraft, engines, propellers (if installed) and its equipment.
ICAO says that all maintenance or any action that can be considered as aircraft maintenance should be recorded in the aircraft logbook or in the logbook of the aircraft part on which this maintenance has been carried out.
Example: Calendar inspection has been carried out on the airframe. This inspection and all details related to this inspection should be recorded in the logbook as a short record with reference to the work package. The work package become is a dependable part of the airframe logbook due to he explains in details what exactly has been checked, repaired or replacement during a particular calendar inspection.
In my work, meet the situations when the short record is made in the airframe logbook about maintenance, but the work package is missed or not full (form 1 for parts are missed; certificate of conformity is missed; work card is not presented for the task which was declared in CRS; etc.). Such condition says the aircraft records are not full and forced to reduce the aircraft price (value).
Question: What shall we do to improve such a situation?
Answer: We have to recover the missed document. For this, we can use several ways which are useful: a/ connect with MRO who does maintenance and ask TRUE COPY FROM original; b/ask MRO if they have such missed document in electronic format and print out the record by marking "COPY FROM eFORMAT DUE TO MISSED ORIGINAL"; c/ redone the work, or replace, recertify the part which doesn't have Form 1.
All this activity allows for recovering the missed documents, but it is too late when you are selling the aircraft.
