In the Professional training world these records are made available for sponsors to inspect when conducting training reviews as well as instructors and training management however I've never heard of a student (PPL/CPL or otherwise) who has not also had access to their training records students countersigning the report after completion is not only a UK 'gold plating' thing - it's practiced at several other schools across the EU that I know of. Could it be perhaps that there's nothing infact written down which is why the records are being withheld?
