If you are currently undertaking training, have a chat to your CFI/HOO. If you previously held a PPL, you would be able to get the minimum hours for the licence at the time credited. The CFI/HOO may be able to certify additional hours on any other evidence that you have i.e. receipts etc, provided he/she can satisfy themselves, and is prepared to accept responsibility for their determination.
Alternatively, you may be able to contact
[email protected] and see if your old PPL test form can be retrieved. That would have a summary of your hours at the flight test stage, and would probably result in you retaining more hours, as with most candidates, you probably had more than the minimums at test time.
Cheers. GB
