Frog Storm.... Might need some hunting up but Avdata have already had a loss in court, many years ago They took a non payer to court and the individual won.
The outcome was... By law Avdata ( or anyone else for that matter)..has to supply you with a TRUE and ACCURATE account. If it contains errors, that is THEIR problem. You MAY advise them of those errors but it is not your responsibility. That you receive a TRUE and PROPER account IS theirs.
In the past accounts have shown landings to and parking at places Ive never been..running into 100s of dollars in some cases.
So..carefully check those invoices !
When absent and the account unpaid, month by month they added
$50 p/m...so I get back to base and the 23 $ bill is now $223.!!
With a big red marker pen, a few terse words put a stop to that sh*t.
Anthill...dont let the horror stories put you off aviating. There are more councils that have seen the light these days, and smallies are free. Any landing charges levied were mostly lost to Avdata, with little benefit to the council anyway.
