Hi Westhawk,
This is the avenue that we originally looked down also and in my corospondence so far with CASA I asked if there was a way we could apply for a dispensation or concession to allow us to use our aircraft for the photography role. The reply was that after speaking with the Airworthiness and Engineering branch there would be no concessions or dispensations forthcoming and that we will need to obtain an aircraft that is approved for the purpose under the existing rules.
Obtaining another aeroplane is rather cost prohibitive, so I am now trying to get a clear picture of why this rule (CAR262APA) need apply to our aircraft or if there are ways for us to avoid it (for example, if our aircraft was reclassified as Normal category rather than ULA).
