CASR 91.655(e) - Would mean that only aircraft capable of closed port (pressure) refueling would be permitted to conduct hot refueling.
This would have an adverse effect on the helicopter and Aerial Application industry as the majority have open port refueling systems.
The impact for the HEMS industry, is that most country airfields do not have pressure refueling and precludes drum stock refueling.
The cost to upgrade to closed port is expensive and as previously stated precludes country and airfields and drum refueling (used most often in natural disaster).
The risk could be reduced to ALARP by the Operations Manual or Exposition stating the maximum quantity that can on board for during hot refueling, which limits the possibility of overflowing the fuel tanks.
This proposal is not in line with FAA SAFO 10020.
CASR 91.125 does not cover the requirements of ICAO Annex 6 Part 1 Chp 6. Carriage of AOC & Opspec. Is this to be covered in CASR Part 119/121/135? As an Inspector currently conducting SAFA checks in a foreign country this is considered a finding .
