Hot Air Balloons
AD/BAL/14 Fast Flow Restrictor Valves 11/95 DM
All hot air balloons.
Inspect LP gas cylinders for fitment of fast flow restrictor valves and remove if fitted.
Inspection of LP cylinders for fitment of restrictor valves may be accomplished by an AS2337- approved gas cylinder test station or by an operational check of each cylinder, with burner alight.
Before further flight. Thereafter, following any maintenance, or inspection for date stamping.
There have been cases reported of fast flow restrictor valves being fitted internally to LP gas cylinders during maintenance. Because a balloon burner uses fuel within the operating range of the fast flow restrictor valve, a serious accident could result.
