Plain English Summary

2/10 complexity

Requires inspection of LP gas cylinders on all hot air balloons and removal of any internally fitted fast-flow restrictor valves. Applies to owners, operators and maintenance personnel; compliance is required before further flight and after maintenance or inspection because burners operate within the restrictor's activation range and could create a serious accident.

AD/BAL/14 Fast Flow Restrictor Valves 11/95 DM

Applicability: All hot air balloons.

Requirement: Inspect LP gas cylinders for fitment of fast flow restrictor valves and remove if fitted.

Note: 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.

Compliance: Before further flight. Thereafter, following any maintenance, or inspection for date stamping.

Background: 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.
