Hot air balloon fuel tanks must replace a part, not just inspect it

US aviation regulators now require hot air balloon operators to replace a specific part on their fuel cylinders, rather than just repeatedly checking it for cracks. This means a permanent fix for a known safety issue, ending the cycle of inspections for affected fuel cylinders.

For years, hot air balloon operators with certain fuel cylinders had to keep checking a pressure relief valve adaptor for cracks. This new rule means they must install a redesigned part. This change removes a recurring maintenance task and a potential failure point, making operations safer and simpler for affected balloon owners.
