What the agency says
The FAA is adopting a new airworthiness directive (AD) for Cameron Balloons Ltd. (Cameron) fuel cylinders fitted with certain pressure relief valve (PRV) adaptors on hot air balloons. This AD was prompted by the discovery of cracks on the upper hex portion of PRV adaptors. This AD requires repetitively visually checking the PRV adaptor for cracks and removing any fuel cylinder with a cracked PRV adaptor from service. The FAA is issuing this AD to address the unsafe condition on these products.
