Unsafe Condition
An uncontained fire in the balloon basket caused by a leaking fuel hose identified with AEROQUIP FC321-06 UL 5/16 LP-GAS HOSE 350 MAX. OPER. PSI markings 1Q92, 2Q92, 3Q92, 4Q92, or hoses with illegible identification.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Prior to further flight, remove each fuel hose from the leather sleeve and sniff test at system pressure for leakage signs like frosting or chilling. If leakage is found, replace the entire fuel hose/manifold assembly with an approved assembly using hoses with different markings. If no leakage is found, repeat the test before each subsequent flight until replacement within 10 hours time-in-service after the AD's effective date. The replacement must use hoses with markings different from those listed in the Applicability section.
