OPER. PSI 1Q92; o AEROQUIP FC321-06 UL 5/16 LP-GAS HOSE 350 MAX. OPER. PSI 2Q92; o AEROQUIP FC321-06 UL 5/16 LP-GAS HOSE 350 MAX. OPER. PSI 3Q92; o AEROQUIP FC321-06 UL 5/16 LP-GAS HOSE 350 MAX. OPER. PSI 4Q92; or o If hose identification is not legible. Compliance: Required as indicated after receipt of this AD, unless already accomplished. To prevent an uncontained fire in the balloon basket caused by a leaking fuel hose, accomplish the following: (a) Prior to further flight, remove each fuel hose fromthe leather sleeve, and, at system pressure, sniff test the entire length of the hose for signs of leakage. These signs could include frosting or chilling. (1) If any sign of fuel leakage is found, prior to further flight, replace the entire fuel hose/manifold assembly with an approved assembly that includes hoses with markings different than that specified in the Applicability section of this AD. (2) If no sign of fuel leakage is found, perform this fuel leakage test prior to each flight thereafter until the replacement required by paragraph (b) of this AD is accomplished. (b) Within the next 10 hours time-in-service after the effective date of this AD, unless already accomplished in accordance with paragraph (a)(1) of this AD, replace the entire fuel hose/manifold assembly with an approved assembly that includes hoses with markings different than that specified in the Applicability section of this AD. (c) Replacing the entire fuel hose/manifold assembly as required by either paragraph (a)(1) or (b) of this AD eliminates the repetitive test requirement of this AD.
