Compliance required as indicated, unless already accomplished.
To prevent failure of the fuel line, P/N AB15-835, which connects the low pressure fuel filter to the auxiliary power unit, accomplish the following:
(a) Within 75 hours' time in service after the effective date of this AD and thereafter at intervals not to exceed 75 hours' time in service from the last inspection, inspect fuel line, P/N AB15-835, which connects the low pressure filter to the auxiliary power unit, for signs of fuel leakage, in accordance with BAC 1-11 Alert Service Bulletin 49-A-PM 3579, Issue 1 or later ARB-approved issue or FAA-approved equivalent.
(b) If the fuel line, P/N AB15-835, is found to be leaking fuel during the inspection required by paragraph (a), before the next flight, replace the defective fuel line with a serviceable part of the same part of the same part number or with a modified fuel line, P/N AB15-967, or improved P/N AB15-835 manufactured by the Dunlop Company.
(c) The repetitive inspections required by paragraph (a) of this AD may be discontinued after the modified fuel line, P/N AB15-967, or improved P/N AB15-835 manufactured by the Dunlop Company, is installed. When the latter fuel line is installed, it should be renumbered as P/N AB15-967.
This amendment becomes effective September 19, 1968.
