76-24-06 R2 BRITISH AIRCRAFT CORPORATION: Amendment 39-2779 as amended by Amendment 39-2800 is further amended by Amendment 39-4734. Applies to BAC 1-11 200 and 400 series airplanes, certificated in all categories.

Compliance is required as indicated.

To detect oxygen leaks, due to fractures in the flexible oxygen hoses of the emergency oxygen system, and prevent possible in-flight fires, accomplish the following:

(a) Within the next 250 hours time in service after the effective date of this AD, unless already accomplished in the last 1500 hours time in service, conduct a leak test of the emergency oxygen system in accordance with paragraph 2.3 of the section entitled "Accomplishment Instructions" of British Aircraft Corporation Alert Service Bulletin 35-A-PM 5394, issue 3, dated June 29, 1979, or an FAA-approved equivalent.

(b) If, during the leak test required by paragraph (a) of this AD, a leak is found, before further flight, locate the source of the leak and replace the defective part with a new part of the same part number or with a serviceable FAA-approved part and then retest the emergency oxygen system in accordance with paragraph (a) of this AD.

(c) Inspect and rework the flexible hoses of the emergency oxygen system within the next 1000 hours time in service or six months after the effective date of this AD, whichever occurs sooner, unless already accomplished within the proceeding 1500 hours time in service, and thereafter at intervals not to exceed one year, in accordance with paragraph 2.4, Figure 1 through 3, and Table 1 of the service bulletin.

(d) If, during an inspection required by paragraph (c) of this AD, the flexible oxygen hoses are found fractured or embrittled, before further flight, replace the affected parts with new parts of the same part number or with serviceable FAA-approved parts and then retest the oxygen system for leaks in accordance with paragraph (a) of this AD.

Amendment 39-2779 became effective December 14, 1976.

Amendment 39-2800 became effective January 6, 1977.
