REGULATORY TEXT:   80-22-03 BRITISH AEROSPACE, AIRCRAFT GROUP (formerly British Aircraft Corporation): Amendment 39-3945. Applies to Model BAC 1-11 series airplanes, certificated in all categories.

Compliance is required as indicated.

To prevent incompatibility between the bayonet connection of Fixed Sockets and Flow Selectors and the hose connection of oxygen masks which could preclude access to oxygen in the passenger cabin or the flight deck, accomplish the following:

(a) Within the next 50 hours time in service after the effective date of this AD, unless already accomplished, check each Fixed Socket and Flow Selector, Normalair P/N's OP4730, 1205X000, 1930W000, or 1931W000 in accordance with either subparagraph (a) or (b) of paragraph 2.1.1 of British Aerospace, Aircraft Group, Alert Service Bulletin 35-A-PM5723, Issue No. 1, dated September 20, 1979, or an FAA-approved equivalent.

(b) If it is found during the check required by paragraph (a) of this AD that a plug gauge or hose connector cannot be inserted fully into one or more Fixed Socket and Flow Selector -

(1) Rework any defective Fixed Socket and Flow Selectors in accordance with paragraph 2B of Normalair Garrett Alert Service Bulletin 35-A23, Revision 1, dated November 26, 1979, or an FAA-approved equivalent; or

(2) Label each such Selector "INOPERATIVE" in accordance with paragraph 2.1.2 of British Aerospace, Aircraft Group, Alert Service Bulletin 35-A-PM5723, Issue No. 1, dated September 20, 1979, or an FAA-approved equivalent.

(3) Pending the accomplishment of paragraph (b)(1) or (b)(2) of this AD, either -

(i) Install a portable oxygen breathing set at each "INOPERATIVE" Selector; or

(ii) Restrict the operating altitude for the airplane to 8,000 feet or less; or

(iii) Limit the number of passengers to no more than the number of operative selectors.

(c) If any Normalair P/N OP4730, 1205X000, 1930W000, or 1931W000 Fixed Socket and Flow Selector is installed in an airplane after accomplishment of the check required by paragraph (a) of this AD, comply with paragraph 2.1.1 of British Aerospace, Aircraft Group, Alert Service Bulletin 35-A-PM5723, Issue No. 1, dated September 20, 1979, or an FAA- approved equivalent, on the newly installed Selector at the time of installation.

(d) If an oxygen mask is installed in an airplane after accomplishment of the check required by paragraph (a) of this AD and the method used was that specified in paragraph 2.1.1(b) of British Aerospace, Aircraft Group, Alert Service Bulletin 35-A-PM5723, Issue No. 1, dated September 20, 1979, or an FAA-approved equivalent, comply with paragraph 2.1.1(b) with newly installed mask.

(e) Within the next 1,200 hours time in service after the effective date of this AD, unless already accomplished, comply with paragraph 2.1.1(a) of British Aerospace, Aircraft Group, Alert Service Bulletin 35-A-PM5723, Issue No. 1, dated September 20, 1979, or an FAA- approved equivalent, and rework any defective Fixed Socket and Flow Selector in accordance with paragraph 2B of Normalair Garrett Alert Service Bulletin 35-A23, Revision 1, dated November 26, 1979, or an FAA-approved equivalent. After rework has been completed, remove the "INOPERATIVE" marking from reworked selectors.

(f) If any Normalair P/N OP4730, 1205X000, 193W000, or 1931W000 Fixed Socket and Flow Selector is installed in an airplane after accomplishment of paragraph (e) of this AD, comply with paragraph 2.1.1(a) of British Aerospace, Aircraft Group, Alert Service Bulletin 35-A-PM5723, Issue No. 1, dated September 20, 1979, or an FAA-approved equivalent, and rework, if necessary, any defective Fixed Socket and Flow Selector in accordance with paragraph 2B of Normalair Garrett Alert Service Bulletin 35-A23, Revision 1, dated November 26, 1979, or an FAA-approved equivalent, at the time of installation.

(g) If an equivalent means of compliance is used in complying with paragraph (a), (b), (c), (d), (e) or (f) of this AD, that equivalent must be approved by the Chief, Aircraft Certification Staff, AEU-100, Europe, Africa, and Middle East Office, FAA, c/o American Embassy, Brussels, Belgium.

This amendment becomes effective October 28, 1980.
