81-17-06 BRITISH AEROSPACE, AIRCRAFT GROUP (formerly British Aircraft Corporation): Amendment 39-4193. Applies to Model BAC 1-11 200 and 400 series airplanes, certificated in all categories, that incorporate a ground charging system as a part of the airplane oxygen system.

Compliance is required as indicated unless already accomplished.

To minimize the possibility of fire originating in the oxygen system during recharging, accomplish the following:

(a) Within the next 10 hours time in service after the effective date of this AD, unless already accomplished, install a placard in clear view of the pilots and at the oxygen filler valve to read as follows:

"REMOVE OXYGEN BOTTLES FROM AIRPLANE FOR CHARGING"

(b) Within the next 50 hours time in service after the effective date of this AD, unless already accomplished, replace the non-return valve, P/N WKA 30035 or WKA 30035/1, in accordance with British Aerospace, Aircraft Group, Alert Bulletin 35-A-PM 5541, Issue 2, dated August 31, 1978, (hereinafter referred to as the service bulletin) with a new valve, P/N WKA 30035/1, modified to WKA 37395 configuration in accordance with paragraph 2.4 of section 2, "Accomplishment Instructions" of the service bulletin, or an FAA-approved equivalent.

(c) Prior to October 1, 1981, accomplish British Aerospace, Aircraft Group, Modification PM 5291, or an FAA-approved equivalent.

(d) Prior to October 1, 1981, if equipped with self-sealing charging valve, accomplish British Aerospace, Aircraft Group, Modification PM 5413, or an FAA-approved equivalent.

(e) As an alternative to complying with paragraphs (a), (b), (c), or (d) of this AD, deactivate the ground charging system in accordance with paragraph 2.3.2 of Section 2, "Accomplishment Instructions," of the service bulletin, or an FAA-approved equivalent.

(f) For airplanes incorporating oxygen shut-off valves, Normalair P/N OP 6370 or Adams P/N 6D/2313 MK 10 A:

(1) Within the next 300 hours time in service or within the next 60 days after the effective date of this AD, whichever occurs sooner, unless already accomplished within the last 2100 hours time in service or 10 months, whichever is the shorter, and thereafter at intervals not to exceed 2400 hours time in service, or 1 year, whichever occurs sooner, inspect ground charging and passenger and crew supply shut-off valves, in accordance with paragraph 2.2.3 of section 2, "Accomplishment Instructions" of the service bulletin, or an FAA-approved equivalent. Precautions regarding securing and operation of the shut-off valves are outlined in paragraph 2.2.1 of section 2, "Accomplishment Instructions" of the service bulletin.

(2) If, during the inspections required by paragraph (f)(1) of this AD, a valve is determined to be unserviceable in accordance with the criteria established in paragraph 2.2.3 of section 2, "Accomplishment Instructions" of the service bulletin, before further flight, replace the valve with a serviceable part of the same part number, and continue to inspect the valve in accordance with paragraph (f)(1) of this AD, or replace with P/N WKA 30342 valve, in accordance with British Aerospace, Aircraft Group, Modification No. PM 5575, or an FAA-approved equivalent.

(g) Upon satisfactory compliance with paragraphs (b), (c), (d), and (f) of this AD, the placard required by paragraph (a) may be removed.

(h) In accordance with FAR Sections 21.197 and 21.199, the airplane may be flown to a location where the required modification can be made.

(i) For purposes of complying with this AD, an FAA-approved equivalent must be approved by the Chief, Aircraft Certification Staff, AEU-100, Federal Aviation Administration, Europe, Africa, and Middle East Office, c/o American Embassy, Brussels, Belgium.

The manufacturer's specifications and procedures identified and described in this directive are incorporated herein and made a part hereof pursuant to 5 U.S.C. 552(a)(1). All persons affected by this directive who have not already received these documents from the manufacturer may obtain copies upon request to British Aerospace, Inc., Box 17414, Dulles International Airport, Washington, DC 20041. These documents may be examined at FAA Headquarters, Room 916, 800 Independence Avenue, SW., Washington, DC 20591.
