REGULATORY TEXT:  
67-22-04 BRITISH AIRCRAFT: Amdt 39-450 as amended by Amdt. Number 39-912. Applies to Model BAC 1-11 200 and 400 Series Airplanes.

Compliance required as indicated.

To detect failures of joints in the secondary flap transmission shafts, accomplish the following:

(a) On BAC 1-11 200 Series airplanes only, within the next 150 hours' time in service after the effective date of this AD, unless already accomplished, inspect all flap secondary transmission support bearing assemblies in accordance with British Aircraft Corporation (BAC) 1-11 Alert Service Bulletin No. 27-A-PM 1928, Issue 3, or later ARB-approved issue, or FAA- approved equivalent. All defective bearing assemblies must be replaced before further flight in accordance with this Service Bulletin, or FAA-approved equivalent. Non-defective bearing assemblies may be continued in service without further inspection.

(b) On BAC 1-11 200 and 400 Series airplanes, within the next 150 hours' time in service after the effective date of this AD, unless already accomplished within the last 450 hours' time in service and thereafter at intervals not to exceed 600 hours' time in service from the last inspection, conduct a functional check of the flap secondary transmission system followed by a visual examination of the transmission shaft joints as detailed in British Aircraft Corporation Alert Service Bulletin No. 27-A-PM 1928, Issue 3, or later ARB-approved issue, of FAA- approved equivalent. Correct defects found before further flight.

(c) The repetitive functional check and inspections required in paragraph (b) may be discontinued if the airplanes are modified in accordance with BAC Service Bulletin 27-PM-1928 paragraphs (a) and (b) and BAC Service Bulletin PM-2720 (a) and (b), or modified in accordance with BAC Service Bulletin PM-2720 (a), (b), (c), and (d), or FAA-approved equivalent.

(d) Upon request of the operator, and FAA maintenance inspector, subject to prior approval of the Chief, Aircraft Certification Staff, FAA Europe, Africa, and Middle East Region may adjust the repetitive inspection intervals specified in this AD to permit compliance at an established inspection period of the operator if the request contains substantiating data to justify the increase for that operator.

Amendment 39-450 effective August 19, 1967.

This amendment (39-912) becomes effective January 11, 1970.
