SUPPLEMENTARY INFORMATION:  

REGULATORY TEXT:   83-06-08 SHORT BROTHERS AND HARLAND LTD.: Amendment 39-4595. Applies to Model SC 7, Series 3 airplanes certificated in any category.

COMPLIANCE: Required as indicated, unless already accomplished.

To prevent failure of a main landing gear brake flange and subsequent loss of both main and emergency brake systems, accomplish the following:
a) Within the next 200 landings after the effective date of this AD for airplanes equipped with brake flange Part No. EH183134 and having 5,000 or more landings in service or for airplanes equipped with brake flange Part No. EH183712 and having 1,000 or more landings in service, perform a dye penetrant inspection of the main landing gear brake flanges as instructed in paragraph 2 of Dowty Rotol Service Bulletin No. 32-10M, Rev. 1, dated February 17, 1982.
1) If no cracks are found, return the airplane to service.
2) If cracks are found, prior to further flight, replace the brake flange with a serviceable unit of the same part number.

b) Repeat the inspection of paragraph a) above at 1,000 landing intervals. When the brake flange is replaced, these repeated inspections may be discontinued until the newly installed brake flange has accumulated the total number of landings as prescribed in paragraph a) above.

c) Operators who have not kept records of total landings in service may convert airplane hours time-in-service to total landings in service at the rate of two landings per hour.

d) The intervals between the repetitive inspections required by this AD may be adjusted up to 10 percent of the specified interval to allow accomplishing these inspections concurrent with other scheduled maintenance of the airplane.

e) Aircraft may be flown in accordance with Federal Aviation Regulation 21.197 to a location where this AD can be accomplished.

f) An equivalent method of compliance with this AD if used must be approved by the Manager, Aircraft Certification Staff, AEU-100, Europe, Africa and Middle East Office, FAA, c/o American Embassy, 1000 Brussels, Belgium.

This amendment becomes effective on April 4, 1983.
