REGULATORY TEXT:  
81-03-03 B.F. GOODRICH: Amendment 39-4027. Applies to the following brake assemblies with the following brake lining cups:

Brake Assembly P/Ns

2-1195-7, 2-1195-8, 2-1367, 2-1367-1, 2-1367-2, 2-1147, 2-1147-3 and 2-1190

Brake Lining Cups with part no./date codes as follows:

342-58	342-64	342-94	342-95
E12 80	D18 80	D10 80	E7 80
E19 80	D28 80		
E20 80	E17 80		
G19 80	G13 80		
H9 80	G19 80		

These brake assemblies are used on but not limited to Boeing 727 and Lockheed L-1011 aircraft.

Within 60 days from the effective date of this AD, the above identified lining cups shall not be used on TSO'd brake assemblies unless the following has been accomplished:

a) All spare assemblies (i.e. brakes, pressure plates, lining carriers and torque plates) which have been assembled from inventory containing suspected cups, to be visually inspected at the lining cup button cavity for cracks using 4X or greater magnification. Remove cups with visible cracks and replace with serviceable parts. An alternative to the inspection is replacement of suspected cups with parts which are not in the suspected part no./date code groups.

b) Records must be kept to assure traceability of inspections and rework of all assemblies and brake assemblies which were assembled from inventory containing suspected cups.

c) Brake assemblies installed on aircraft prior to the effective date of this AD do not require removal or inspection.

B.F. Goodrich Service Bulletins No. 390 (for the Lockheed L-1011) and No. 391 (for the Boeing 727) dated October 9, 1980 also apply to the subject matter of this AD.

This amendment becomes effective January 28, 1981.
