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. ## Affected data sheets (2) (OpenAirDocs) The type certificate data sheets whose models the AD names. - [TCDS A3WE](https://openairdocs.org/tcds/A3WE): The Boeing Company; names 6 of 6 models: 727-100 Series, 727 Series, 727-200 Series, 727-100C Series, 727-200F Series, 727C Series - [TCDS A23WE](https://openairdocs.org/tcds/A23WE): Lockheed Martin Corporation; names 4 of 4 models: L-1011-385-1-14, L-1011-385-3, L-1011-385-1, L-1011-385-1-15 ## Registered aircraft it may apply to (OpenAirDocs) Matched by airframe and engine model; the AD's applicability may narrow it by serial number, part number or equipment. - Aircraft: 29 (29 by airframe model, 0 by engine model) - Makers: Boeing 25, Lockheed 4 Models with the most aircraft: - [Boeing 727-223](https://openairdocs.org/model/boeing-727-223): 9 aircraft (airframe model) - [Boeing 727-227](https://openairdocs.org/model/boeing-727-227): 4 aircraft (airframe model) - [Boeing 727-225](https://openairdocs.org/model/boeing-727-225): 2 aircraft (airframe model) - [Lockheed L-1011-385-1](https://openairdocs.org/model/lockheed-l-1011-385-1): 2 aircraft (airframe model) - [Boeing 727-200F](https://openairdocs.org/model/boeing-727-200f): 1 aircraft (airframe model) - [Boeing 727-200](https://openairdocs.org/model/boeing-727-200): 1 aircraft (airframe model) - [Boeing 727-212](https://openairdocs.org/model/boeing-727-212): 1 aircraft (airframe model) - [Boeing 727-230](https://openairdocs.org/model/boeing-727-230): 1 aircraft (airframe model) - [Boeing 727-232](https://openairdocs.org/model/boeing-727-232): 1 aircraft (airframe model) - [Boeing 727-243](https://openairdocs.org/model/boeing-727-243): 1 aircraft (airframe model) - [Boeing 727-247](https://openairdocs.org/model/boeing-727-247): 1 aircraft (airframe model) - [Boeing 727-264](https://openairdocs.org/model/boeing-727-264): 1 aircraft (airframe model) - [Boeing 727-281](https://openairdocs.org/model/boeing-727-281): 1 aircraft (airframe model) - [Boeing 727-277](https://openairdocs.org/model/boeing-727-277): 1 aircraft (airframe model) - [Lockheed L-1011-385-1-15](https://openairdocs.org/model/lockheed-l-1011-385-1-15): 1 aircraft (airframe model) - [Lockheed L-1011-385-3](https://openairdocs.org/model/lockheed-l-1011-385-3): 1 aircraft (airframe model) All 16 models: https://openairdocs.org/ad/81-03-03/models.md Every aircraft: https://openairdocs.org/ad/81-03-03/aircraft.md Its text cites no advisory circulars or STCs. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/).
