0015727 U.S. Department Advisory of Transportation Circular Federal Aviation Administration Subject: GUIDE FOR DEVELOPING AND Date: 5/22/97 AC No: 140-8 EVALUATING AN SFAR 36 Change:

ENGINEERING PROCEDURES MANUAL Initiated by: AIR-110

1. PURPOSE. This advisory circular (AC) sets forth an acceptable means, but not the only means, for developing and evaluating a 14 Code of Federal Regulations (14 CFR) Special Federal Aviation Regulation (SFAR) 36 engineering procedures manual. As such, the terms "shall" and "must" used in this advisory circular pertain to an applicant who chooses to follow the method presented.

2. RELATED CODE OF FEDERAL REGULATIONS (14 CER). 14 CFR parts 1, 21, 43„ 121, 125, 127, 135, 145, SFAR 36, and FAA Order 8000.42, Authorization To Develop & Use Major Repair Data Not Specifically Approved By The Administrator.

3. BACKGROUND. The development of an SFAR 36 engineering procedures manual that adequately covers all pertinent regulations and engineering procedures has proven to be a timeconsuming task for the applicant and the Federal Aviation Administration.

4. DISCUSSION. This AC may be used as a guide for development and evaluation of an engineering procedures manual for major repairs required by SFAR 36, paragraph 4. A sample engineering manual in shown in appendix 1. These "Examples" are intended to illustrate the requirements specified by the SFAR. The SFAR 36 engineering procedures manual should be developed within the limitations of the certificate holder's rating(s) and engineering staff capabilities to develop the technical data for major repairs. The engineering procedures manual must accurately describe the engineering operations use to develop major repairs under SFAR

36. The sample manual includes additional information necessary to administer the regulation such as, the requirement for a list of effective pages, company SFAR 36 organizational chart, and recommending the frequency of reporting requirements.
