The documents in Title 14 of the Code of Federal Regulations (14 CFR), formerly called the Federal Aviation Regulations, are the actual legal documents that govern civil aviation operations. Throughout this book the term “14 CFR” is directly interchangeable with the former “FAR.”
It is the responsibility of an IA to have current copies of all the applicable parts of 14 CFR that pertain to aviation maintenance. IAs should refer to rgl.faa.gov to determine the currency of any document they are using.
This chapter contains typical questions taken from applicable Federal Regulations.
Note: On October 16, 2009, the FAA released major amendments to a number of regulations —14 CFR Parts 1, 21, 43 and 45 were affected by these revisions. Although the effective date for these in the Federal Register (FR) was April 14, 2010, only a portion of the changes became effective on that date. The remaining amendments have compliance dates of 18 months after the FR publication date. Currently it is not known when the FAA will update the IA test database and computer testing supplement accordingly with this amendment; therefore the proactive IA applicant will be prepared to answer questions that deal with the regulations as they currently exist as well as those affected by the new amendments. For further information, see the “Reader Resources” page on the ASA website (details are contained in a downloadable PDF of this October 2009 FR).
