## Background

The Office of Aviation Safety in the Federal Aviation Administration chartered a team to assess the adequacy of current and pending regulations, policy, guidance and past practices for non-Type Certificate (TC) holders to obtain approval for developing replacement parts, alterations, and repairs. This Repair Alteration Fabrication (RAF) team reviewed all current regulations, policy and practices pertaining to the approval of replacement parts, repairs and alterations of critical engine parts. The team further reviewed concerns raised by TC holders and others, including the evaluation of other approval methods used by repair stations and owner/operator maintenance facilities. The team met with industry groups and companies to obtain additional information to assist them. The results of their efforts are a number of conclusions and recommendations they believe will improve the FAA's approval processes and foster the consistent application of safety standards for replacement parts, repairs, and alterations. This study is entitled “Aviation Safety (AVS) Repair, Alterations and Fabrication (RAF) Study.”
