{"abstract":"The Federal Aviation Administration (FAA) amends the maintenance regulations for domestic, flag, and supplemental operations, and for commuter and on-demand operations for aircraft type certificated with a passenger seating configuration of 10 seats or more (excluding any pilot seat). The new rules require affected air carriers and operators to develop policies, procedures, methods, and instructions for performing contract maintenance that are acceptable to the FAA, and to include them in their maintenance manuals. The rules also require the air carriers and operators to provide a list to the FAA of all persons with whom they contract their maintenance. These changes are needed because contract maintenance has increased to over 70 percent of all air carrier maintenance, and numerous investigations have shown deficiencies in maintenance performed by contract maintenance providers. These rules will help ensure consistency between contract and in-house air carrier maintenance and enhance the oversight capabilities of both the air carriers and the FAA.","action":"Final rule.","agencies":[{"raw_name":"DEPARTMENT OF TRANSPORTATION","name":"Transportation Department","id":492,"url":"https://www.federalregister.gov/agencies/transportation-department","json_url":"https://www.federalregister.gov/api/v1/agencies/492","parent_id":null,"slug":"transportation-department"},{"raw_name":"Federal Aviation Administration","name":"Federal Aviation Administration","id":159,"url":"https://www.federalregister.gov/agencies/federal-aviation-administration","json_url":"https://www.federalregister.gov/api/v1/agencies/159","parent_id":492,"slug":"federal-aviation-administration"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2015/03/04/2015-04179.html","cfr_references":[{"chapter":null,"citation_url":null,"part":121,"title":14},{"chapter":null,"citation_url":null,"part":135,"title":14}],"citation":"80 FR 11537","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"Effective May 4, 2015 except for Sec.
