This proposed AD was prompted by low-pressure compressor (LPC) case A-frame hollow locating pins that may have reduced integrity due to incorrect heat treatment. This proposed AD would require replacement of the LPC case A-frame hollow locating pins. We are proposing this AD to correct the unsafe condition on these products.", "2017-09-28", 2017, 9, "https://www.federalregister.gov/documents/2017/09/28/2017-20718/airworthiness-directives-rolls-royce-plc-turbofan-engines", "https://www.govinfo.gov/content/pkg/FR-2017-09-28/pdf/2017-20718.pdf", "Transportation Department; Federal Aviation Administration", "492,159", "We propose to adopt a new airworthiness directive (AD) for certain Rolls-Royce plc (RR) RB211-Trent 875-17, RB211-Trent 877-17, RB211-Trent 884-17, RB211-Trent 884B-17, RB211-Trent 892-17, RB211- Trent 892B-17, and RB211-Trent 895-17 turbofan engines....", null]], "columns": ["document_number", "title", "type", "abstract", "publication_date", "pub_year", "pub_month", "html_url", "pdf_url", "agency_names", "agency_ids", "excerpts", "regulation_id_numbers"], "primary_keys": ["document_number"], "primary_key_values": ["2017-20718"], "units": {}, "query_ms": 0.4494478926062584, "source": "Federal Register API & Regulations.gov API", "source_url": "https://www.federalregister.gov/developers/api/v1", "license": "Public Domain (U.S. Government data)", "license_url": "https://www.regulations.gov/faq"}
