This proposed AD was prompted by reports of five engine in-flight shutdowns and seven unplanned engine removals. This proposed AD would require inspections, cleaning, and engine modifications to address coking in the No. 4 bearing compartment and oil pressure and scavenge tubes. We are proposing this AD to prevent an engine fire, a fractured fan drive shaft, and damage to the airplane.", "2011-11-23", 2011, 11, "https://www.federalregister.gov/documents/2011/11/23/2011-30138/airworthiness-directives-pratt-and-whitney-turbofan-engines", "https://www.govinfo.gov/content/pkg/FR-2011-11-23/pdf/2011-30138.pdf", "Transportation Department; Federal Aviation Administration", "492,159", "We propose to adopt a new airworthiness directive (AD) for all Pratt & Whitney PW4050, PW4052, PW4056, PW4056(-3), PW4156, PW4060, PW4060(- 3), PW4060A, PW4152, PW4152(-3), PW4156A, PW4158, PW4158(-3), PW4460, PW4460(-3), PW4462, and PW4462(-3)...", 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": ["2011-30138"], "units": {}, "query_ms": 11.73364999704063, "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"}
