AD 2001-13-51 required inspecting certain driveshafts for a crack, a loose bolt or nut, or red powder residue and replacing a driveshaft if there is a crack, a loose bolt or nut, or red powder residue. AD 2001-13-51 also required notifying the FAA within 10 days if a crack is found in the driveshaft. This new AD retains the inspection requirement of AD 2001-13-51, expands the applicability to include the Model 429 helicopter, and removes the reporting requirement. This AD is intended to prevent failure of a driveshaft, loss of drive to the main rotor system, and a subsequent emergency landing.", "2015-08-20", 2015, 8, "https://www.federalregister.gov/documents/2015/08/20/2015-20509/airworthiness-directives-bell-helicopter-textron-canada-bell-helicopters", "https://www.govinfo.gov/content/pkg/FR-2015-08-20/pdf/2015-20509.pdf", "Transportation Department; Federal Aviation Administration", "492,159", "We are superseding Airworthiness Directive (AD) 2001-13-51 for Bell Model 206L-4, 407, and 427 helicopters.
