This proposed AD would require inspecting each MRB for a crack or damage. This proposed AD is prompted by a report that a crack was found on an MRB during a tear-down inspection. The proposed actions are intended to detect a crack in the MRB, which could lead to failure of the MRB and subsequent loss of control of the helicopter. 2014-10-03 2014 10 https://www.federalregister.gov/documents/2014/10/03/2014-23588/airworthiness-directives-kaman-aerospace-corporation-kaman-helicopters https://www.govinfo.gov/content/pkg/FR-2014-10-03/pdf/2014-23588.pdf Transportation Department; Federal Aviation Administration 492,159 We propose to adopt a new airworthiness directive (AD) for Kaman Model K-1200 helicopters with certain main rotor blades (MRB) installed.
