What the agency says
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Deutschland GmbH (AHD) Model MBB-BK 117 D-2 helicopters. This proposed AD was prompted by certification test results of a certain common cargo hook beam (CCHB) on the affected helicopters, which revealed that the installed CCHB could result in fuel leakage following a survivable accident. This proposed AD would require modification of the CCHB and fuel system and installation of structural reinforcement. This proposed AD would also prohibit installing a certain CCHB on any helicopter. The FAA is proposing this AD to address the unsafe condition on these products.
