The FAA proposes to adopt a new airworthiness directive (AD) for Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model BO- 105A, BO-105C, BO-105S, MBB-BK 117 A-1, MBB-BK 117 A-3, MBB-BK 117 A-4, MBB-BK 117 B-1, MBB-BK 117 B-2, and MBB-BK 117 C-1 helicopters. This proposed AD would require inspecting the starter-generator electrical ground connection, retrofitting the starter-generator wire harness, and depending on model, revising the Rotorcraft Flight Manual (RFM) for your helicopter. This proposed AD was prompted by a report of a loss of electrical ground between the starter-generator and the generator voltage regulator (regulator). The proposed actions are intended to correct an unsafe condition on these products.
