Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain H[eacute]licopt[egrave]res Guimbal (HG) Model Cabri G2 helicopters. This proposed AD was prompted by a report of a potential malfunction of the helicopter emergency locator transmitter (ELT) and subsequent findings of weak ELT signals on 121.5 MHz and 406 MHz frequencies due to improper antenna installation (location). This proposed AD would require revising the existing rotorcraft flight manual (RFM) for the helicopter. The FAA is proposing this AD to address the unsafe condition on these products.
