Abstract
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model SA330J helicopters. This AD was prompted by report of failure of a second stage planet gear of the main gear box (MGB). This AD requires replacement of the MGB particle detector assembly with an improved, elongated MGB particle detector assembly, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
