Abstract
The FAA is adopting a new airworthiness directive (AD) for all Hamilton Sundstrand Corporation (Hamilton Sundstrand) Model 14SF-7, 14SF-15, and 14SF-23 propellers. This AD was prompted by a report of an auxiliary motor and pump failing to feather a propeller in flight. This AD requires replacing a certain auxiliary motor and pump. This AD also prohibits installation of a certain auxiliary motor and pump. The FAA is issuing this AD to address the unsafe condition on these products.
