Abstract
The FAA is adopting a new airworthiness directive (AD) for all Hamilton Sundstrand Corporation (Hamilton Sundstrand) Model 14SF-17 and 14SF-19 propellers. This AD was prompted by a report of an auxiliary motor and pump failing to feather a propeller in flight. This AD requires replacement of a certain auxiliary motor and pump. This AD also prohibits installation of a certain auxiliary motor and pump on any propeller. The FAA is issuing this AD to address the unsafe condition on these products.
