NTSB Issues Recommendation to Transport Canada Regarding Raytheon/Hawker Beechjet 400A Engines

The National Transportation Safety Board (NTSB) has issued a new safety recommendation, designated as A-17-007 and referenced under NTSB number ENG14IA013. This directive is addressed specifically to Transport Canada. The core of the recommendation requires that all JT15D-5 engines installed on Raytheon/Hawker Beechjet 400A airplanes be modified. The purpose of this modification is to dampen rub-induced excitation. This specific mechanical issue can occur between the engine fan and the fan case. These events are triggered during birdstrike or foreign object ingestion scenarios. The NSB emphasizes that these modifications are necessary to mitigate the risks associated with such external impacts on the engine components.
