## Summary

We propose to adopt a new airworthiness directive (AD) for all Safran Helicopter Engines, S.A., Arriel 2E turboshaft engines. This proposed AD was prompted by reports of ruptured front support pins on the accessory gearbox front support. This proposed AD would require replacement of the accessory gearbox front support. We are proposing this AD to address the unsafe condition on these products.
