## Abstract

This amendment adopts a new airworthiness directive (AD) that is applicable to Rolls-Royce Limited (R-R) Dart series turboprop engines. This action requires initial and repetitive fuel burner fuel flow calibration checks, and overhaul or replacement of fuel burners. This amendment is prompted by reports of an uncontained engine failure and fire due to HPT disk rupture caused by fuel burner failure. The actions specified in this AD are intended to prevent HPT disk rupture, which can result in an uncontained engine failure, engine fire, and damage to the aircraft.
