Airworthiness Directives; Honeywell International LTS101-600A Series and LTS101-700D-2 Turboshaft Engines and LTP101-600A-1A, and LTP101-700A-1A Turboprop Engines

Résumé
The FAA proposes to adopt a new airworthiness directive (AD) for Honeywell International LTS101-600A series and LTS101-700D-2 turboshaft engines and LTP101-600A-1A, and LTP101-700A-1A turboprop engines with power turbine blades, part number (P/N) 4-141-084-06, installed. This proposed AD would require removing power turbine blades, P/N 4-141-084-06 from service, using a drawdown schedule specified in this proposed AD. This proposed AD results from reports of fatigue cracks in the airfoil of the power turbine blade. We are proposing this AD to prevent fracture of the power turbine blade airfoil, which could result in sudden loss of engine power.
