AD 2015-14-05 becomes effective August 25, 2015 and effects all JT8D-217Cs and JT8D-219 turbofan engines. This AD was prompted by reports of cracking in the low-pressure turbine (LPT) shaft. This AD requires removing affected LPT shafts from service using a drawdown plan. We are issuing this AD to prevent failure of the LPT shaft, which could lead to an uncontained engine failure and damage to the airplane.
We have updated aircraft status airports within CAMMS in regards to this AD.
