An airworthiness directive has been issued for all Honeywell TFE731-20R, -20AR, -20BR, -40, -40AR, -40R, -50R and -60 turbofan engines. It was prompted by a report of a quality escape of about 8,000 second-stage low-pressure turbine (LPT2) rotor blades manufactured by Honeywell’s Chihuahua, Mexico, manufacturing operation since 2009. This AD requires removing and inspecting certain LPT2 rotor blades. Cost of the fix is $3,480.
