Unsafe condition
Within 100 hours time-in-service: (1) For all helicopters: (i) Inspect the oil line restrictor for blockage. If there is any blockage in the restrictor, before further flight, inspect the freewheel assembly clutch, inner shaft, outer shaft, forward seal, cap, and bearings for wear, corrosion, nicks, scratches, and cracks; the splines for wear, cracks, chipped teeth, and broken teeth; the housing for flaking; and for free rotation and engagement of the clutch and bearing. If there is any damage that exceeds allowable limits or if the clutch or bearing does not engage or freely rotate, before further flight, repair or replace the freewheel assembly. (ii) Clean, inspect, and flush each removed fitting, restrictor, tube, hose, and filter with dry cleaning solvent. Do not approve for return to service until each restrictor is free from contamination. (2) For Model 206A, 206B, 206L, 206L-1, 206L-3, and 206L-4 helicopters with a reducer, replace the reducer with a filter part number 50-075-1.
Affected ADs
This AD defines the unsafe condition as a blocked oil line restrictor. This condition could cause failure of the freewheel assembly, which could result in failure of the main rotor mast and subsequent loss of control of the helicopter.
