Sorry, I shouldn't have paraphrased "attributed to mast bumping" rather should have said that TheDoctorMedic was indicating that mast bumping couldn't be ruled out in New York accident simple because the mast hadn't been fractured (as some were indicating). NTSB reported 114AE had about a 5 degree bend of mast just below the stops (which had left an impression on the mast) and a 20 degree bend below the swashplate. When that occurred isn't clear.
