AD: McCauley

AD NUMBER: 2010-14-20

MANUFACTURER: McCauley Propeller Systems Model 4HFR34C653/L106FA Propellers
SUBJECT: Airworthiness Directive 2010-14-20

SUMMARY: This AD requires a onetime fluorescent penetrant inspection (FPI) and eddy current inspection (ECI) of the propeller hub for cracks. This AD results from reports of 10 hubs found cracked during propeller overhaul. The FAA is issuing this AD to prevent failure of the propeller hub, which could cause blade separation, damage to the airplane, and loss of control of the airplane.
