Summary
The FAA proposes to adopt a new airworthiness directive (AD) for Goodrich De-icing and Specialty Systems "FASTprop'' propeller de- icers, part numbers P4E1188 series, P4E1601 series, P4E2200 series, P4E2271-10, P4E2575-7, P4E2575-10, P4E2598-10, P5855BSW, P6199SW, P6592SW, P6662SW, and P6975-11, installed. This proposed AD would require inspection, repair, or replacement of those "FASTprop'' propeller de-icers that fail visual checks before the first flight each day. This proposed AD results from reports of Goodrich "FASTprop'' propeller de-icers becoming loose or debonded, and detaching from propeller blades during operation. We are proposing this AD to prevent Goodrich "FASTprop'' propeller de-icers from detaching from the propeller blade, resulting in damage to the airplane and possible injury to the passengers and crewmembers.
