Abstract
This amendment revises airworthiness directive (AD) 96-08-01, that is applicable to Hamilton Standard Model 14RF-9 propellers. The current AD superseded priority letter AD 95-24-09, and requires an ultrasonic shear wave inspection, adds a one-time visual and fluorescent penetrant inspection, and repair of the propeller blade shank. This revision will add a new shank eddy current inspection and will allow repair of certain blade shanks removed from service under the current AD. The actions specified by this AD are intended to prevent propeller blade separation due to propeller blade shank cracking that can result in loss of control of the aircraft.
