FAA Proposes New Airworthiness Directive for Short Brothers Model SD3-60 SHERPA Airplanes

The Federal Aviation Administration (FAA) has proposed a new airworthiness directive requiring replacement of a pneumatic de-icing boot pressure indicator switch on Short Brothers Model SD3-60 SHERPA, SD3-SHERPA, SD3-30, and SD3-60 series airplanes to prevent misleading information and potential loss of controllability due to ice accumulation on the airplane's leading edges.
