Aircraft
I departed RDU and was given a heading which I turned to using a Sandel HSI. The HSI was indicating incorrectly causing me to deviate substantially from the assigned heading. My maintenance facility told me that the problem was probably caused by an electrical disruption. Pilots operating with a Sandel HSI should be made aware of this potential problem.
The reporter states that his Mechanic believes that the electrical components of the HSI system were not properly seated in their mount or there was a problem with the mount which is being replaced.
SR22 pilot experiences HSI errors shortly after takeoff causing significant heading deviations from the assigned heading. A poor electrical connection was thought to have caused the anomaly.
