## Discrepancy

10 MINUTES INTO A TOUR FLIGHT, HYD LIGHT ILLUMINATED.  PILOT RETURNED TO BASE, WHERE THE HYD LIGHT WENT OUT PRIOR TO LANDING.  RT HYD PRESSURE SWITCH WAS CHANGED.  THE RT PRESSURE SWITCH WAS CHOSEN DUE TO THE FACT THAT THE RT HYD MANIFOLD INCLUDING THE PRESSURE SWITCH WERE CHANGED 15.4 HRS EARLIER.
