## Discrepancy

SWITCH ACTUATOR IS CUTTING A GROOVE IN THROTTLE RAMPS.  AS IT WEARS, IT CHANGES WHEN THE GEAR HORN SOUNDS TO A POINT WHERE IT WILL NOT SOUND AT ALL.  WE MAINTAIN 5 NEW AIRCRAFT OF THIS TYPE.  ALL HAVE HAD GEAR WARNING PROBLEMS.  SUBMITTER RECOMMENDS CHANGING THROTTLE RAMP MATERIAL TO SOMETHING HARDER THAN ALUMINUM.
