## Discrepancy

DURING FLIGHT, THE OVERHEAD FAN STOPPED WORKING AND WOULD COME ON INTERMITTENTLY.  DURING TROUBLESHOOTING, ON GROUND POWER, TAPPING THE MOTOR STARTS THE FAN TURNING TEMPORARILY.  SUSPECTED INTERNAL WIRING FAULT.  RECOMMENDATIONS:  DEVELOP AND APPROVE AN AFTERMARKET BLOWER BY A DIFFERENT MFG.
