## Discrepancy

WHILE CLIMBING THROUGH 10,000 FEET THE OXYGEN MASKS DEPLOYED INADVERTENTLY.  THE FLIGHT LANDED IN PIT WITH NO FURTHER INCIDENTS.  MAINTENANCE TROUBLESHOT THE WIRING, REPLACED THE SOLENOID AND OXYGEN PANEL, AND HAD A TEST FLIGHT.  THE TEST FLIGHT WAS GOOD AND THE AIRCRAFT WAS RELEASED FOR SERVICE.
