## Discrepancy

APPROX 3 NM NW OF AIRPORT HEARD A NOISE. A FEW MOMENTS PASSED AND THEN THERE WAS A "POP", A QUICK PRESSURE CHANGE AND AIRFLOW INTO THE COCKPIT. DISCOVERED THE GAPING HOLE WHERE THE CHIN BUBBLE SHOULD BE INSTALLED.  IMMEDIATELY TURNED TOWARD THE AIRPORT AND NOTIFIED CENCOM OF A PRECAUTIONARY LANDING. MEANWHILE WE REDUCED SPEED AND BEGAN A SHALLOW APPROACH INTO THE AIRPORT.
