## Discrepancy

LANDED UNDER AMBER ALERT DUE TO A GEAR EXTENSION AND STEERING PROBLEM.  AFTER SELECTION OF LANDING GEAR DOWN ON FINAL APPROACH, THE DOORS OPENED YET THE GEAR DID NOT EXTEND.  FOLLOWED THE GRAVITY GEAR EXTEND PROCEDURES, AND THE GEAR EXTENDED AND LOCKED WITHOUT FURTHER INCIDENT.  RESET THE GEAR MANUAL EXTENSION HANDLE, AND REPLACED THE LANDING GEAR SELECTOR (SEQUENCING) VALVE.  ACCOMPLISHED THE NORMAL EXTENSION/RETRACTION TEST.
