## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-23) INSPECTOR'S STATEMENT:^PRIVACY DATA OMITTED^.  I INTERVIEWED THE CAPT. ^PRIVACY DATA OMITTED^ HE STATED THAT WHEN HE DISCONNECTED THE YAW DAMPER ON SHORT FINAL IN GROUND EFFECT, HE EXPERIENCED A SEVERE YAW TO THE RIGHT WHICH RESULTED IN THE RIGHT WING TIP CONTACTING THE RUNWAY.  HE APPLIED FULL LEFT AILERON AND RUDDER TO CORRECT THE YAW RESULTING IN THE LEFT WING TIP CONTACTING THE RUNWAY.  HE SAW THAT THE YAW CYCLES WERE BECOMING LARGER SO HE ELECTED TO APPLY FULL POWER AND GO AROUND.  PUBLISHED PROCEDURES FOR THE LEAR 25 CALL FOR THE YAW DAMPER TO BE DISCONNECTED ON SHORT FINAL.  DISCONNECTING THE YAW DAMPER AT THAT LATE STAGE IN THE LANDING PROCEDURE DOES NOT ASSURE A STABILIZED FLIGHT PATH.  I BELIEVE THAT THE PROCEDURE SHOULD BE MODIFIED TO CALL FOR DISENGAGEMENT OF THE YAW DAMPER AT THE OUTER MARKER OF FINAL APPROACH FIX CONSISTENT WITH STABILIZED APPROACH CONCEPTS.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
