## Narrative

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

(-23) ON A PART 91 FLIGHT FROM SLATON (F49) TO ABERNATHY, TEXAS (F83), N11EN, A MAULE M4-220C LANDED HARD CAUSING A COMPROMISE OF THE STRUCTURAL TUBING.  THE "H" TUBING LOCATED BELOW THE COPILOT SEAT BENT WHEN THE TUBING ON THE FORWARD RIGHT POST BEAM SEPARATED DUE TO CORROSION.  THE STRUCTURAL STRESS FROM THE SEPARATION OF THE POST BEAM WAS TRANSFERRED TO THE "H" STRUCTURE, WHICH ALSO FAILED.  EXAMINATION OF THE SEPARATED TUBING REVEALED THE TUBE WAS COMPLETELY FILLED WITH CORROSION.  THE CAUSE OF THE FAILURE WAS UNDETECTED CORROSION OF THE STRUCTURAL TUBING WELD POINT.  TWO PERSONS WERE ON BOARD.  NO INJURIES WERE SUSTAINED.

## The NTSB's investigation of this event (1)
