RELATIVELY LOW TIME SMA PLT DOES GAR AFTER VEERING OFF RWY ON LNDG ATTEMPT.

Narrative

AT SUS ARPT WITH 3 PAX ON BOARD; INCLUDING THE PLT. APCHING N RWY (RWY 8L); FACING XWIND THAT VARIED FROM 170-210 DEGS AT 10-15 KTS. ON FINAL APCH I HAD AIRSPD OF 70-80 KTS; WHICH KEPT INCREASING THE CLOSER I GOT TO THE GND. ALSO; I FELT THAT I HAD TO CRAB INCREASINGLY; AS I GOT CLOSER TO THE RWY. LIKEWISE; I HAD TO INCREASE L RUDDER IN ORDER TO KEEP PLANE IN LINE WITH THE RWY. ON TOUCHDOWN; WE BOUNCED ONCE AND ON RECOVERING; BROUGHT THE PLANE TO THE RWY ON ALL 3 GEAR. AIRSPD WAS STILL HIGH AND THE PLANE QUICKLY VEERED TO THE L. IN A FRACTION OF TIME WE WERE OFF THE RWY CONCRETE AND INTO THE GRASS. AIRSPD STILL HOT; I PUT IN FULL THROTTLE AND WE WERE AIRBORNE MOMENTS LATER. ON CLBOUT WE HEARD A SOUND OF IMPACT (THINKING OF RWY LIGHTS) AND GOT BACK INTO THE PATTERN. ON A LOW PASS-OVER; WE GOT THE TWR TO VERIFY THAT OUR LNDG GEAR APPEARED NORMAL; THEN LANDED WITHOUT A HITCH. ON DISEMBARKING; A QUICK INSPECTION OF THE PLANE REVEALED SUBSTANTIAL DAMAGE TO THE LEADING EDGE OF BOTH SIDES OF THE TAIL WING; SOME SCRAPING TO THE UNDER CARRIAGE OF THE FUSELAGE; AND 2 INCHES CUT INTO THE TIP OF THE PROP BLADE. APPARENTLY WE HAD FLOWN INTO THE TOP OF A TEMPORARY FENCE LOCATED 20-30 FT TO THE L OF RWY 8L. ON TAKING OFF FROM THE GRASS; WE HAD IMPACTED THE METAL SUPPORTS FOR THE ORANGE PLASTIC FENCING. THIS EXPLAINS THE RECTANGULAR INDENTATIONS LEFT IN THE TAIL WINGS. HUMAN PERFORMANCE CONSIDERATIONS: 1) DECISION TO GO AROUND SHOULD HAVE BEEN MADE LONG BEFORE TRAVERSING INTO THE GRASS; OR EVEN ATTEMPTING THE LNDG. 2) ONCE ON THE GND; WE SHOULD HAVE STAYED ON THE GND; EVEN IF IT WOULD HAVE MEANT DAMAGING THE ENG; GEAR; ETC. 3) UNRECOGNIZED PLT FATIGUE. A) HAD COMPLETED 7 TKOFS AND LNDGS AT COLUMBIA; MO; WITHIN 3 HRS PRIOR TO INCIDENT. B) HUNGER (LOW BLOOD SUGAR). HAD NOT EATEN SINCE PREVIOUS NIGHT. THIS FACTOR MAY HAVE DULLED JUDGEMENT AND DECISION MAKING SWIFTNESS. C) PLT FELT EXHAUSTED BUT DID NOT THINK IT WAS EXCESSIVE OR OUT OF THE ORDINARY; AS TO BE ALARMED OR CONCERNED.
