## Probable cause

THE CAPTAIN MISJUDGED DISTANCE AND ALTITUDE TO THE RUNWAY AND ALLOWED THE AIRCRAFT TO TOUCH DOWN JUST SHORT OF THE RUNWAY LIP.  THE RUNWAY LIP WAS A RELATED FACTOR.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Undershoot, approach - vfr pattern - final approach
  - distance - misjudged, pilot in command (cause)
  - altitude - misjudged, pilot in command (cause)
- In flight collision with terrain/water, landing - flare/touchdown
  - proper touchdown point - not attained, pilot in command (cause)
  - terrain condition - runway (contributing factor)
  - landing gear,tire - ruptured
- Loss of control - on ground/water, landing - roll
  - directional control - not possible, pilot in command
  - ground loop/swerve
- On ground/water collision with object, landing

## Analysis

THE FLT WAS CLEARED FOR A VISUAL APCH TO RWY 21, WHICH HAD AN OPNL VASI.  THE CAPT RPRTD THAT AT ABOUT 200' AGL ON THE APCH, THE ACFT WAS 'BELOW THE VASI' & HE INCREASED POWER TO CORRECT THE SITUATION.  HOWEVER, THE ACFT TOUCHED DOWN JUST SHORT OF THE RWY & THE MAIN GEAR HIT THE RWY LIP, WHICH WAS ABOUT 6' ABOVE THE OVERRUN AREA.  THE MAIN GEAR WHEELS HIT THE LIP & THE RIGHT MAIN TIRES BLEW OUT.  THE ACFT CONTD DOWN THE RWY, UNTIL IT SLOWED TO ABOUT 60 KTS, THEN IT VEERED OF THE RIGHT SIDE OF THE RWY, HIT 2 TWY MARKERS & CAME TO REST WITH SUBSTANTIAL DMG.
