- Loss of control - on ground/water, landing - flare/touchdown
  - in-flight planning/decision - poor, pilot in command (contributing factor)
  - weather condition - tailwind (contributing factor)
  - wrong runway - selected, pilot in command (contributing factor)
  - proper touchdown point - not used, pilot in command (contributing factor)

## Analysis

THE PILOT INITIATED A LANDING ON A 2650 FT LONG RUNWAY IN A 11-18 KNOT QUARTERING TAILWIND CONDITION. HE FLEW THE FINAL APPROACH TOO FAST AND FLARED PREMATURELY. THE ACFT FLOATED DOWN THE RWY, LANDED HARD AND BOUNCED TWICE. THE PLT LOST CONTROL AND THE ACFT DEPARTED THE SIDE OF THE RWY. THE LEFT WING WAS SUBSTANTIALLY DAMAGED ON IMPACT WITH A POLE ON THE SIDE OF THE RWY.
