Aircraft: FERNANDES DALE R GLASAIR II S-FT 
Aircraft Damage: Substantial
Defining Event: Collision with terr/obj (non-CFIT)
Injuries: 1 None
Flight Conducted Under: Part 91: General aviation - Personal

Analysis

The pilot reported that, while on final approach, he reduced airspeed which resulted in a higher angle of attack and blocking his visibility of the approach threshold. The glide path steepened, and the airplane touched down short of the airstrip. The right main landing gear collided with a rock and sheared off. Shortly thereafter, the left main landing gear sheared off and the airplane slid down the runway substantially damaging the fuselage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot’s failure to establish a controlled descent rate during landing which resulted in the airplane touching down short of the runway.

Findings

Personnel issues Use of equip/system - Pilot
Personnel issues Aircraft control - Pilot
Aircraft Descent rate - Not attained/maintained
