Primary finding
Probable cause
The pilot’s failure to maintain an adequate descent rate during the landing approach, which resulted in an impact with terrain short of the runway threshold.
Investigator assessment
Analysis narrative
The pilot reported that while on approach for landing, the visual approach slope indicator showed that he was above the glide slope. He deployed flaps to descend and re-intercept the glide slope. After the pilot noticed that he was a little low he added power to arrest the descent rate. However, the landing gear impacted a berm about 90 feet from the runway approach threshold, which resulted in substantial damage to both wings. The pilot reported that the airplane had no preimpact mechanical malfunctions or failures that would have precluded normal operation.
