NTSB Identification: CEN11CA411
14 CFR Part 91: General Aviation

NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The pilot entered the traffic pattern for a visual approach to the runway. He reported that the final approach descent was faster than he anticipated due to the high humidity and high density altitude. He added more engine power to arrest the descent rate, but the airplane landed short of the runway in a wet, grass field and came to rest upright. A postaccident examination of the airplane revealed that the main landing gear separated and the aft carry-through wing spar was bent. The pilot reported there were no mechanical anomalies with the airplane that would have precluded normal operation.


The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
  • The pilot's failure to maintain a proper glide path during the visual approach.
