Mack Mesa Airport
Aircraft Accident/Incident Report

Mack, Colorado 81525
Saturday, August 28, 1999 11:30 MDT

NTSB Narrative Summary Released at Completion of Accident

The pilot had landed at this airport 'at least a dozen times' in the past 15 years, and was aware of 'a low crop at the approach end of [runway] 25.' He said he had this same picture in his mind as he made his approach. When he was approximately 200 to 300 feet from the runway, he realized he was too low (the corn stalks were 8 to 10 feet tall). He applied power and up elevator, but the airplane contacted the corn stalks, settled to the ground, rolled a short distance, then nosed over.

NTSB Probable Cause Narrative

The pilot misjudging his distance and altitude from the runway. A factor was the tall crops.
