Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that while on short final, two flocks of geese departed the field in front of his airplane; "no immediate evasion action was necessary". During the landing roll, the airplane began to swerve and veered off the runway to the left. The pilot reported that he "over-applied brake" and subsequently nosed over after attempting to avoid the runway edge lights. The pilot reported there were no pre-impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation. The airplane sustained substantial damage to the empennage.
