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 student pilot landed on runway 30, which is 4,500-foot-long by 100-foot wide. During rollout, the airplane began veering toward the right side of the runway. The student reported that he "stepped on the right rudder/brakes" and "lost directional control." An estimated 30-foot-long skid mark was observed on the runway leading off its right side. Thereafter, the airplane entered a grassy open field and came to rest upon colliding with the up sloping side of a ravine.

Factual narrative

The student pilot landed on runway 30, which is 4,500 feet long by 100 feet wide. During rollout, the airplane began veering toward the right side of the runway. The student reported that he "stepped on the right rudder/brakes" and "lost directional control." An estimated 30-foot-long skid mark was observed on the runway leading off its right side. Thereafter, the airplane entered a grassy open field and came to rest upon colliding with the upsloping side of a ravine. The emergency locator transmitter (ELT) activated. The student reported that he had a total of 72 hours of flight time, of which 3.2 hours were in solo flight. Airplane recovery personnel reported to the National Transportation Safety Board investigator that the right wing's outboard rib was demolished, about 1 1/2 feet of adjacent leading edge skin was crushed inward, and the firewall was buckled.
