Probable cause

The pilot’s failure to maintain directional control during landing, which resulted in a runway excursion and the airplane’s subsequent noseover.

Findings · 2

NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.

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 he performed a normal three-point landing in the tailwheel-equipped airplane, and, during the landing roll, the airplane veered to the right. The pilot corrected by applying left rudder, and, shortly after, the airplane "pulled hard to the right." Despite the pilot's control inputs, the airplane exited the right side of the runway onto soft gravel and nosed over, which resulted in structural damage to the fuselage. The pilot added that he believed the right brake was “dragging significantly.” Postaccident examination of the airplane revealed that the right brake caliper brake line attachment fitting was bent outward, toward the wheel assembly, which allowed for a portion of the brake line attached to the fitting to contact the inner wheel assembly. Associated rub marks on the inboard wheel assembly were found, consistent with contact with the brake line sleeve while the wheel was not in motion, and likely resulted from the accident. No additional anomalies were noted with the right brake or wheel assembly. The accident is consistent with the pilot not maintaining directional control during landing.

Factual narrative

On March 4, 2020, about 2315 mountain standard time, a Cessna 182A, N4031D, was substantially damaged when it was involved in an accident near Moab, Utah. The pilot was not injured. The airplane was operated as a Title 14 Code of Federal Regulations part 91 personal flight. The pilot reported that he performed a normal three-point landing in the tailwheel-equipped airplane on runway 21 at night. During the landing roll, the airplane veered to the right, which the pilot corrected by applying left rudder. Shortly after, the airplane "pulled hard to the right" and, despite the pilot's control inputs, exited the right side of the runway onto soft gravel and nosed over. The pilot added that he believed the right brake was “dragging significantly.” Postaccident examination of the airplane revealed that the fuselage was substantially damaged. Additional examination revealed that the fitting, where the brake line attaches to the upper portion of the brake caliper, was slightly bent outward toward the wheel assembly, which allowed for a portion of the brake line attached to the fitting to contact the inner wheel assembly, as shown in figure 1. Figure 1: View of the right main landing gear brake assembly. An area of scratched/displaced paint (about 3/4 to 1 inch wide and 1/4 inch tall) was observed on the wheel assembly. No additional damage was noted on the inboard portion of the wheel assembly. Additional damage was observed on the inboard side of the brake line sleeve fitting, as shown in figure 2. Figure 2: View of the right main landing gear brake assembly. The brake caliper and rotor were found unremarkable. When the brake line was pulled away from the wheel assembly, the wheel rotated freely by hand and was not restricted. However, when the brake line was not pulled away from the wheel assembly, it contacted the wheel assembly and rotated slightly before it stopped. It could not be determined when the caliper fitting was bent.
