Probable cause

The pilot’s inability to maintain directional control during landing for undetermined reasons, which resulted in a runway excursion.

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 stated that, upon landing, the airplane touched down on the runway centerline with light and variable wind conditions. The pilot recalled that the touchdown felt normal but that, during the landing roll, the airplane began to veer to the right. The pilot added full left rudder, but the airplane continued to veer off the runway surface and encountered large rocks located between the runway and taxiway. A postaccident operational check of the nosewheel steering system revealed no mechanical malfunctions or anomalies that would have precluded normal operation. The left nosewheel tire was not adequately inflated and was worn to the point at which the cord was exposed; the right nosewheel tire was within tolerances. Also, one-third of the rim was absent on the left nosewheel tire outer wheel half. The available evidence precluded a determination of whether the imbalance between the nosewheel tires contributed to the control problem on the runway. It could also not be determined if the left nosewheel tire damage occurred before the touchdown or as a result of the accident sequence.

Factual narrative

On March 14, 2020, about 1600 mountain standard time, a Raytheon Aircraft Company Hawker 800XP, N100AG, was substantially damaged when it was involved in an accident at Scottsdale Airport, Scottsdale, Arizona. The pilot and copilot were not injured. The airplane was being operated under the provisions of Title 14 Code of Federal Regulations Part 91 as a personal flight. The pilot stated that the flight departed from Roger, Arkansas, about 1315 central standard time (1215 mountain standard time). After an uneventful flight, the airplane touched down on the runway 21 centerline with light and variable wind conditions. The pilot recalled that the touchdown felt normal but that, during the landing roll, the airplane began to veer to the right. The pilot added full left rudder, but the airplane continued to veer off the runway surface and encountered large rocks located between the runway and taxiway. The airplane collided with runway lights and a sign, puncturing the left wing; both engines sustained foreign object damage from the rocks. The pilot thought that the loss of control was a result of the nosewheel steering system not being aligned correctly. A postaccident operational check of the steering system revealed no mechanical malfunctions or anomalies that would have precluded normal operation. The left-side nosewheel tire was not adequately inflated and was worn to the point at which the cord was exposed; the right-side tire was within tolerances. Also, one-third of the rim was absent on the nosewheel left-side outer wheel half. On the basis of the available evidence, a determination could not be made regarding whether the damage occurred before the touchdown or as a result of the accident sequence.
