Aviation Accident Summary CEN20LA084

St Louis, MO, USA

Aircraft #1

N405PT

Beech 200

Analysis

The pilot departed on a cross-country flight; during departure, the pilot heard the main landing gear retract but the main landing gear indication remained red, indicating the gear were in transit. During the approach to the destination airport, the pilot heard the main landing gear extend but did not see three green landing gear indications. The pilot visually confirmed the main landing gear were extended, and the controller confirmed during a low pass that all three landing gear were extended. The pilot completed the emergency landing gear extension procedure and felt resistance on the handle, consistent with the landing gear being extended, so he believed that there was a wiring issue with the landing gear indicator. The pilot reported that he attempted to slow the airplane as much as possible before touching down and that the landing seemed normal until the airplane veered hard to the left. The pilot attempted to correct with the application of right rudder and right brake; however, the airplane departed the runway, resulting in substantial damage to the fuselage, including the collapse of all three landing gear. Skid marks and propeller strike indications on the runway were consistent with the nose landing gear collapsing before departing the runway surface. Postaccident examination of the airplane revealed that the nose landing gear upper drag brace, the nose landing gear actuator, and the nose landing gear steering links were all fractured during the accident sequence. However, the damage to the nose landing gear assembly precluded further testing, and investigators were not able to determine which component failed first, so the reason for the loss of control on landing and subsequent gear collapse could not be determined from the available information.

Factual Information

On February 6, 2020, about 1400 central standard time, a Beech Super Kingair B200, N405PT, was substantially damaged when it was involved in an accident near St. Louis, Missouri. The commercial pilot and passenger were not injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. The pilot stated that this was the first flight after a phase maintenance inspection was completed on the airplane. He had just picked the airplane up from the maintenance facility and intended to fly it to Spirit of St. Louis Airport (SUS), St. Louis, Missouri. Upon departure from North Little Rock Municipal Airport (ORK), North Little Rock, Arkansas, the pilot heard the main landing gear retract but the gear indication light remained red, indicating a gear in-transit status. The pilot reported that he had experienced this anomaly before and was not concerned. During the approach to SUS, the pilot heard the main landing gear extend but did not receive three green landing gear indication lights. The pilot visually confirmed that the main landing gear were extended but could not see the nose landing gear. He requested a low pass in front of the air traffic control tower who confirmed all of the landing gear appeared to be down. The pilot went through the emergency landing gear extension procedure to manually extend the landing gear and felt resistance on the handle, consistent with the landing gear being extended. The pilot stated that at this point he believed that there was a wiring issue with the landing gear indicator light. The pilot explained that he attempted to slow the airplane down as much as possible before touching down and the landing seemed normal until the airplane veered hard to the left. He tried to correct with right rudder input, but it had no effect, so he used right brake to steer the airplane back to the right. The airplane turned hard right, exited the runway, and the airplane slid left wing first into the grass. The airplane sustained substantial damage to the fuselage structure. According to the Federal Aviation Administration (FAA) aviation safety inspector (ASI) who responded to the accident, the airplane came to rest with all three landing gear collapsed. The landing gear handle was in the "DOWN" position. There were skid marks and propeller strike indications on the runway leading to the point that the airplane left the pavement; consistent with the nose landing gear collapsed prior to departing the runway surface. The FAA ASI reported that the nose landing gear upper drag brace, the nose landing gear actuator, and the nose landing gear steering links were all fractured during the accident sequence. The damage to the nose landing gear assembly precluded further texting and investigators were not able to determine which component failed first.

Probable Cause and Findings

The pilot’s loss of directional control and the subsequent nose landing gear collapse of for undetermined reasons.
