NTSB Final Report: Benson, AZ

December 19, 2022, Local

Registration:

N518DT

Aircraft:

Auto-Gyro Cavalon

Aircraft Damage:

Substantial

Defining Event:

Analysis

The pilot of the gyroplane reported that, typically after reaching a speed of about 45-50 mph during the takeoff roll and just before takeoff, the nosewheel becomes light. He stated that for the accident flight the nose became light as expected, but then suddenly dropped, and the nose gear contacted the runway hard. The gyroplane veered left, and he depressed full right rudder. The main rotor impacted the runway, and the gyroplane departed the runway and came to rest on its side, sustaining substantial damage to the fuselage, tail boom, and rotor system.

A postaccident examination of the flight controls revealed no anomalies. Further examination revealed the nose gear appeared to be bent aft and right and exhibited damage consistent with a hard impact. The runway surface exhibited witness marks consistent with a hard impact of the nose gear.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be: A loss of directional control on takeoff, which resulted in the collapse of the nose wheel strut and a runway excursion.

Findings

Personnel issues - Aircraft control - Pilot

Aircraft - Directional control - Not attained/maintained

Investigation Docket:

https://data.ntsb.gov/Docket?ProjectID=106555

 

The National Transportation Safety Board (NTSB), established in 1967, is an independent federal agency mandated by Congress through the Independent Safety Board Act of 1974 to investigate transportation accidents, determine the probable causes of the accidents, issue safety recommendations, study transportation safety issues, and evaluate the safety effectiveness of government agencies involved in transportation. The NTSB makes public its actions and decisions through accident reports, safety studies, special investigation reports, safety recommendations, and statistical reviews.

 

The Independent Safety Board Act, as codified at 49 U.S.C. Section 1154(b), precludes the admission into evidence or use of any part of an NTSB report related to an incident or accident in a civil action for damages resulting from a matter mentioned in the report. A factual report that may be admissible under 49 U.S.C. § 1154(b) is available here.
