Burr Express 2000 RG, N44508: Accident occurred May 29, 2015 at Glendale Municipal Airport (GEU), Maricopa County, Arizona

Aviation Accident Final Report - National Transportation Safety Board: https://app.ntsb.gov/pdf

NTSB Identification: WPR15LA179
14 CFR Part 91: General Aviation
Accident occurred Friday, May 29, 2015 in Glendale, AZ
Probable Cause Approval Date: 05/23/2017
Aircraft: BURR EXPRESS 2000 RG, registration: N44508
Injuries: 2 Uninjured.

NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The private pilot reported that, following a normal landing in the experimental amateur-built airplane, he applied beta thrust to decelerate the airplane and lightly applied the brakes. Suddenly, the left main landing gear collapsed, and the airplane swerved to the left. The airplane departed the runway surface and the left wing impacted a runway sign. Postaccident examination revealed that the left main landing gear actuator heim rod failed where the threads met the rod end; however, the rod was not made available for further examination, and the reason for the landing gear collapse could not be determined.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
A collapse of the left main landing gear for reasons that could not be determined based on the available information.

The National Transportation Safety Board did not travel to the scene of this accident.

NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

On May 29, 2015, about 1542 mountain standard time, a Burr Express 2000 RG, N44508, experienced a landing gear collapse during the landing roll at Glendale Municipal Airport (GEU) in Glendale, Arizona. The private pilot and one passenger were uninjured, and the airplane sustained substantial damage to the rudder and elevators. The airplane was registered to, and operated by, the pilot under the provisions of 14 Code of Federal Regulations Part 91 as a personal flight. Visual meteorological conditions prevailed and no flight plan was filed. The flight departed from GEU at about 1500.

The pilot reported that he landed the airplane onto the runway normally. He applied beta thrust to decelerate the airplane and started to brake lightly. Suddenly, the left main landing gear collapsed and the airplane swerved to the left. The airplane departed the runway surface and the left wing impacted a runway sign. It traversed along the dirt when the right landing gear collapsed and the tail impacted the ground before sliding to a rest. 

During a postaccident examination by a Federal Aviation Administration Inspector it was revealed that the left main landing gear actuator heim rod failed where the threads meet the rod end. Given the location of the heim rod, the inspector was unable to view the fracture surface while the component was installed on the airplane. In addition, the inspector noted that the hydraulic line to the gear actuator was ripped. 

The National Transportation Safety Board Investigator-in-charge attempted to obtain the heim rod for further examination, however, the pilot had already repaired the airplane and the part was no longer available.
