Factual Information

On May 25, 1995, at 1134 central daylight time, a Hispano Aviacion HA-200, N212AM, was substantially damaged while landing at the Meacham Airport near Fort Worth, Texas. The airline transport rated pilot was not injured, while his passenger sustained minor injuries. Instrument meteorological conditions prevailed for the local personal flight. According to a Federal Aviation Administration (FAA) inspector, the pilot reported that the hydraulic actuator on the right main landing gear failed during initial takeoff climb, and the gear failed to retract. The pilot elected to execute a tower fly-by to verify the position of the landing gear prior to returning to land. The tower was unable to detect any anomalies with the landing gear, and the pilot returned for a full stop landing on Runway 16L. After rolling for over 2,000 feet during the landing rollout, the landing gear warning horn came on, followed about a second later by the collapse of the left main landing gear. The left wing impacted a runway sign on the left side of the runway, resulting in damage to the left wing spar. The pilot stated that all cockpit indications of a safe landing gear indication were present prior to touchdown. Post accident examination of the aircraft by the FAA inspector revealed that the hydraulic actuator for the right main landing gear failed for undetermined reasons.

Probable Cause and Findings

THE FAILURE OF THE HYDRAULIC ACTUATOR FOR THE RIGHT MAIN LANDING GEAR. A FACTOR WAS THE FALSE LANDING GEAR INDICATIONS PROVIDED BY THE LANDING GEAR INDICATING SYSTEM.
