Accident Details
On March 21, 2010, at approximately 1905 Pacific daylight time, a Beech 58P, registration N580TC, experienced a collapse of all three landing gear during the landing rollout at Santa Barbara Municipal Airport (SBA) in Santa Barbara, California. The airplane was substantially damaged. The airline transport pilot and four passengers were uninjured. Visual meteorological conditions prevailed at the time, and no flight plan was filed. The cross-country flight, conducted under 14 Code of Federal Regulations Part 91, had departed San Jose International Airport (SJC) about 1745 with SBA as its destination.
Pilot Report
In a telephone interview with the NTSB investigator-in-charge shortly after the accident, the pilot reported that during final approach he observed three green lights, indicating that all landing gear were down and locked. He added that he did not hear a landing gear warning horn. Upon touchdown and after rolling out between 500 and 1,000 feet down the runway, the nose gear collapsed, followed by the left and right main landing gear. The airplane came to rest on the runway, just to the right of the centerline.
Post-Accident Examination
A Federal Aviation Administration (FAA) airworthiness inspector conducted a post-accident examination of the airplane. The inspector reported that both main landing gear inner doors were damaged, but neither outer door sustained visible damage. The forward pressure bulkhead was substantially damaged. During a subsequent post-accident examination and repair, a certificated FAA airframe and powerplant mechanic reported that he did not identify a mechanical failure or malfunction that could be attributed to the landing gear collapse.
