From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

N671T departed falcon field (ffz) in mesa Wednesday July 27, 2011SOMETIME in the afternoon. Upon arrival at Sedona Airport (sez), the aircraft entered the right hand traffic pattern for runway 21. Initial touch down was approximately 210 feet down runway 21 and approximately 20 feet left of the runway centerline. Within approximately 20 feet from the initial touch down point the right main gear collapsed followed by the collapse of the nose gear and left main gear. The aircraft then skidded along the runway drifting toward the right side of the runway. The aircraft then traveled approximately 600 feet until it exited the runway south / west of taxiway A2. The aircraft was piloted by privacy data omitted with one passenger, privacy data omitted. There were not injuries to either privacy data omitted or privacy data omitted.inspector gary hendrickson (iic) and privacy data omitted traveled to the aircraft to begin the on scene investigation. Initial touchdown marks were evident on the runway from all three landing gear. The first indication was from the right main gear. The skid mark indicated an immediate joggle to the right. Approximately 20 feet further, skid marks from both the left main and nose wheel were evident. Within approximately 6 feet from the initial skid mark made by the nose wheel, the pavement had a fresh impression approximately ½" deep. Immediately following this point, evidence of the nose, right and left main gear collapsing follow until the aircraft exited the runway. A later review of the aircraft maintenance records verified that this was in fact the aircraft total time. An initial inspection of the aircraft found all three landing gear collapsed and the aircraft was sitting on the collapsed nose gear assembly and the right main gear assembly. Further examination of the aircraft found the left main landing gear, inboard attach point was protruding through the lower wing skin. Damage of the outboard landing gear attach point was evident as pieces of the attach brackets were visible. Interviews with privacy data omitted brought to light that the aircraft had recently had maintenance performed on the right main landing gear. This work was performed by a company called "performance one" at falcon field. Interviews with privacy data omitted brought to light that the aircraft had recently had maintenance performed on the right main landing gear. This work was performed by a company called "performance one" at falcon field. Interviews of the technicians who had performed the repairs were conducted by inspector hendrickson as well as a review of the maintenance record entries. During discussions with the technician privacy data omitted, this aircraft had apparently a previous hard landing. The reason the aircraft was at performance one was that the right main landing gear outboard attach bracket pins had been sheared. Performance one had been contracted by privacy data omitted to perform the necessary repairs along with some unrelated maintenance. These repairs were completed on 6/15/2011 but the aircraft remained at performance one until the day of the accident for the completion of the other unrelated repairs. On 8/11/2011, arrangements were made with NTSB iic Mr. Thomas little and the Sedona Airport manager to have the aircraft lifted in order to examine the repairs made by performance one. Upon examination of the right main landing gear, no indications of any inadequate repairs could be found. On 08/24/2011 inspector hendrickson and privacy data omitted met with privacy data omitted and reviewed her pilot records. Pilot records indicated a large lapse in flying from 12/09/2006 until 04/15/2011 at which time a flight review was conducted. After interviewing privacy data omitted it was apparent that due to multiple factors including density altitude that this accident was the result of pilot error. This office is recommending a re-examination of privacy data omitted private pilot certificate.
