# NTSB LAX06CA226: Barnard RV-6, N157ST, Groveland, CA, July 7, 2006 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: July 6, 2006, 19:30 local (Jul 7, 2006, 02:30 UTC) - Place: Groveland, CA - Coordinates: 37.861667, -121.17778 - Nearby events: https://openairdocs.org/map.md?lat=37.8617&lon=-121.1778&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report October 31, 2006 - Report: Approved by Office Director - Parties: Federal Aviation Administration - NTSB case key (mKey): 64064 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=LAX06CA226 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/64064/pdf - Page: https://openairdocs.org/ntsb/LAX06CA226 ## Probable cause the misjudged flare by the pilot that resulted in a hard bounced landing, and his failure to maintain directional control during the attempted recovery. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Hard landing, landing - flare/touchdown - flare - misjudged, pilot in command (cause) - Loss of control - on ground/water, landing - aborted - aborted landing - attempted, pilot in command - recovery from bounced landing - inadequate, pilot in command (cause) - directional control - not maintained, pilot in command (cause) - On ground/water collision with object, landing - aborted - object - fence - object - tree(s) ## Analysis The airplane veered off the runway during a bounced landing recovery, went through an airport perimeter fence, and collided with trees in a residential backyard. The pilot reported that he miscalculated the landing flare. The airplane landed hard and bounced into the air. The pilot added full power to abort the landing, but did not compensate for the p-factor. The airplane turned to the left, impacted the runway, traversed through the airport perimeter fence, and down an embankment where it came to rest in a residential backyard between trees. The pilot reported that there were no mechanical anomalies noted with the airplane that would have precluded normal operation. ## Factual narrative On July 6, 2006, at 1930 Pacific daylight time, an experimental Barnard RV-6, N157ST, veered off runway 9 during a bounced landing recovery and impacted trees at Pine Mountain Lake, Groveland, California. The owner/pilot operated the airplane under the provisions of 14 CFR Part 91, as a cross-country flight. The airplane sustained substantial damage. The pilot and one passenger were not injured, and there were no ground injuries. Visual meteorological conditions prevailed for the flight and no flight plan had been filed. The flight departed San Carlos Airport, San Carlos, California, at 1845. According to the pilot's written statement, he made a straight-in approach for runway 9 and miscalculated the flare. The airplane landed hard and bounced into the air. He added full power in an attempt to abort the landing; however, the airplane rolled to the left due to "P-factor torque." The airplane impacted the taxiway, slid down an embankment, and came to rest between two small trees. A deputy from Tuolumne County Sheriff's Department reported that the airplane came to rest 50 yards from the runway against a tree in the backyard of a residence. He located a skid mark on the taxiway surface, and noted that a portion of the airport perimeter fence had separated and was in the wreckage path. A pilot/witness who was airborne at the time reported that after the airplane touched down on the runway the right wing lifted into the air, which turned the airplane 90 degrees to the left. The airplane departed the runway, went through the airport perimeter fence, and hit a tree. ## Aircraft - Registration: [N157ST](https://openairdocs.org/deregistered/N157ST-2018-03-09), registration cancelled 2018-03-09, S/N 20075, built 1991 (OpenAirDocs) - Reported make and model: Barnard RV-6 - Registry model: [Barnard Stephen B RV-6](https://openairdocs.org/model/barnard-stephen-b-rv-6) (registry code 05608NB) (OpenAirDocs) - Registry engine: [Lycoming 0-360-A1D](https://openairdocs.org/engine/lycoming-0-360-a1d) (registry code 41504, reciprocating) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: 20075 - Engines: Lycoming IO-360-A1B6 reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Ronald Oler - Registered owner: Grindstaff Pamela J - Airworthiness certificate: Special, Experimental (Special) - Departed: SQL, San Carlos, CA - Destination: E45, Groveland, CA - Airport: E45, Pine Mountain Lake, runway 9, 3,625 × 50 ft, asphalt ## Flight crew As NTSB recorded them.

(-23) On 7/6/2006, at approximately 1930 PDT, RV-6 aircraft, N157ST, crashed during an attempted go-around from an aborted landing on runway 09, Pine Mountain… From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
