# NTSB LAX06CA216: Eklund Thorp T-18, N181RE, San Andreas, CA, June 27, 2006 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Data collection · Final report - Date: June 27, 2006, 09:30 local (16:30 UTC) - Place: San Andreas, CA - Coordinates: 38.200321, -120.620918 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=38.2003&lon=-120.6209&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 1 minor - Status: Completed, report October 3, 2006 - Report: Approved by Office Director - Parties: Federal Aviation Administration - NTSB case key (mKey): 63996 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=LAX06CA216 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/63996/pdf - Page: https://openairdocs.org/ntsb/LAX06CA216 ## Probable cause the pilot's misjudged airspeed and distance during the approach, and his failure to initiate a timely go-around, which resulted in a landing overrun. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Overrun, landing - roll - distance/speed - misjudged, pilot in command (cause) - go-around - not performed, pilot in command (cause) - proper touchdown point - not attained, pilot in command (cause) - On ground/water encounter with terrain/water, landing - roll - terrain condition - ground - Nose over, landing - roll ## Analysis The airplane landed long and fast, overran the departure end of the runway, and nosed over. On final approach the airplane's speed was high. The pilot extended full flaps to slow down. The airplane overshot the numbers at the approach end of the runway, but the pilot continued his approach and touched down near midfield. Brake application was inadequate to stop the airplane due to its high speed and the runway distance remaining. The airplane overran the departure end of the runway and nosed over. The pilot stated that the airplane and engine had no mechanical failures or malfunctions during the flight. ## Factual narrative On June 27, 2006, about 0930 Pacific daylight time, an experimental Eklund Thorp T-18, N181RE, overran the runway at Calaveras County-Maury Rasmussen Field, San Andreas, California. The pilot/owner was operating the airplane under the provisions of 14 CFR Part 91. The commercial pilot, the sole occupant, sustained minor injuries; the airplane sustained substantial damage. The cross-country personal flight departed Stockton Metropolitan Airport, Stockton, California, about 0900, with a planned destination of San Andreas. Visual meteorological conditions prevailed, and no flight plan had been filed. The pilot submitted a written report. He was flying to San Andreas to meet a flight instructor for a biennial flight review. He arrived 5 miles west of the Calaveras County airport and reported his landing intentions and altitude on the Universal Communications (UNICOM) frequency. Two other aircraft were in the area. The pilot flew over the field then turned back toward the airport, announcing his intention to enter right downwind for runway 31. As he approached his turn to base, the pilot of one of the other aircraft announced that he had visual contact. The pilot completed his turns to right base and final for runway 31. His speed was higher than normal and he tried to slow down by extending full flaps. It became obvious to him that he would overshoot the numbers at the approach end of the runway, but he continued his approach and touched down near midfield. Brake application was inadequate to stop the airplane due to its high speed and the runway distance remaining. The airplane overran the departure end of the runway, skidded, nosed over, and came to rest inverted. The pilot stated that the airplane and engine had no mechanical failures or malfunctions during the flight. ## Aircraft - Registration: [N181RE](https://openairdocs.org/aircraft/N181RE), registered now, S/N 195, built 1996 (OpenAirDocs) - Reported make and model: Eklund Thorp T-18 - Registry model: [Eklund Richard D THORP T-18](https://openairdocs.org/model/eklund-richard-d-thorp-t-18) (registry code 05603DP) (OpenAirDocs) - Registry engine: [Lycoming O&VO-360 series](https://openairdocs.org/engine/lycoming-o-vo-360-series) (registry code 41514, reciprocating) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: 195 - Airframe hours: 324 - Engines: Lycoming O-360 180 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Richard Eklund - Airworthiness certificate: Special, Experimental (Special) - Last inspection: Condition, June 1, 2006 - Departed: KSCK, Stockton, CA - Destination: KCPU, San Andreas, CA - Airport: CPU, Calaveras County, runway 31, 3,603 × 60 ft, asphalt ## Flight crew As NTSB recorded them.

(-23) Pilot stated his approach was high and fast. He then landed FAR down the runway, ran off the runway, and the aircraft flipped over. 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. Compare the reported make and model. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/). It is not affiliated with the FAA or the NTSB.
