# NTSB LAX01LA187: Bennett Glastar, N241GS, Grass Valley, CA, May 19, 2001 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Limited investigation · Final report - Date: May 19, 2001, 14:45 local (21:45 UTC) - Place: Grass Valley, CA - Coordinates: 39.33913, -120.869995 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=39.3391&lon=-120.8700&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 2 minor - Status: Completed, report March 30, 2004 - Report: Approved by Office Director - Parties: Federal Aviation Administration - NTSB case key (mKey): 52310 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=LAX01LA187 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/52310/pdf - Page: https://openairdocs.org/ntsb/LAX01LA187 ## Probable cause The pilot's failure to arrest the excessive descent rate. A contributing factor was the gusty wind conditions. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - in flight, landing - flare/touchdown - weather condition - gusts (contributing factor) - airspeed - not maintained, pilot in command (cause) - descent - excessive, pilot in command - Hard landing, landing - flare/touchdown - Nose over, landing - roll ## Analysis According to the commercial pilot, he reduced power on final approach and then experienced an "extreme downdraft." He increased power in an attempt to arrest the excessive descent rate that ensued; however, he was unsuccessful. The airplane struck the ground and bounced back into the air. The pilot performed a go-around and conducted a low pass so that a person on the ground could examine the airplane. He was told that the nose landing gear was collapsed and the right wing was bent down approximately 20 degrees. The pilot performed another landing, during which the airplane skidded along the runway for 350 feet prior to veering off the side and nosing over. The closest weather reporting facility, which was 18 miles away, reported the wind at 14 knots with gusts to 23 knots. The pilot had accumulated a total of 32.2 hours of flight time in the accident airplane. The pilot indicated he could have landed with additional power and airspeed as a possible way of preventing the accident. ## Factual narrative On May 19, 2001, about 1445 Pacific daylight time, an experimental Bennett Glastar single engine airplane, N241GS, was substantially damaged when it nosed over after a hard landing at the Alta Sierra private airport near Grass Valley, California. The commercial pilot and his passenger received minor injuries. The airplane was registered to and operated by the pilot under the provisions of 14 CFR Part 91. Visual meteorological conditions prevailed for the personal flight, and a flight plan had not been filed. The local flight originated from Auburn, California, and was destined for Alta Sierra. The pilot was returning to Alta Sierra after a local flight to Auburn for refueling. According to the pilot's written statement, they were approaching the south end of runway 01 when he reduced engine power for landing. He reported that at the same time, the flight "experienced an extreme downdraft and fell vertically onto the runway at the [runway] numbers." The pilot attempted to apply power to arrest the descent rate, but was unable to do so in time, indicating the throttle control was in the full power position at the time the airplane struck the ground. The airplane bounced back into the air with the right wing "dipping down approximately 20 degrees" and the nose veering to the right. The pilot stabilized the airplane in ground effect and elected to conduct a go-around. He conducted a low pass so a person on the ground could examine the undercarriage, which is when he learned the nose landing gear was bent aft 90 degrees and the right wing was bent down approximately 20 degrees. The pilot landed the airplane a second time, and it skidded approximately 350 feet before veering off the side of the runway, where it nosed over. The airplane came to rest inverted. At 1455, the Beale Air Force Base (BAB) weather observation facility, located 18 miles west of the accident site, reported the wind from the northwest at 14 knots with gusts to 23 knots. According to the pilot, the Alta Sierra airport did not have weather reporting capabilities. The pilot built the experimental airplane and had flown it 32.2 hours. The pilot reported having logged a total of 1,178.6 hours of flight time. In the submitted Pilot/Operator Aircraft Accident Report (NTSB Form 6120.1/2), under the section titled, "Recommendations (How Could This Accident Have Been Prevented)," the pilot responded with, "possibly by landing with additional power and airspeed." ## Aircraft - Registration: [N241GS](https://openairdocs.org/deregistered/N241GS-2001-07-09), registration cancelled 2001-07-09, S/N 5113 (OpenAirDocs) - Reported make and model: Bennett Glastar - Registry model: [Bennett Gary R GLASTAR](https://openairdocs.org/model/bennett-gary-r-glastar) (registry code 056102H) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: 5113 - Airframe hours: 36 - Engines: Lycoming O-360-A1F6 180 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Gary R.

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.
