# NTSB LAX01LA203: Mooney M20J, N4235H, Jackson, CA, June 9, 2001 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: June 9, 2001, 11:00 local (18:00 UTC) - Place: Jackson, CA - Coordinates: 38.366664, -120.783332 - Nearby events: https://openairdocs.org/map.md?lat=38.3667&lon=-120.7833&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report November 28, 2001 - Report: Approved by Office Director - Parties: FEDERAL AVIATION ADMINISTRATION - NTSB case key (mKey): 52429 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=LAX01LA203 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/52429/pdf - Page: https://openairdocs.org/ntsb/LAX01LA203 ## Probable cause Failure of the pilot to maintain proper airspeed for landing and airplane control with an existing crosswind. A contributing factor was the distraction of the pilot by a yelling passenger. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Hard landing, landing - flare/touchdown - airspeed(vs) - not maintained, pilot in command (cause) - Loss of control - on ground/water, landing - flare/touchdown - aircraft control - not maintained, pilot in command (cause) - weather condition - crosswind (cause) - emotional reaction, passenger (contributing factor) - diverted attention, pilot in command (contributing factor) - ground loop/swerve - encountered, pilot in command - Nose gear collapsed, landing - landing gear,nose gear - fractured - landing gear,nose gear - overload ## Analysis The airplane landed hard, porpoised down the runway, departed the runway, ground looped, and came to rest in a landfill area on its main landing gear. The airplane had flown for about an hour the day of the accident to three different airports with no discrepancies noted. Once established on final approach, the pilot observed the windsock indicating a crosswind condition, and felt the drift of the airplane to the left. After slowing the airplane and correcting for the crosswind, he did not recheck his airspeed to make sure he had the appropriate airspeed for landing. The airplane landed hard and short of the runway, and porpoised two times down the runway. The pilot added power in an attempt to regain airplane control. The airplane started to depart to the left of the runway, and he simultaneously became distracted by his passenger who started yelling. The airplane traveled approximately 150 feet before the nose landing gear collapsed, and an additional 450 feet before coming to rest in a landfill area. ## Factual narrative On June 9, 2001, at 1100 hours Pacific daylight time, a Mooney M20J, N4235H, ground looped on the landing roll out from runway 19 at the Westover Field Amador County Airport, Jackson, California. The airplane was operated by the owner/pilot under the provisions of 14 CFR Part 91, and sustained substantial damage. The private pilot and a pilot rated passenger were not injured. Visual meteorological conditions prevailed for the local area flight that departed at 1000. A flight plan had not been filed. The flight was scheduled to terminate at the Westover airport. The Safety Board investigator interviewed the pilot. The pilot stated that the landing was a little too fast. After touchdown the airplane started to porpoise down the runway. A crosswind pushed the airplane to the left of the runway. The left wheel caught on the side of the runway, the airplane ground looped, spun around, and came to rest on its main landing gear. In the pilot's written statement to the Safety Board, he stated that the purpose of the flight was a round robin to three other airports. He departed from Westover at 1000, and stopped at the Calaveras County airport (0O3), the Columbia airport (O22), and the Pine Mountain Lake airport (Q68), all located in California. He departed from Q68 at 1045 and flew direct to Westover. The pilot reported that Westover airport is located on top of a hill and runway 19 has a significant upslope. He entered the pattern on the 45 for a left downwind for landing. After he turned on final approach, he observed the windsock indicating a crosswind, and felt the right to left drift of the airplane. The pilot slowed the airplane to 80 knots for the approach and made the crosswind correction. He stated that he did not pay "sufficient attention to slowing the airplane over the threshold which should have been 70 knots." The airplane landed hard about 400 feet from the approach threshold. The pilot estimated his airspeed to be about 75 knots. The airplane porpoised two times down the runway. He added power to attempt to straighten, and maintain control of the airplane. The pilot stated that two things happened simultaneously; his passenger started yelling which distracted him, and the crosswind pushed the airplane to the left of centerline towards the runway edge. The left main gear departed the runway surface and the airplane departed the runway. After traveling approximately 500 feet from the runway the airplane came to rest in a shallow landfill embankment. He stated there were no discrepancies noted with the round robin flight. ## Aircraft - Registration: [N4235H](https://openairdocs.org/aircraft/N4235H), registered now, S/N 24-0676, built 1978 (OpenAirDocs) - Reported make and model: Mooney M20J - Registry model: [Mooney M20J](https://openairdocs.org/model/mooney-m20j) (registry code 5870219) (OpenAirDocs) - Registry engine: [Lycoming I0360 series](https://openairdocs.org/engine/lycoming-i0360-series) (registry code 41515, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 24-0676 - Airframe hours: 2900 - Engines: Lycoming IO-360-A3B6D 200 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Garth W.

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.
