# NTSB LAX97LA237: Cessna 172N, N738ET, Joshua Tree, CA, July 7, 1997 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Limited investigation · Final report - Date: July 7, 1997, 15:37 local (22:37 UTC) - Place: Joshua Tree, CA - Coordinates: 34.14933, -116.270683 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=34.1493&lon=-116.2707&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 3 minor - Status: Completed, report December 31, 1998 - Report: Approved by Office Director - NTSB case key (mKey): 29832 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=LAX97LA237 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/29832/pdf - Page: https://openairdocs.org/ntsb/LAX97LA237 ## Probable cause failure of the pilot to adequately judge the wind direction and to select the correct runway, which resulted in a downwind landing; and his failure to go around, while there was sufficient runway remaining. The tailwind, fence, and ditch were related factors. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Overrun, landing - roll - weather condition - tailwind (contributing factor) - wind information - misjudged, pilot in command (cause) - wrong runway - selected, pilot in command (cause) - go-around - not performed, pilot in command (cause) - On ground/water collision with object, landing - roll - object - fence (contributing factor) - On ground/water encounter with terrain/water, landing - terrain condition - ditch (contributing factor) - Nose over, landing ## Analysis The pilot reported that while he was preparing to land, he was 'unable to determine any substantial wind by ground observation or from any effect on the path of the aircraft over terrain.' He stated that he then made a low pass over runway 6 and observed the windsock to show a moderate crosswind from the north. The pilot then made an approach, but landed long and with a slight bounce. The aircraft overran the runway and collided with a fence and a berm, then nosed over. The pilot further reported that after the accident, he observed the windsock to show a tailwind for landing on runway 6. Also, he was told that the winds were coming from 240 degrees at approximately 12 knots at the time of the accident. He stated that he 'misjudged the stopping distance and failed to initiate a go-around.' ## Factual narrative On July 7, 1997, at 1537 hours Pacific daylight time, a Cessna 172N, N738ET, overran runway 6 on landing at the Joshua Tree, California, airport and collided with a fence and a berm, then nosed over. The aircraft was rented by the pilot from Morcom Aviation Services of Everett, Washington, for a cross-country personal flight to Joshua Tree. Visual meteorological conditions prevailed and no flight plan was filed. The aircraft sustained substantial damage. The private pilot and his two passengers sustained minor injuries. The flight originated at Santa Monica, California, on the day of the accident at 1415. In his written statement, the pilot reported that while he was setting up the approach into the Joshua Tree Airport, he was "unable to determine any substantial wind by ground observation or from any effect on the path of the aircraft over terrain." He stated that after determining that there was no other traffic in the area, he made a low pass over runway 6 and observed the windsock to show a moderate crosswind from the north. The pilot reported that after going around, he made a normal approach but landed long and with a slight bounce. He then overran the runway and collided with a fence and a berm, then nosed over. The pilot further reported that after the accident he observed the windsock to show a tailwind for landing on runway 6, and he was told that the winds were coming from 240 degrees at approximately 12 knots at the time of the accident. He stated that he "misjudged the stopping distance and failed to initiate a go-around." ## Aircraft - Registration: N738ET (not matched to a registry record) - Reported make and model: Cessna 172N - Category: Airplane - Serial number: 17269926 - Airframe hours: 9813 - Engines: Lycoming O-320-H2AD 160 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Morcom Aviation Services, Inc - Airworthiness certificate: Standard, Normal - Last inspection: Annual, June 25, 1997, 20 hours before - Departed: SMO, SANTA MONICA, CA - Destination: L80 - Airport: L80, Joshua Tree, runway 6, 2,493 × 50 ft, asphalt ## Flight crew As NTSB recorded them.

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.
