# NTSB SEA05LA101: Maule M-4-220C, N40318, Driggs, ID, May 21, 2005 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: May 21, 2005, 07:00 local (13:00 UTC) - Place: Driggs, ID - Coordinates: 43.741943, -111.097778 - Nearby events: https://openairdocs.org/map.md?lat=43.7419&lon=-111.0978&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report October 27, 2005 - Report: Approved by Office Director - Parties: SLC FSDO - NTSB case key (mKey): 61580 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=SEA05LA101 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/61580/pdf - Page: https://openairdocs.org/ntsb/SEA05LA101 ## Probable cause The pilot's failure to compensate for wind conditions, which resulted in a ground loop/swerve during the landing roll. A crosswind was a factor. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, landing - roll - weather condition - crosswind (contributing factor) - compensation for wind conditions - inadequate, pilot in command (cause) - Main gear collapsed, landing - roll - landing gear,main gear - overload - ground loop/swerve - inadvertent, pilot in command ## Analysis The pilot reported that the approach and wheel landing was normal, but shortly after touchdown the airplane encountered a "slight gust" of wind and veered left of runway centerline. The pilot stated he applied right rudder, however overcorrected and the airplane ground looped to the right. During the ground loop, the left main gear collapsed resulting in substantial damage to the wing assembly. The pilot reported that the winds at the time of the accident were from 170 degrees at 5-10 knots. ## Factual narrative On May 21, 2005, about 0700 mountain daylight time, a tail wheel equipped Maule M-4-220C, N40318, sustained substantial damage during the landing roll-out at Reed Memorial Airport, Driggs, Idaho. The airplane is registered to South Ford Motor Sports, Inc, and was being operated by the pilot as a visual flight rules (VFR) cross-country flight under the provisions of Title 14 CFR Part 91. The private pilot, and the three passengers aboard the airplane, were not injured. Visual meteorological conditions prevailed and no flight plan was filed for the flight that originated at Rexburg, Idaho, approximately 40 minutes prior to the accident. In a written statement to the National Transportation Safety Board (IIC), dated May 21, the pilot reported that the approach and wheel landing was normal, but shortly after touchdown the airplane encountered a "slight gust" of wind and veered left of runway centerline. The pilot stated he applied right rudder, however overcorrected and the airplane ground looped to the right. During the ground loop, the left main gear collapsed resulting in substantial damage to the wing assembly. The pilot reported the winds at the time of the accident were from 170 degrees at 5-10 knots. ## Aircraft - Registration: [N40318](https://openairdocs.org/deregistered/N40318-2013-05-14), registration cancelled 2013-05-14, S/N 2093C, built 1972 (OpenAirDocs) - Reported make and model: Maule M-4-220C - Registry model: [Maule M-4-220C](https://openairdocs.org/model/maule-m-4-220c) (registry code 5460114) (OpenAirDocs) - Registry engine: [Franklin 6V 350 series](https://openairdocs.org/engine/franklin-6v-350-series) (registry code 27043, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 2093C - Airframe hours: 1150 - Engines: Franklin 220 horsepower reciprocating - Damage: Substantial damage - Flight: Part 91 - Operator: Todd S.
