# NTSB CHI03LA115: Stinson 108-1, N97930, Romeoville, IL, April 27, 2003 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: April 27, 2003, 17:00 local (22:00 UTC) - Place: Romeoville, IL - Coordinates: 41.608333, -88.094169 - Nearby events: https://openairdocs.org/map.md?lat=41.6083&lon=-88.0942&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report November 25, 2003 - Report: Approved by Office Director - Parties: Federal Aviation Administration - DuPage FSDO - NTSB case key (mKey): 56943 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI03LA115 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/56943/pdf - Page: https://openairdocs.org/ntsb/CHI03LA115 ## Probable cause The pilot not maintaining directional control during the landing rollout. A factor to the accident was the gusting crosswind. ## 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) - weather condition - gusts (contributing factor) - directional control - not maintained, pilot in command (cause) ## Analysis During the landing rollout the airplane encountered a wind gust that caused the airplane to weather vane. The pilot was unable to maintain directional control, which resulted in the airplane departing the runway. The aircraft was landing on runway 27 and the reported winds were 200 degrees magnetic at 15 knots with gusts to 21 knots. ## Factual narrative On April 27, 2003, at 1700 central daylight time, a Stinson 108-1, N97930, piloted by a private pilot, sustained substantial damage following a loss of directional control while landing on runway 27 (5,697 feet by 75 feet, dry/asphalt) at the Lewis University Airport (LOT), Romeoville, Illinois. Visual meteorological conditions prevailed at the time of the accident. The personal flight was operating under the provisions of 14 CFR Part 91 without a flight plan. The pilot reported no injuries. The local flight departed LOT at 1600 and was landing at the time of the accident. According to the pilot's written statement, when he was 5 miles from LOT he requested the current weather conditions over the Unicom frequency. The pilot reported he was told the winds were 180 degrees magnetic at 6-8 mph with gusts to 10 mph. The pilot stated he landed on runway 27 and during the landing rollout "a strong gust of wind started to weather vane the [aircraft] to the left." The pilot reported he applied right rudder, right brake, and retracted the flaps. The pilot stated the airplane continued to veer to the left, departing the runway surface. The right main landing gear collapsed, causing substantial damage to the airplane. A weather observation station, located at LOT, recorded the weather around the time of the accident as: Observation Time: 1705 cdt Wind: 200 degrees magnetic at 15 knots, Gusts 21 knots Visibility: 10 statute miles Sky Condition: Sky Clear Temperature: 25 degrees Celsius Dew Point: 02 degrees Celsius Pressure: 29.90 inches of mercury ## Aircraft - Registration: [N97930](https://openairdocs.org/deregistered/N97930-2013-02-19), registration cancelled 2013-02-19, S/N 108-930, built 1946 (OpenAirDocs) - Reported make and model: Stinson 108-1 - Registry model: [Stinson 108-1](https://openairdocs.org/model/stinson-108-1) (registry code 9230404) (OpenAirDocs) - Registry engine: [Franklin 6A4165 series](https://openairdocs.org/engine/franklin-6a4165-series) (registry code 27025, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 108-930 - Airframe hours: 1933 - Engines: Franklin 6A-150-B3 150 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, April 16, 2003, 3 hours before - Departed: LOT, Romeoville, IL - Destination: LOT, Romeoville, IL - Airport: LOT, Lewis University Airport, runway 27, 5,697 × 75 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.
