# NTSB CHI93LA373: Beech 18-C45G, N80323, Jeffersonville, IN, September 20, 1993 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: September 20, 1993, 19:40 local (23:40 UTC) - Place: Jeffersonville, IN - Location: 38.3666° N, 85.7381° W: Placed by OpenAirDocs at CLARK RGNL (JVY), within about a mile (OpenAirDocs) - Nearby events: https://openairdocs.org/map.md?lat=38.3666&lon=-85.7381&mi=10 - Phase of flight: [Approach](https://openairdocs.org/ntsb-phases/500) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report July 25, 1994 - Report: Approved by Office Director - NTSB case key (mKey): 9324 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI93LA373 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/9324/pdf - Page: https://openairdocs.org/ntsb/CHI93LA373 ## Probable cause the mechanical binding of the landing gear extension mechanism. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Airframe/component/system failure/malfunction, approach - vfr pattern - downwind - landing gear,normal retraction/extension assembly - binding(mechanical) (cause) - maintenance,lubrication - inadequate, other maintenance personnel - gear extension - attempted, pilot in command - Gear collapsed, landing - roll ## Analysis THE PILOT STATED WHEN HE ATTEMPTED TO EXTEND THE LANDING GEAR WITH THE GEAR SELECTOR IT DID NOT EXTEND. HE EXTENDED THE GEAR MANUALLY, CRANKING UNTIL HE FELT RESISTANCE, BUT DID NOT RECEIVE A GEAR DOWN AND LOCKED INDICATOR IN THE COCKPIT. GROUND PERSONNEL TOLD THE PILOT THE LANDING GEAR APPEARED TO BE EXTENDED. THE PILOT MADE A NORMAL APPROACH AND LANDING. DURING THE LANDING ROLL THE PILOT APPLIED THE BRAKES AND THE MAIN LANDING GEAR COLLAPSED. INVESTIGATION REVEALED THE LANDING GEAR SLIDE TUBES LACKED LUBRICATION AND THE RIGHT MAIN GEAR SLIDE TUBE WAS CORRODED. THE AIRPLANE HAD FLOWN 16.25 HOURS SINCE AN ANNUAL INSPECTION WAS PERFORMED ON NOVEMBER 3, 1992. ## Factual narrative On September 20, 1993, approximately 1940 hours eastern daylight time, a Beech BE18-C45G, N80323, piloted by the commercial pilot/airplane owner, sustained substantial damage when the landing gear collapsed during the landing roll at Jeffersonville, Indiana. The pilot, the sole occupant, reported no injuries. Visual meteorological conditions prevailed for the local flight, no flight plan was filed. The flight operated under 14 CFR Part 91, and originated from Jeffersonville, Indiana, approximately 1930 hours. The pilot stated he had performed two takeoffs and landings without incident. When he attempted to extend the landing gear for the third landing, it did not extend. He reported after cycling the landing gear handle several times, he utilized emergency landing gear extension methods to lower the gear. The pilot stated he cranked the gear down until he felt resistance. The landing gear indicator flags did not indicate the gear was down and locked. The pilot requested and received verification from ground personnel that the landing gear appeared to be extended. He stated he used normal approach procedures and airspeeds, and the touchdown and roll out seemed normal. The pilot reported when he "...made a light brake application to finish slowing...the landing gear folded back into the wheel wells." Postaccident inspection revealed the main landing gear slide tubes were lacking lubrication. The right main gear slide tube was corroded. Impact damage precluded a complete evaluation of the electrical system, but the electrical landing gear motor was capable of normal operation. An FAA Inspector statement is appended. The most recent maintenance performed on the airplane was an Annual Inspection completed November 3, 1992. The airplane operated 16.25 hours since that inspection. ## Aircraft - Registration: [N80323](https://openairdocs.org/aircraft/N80323), registered now, S/N AF-1, built 1957 (OpenAirDocs) - Reported make and model: BEECH 18-C45G - Registry model: [Beech C-45G](https://openairdocs.org/model/beech-c-45g) (registry code 1151014) (OpenAirDocs) - Registry engine: [Pratt & Whitney R-985 series](https://openairdocs.org/engine/pratt-whitney-r-985-series) (registry code 52008, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: AF-1 - Airframe hours: 5362 - Engines: P&W R-985 450 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Crites, Kenneth J. - Registered owner: Long, Earl V. - Airworthiness certificate: Standard, Normal - Last inspection: Annual, November 3, 1992, 16 hours before - Airport: JVY, Clark County, runway 18, 5,500 × 100 ft, asphalt ## Flight crew As NTSB recorded them.
