# NTSB MIA00LA270: Douglas DC-3, N12907, Charlotte, NC, September 26, 2000 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: September 26, 2000, 06:35 local (10:35 UTC) - Place: Charlotte, NC - Coordinates: 35.230403, -80.909278 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=35.2304&lon=-80.9093&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report July 2, 2001 - Report: Approved by Office Director - NTSB case key (mKey): 50337 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=MIA00LA270 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/50337/pdf - Page: https://openairdocs.org/ntsb/MIA00LA270 ## Probable cause the right main brake locked after touchdown causing the airplane to yaw and depart the runway, resulting in the landing gear collapsing. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Airframe/component/system failure/malfunction, landing - flare/touchdown - landing gear,normal brake system - locked (cause) - aircraft control - not maintained, pilot in command - Nose over, landing - roll ## Analysis After an approach to runway 5, and touched down at 85 knots, the airplane yawed right, exited the runway, the right main landing gear collapsed, and the airplane nosed over. Examination of the airplane revealed that a right main wheel brake had locked up, and the landing gear had collapsed. Inspection of the right main landing gear assembly and all associated components could not provide any determination as to what caused the main wheel brake to lockup. The brake assembly was broken down into its component parts and inspected. No evidence of malfunction could be detected. No contamination of the hydraulic fluid was evident. ## Factual narrative On September 26, 2000, about 0635 eastern daylight time, a Douglas DC-3, N12907, nosed over during the landing roll at Douglas International Airport, Charlotte, North Carolina. Visual meteorological conditions prevailed at the time, and an instrument flight plan was filed for the 14 CFR Part 91 positioning flight. The airplane was substantially damaged. The airline transport-rated pilot and commercial-rated copilot reported no injuries. The flight had departed Anderson, North Carolina, en route to Charlotte at 0545. The pilot told the FAA, "...that he had positive gear down and locked indications and touched down at 85 knots. The airplane yawed right and nosed over, the aircraft was out of control at this point." Examination of the airplane by the FAA revealed that a right main wheel brake had locked up, and the landing gear had collapsed. According to the FAA inspector's statement, "...a pronounced and uniform skid mark from the point of initial brake lockup to a point approximately 2,500 feet from the landing threshold was evident. After exiting the runway, the right main landing gear collapsed." Inspection of the right main landing gear assembly and all associated components could not provide any insight as to what caused the main wheel brake to lockup. The brake assembly was broken down into its component parts and inspected. No evidence of malfunction could be detected. No contamination of the hydraulic fluid was evident. ## Aircraft - Registration: N12907 (not matched to a registry record) - Reported make and model: Douglas DC-3 - Category: Airplane - Serial number: 27187 - Airframe hours: 17425 - Engines: P&W 1830-92 1200 horsepower reciprocating - Damage: Substantial damage - Flight: Positioning, Part 91 - Registered owner: Saber Cargo Airlines Inc. - Airworthiness certificate: Standard, Normal - Last inspection: AAIP, September 23, 2000, 14 hours before - Departed: 6W4, ANDERSON, NC - Destination: CLT - Flight plan: IFR - Airport: CLT, Charlotte Douglas, runway 5, 7,502 × 150 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.
