From the Wikipedia article
Aerotransportes Entre Rios Flight 501/90 (flight number: RS501/90) was an intercontinental cargo flight of the Argentine cargo airline Aerotransportes Entre Rios on 27 September 1975. On that day a Canadair CC-106 Yukon, which was to fly to Panama City, crashed on takeoff from Miami International Airport. Six of the ten people on board the aircraft were killed in the accident.
Accident sequence
Before departure the crew filed a flight plan stating that the flight to Panama City would be conducted under instrument flight rules. At 05:55 the aircraft received taxi clearance for runway 27L at Miami Airport. The takeoff run began at around 6:00 in the morning, in darkness (sunrise in Miami that day was at 07:11), in visual meteorological conditions. The takeoff run initially appeared normal, but on reaching rotation speed the aircraft did not lift off. Two to three seconds later the captain initiated a rejected takeoff by activating the thrust reversers and applying the wheel brakes. The aircraft overran the end of the runway, collided with the ILS antennas and broke through the airport fence. The aircraft rolled 879 feet beyond the runway across a lawn before it rolled over the Perimeter Road outside the airport and fell into a drainage canal located beyond it, between the Inner Perimeter Road and the Outer Perimeter Road. In the process the forward fuselage section was torn off and slid across the Outer Perimeter Road, where it collided with a parked VW bus, whose occupant was injured. The aircraft caught fire after the impact and burned out completely.
Investigation and cause
Causes
The National Transportation Safety Board (NTSB) investigated the incident. The accident report was published on 10 March 1976. In it the investigators determined that the cause of the accident was the execution of the takeoff run without first removing a makeshift wooden control lock on the elevator, which was attached to the right Flettner tab. The elevator therefore could not be moved into the position required for lift-off.
The control lock was not one of the aircraft's certified assemblies. The CL-44 was equipped at the factory with a hydraulic control lock system, but after an air accident in 1970 this was either modified or deactivated on most aircraft of this type, after it had been found that the accident aircraft had crashed after the control lock system had activated itself in flight. Aerotransportes Entre Rios was one of the airlines that deactivated the system. It used makeshift external wooden control locks, which were attached to the control surfaces by the crew between flights.

- One occurrence in two sources, merged: the Wikipedia article "Aerotransportes Entre Rios Flight 501/90" and NTSB case NTSB19750927P061438, matched by the same aircraft registration and date. For this US event the NTSB's values are used where the two differ; each value names its source.
- From NTSB's 1962-1981 archive (PRE1982), which holds at most a short remark (98 characters, abbreviated) instead of a narrative; the accident type, phase of flight, causes and conditions are NTSB's codes, decoded as the archive defines them.
- Reviewed means this record passed the site's consistency check, not that it was checked against a narrative or report - there is none to check against.
- The operation category is mapped from the archive's operator and operation codes and has not been reviewed.
