## Analysis

THE ACFT WAS ON AN FAA CERTIFICATION FLT (EXPERIMENTAL). DURING THE RECOVERY PHASE, A NON-TYPE RATED FAA PLT WAS IN THE L SEAT & THE PIC WAS IN THE R SEAT. WHILE DESCENDING, A DUCT FAIL LGT & A LEADING EDGE OVERHEAT LGT CAME ON. THE PIC TOOK CORRECTIVE ACTION. THE FAA PLT MADE AN ILS APCH TO RWY 22 WHICH WAS WET. THE APCH WAS MADE WITH THE L ENG AT HI IDLE. THE THRUST REVERSERS WERE NOT ARMED FOR THE LANDING. A TOUCHDOWN WAS MADE ABOUT 2000' DOWN THE RWY & SPOILERS WEREDEPLOYED. WHEN THE FAA PLT REALIZED HE DID NOT HAVE REVERSE THRUST, HE TRIED SLOWING THE ACFT WITH BRAKES; HOWEVER, THE L BRAKE WAS INOP. THE PIC TOOK CONTROL & CYCLED THE ANTI-SKID, BUT STILL HAD NO L BRAKING ACTION. SUBSEQUENTLY, THE ACFTRAN OFF THE END OF THE RWY & THE NOSE GEAR COLLAPSED IN MUDDY TERRAIN. AN INVESTIGATION REVEALED THAT DURING MAINTEN- ANCE, THE SPEED SENSOR HARNESSES FOR THE L MAIN GEAR WERE REVERSED WHICH ELIMINATED ANY BRAKING TO THE L BRAKE WHILE THE ANTI-SKID WAS ON.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19840402008289A](https://openairdocs.org/incident/19840402008289A), Apr 2, 1984: Cndair CL6001A11, Little Rock, AR, Substantial damage. Antiskid speed sensor harness had been improperly installed on left main braking system. Airplane ran off runway.

From the NTSB's public API. 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. Compare the reported make and model.
