## Analysis

N101AA WAS OPERATING AS AMERICAN FLT 192. FLT 192 WAS ORIGINALLY CLEARED TO LAND ON RWY 21R; HOWEVER, A PRECEEDING ACFT HAD A LANDING GEAR PROBLEM, SO FLT 192 WAS CLEARED TO LAND ON RWY 21C, INSTEAD. THE COPLT, WHO WAS FLYING THE ACFT, MADE A SIDE-STEP MANEUVER TO LAND ON RWY 21C. THE ACFT TOUCHED DOWN LONG ON THE 8500 FT RWY. THE FLT CREW RPRTD THAT 'EVERYTHING SEEMED NORMAL DURING THE ROLLOUT UNTIL BELOW 80 KNOTS WHEN THE AIRCRAFT DID NOT SEEM TO SLOW.'  THE CREWMEMBERS WERE UNABLE TO STOP ON THE REMAINING RWY DESPITE THE USE OF BRAKES & REVERSE THRUST. INFO OBTAINED DURING THE INVESTIGATION SHOWED THAT THE ACFT HAD TOUCHED DOWN WITH AN ESTIMATED 5037 FT OF RWY REMAINING. ACCORDING TO THE PERFORMANCE HANDBOOK, THE STOPPING DISTANCE ON AN ICY RWY WOULD HAVE BEEN OVER 5100 FT.

## FAA reports on this event (1)

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

- [Incident 19860102026139I](https://openairdocs.org/incident/19860102026139I), Jan 2, 1986: Doug DC1010, Detroit, MI. During landing rollout, brakes lost effectiveness. Aircraft stopped 500 feet from end of runway lights.

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.
