An Air France Boeing 777-300, registration F-GZNC performing flight AF-179 from Mexico City (Mexico) to Paris Charles de Gaulle (France), was taxiing for departure from Mexico City, when the aircraft entered runway 05L via taxiway B6 for crossing about 800 meters/2600 feet past the displaced runway threshold without clearance at 21:10L (Apr 13th 02:10Z).

At that time an Aeromexico Connect Embraer ERJ-190, registration XA-FAC performing flight AM-2538 from Mexico City to San Luis Potosi (Mexico), was accelerating for takeoff from runway 05L and rejected takeoff at low speed (about 50 knots over ground) as result of the runway incursion. The aircraft vacated the runway via taxiway B4 about 150 meters/500 feet past the displaced runway threshold. The aircraft returned to the apron.

The Air France Boeing departed runway 05R about 48 minutes after the runway incursion.

Maxico's AIB rated the occurrence an incident and opened an investigation.

The AIB in their initial notification however misidentified runway 05R as the runway where the incursion occurred and XA-MAC as the aircraft that rejected takeoff. Mode-S data indicate XA-MAC departed runway 05L at 02:48Z, did not reject takeoff and began taxi after F-GZNC had crossed both runways 05L and 05R. Mode-S data also show that XA-FAC rejected takeoff from runway 05L at 02:10Z exactly at the time when F-GZNC crossed runway 05L. Mode-S data further reveal that the Air France Boeing stopped between the two runways for almost 20 minutes before crossing runway 05R still at taxiway B6 at 02:30Z, then turned right towards the threshold of runway 05R and departed at 02:58Z.
