Teb tower observes situation between local controller and ground controller, controller training in progress. Local controller approves crossing 1 of 2 runways and ground controller trainee clears C172 but misses incorrect readback and C172 crosses both runways. Local controller initiates takeoff DA50 abort due to crossing C172. Tower controller alleges incident went unrpted because trainee was supervisor.

Narrative:

Cessna requesting taxi back to ramp needed to cross 2 runways. Ground control (training in progress) requested runway xings of both runways. Local control approved crossing runway 19 to hold short of runway 24. Ground trainee issued crossing runway 19 hold short of runway 24. Pilot read back cross runway 19, cross runway 24. Trainee and trainer both missed the incorrect readback. Tower cleared DA50 for takeoff on runway 24. Tower observed cessna crossing runway 19 and crossing hold line for runway 24 and canceled takeoff clearance for the DA50 who had already begun his takeoff roll. This incident went unrpted as ground trainee is new supervisor at facility. Both trainee and trainer remained on position.

Title: TEB TWR OBSERVES SIT BTWN LCL CTLR AND GND CTLR, CTLR TRAINING IN PROGRESS. LCL CTLR APPROVES XING 1 OF 2 RWYS AND GND CTLR TRAINEE CLRS C172 BUT MISSES INCORRECT READBACK AND C172 CROSSES BOTH RWYS. LCL CTLR INITIATES TKOF DA50 ABORT DUE TO XING C172. TWR CTLR ALLEGES INCIDENT WENT UNRPTED BECAUSE TRAINEE WAS SUPVR.

Narrative: CESSNA REQUESTING TAXI BACK TO RAMP NEEDED TO CROSS 2 RWYS. GND CTL (TRAINING IN PROGRESS) REQUESTED RWY XINGS OF BOTH RWYS. LCL CTL APPROVED XING RWY 19 TO HOLD SHORT OF RWY 24. GND TRAINEE ISSUED XING RWY 19 HOLD SHORT OF RWY 24. PLT READ BACK CROSS RWY 19, CROSS RWY 24. TRAINEE AND TRAINER BOTH MISSED THE INCORRECT READBACK. TWR CLRED DA50 FOR TKOF ON RWY 24. TWR OBSERVED CESSNA XING RWY 19 AND XING HOLD LINE FOR RWY 24 AND CANCELED TKOF CLRNC FOR THE DA50 WHO HAD ALREADY BEGUN HIS TKOF ROLL. THIS INCIDENT WENT UNRPTED AS GND TRAINEE IS NEW SUPVR AT FACILITY. BOTH TRAINEE AND TRAINER REMAINED ON POS.
