A B727 DEPARTED AND LANDED WITH THE WHEEL CHOCKS STUCK BTWN THE R MAIN GEAR.

Narrative

DURING A SHORT FIELD TKOF AT ZZZ AT AROUND 100 KTS; THE TWR CTLR MUMBLED SOMETHING ABOUT ABORT AND MISSING CHOCKS. NOBODY OF THE 4 CREW MEMBERS IN THE COCKPIT HEARD HIM CLRLY. NOBODY UNDERSTOOD NOR ACKNOWLEDGED THIS XMISSION! WE CONTINUED THE TKOF ROLL AND CLBED OUT NORMALLY. THE TWR CTLR QUICKLY; SAID 'ACR X; CONTACT DEP' AFTER TKOF. WHICH WE DID. ALL OUR COCKPIT INDICATIONS WERE NORMAL; TKOF WAS NORMAL AND ACFT HANDLING WAS NORMAL. THE CTLR NEVER REPEATED THAT XMISSION OR MADE SURE WE ACKNOWLEDGED THAT XMISSION; JUST 'ACR X; CONTACT DEP.' THE WHOLE CREW DISCUSSED THIS DURING CLB; AND THOUGHT IT WAS PROBABLY A MISTAKE OR FOR ANOTHER ACFT; ESPECIALLY SINCE HE NEVER REPEATED THIS AND HANDED US OFF NORMALLY TO DEP CTL. THE GND HANDLER GAVE US THE 'CHOCKS AWAY' SIGNAL BEFORE TAXI AND THE ACFT TAXIED NORMALLY. ALSO; DEP CTL DID NOT RELAY ANY IRREGULARITIES TO US. THE FE THEN CALLED IN THE TIMES TO THE GND HANDLER AND NO IRREGULARITIES WERE RELAYED TO US. AFTER THE CREW DISCUSSION; WITH NO IRREGULARITIES NOTED OR RELAYED AND NORMAL FLT; EVERYBODY THOUGHT IT WAS A MISTAKE OR FOR ANOTHER ACFT. THIS WAS A VERY SHORT FLT; ONLY 160 MI. WE THEN STARTED PLANNING FOR THE DSCNT AND LNDG INTO ZZZ1. WE MADE A NORMAL LNDG; TAXI-IN AND SHUTDOWN. DURING POSTFLT WALKAROUND; MECH DISCOVERED CHOCKS HANGING BTWN R MAIN WHEELS. SUGGESTIONS: 1) IF GND HANDLER KNEW OF AN IRREGULARITY; MAKE SURE THE ACFT CREW RECEIVES THE MESSAGE AND ACKNOWLEDGES THE IRREGULARITIES. COMMUNICATE! 2) AT SMALL ARPT OUTSTATIONS; HAVE MECH DO LAST MIN WALKAROUND TO DOUBLECHK GND HANDLER'S REMOVAL OF THE CHOCKS. 3) TWR CTLR SHOULD NOT MUMBLE POSSIBLE ABORT TO ACFT TAKING OFF. ESPECIALLY FOR LARGE HVY ACFT DEPARTING ON A SHORT RWY. THIS IS VERY DANGEROUS! 4) IF TWR WAS AWARE OF AN IRREGULARITY; MAKE SURE ACFT CREW RECEIVES AND ACKNOWLEDGES THE IRREGULARITY! COMMUNICATE! 5) GND HANDLER SHOULD TRAIN TO PROFICIENCY TO MAKE SURE THIS DOES NOT HAPPEN AGAIN!
