I've had BK tower tell me to check gear after a gear problem on my first command hr in a twin
Put the leaver down expecting 3 green on downwind as per usual but got nothing. There was no one else in the circuit so i stretched the circuit a little for a bit more room and tried the leaver again on base and final, but no luck

. Just as i was about to call a go-around and tell them what was going on, the twr got back to me with the "check gear" or words to that effect.
Got her down with 3 green in the end though
