<< >> NASA ASRS Report 331821, March 1996

Upon checking in with approach control, the flight was instructed to slow to 210 KTS, turn left at the 10 DME fix to 085 degree heading for downwind. The flight proceeded on in not knowing the microphone was stuck. Approaching the 10 DME fix thinking it was quiet and not cleared down to 6000 ft the reporter checked in with approach and learned the microphone was stuck. The flight was brought into the pattern and landed without further problem. The microphone was written up.

Narrative:

After checking in with approach control they instructed us to slow to 210 KTS, and turn left at 10 DME fix to 085 degree heading for downwind. We proceeded in toward iah with a stuck microphone. Approaching the 10 DME fix thinking it was quiet and not yet cleared down to 6000 ft. We checked with approach control to find out we had a hot microphone. We turned north. They cleared us down into the pattern for an uneventful landing with no known conflict. We put the write-up in the book and went on.
