Narrative:

Assigned 6000 ft -- unable to get a clear and readable response from center for our request for lower altitude due to moderate to severe turbulence. I saw an opening above us and initiated a climb to 10000 ft. My first officer tried 4 times to get lower and he called 5 times telling center we were in a climb due to severe turbulence. We were IMC with nothing on the radar but the clouds were becoming very black. Center told us that they had no problem with our altitude change and that they could hear us ok but that we were unable to hear them. While in the climb I also had my first officer press his identify button to get the controller's attention. Also noteworthy, the surface winds at mqt were 290 degrees - 360 degrees 18 gusting to 38 and at present time I had 70 hours as PIC in this aircraft. Supplemental information from acn 241769: it was either climb or lose a wing! Severe turbulence. Msp transmitter in mqt area stinks.

Original NASA ASRS Text

Title: SMT CLBS ABOVE ASSIGNED ALT TO ESCAPE SEVERE TURB.

Narrative: ASSIGNED 6000 FT -- UNABLE TO GET A CLR AND READABLE RESPONSE FROM CTR FOR OUR REQUEST FOR LOWER ALT DUE TO MODERATE TO SEVERE TURB. I SAW AN OPENING ABOVE US AND INITIATED A CLB TO 10000 FT. MY FO TRIED 4 TIMES TO GET LOWER AND HE CALLED 5 TIMES TELLING CTR WE WERE IN A CLB DUE TO SEVERE TURB. WE WERE IMC WITH NOTHING ON THE RADAR BUT THE CLOUDS WERE BECOMING VERY BLACK. CTR TOLD US THAT THEY HAD NO PROB WITH OUR ALT CHANGE AND THAT THEY COULD HEAR US OK BUT THAT WE WERE UNABLE TO HEAR THEM. WHILE IN THE CLB I ALSO HAD MY FO PRESS HIS IDENT BUTTON TO GET THE CTLR'S ATTN. ALSO NOTEWORTHY, THE SURFACE WINDS AT MQT WERE 290 DEGS - 360 DEGS 18 GUSTING TO 38 AND AT PRESENT TIME I HAD 70 HRS AS PIC IN THIS ACFT. SUPPLEMENTAL INFO FROM ACN 241769: IT WAS EITHER CLB OR LOSE A WING! SEVERE TURB. MSP XMITTER IN MQT AREA STINKS.
