Narrative:

We were being switched to high altitude ATC and a stuck microphone on the previous frequency prevented ATC from changing the course of another aircraft on a collision course with us. When we checked in on the new frequency, the controller yelled at us to climb immediately to FL260. We were at 350 KIAS and pitched up to above 15 degrees, vsi above 5000 FPM, and avoided the other aircraft. We do not have TCASII. So far, the military has deemed not to put it on these 40 yr old airplanes. As a crew member, I think the military needs to do it, regardless of aircraft age, for any passenger carrying airplanes. I have filed a hatr also. This was not ATC's fault, nor ours, but a system fault due to a frequency change and a stuck microphone.

Original NASA ASRS Text

Title: MIL X HAD NMAC LTSS FROM ACFT Y DUE TO STUCK MIKE.

Narrative: WE WERE BEING SWITCHED TO HIGH ALT ATC AND A STUCK MIKE ON THE PREVIOUS FREQ PREVENTED ATC FROM CHANGING THE COURSE OF ANOTHER ACFT ON A COLLISION COURSE WITH US. WHEN WE CHKED IN ON THE NEW FREQ, THE CTLR YELLED AT US TO CLB IMMEDIATELY TO FL260. WE WERE AT 350 KIAS AND PITCHED UP TO ABOVE 15 DEGS, VSI ABOVE 5000 FPM, AND AVOIDED THE OTHER ACFT. WE DO NOT HAVE TCASII. SO FAR, THE MIL HAS DEEMED NOT TO PUT IT ON THESE 40 YR OLD AIRPLANES. AS A CREW MEMBER, I THINK THE MIL NEEDS TO DO IT, REGARDLESS OF ACFT AGE, FOR ANY PAX CARRYING AIRPLANES. I HAVE FILED A HATR ALSO. THIS WAS NOT ATC'S FAULT, NOR OURS, BUT A SYS FAULT DUE TO A FREQ CHANGE AND A STUCK MIKE.
