Synopsis
ZFW Controller described a terrain separation event when an IFR aircraft transferred from D10 failed to comply with instructions and D10 would not respond to inter phone calls.
Narrative
Aircraft X was handed off to me from Approach at 30 going to SWI with approaches at GYI and DUA in remarks. The aircraft was on a heading from D10 as per the LOA; I took the hand off and immediately called Approach to get control because the heading the aircraft was on had him pointed toward an antenna tower where the MEA was 37 hundred feet. D10 did not answerer the line after three calls; I then attempted to turn the aircraft 30 right with no response. I attempted a second time and received a correct read back however; the aircraft did not comply. I then turned the aircraft to a 030 heading with no response. Then I once again relayed the instruction and then received a correct read back and once again the aircraft did not comply. Now the situation was imminent; and in my airspace so I turned the plane and climbed him to 40 immediately with no response twice! The third time I issued the clearance the aircraft read it back correctly but did not comply. My instructor the keyed up to relay the same instructions I gave to the pilot. It was then that the pilot complied. Not a contributing factor however; there was weather in the sector. If the pilot had been listening and complying with clearances; this situation would have never taken place.
Second reporter narrative
I was training on the FRI Lo sector. Aircraft X was a northbound departure from DFW Approach at 030. The minimum IFR altitude is 037 right at the approach boundary due to an antenna. The Trainee called the Approach sector 3 times to get control to climb the aircraft but approach never answered the line. The trainee then issued a turn to the aircraft that would have provided separation from the antenna. The pilot failed to make the turn as instructed and violated the protected airspace. All IFR departures northbound from DFW should be 040 or above or on a vector to miss the antennas.
