Narrative:
Hummer 1 MOA in use by an MTR X. MTR X requested clearance back to mhr and was cleared to a fix to expect the hi ILS. Pilot indicated he did not wish to proceed to that fix, and instead wanted to go to a fix ten miles away. The pilot was told to stand by. Since he refused the previous clearance, I thought it was implicit that he would stay in the MOA. Instead, he exited and separation was lost with an MTR Y aircraft. I feel the problem was caused by both miscom and by slow turns by both aircraft involved. Callback conversation with reporter revealed the following information: callback verified the length of service on instrument reporter. MTR X left the hummer MOA without a clearance and was considered a spillout. Incident was classified as pilot deviation on MTR X. Reporter had let incident progress as far as possible to facilitate the OJT of deviation reporter, but when coordination was late and trnee did not reach fast enough, instrument reporter stepped in. Would not have been a separation problem had the MTR X stayed in the MOA.
Original NASA ASRS Text
Title: MTR SPILLED OUT OF MOA AFTER RECOVERY CLRNC WAS REFUSED AND CREATED A LESS THAN STANDARD SEPARATION SITUATION WITH ANOTHER MTR ENROUTE TO THE MOA.
Narrative: HUMMER 1 MOA IN USE BY AN MTR X. MTR X REQUESTED CLRNC BACK TO MHR AND WAS CLRED TO A FIX TO EXPECT THE HI ILS. PLT INDICATED HE DID NOT WISH TO PROCEED TO THAT FIX, AND INSTEAD WANTED TO GO TO A FIX TEN MILES AWAY. THE PLT WAS TOLD TO STAND BY. SINCE HE REFUSED THE PREVIOUS CLRNC, I THOUGHT IT WAS IMPLICIT THAT HE WOULD STAY IN THE MOA. INSTEAD, HE EXITED AND SEPARATION WAS LOST WITH AN MTR Y ACFT. I FEEL THE PROBLEM WAS CAUSED BY BOTH MISCOM AND BY SLOW TURNS BY BOTH ACFT INVOLVED. CALLBACK CONVERSATION WITH REPORTER REVEALED THE FOLLOWING INFORMATION: CALLBACK VERIFIED THE LENGTH OF SERVICE ON INSTR RPTR. MTR X LEFT THE HUMMER MOA WITHOUT A CLRNC AND WAS CONSIDERED A SPILLOUT. INCIDENT WAS CLASSIFIED AS PLT DEVIATION ON MTR X. RPTR HAD LET INCIDENT PROGRESS AS FAR AS POSSIBLE TO FACILITATE THE OJT OF DEV RPTR, BUT WHEN COORD WAS LATE AND TRNEE DID NOT REACH FAST ENOUGH, INSTR RPTR STEPPED IN. WOULD NOT HAVE BEEN A SEPARATION PROBLEM HAD THE MTR X STAYED IN THE MOA.
