Narrative:
During holding at 16000 ft, we got erratic torque and egt indications as well as a surging engine. We followed the aircraft's QRH emergency procedures which required us to retard power on the right engine. We then began a descent due to the lack of power. We were at 15500 ft before we could get a clearance from ZNY on 134.8. He soon gave us a clearance to 12000 ft after we could contact him. We declared an emergency, resolved the problem and landed in mdt without incident. In order to get ATC's attention when the frequency is busy, maybe by activating the identify function on the transponder we can draw his/her attention, thus having ATC ask the appropriate aircraft if something is wrong and if assistance is needed. Supplemental information from acn 378406: if by identing on our transponder we received immediate attention by ATC and could get a clearance for lower, we would've had more time to deal with our situation without declaring an emergency which wasn't one requiring attention from ATC, ie, we could have called our dispatch and maintenance and dealt with and resolved our problem without involving ATC.
Original NASA ASRS Text
Title: A BA32 ACR FLC EXPERIENCES AN ENG LOSS AND THEN STARTS AN INVOLUNTARY DSCNT OUT OF THEIR HOLDING PATTERN. THEY WERE INITIALLY UNABLE TO CONTACT THE CTLR DUE TO FREQ CONGESTION AND THE FLC SEEMED TO BE RELUCTANT TO DECLARE AN EMER OR USE THE XPONDER EMER CODE.
Narrative: DURING HOLDING AT 16000 FT, WE GOT ERRATIC TORQUE AND EGT INDICATIONS AS WELL AS A SURGING ENG. WE FOLLOWED THE ACFT'S QRH EMER PROCS WHICH REQUIRED US TO RETARD PWR ON THE R ENG. WE THEN BEGAN A DSCNT DUE TO THE LACK OF PWR. WE WERE AT 15500 FT BEFORE WE COULD GET A CLRNC FROM ZNY ON 134.8. HE SOON GAVE US A CLRNC TO 12000 FT AFTER WE COULD CONTACT HIM. WE DECLARED AN EMER, RESOLVED THE PROB AND LANDED IN MDT WITHOUT INCIDENT. IN ORDER TO GET ATC'S ATTN WHEN THE FREQ IS BUSY, MAYBE BY ACTIVATING THE IDENT FUNCTION ON THE XPONDER WE CAN DRAW HIS/HER ATTN, THUS HAVING ATC ASK THE APPROPRIATE ACFT IF SOMETHING IS WRONG AND IF ASSISTANCE IS NEEDED. SUPPLEMENTAL INFO FROM ACN 378406: IF BY IDENTING ON OUR XPONDER WE RECEIVED IMMEDIATE ATTN BY ATC AND COULD GET A CLRNC FOR LOWER, WE WOULD'VE HAD MORE TIME TO DEAL WITH OUR SIT WITHOUT DECLARING AN EMER WHICH WASN'T ONE REQUIRING ATTN FROM ATC, IE, WE COULD HAVE CALLED OUR DISPATCH AND MAINT AND DEALT WITH AND RESOLVED OUR PROB WITHOUT INVOLVING ATC.
