Narrative:

We were returning from hop to blv. Refueling, WX check, and refile at FSS at pah. I was on the controls, started the engine and brought aircraft to operating RPM. PIC called aircraft and they said 'something north departure', I made a fast takeoff to the north. After crossing the active (runway 22), tower said, 'you were not cleared for takeoff', when questioned, he said he had said 'set up for north takeoff'. Apparently I flew in front of another aircraft, which may have had to take evasive maneuver. Contributing factors, bad WX caused me to rush, didn't want to arrive at blv west/O plenty of fuel, made me assume that only helicopters would be operating (airfield was VFR, but trws throughout area would have kept me from flying a fixed wing aircraft west/O airborne radar). We were rushing to get home the pics daughter had birthday party, his wife was mad at him for not being there. PIC was company commander and had ground duties to attend to. Wanted to get to destination while daylight allowed picking our way through trws. I think 'set up for north departure' is not standard phraseology? I am not familiar, would rather have used 'plan for north departure after arriving aircraft', the airfield was deserted and the extra words wouldn't have tied up the channel (both pilots thought we heard 'mlt X cleared for north departure'). I'm very hard of hearing and the army's radios are junk. I'm operating on a waiver for hearing. With the volume all the way up on the ics box I can just barely hear, if I blast the radio volume I can hear, but then I blow out the other pilot. I hear real good west/O my earplugs in under my helmet, but I have to be very careful about hearing conservation, so I'm constantly trying to balance the placement of my earplugs between in so far I can't hear and out so loose that it damages my hearing. Corrective measures, if the radios were better, I've looked for a line amp, but can't find one. Standard phraseology, of course, readbacks and crew xchks, but human nature being what it is...

Title: MIL COPTER MISUNDERSTOOD CTLRS INSTRUCTIONS AND INSTEAD OF HOLDING ON THE GND DEPARTED CAUSING A MISSED APCH TO LNDG TRAFFIC.

Narrative: WE WERE RETURNING FROM HOP TO BLV. REFUELING, WX CHK, AND REFILE AT FSS AT PAH. I WAS ON THE CTLS, STARTED THE ENG AND BROUGHT ACFT TO OPERATING RPM. PIC CALLED ACFT AND THEY SAID 'SOMETHING N DEP', I MADE A FAST TKOF TO THE N. AFTER XING THE ACTIVE (RWY 22), TWR SAID, 'YOU WERE NOT CLRED FOR TKOF', WHEN QUESTIONED, HE SAID HE HAD SAID 'SET UP FOR N TKOF'. APPARENTLY I FLEW IN FRONT OF ANOTHER ACFT, WHICH MAY HAVE HAD TO TAKE EVASIVE MANEUVER. CONTRIBUTING FACTORS, BAD WX CAUSED ME TO RUSH, DIDN'T WANT TO ARRIVE AT BLV W/O PLENTY OF FUEL, MADE ME ASSUME THAT ONLY HELIS WOULD BE OPERATING (AIRFIELD WAS VFR, BUT TRWS THROUGHOUT AREA WOULD HAVE KEPT ME FROM FLYING A FIXED WING ACFT W/O AIRBORNE RADAR). WE WERE RUSHING TO GET HOME THE PICS DAUGHTER HAD BIRTHDAY PARTY, HIS WIFE WAS MAD AT HIM FOR NOT BEING THERE. PIC WAS COMPANY COMMANDER AND HAD GND DUTIES TO ATTEND TO. WANTED TO GET TO DEST WHILE DAYLIGHT ALLOWED PICKING OUR WAY THROUGH TRWS. I THINK 'SET UP FOR N DEP' IS NOT STANDARD PHRASEOLOGY? I AM NOT FAMILIAR, WOULD RATHER HAVE USED 'PLAN FOR N DEP AFTER ARRIVING ACFT', THE AIRFIELD WAS DESERTED AND THE EXTRA WORDS WOULDN'T HAVE TIED UP THE CHANNEL (BOTH PLTS THOUGHT WE HEARD 'MLT X CLRED FOR N DEP'). I'M VERY HARD OF HEARING AND THE ARMY'S RADIOS ARE JUNK. I'M OPERATING ON A WAIVER FOR HEARING. WITH THE VOLUME ALL THE WAY UP ON THE ICS BOX I CAN JUST BARELY HEAR, IF I BLAST THE RADIO VOLUME I CAN HEAR, BUT THEN I BLOW OUT THE OTHER PLT. I HEAR REAL GOOD W/O MY EARPLUGS IN UNDER MY HELMET, BUT I HAVE TO BE VERY CAREFUL ABOUT HEARING CONSERVATION, SO I'M CONSTANTLY TRYING TO BALANCE THE PLACEMENT OF MY EARPLUGS BTWN IN SO FAR I CAN'T HEAR AND OUT SO LOOSE THAT IT DAMAGES MY HEARING. CORRECTIVE MEASURES, IF THE RADIOS WERE BETTER, I'VE LOOKED FOR A LINE AMP, BUT CAN'T FIND ONE. STANDARD PHRASEOLOGY, OF COURSE, READBACKS AND CREW XCHKS, BUT HUMAN NATURE BEING WHAT IT IS...
