A PA31 cpr pilot attempted to hold the brakes while waiting for the condensation on the windows to clear as the engines warmed up. The aircraft crept forward and the left wing struck the right wing of an HS25 causing minor damage to both aircraft.

Narrative:
After boarding and serving 5 passenger, I started both engines and got my IFR clearance. As the result of high humidity (moderate rain) and the 6 people on board, all the rainstorms on the aircraft fogged up. I turned on the heater and defroster. I proceeded with my checklist while waiting for the windshield to clear. I then felt a light jerk. Looking out, I saw that my left wing was touching the right wing of a cpr jet. My first thought was that the other aircraft had hit me as I was standing still. The right seat passenger then informed me that my aircraft had been creeping forward and came in contact with the other aircraft. My feet were on the brake, but I must have relaxed the pressure without realizing it allowing my aircraft to move forward. Because of the foggy windows, the rain and the darkness, I didn't have any visual clues that I was moving. My aircraft had moved about 50 ft before contacting the other aircraft (#2). The damage to my aircraft was minimal: a small tear in the deicing boot and a 4 inch scratch on top of the leading edge. Preliminary inspection of the only aircraft (#2) shows the only damage to be a torn-off static wick on the right aileron. This incident was caused by my failure to properly set the hand brake prior to starting the engines. Contributing factors were rain, darkness, condensation and fog inside the aircraft and to a small extent tiredness. At the time of the incident I had been up for over 15 hours and on duty for 8 hours. I learned a valuable lesson: I will never ever start an aircraft engine until I assure that the hand brake is set properly and leave it set until ready to taxi out.

Title: A PA31 CPR PLT ATTEMPTED TO HOLD THE BRAKES WHILE WAITING FOR THE CONDENSATION ON THE WINDOWS TO CLR AS THE ENGS WARMED UP. THE ACFT CREPT FORWARD AND THE L WING STRUCK THE R WING OF AN HS25 CAUSING MINOR DAMAGE TO BOTH ACFT.
Narrative: AFTER BOARDING AND SERVING 5 PAX, I STARTED BOTH ENGS AND GOT MY IFR CLRNC. AS THE RESULT OF HIGH HUMIDITY (MODERATE RAIN) AND THE 6 PEOPLE ON BOARD, ALL THE RAINSTORMS ON THE ACFT FOGGED UP. I TURNED ON THE HEATER AND DEFROSTER. I PROCEEDED WITH MY CHKLIST WHILE WAITING FOR THE WINDSHIELD TO CLR. I THEN FELT A LIGHT JERK. LOOKING OUT, I SAW THAT MY L WING WAS TOUCHING THE R WING OF A CPR JET. MY FIRST THOUGHT WAS THAT THE OTHER ACFT HAD HIT ME AS I WAS STANDING STILL. THE R SEAT PAX THEN INFORMED ME THAT MY ACFT HAD BEEN CREEPING FORWARD AND CAME IN CONTACT WITH THE OTHER ACFT. MY FEET WERE ON THE BRAKE, BUT I MUST HAVE RELAXED THE PRESSURE WITHOUT REALIZING IT ALLOWING MY ACFT TO MOVE FORWARD. BECAUSE OF THE FOGGY WINDOWS, THE RAIN AND THE DARKNESS, I DIDN'T HAVE ANY VISUAL CLUES THAT I WAS MOVING. MY ACFT HAD MOVED ABOUT 50 FT BEFORE CONTACTING THE OTHER ACFT (#2). THE DAMAGE TO MY ACFT WAS MINIMAL: A SMALL TEAR IN THE DEICING BOOT AND A 4 INCH SCRATCH ON TOP OF THE LEADING EDGE. PRELIMINARY INSPECTION OF THE ONLY ACFT (#2) SHOWS THE ONLY DAMAGE TO BE A TORN-OFF STATIC WICK ON THE R AILERON. THIS INCIDENT WAS CAUSED BY MY FAILURE TO PROPERLY SET THE HAND BRAKE PRIOR TO STARTING THE ENGS. CONTRIBUTING FACTORS WERE RAIN, DARKNESS, CONDENSATION AND FOG INSIDE THE ACFT AND TO A SMALL EXTENT TIREDNESS. AT THE TIME OF THE INCIDENT I HAD BEEN UP FOR OVER 15 HRS AND ON DUTY FOR 8 HRS. I LEARNED A VALUABLE LESSON: I WILL NEVER EVER START AN ACFT ENG UNTIL I ASSURE THAT THE HAND BRAKE IS SET PROPERLY AND LEAVE IT SET UNTIL READY TO TAXI OUT.
