Narrative:

While preparing for takeoff on runway 18, gtu, I observed a cessna on base leg for the same runway. I announced on CTAF that I was '...rolling for departure on runway 18.' after passing the hold line, but before entering the runway, I observed the cessna turning final. The cessna announced 'aircraft taking off on runway 18, do you see me on short final?' I announced 'I have you in sight, I will hold.' I stopped short of the runway, but past the hold line. The cessna continued his approach, but over the fence line, he announced 'going around due to runway incursion.' he then proceeded to go around. I launched shortly thereafter and continued without incident. 1) the pattern was very crowded, frequency congested, I felt pressure (self-induced) to hurry my departure and get out of the 'furball.' 2) I observed the departure of an aircraft just prior to mine, with an aircraft on base to final turn, without incident. I assumed that was an efficient procedure to work a crowded pattern. On reflection, my experience level is inadequate to make that a valid assumption. 3) corrective action -- ensure that pattern is clear. Wait as necessary to ensure that final approach cannot be entered prior to crossing hold line.

Title: A PA28 PLT, TAXIING FOR TKOF AT GTU, TAXIED PAST THE HOLD SHORT LINE, CAUSING ACFT ON FINAL TO MAKE A GAR.

Narrative: WHILE PREPARING FOR TKOF ON RWY 18, GTU, I OBSERVED A CESSNA ON BASE LEG FOR THE SAME RWY. I ANNOUNCED ON CTAF THAT I WAS '...ROLLING FOR DEP ON RWY 18.' AFTER PASSING THE HOLD LINE, BUT BEFORE ENTERING THE RWY, I OBSERVED THE CESSNA TURNING FINAL. THE CESSNA ANNOUNCED 'ACFT TAKING OFF ON RWY 18, DO YOU SEE ME ON SHORT FINAL?' I ANNOUNCED 'I HAVE YOU IN SIGHT, I WILL HOLD.' I STOPPED SHORT OF THE RWY, BUT PAST THE HOLD LINE. THE CESSNA CONTINUED HIS APCH, BUT OVER THE FENCE LINE, HE ANNOUNCED 'GOING AROUND DUE TO RWY INCURSION.' HE THEN PROCEEDED TO GO AROUND. I LAUNCHED SHORTLY THEREAFTER AND CONTINUED WITHOUT INCIDENT. 1) THE PATTERN WAS VERY CROWDED, FREQ CONGESTED, I FELT PRESSURE (SELF-INDUCED) TO HURRY MY DEP AND GET OUT OF THE 'FURBALL.' 2) I OBSERVED THE DEP OF AN ACFT JUST PRIOR TO MINE, WITH AN ACFT ON BASE TO FINAL TURN, WITHOUT INCIDENT. I ASSUMED THAT WAS AN EFFICIENT PROC TO WORK A CROWDED PATTERN. ON REFLECTION, MY EXPERIENCE LEVEL IS INADEQUATE TO MAKE THAT A VALID ASSUMPTION. 3) CORRECTIVE ACTION -- ENSURE THAT PATTERN IS CLR. WAIT AS NECESSARY TO ENSURE THAT FINAL APCH CANNOT BE ENTERED PRIOR TO XING HOLD LINE.
