Narrative:

Rejected takeoff because aircraft felt out of trim, and while trimming during takeoff roll, trimmed out of green takeoff band, and triggered the aircraft warning horn. Rejected takeoff, at 80 KTS. Taxied back to end of runway, double-checked weight and balance calculations, found ok, and made successful takeoff. What caused problem: initial weight and balance, indicated that the aircraft was loaded tail heavy. (Not out of limits). Because of this, I was cognizant of possible out of trim situation. I am inexperienced in the aircraft, and I thought aircraft felt like it wanted to rotate, too early. I was overly cautious due to my experience level.

Title: AN ACR REJECTED A TKOF, SUSPECTING AN OUT-OF-TRIM CONDITION.

Narrative: REJECTED TKOF BECAUSE ACFT FELT OUT OF TRIM, AND WHILE TRIMMING DURING TKOF ROLL, TRIMMED OUT OF GREEN TKOF BAND, AND TRIGGERED THE ACFT WARNING HORN. REJECTED TKOF, AT 80 KTS. TAXIED BACK TO END OF RWY, DOUBLE-CHKED WT AND BAL CALCULATIONS, FOUND OK, AND MADE SUCCESSFUL TKOF. WHAT CAUSED PROB: INITIAL WT AND BAL, INDICATED THAT THE ACFT WAS LOADED TAIL HVY. (NOT OUT OF LIMITS). BECAUSE OF THIS, I WAS COGNIZANT OF POSSIBLE OUT OF TRIM SIT. I AM INEXPERIENCED IN THE ACFT, AND I THOUGHT ACFT FELT LIKE IT WANTED TO ROTATE, TOO EARLY.
