Analysis

One of the purposes of the flt was for the plt to experience a takeoff at max gross wt. He put a 150 lb bag of cement in the right front seat to simulate the wt of a passenger, then initiated a takeoff from a sod rwy that was soft after a recent thaw, using 15 deg of flaps. The plt said that he lifted off prematurely & the acft settled back to the rwy & was slowed by the soft field conditions. Also, he said he waited too long to abort & the acft went off the end of the rwy & thru a fence.
