Analysis
The coplt (dual student) was to get a prof check on the 1st leg of the flt with a simulated single eng pwr loss on tkof. According to witnesses, the tkof was normal until lift-off aprx 3200' down the rwy; but after lift-off, the acft clbd only about 50' & didn't seem to accelerate. They rprtd the nose pitched up & the acft went in a steep bank attitude nr the dep end of the rwy. Subsequently, it dscndd & crashed in wooded terrain in a rgt wing down, nose hi attitude. A by- stander tried to get in the acft to rescue the plts, but the door was jammed & he was unable to break the cabin windows.a fire erupted & engulfed the acft. Due to rough terrain, there was a delay in getting fire fighting equipment to the acdnt site. No preimpact mechanical failures were fnd. The gear, flaps & spoilers were fnd in the retracted psn. For tkof, the flaps should have been extd to the 8 or 20 deg position. The stall speeds for 20 deg, 8 deg & no flaps were 104.5, 109.0 & 119.5 KTS, respectively. The capt was an FAA designated flt examiner & a certified flt instructor (CFI).
