Analysis

The plt allowed the airspeed to decrease to the extent of activating the acft stall warning system on final apch at 100 ft above the ground and 200 ft from the end of the rwy. He corrected the low airspeed condition by lowering the nose, resulting in a high rate of descent. He initiated an excessive nose high landing flare to compensate for the high rate of decent, causing the acft to stall 10-15 ft above the rwy. The plt continued the landing with no corrective action. The acft impacted the rwy in a nose low attitude, bounced 50-60 ft into the air, crossed a dirt road and landed in a fld where it collided with a large bale of hay.
