The NTSB's narrative final · quoted from the NTSB record

The instructor stated that when they turned base to final they were approximately 250' above ground level (agl). The CFI told the student to use 'Full' spoilers to bring the aircraft back on a normal glide path to the runway. The CFI stated that at approximately 100' agl the student had 'Full' spoilers deployed and had an excessive nose down attitude. The CFI told the student 'Close' the spoilers and bring the nose up to reduce the excessive airspeed. The CFI stated that the student began to bring the nose up, without closing the spoilers, and that he took control of the aircraft at this point. The CFI closed the spoilers completely but the aircraft was already entering a stall. The CFI stated that he reduced the angle of attack in order to regain airspeed and then flared close to the ground. The CFI stated that the aircraft 'Pancaked-in, a landing hard enough to throw me into the shoulder straps and my head down so that briefly I could not see outside.' The aircraft drifted to right side of the runway and the right wing impacted a runway light before coming to a stop.
