Kolb TWINSTAR accident near Reynolds, Georgia, March 15, 2015

On March 15, 2015 at about 10:15 pm local time, a 2007 Kolb TWINSTAR, registered N193Y, was substantially damaged in an accident during maneuvering (low-alt flying) near Reynolds, Georgia. It was a personal flight under general aviation rules (Part 91). 1 person was killed. The weather was visual conditions (good weather).

The NTSB's probable cause their words, unchanged

The student pilot’s failure to maintain adequate airspeed while maneuvering, which resulted in the airplane exceeding its critical angle-of-attack and experiencing an aerodynamic stall. Contributing to the accident was the student pilot's decision to operate the airplane at a low altitude that did not allow for stall recovery.

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

The student pilot was flying at a low altitude over a relative's residence. The airplane circled over the house twice before overflying a wooded area at the neighboring residence and, according to a witness, appeared to "hover" as it flew over the trees. Shortly thereafter, the airplane suddenly pitched nose-down and impacted terrain. Witness observations were consistent with the airplane flying at a very low groundspeed, and likely a very low airspeed. The nose-down impact angle, and absence of ground scars or debris path were consistent with a stall at the time of impact. Because the airplane was operating at low altitude, the airplane's altitude was insufficient to allow the student pilot to recover the airplane from the stall. Although oil was found on the engine case and empennage, no pre-impact mechanical malfunctions or failures were found with the engine or airplane that would have precluded normal operation.
