One factor may have been that the pilot was accustomed to flying a twin, and the approach speeds in the Sierra may have seemed particularly slow. In polite aviation circles, it's considered bad form to put the nosewheel. It happens most frequently when the pilot is anxious to get the aircraft on the ground in a hurry, such as a short runway. if you find that the airplane is not settling and you're tempted to lower the nose, that's an excellent tip-off that the landing isn't worth salvaging. When we don't routinely operate off a short strip, it takes regular practice or the short-field skills will atrophy quickly. This pilot may have waited too long before starting the go-around, assuming no damage to the aircraft.
Timing is everything.
If you passed up the chance to go around earlier, take your lumps at the airport boundary, on the ground, at 30 knots. This is far safer than wishing for airspeed and altitude that you don't have 50 to 100 feet up. The investigators could not determine for sure if the prop was damaged in the bounces, but there is some strong suspicion. The prop was curled in a manner suggesting a prop strike. It was not possible to link the several prop-strike marks on the runway to this accident.
