Piper PA-18-150
Prelim report (2 minor injuries)

During a FAA Part 135.293(b) flight check in a Piper PA-18-150, the airplane received substantial damage on 02-16-2011 during the second attempted landing. The ATP rated pilot was completing the yearly Part 135 ride with an FAA inspector and had completed all upper air work. A go around was made on the first attempt due to high winds and the pilot's concern of losing aircraft control when he lowered the tail wheel. On the second attempt to runway 25, the winds were reported at 180 degrees and 18 knots gusting to 25 knots and the pilot had landed and was moving slowly when a gust of wind lifted the aircraft 3 to 5 feet in the air. The airplane then dropped to the ground and the wind lifted the tail resulting in the airplane nosing over.

Prelim report (2 minor injuries)

After a maximum performance takeoff on a training flight, a Eurocopter AS350-B2 helicopter received substantial damage on 02-23-2011, at RIV (March Air Reserve Base (RIV), Riverside, CA). The CFI pilot informed the other pilot that he would simulate a hydraulic failure after takeoff, which he did at approximately 20 feet AGL by activating the hydraulic test switch. After activating the switch the helicopter moved backwards and began an un-commanded counterclockwise rotation. The helicopter impacted the taxiway and landed hard.
