NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The acft rolled over in a high x-wind after landing while deplaning passengers. The acft had landed on a moving barge. A landing into the wind was blocked by a crane so the plt sideslipped from a flt path that paralleled the ships movement. The wind was across the barge from left to right. After landing the plt did not change the x-wind heading of the acft. According to a witness the acft was heading toward the rt side of the vessel & the wind was from the left. The plt left the engs at 'fly' because he was unsure of the stability of the position but he allowed the passengers to deplane. As the passengers deplaned witnesses said the acft's left landing gear lifted slightly off the deck. This reportedly happened 2 or 3 times before the acft rolled over. The plt stated that as the roll began he applied full left cyclic with no effect. One witness said that there was a strong gust of wind at the time of the roll-over.
