On January 29, 1996, a Bell 47G-2A1 (registration N6569H) was involved in an aviation accident near Honiara, PO, BP. Investigators recorded the probable cause as: the pilot and the ship crew's failure to assure the tie down strap was removed prior to liftoff. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
During a shipboard takeoff, a helicopter's right rear skid remained tethered by a tie-down rope, causing a roll and inverted water impact. The pilot and aircraft were not recovered due to water depth, with no mechanical issues reported.
Overview
A helicopter operating from a ship experienced an accident during takeoff when a tie-down rope remained attached to the right rear skid. The aircraft rolled to the right and struck the water inverted, sinking immediately. The flotation devices on the skids separated during the impact. Due to the depth of the water, the pilot and the aircraft were not recovered.
Sequence of Events
The pilot lifted off from the ship with the right rear skid still secured by a tie-down rope. As the helicopter ascended, the rope induced a rolling motion. The aircraft banked right and descended into the water, impacting in an inverted position. It submerged promptly. The floatation devices detached from the skids upon impact.
Investigation Findings
The operator reported that no mechanical problems existed with the helicopter prior to the accident. No further details regarding the cause were provided. The water depth at the accident site prevented recovery of the pilot and the aircraft.
