## Probable cause

The dynamic rollover encountered by the pilot.  Factors were the inadequate remedial action by the pilot due to his failure to prevent the rollover, and the inadequate facility with regard to the design of the landing platform.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of control - on ground/water, landing
  - dynamic rollover - encountered, pilot in command (cause)
  - facility inadequate (contributing factor)
  - remedial action - inadequate, pilot in command (contributing factor)
- Roll over, landing

## Analysis

The helicopter was substantially damaged when it rolled off of a landing platform.  The pilot reported that he had landed on the landing platform, but the helicopter was not centered.  He stated that he attempted to re-position the helicopter on the platform and that during the re-positioning procedure the right skid shoe "may have become wedged against the raised wooden surface resulting in a suspected dynamic rollover situation."  In his written report, the pilot suggested modifications to the mobile landing platform to eliminate the gaps between the wooden planks.  The pilot reported no mechanical deficiencies with regard to the helicopter.

## Factual narrative
