EASA SIB 2016-18R1: Dynamic Rollout during Hoisting and/or External Sling Load Operations

What to do

Operators conducting hoist or external sling load operations should review and implement the recommended safety measures outlined in CASA AWB 25-030, 25-033, and FAA SAFO 16015 as supported by EASA. There are no mandatory compliance deadlines, but affected operators are advised to adopt these best practices promptly to reduce the risk of inadvertent load release.

Summary

EASA Safety Information Bulletin 2016-18R1 is a revision of the original SIB 2016-18 concerning dynamic rollout during hoisting and external sling load operations for rotorcraft operators. It addresses the risk of inadvertent load release caused by dynamic rollout or ring reversal, particularly involving personnel-carrying device systems (PCDS) and dual-lock hoist hooks. The bulletin references advisory materials from CASA and FAA and applies to rotorcraft performing these specific operations.

What changed

This revision of EASA SIB 2016-18 includes new references to CASA Airworthiness Bulletin 25-033 and updated EASA advisory material on PCDS following an occurrence involving a dual-lock hoist hook where the PCDS ring and webbing depressed both latches, causing a load release. It updates the safety information to reflect these findings and recommendations but does not introduce mandatory regulatory actions.

Why it matters

The bulletin highlights a safety concern that could lead to accidental load release during hoisting or sling load operations, which is critical for rotorcraft operators to understand and mitigate. Although not mandating regulatory action, it informs operators and maintenance teams about potential risks and encourages proactive safety measures to prevent accidents. Compliance teams benefit from awareness of evolving advisory materials to maintain operational safety.
