What to do

Operators of AB139 and AW139 helicopters with affected Breeze hoist assemblies must perform a rated load check before the next hoist operation after 10 August 2021. If discrepancies are found, corrective actions approved by Leonardo must be followed. Only serviceable hoist assemblies may be installed from 10 August 2021 onward.

Summary

EASA Airworthiness Directive 2021-0186R1 is a correction to the emergency AD addressing the rated load check (RTC) requirement for Breeze external hoist assemblies installed on Leonardo AB139 and AW139 helicopters. It applies to specific Breeze hoist assembly part numbers, particularly those with replaced hoist cables or stored over 12 months. The AD mandates a one-time RTC to ensure the integrity and safe operation of the hoist assemblies.

What changed

This revision corrects the reference to the AW139 Maintenance Publication manual and updates the issue date of the Leonardo Emergency Alert Service Bulletin 139-679. It supersedes the original Emergency AD 2021-0186-E by clarifying these details without changing the core requirements for the rated load check.

Why it matters

The AD ensures that operators verify the safety and reliability of external hoist assemblies, preventing potential failures that could lead to loss of external human cargo during hoist operations. Compliance is critical for maintaining airworthiness and operational safety of affected helicopters equipped with Breeze hoists.
