EASA AD 2020-0017
Equipment / Furnishings — Hoist Assembly — Inspection
Summary
EASA Airworthiness Directive 2020-0017 is an airworthiness directive addressing the inspection of hoist assemblies on PZL W-3A helicopters. It specifically targets the stainless steel cable with Part Number 712952 installed in Collins Aerospace Electric Hoists, Part Number 76378-500. The directive mandates repetitive inspections to detect wear and potential failure of the cable near the swaged terminal.
What Changed
This new airworthiness directive introduces mandatory repetitive inspections of the affected hoist cable on PZL W-3A helicopters to identify wear caused by flickering movement during flight. It requires replacement or maintenance actions if defects are found and sets conditions for installing affected hoists on helicopters. The directive also defines helicopter groups based on hoist installation status and introduces part installation requirements.
Why It Matters
This directive is critical for aviation professionals to prevent potential cable failure that could lead to in-flight loss of the hoist load, risking injury and damage to the helicopter. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and safety. The directive helps mitigate risks associated with worn hoist cables and ensures continued safe operation of the affected helicopters.
What To Do
Operators of PZL W-3A helicopters with affected hoists must inspect the stainless steel cable within 25 flight hours after 2020-02-13 and repeat inspections every 25 flight hours thereafter. If wear or defects are found, the cable must be replaced or the hoist removed before further flight. Installation of affected hoists on helicopters without them is allowed only if the hoist is new, overhauled, or inspected within 25 flight hours prior to installation.
