What to do

Operators of SA 330 J helicopters without Airbus Helicopters modification 07 27362 must modify the collective lever secondary stop by replacing the covering plate with self-adhesive tape. This modification must be completed within 100 flight hours or 12 months from the effective date of 7 April 2022, whichever occurs first. The modification should follow the instructions in Airbus Helicopters Alert Service Bulletin SA330-67.27.

Summary

EASA Airworthiness Directive 2022-0056 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Airbus Helicopters SA 330 J models. It addresses a potential flight control issue related to the main rotor controls, specifically the collective lever's secondary stop covering plate. The directive mandates a modification to ensure continued safe operation of the affected helicopters.

What changed

This new airworthiness directive introduces a required modification replacing the covering plate of the collective lever secondary stop with self-adhesive tape. This change corrects a condition where a rivet could interfere with the collective lever fulcrum, restricting its movement. The modification is detailed in Airbus Helicopters Alert Service Bulletin SA330-67.27.

Why it matters

This directive is critical for aviation professionals because restricted movement of the collective lever can reduce helicopter control, posing a safety risk. Operators and maintenance organizations must ensure compliance to maintain airworthiness and avoid operational restrictions. Compliance also supports regulatory adherence and prevents potential flight control malfunctions.
