EASA AD 2021-0066
Equipment / Furnishings — Outboard Load System Fittings — Inspection / Re-identification
Summary
EASA Airworthiness Directive 2021-0066 is an airworthiness directive addressing inspection and re-identification of outboard load system fittings on Airbus Helicopters Deutschland GmbH EC135 and EC635 helicopter models. It applies specifically to serial numbers 0886 to 1166 inclusive, excluding certain serial numbers and helicopters with a specific service bulletin embodied. The directive mandates inspection and re-identification of affected fittings with part number L851M2810103 to ensure continued airworthiness.
What Changed
This new airworthiness directive introduces a one-time inspection requirement for outboard load system fittings to identify and re-identify affected parts that are not approved for installation on certain EC135 and EC635 helicopters. It also requires a follow-up inspection of any affected parts found and corrective actions if damage is detected. The directive provides detailed instructions referencing Airbus Helicopters Alert Service Bulletin EC135-85A-086.
Why It Matters
This directive is critical for aviation professionals because the affected fittings, if not identified and inspected, could fail and cause loss of external cargo, posing safety risks to personnel and people on the ground. Operators and maintenance organizations must ensure compliance to prevent potential accidents and maintain regulatory compliance. It also clarifies the applicable overhaul and life limits for these parts, which may not be known to operators.
What To Do
Operators of affected EC135 and EC635 helicopters must inspect each outboard load system fitting before the next operation after 22 March 2021, the effective date. If affected parts are found, they must be re-identified before the next flight and inspected again within 150 flight hours or before the next operation, whichever is later. Any damage found during inspections requires contacting Airbus Helicopters Deutschland GmbH for corrective instructions before further flight.
