What to do
Affected operators must perform eddy current surface scans for cracks on specified wing fittings and fasteners, conduct torque checks on outer wing-to-center-wing front beam web joint splice angle fasteners, and carry out necessary repairs, retorqueing, or replacements. These actions must be completed by June 1, 2021. Operators should also submit any comments on the directive by June 28, 2021.
Summary
The Federal Aviation Administration's Airworthiness Directive 2021-09-15 addresses Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model 382 series and various C-130 model airplanes, including C-130A through WC-130H variants. This directive mandates inspections and maintenance actions to detect and correct cracks and fastener issues in the center wing forward corner fittings and outer wing-to-center-wing front beam web joint splice angle fasteners. The directive aims to ensure continued airworthiness and structural integrity of these aircraft.
What changed
This new airworthiness directive introduces mandatory eddy current surface scans for cracks on the center wing upper and lower forward corner fittings and fasteners, torque checks on specific wing joint fasteners, and requires repair, retorqueing, or replacement as necessary. It expands applicability beyond the Model 382 series to include multiple C-130 variants. The directive is effective June 1, 2021, and requires compliance by that date.
Why it matters
This directive is critical for aviation professionals because it addresses a structural safety concern that could lead to reduced airplane integrity and potential loss of control if left uncorrected. Operators and maintenance teams must ensure inspections and corrective actions are performed promptly to maintain safe operation. Compliance helps prevent costly failures and enhances overall fleet safety.
