During minor repairs to a laminated fiberglass panel, what is typically the third work procedure?

The third work procedure in the context of minor repairs to a laminated fiberglass panel involves mixing the resin according to the applicable technical order (T.O.). This step is crucial as it ensures that the correct type and proportion of resin are used for bonding and repairing the panel effectively. Using the specified resin is essential for ensuring durability and maintaining the integrity of the fiberglass structure, which is vital in low-observable aircraft applications where performance and stealth characteristics are critical.

Before this step, inspections and preparations, such as identifying damage and trimming excess fiberglass, typically occur. Following the mixing of resin, subsequent procedures would involve applying it, often followed by additional steps like reapplying a gel coat. By adhering to the technical orders, the technician ensures consistency and quality in the repair process, which enhances the reliability of the aircraft's structural components.
