Leading Edges
Comtek repairs composite leading edges for a variety of aircraft, including the DHC-8 Q series, ATR-42/72 and the Emb-120. In the case of the DHC-8, Comtek has teamed with Bombardier to develop new repair designs that greatly expand the ability to repair damaged leading edges and return them to service. For example, the damage shown above is readily repairable by Comtek in accordance with an approved de Havilland RD.
Instead of having to buy new leading edges, our DHC-8 customers benefit from a leading edge service package which includes removal of the old de-icer boot, any needed repairs, the installation of a new de-icer boot, an application of anti-static paint and polishing the boot with spit shine. The cost savings to our customers are substantial!
An ongoing problem with leading edges has been the damage to the outer plies caused by multiple de-icer boot removals. Comtek has solved this problem on the DHC-8 through an overhaul process which completely replaces the outer ply with new material, and adds a second ply to serve as a sacrificial barrier to moisture and solvents. The new outer ply not only protects the structural integrity of the part, but it can be removed by a simple maintenance action if it becomes damaged, so that the leading edge can be returned to service right away.
