Bombardier has issued SB 604-52-007 for Challenger CL-600-2B16 models to address corrosion in the "lower structural elements of the passenger door". Bombardier states that purpose of this Service Bulletin, which effects serial numbers 5301 to 5665, is to remove the epoxy ramp and repair corrosion. The epoxy ramp around the MED, which has been found to deteriorate over time, can allow for moisture to enter which can lead to corrosion damage. Additional modifications include adding draining holes to allow access to facilitate scheduled inspections. On this particular door, corrosion was identified on the MED hinge, the forward and aft lower corners, the lower center channel and hinge fairings.

The epoxy ramp was removed as per the instructions to further assess the state of the corrosion damage and begin repairs. The deterioration of this epoxy is likely the source of the trapped moisture which contributed to the spread of the corrosion. Corrosion thrives under humid environments where deterioration of metal can occur relatively quickly. One of the best ways to prevent corrosion damage is to ensure the area in question is protected from moisture as much as possible. Sealant was added in select areas to further protect the area from moisture.

Some aircraft maintenance events require skilled Aircraft Technicians to coordinate with NDT Technicians to satisfy the requirements of a repair or service bulletin. Usually this requires calling multiple companies and coordinating between their schedules which can extend downtime for maintenance. SEAL Aviation offers many of the services aircraft operators need to maintain aircraft including Fuel Leak Repair and Maintenance, Structural Repair, Non-destructive Testing, aircraft parts inventory and much more. SEAL Aviation Combined Services work together to provide the required services, personnel and supplies to reduce downtime and cost for our customers.

This Gulfstream G200 repair is a great example of how SEAL Aviation Combined Services work together to benefit our customers. Service Bulletin 200-57-426 Wing Flaps Fairing Seal Repair addresses flap fairing debonding and moisture intrusion that might lead to lower wing skin corrosion, cracking on both wings and reduced structural integrity of the wings. This Service Bulletin requires G200 aircraft to have corrosion removed on certain areas of the lower skin on both wings. Once the corrosion has been removed, the fairings are then resealed with fillet sealant and the area is then inspected by a Non-destructive Testing Technician.

SEAL Aviation provides all the aircraft maintenance services required to address Service Bulletin 200-57-426. The SEAL Aviation Structural Repair Team can remove any identified corrosion in coordination with the Fuel Leak Repair Technicians to reseal the fairings.

The article titled "Microbiologically Induced Corrosion in Wing Fuel Tanks" appeared in the April 2020 issue of The Gulfstream Journal and details how MIC has the ability to progress quickly leading to expensive wing repairs. If left unchecked Microbiologically Induced Corrosion can cause damage such as pitting on hi-locks and the wing structure. Gulfstream states that routine microbial contamination testing and consistent draining of the aircraft fuel tanks is key to maintaining a healthy fuel system. SEAL Aviation can perform an inspection of your fuel tanks to determine if your Gulfstream is experiencing the presence of corrosion due to Microbiologically Induced Corrosion. SEAL Aviation can also help you test for microbial contamination to ensure your fuel system remains healthy.
