A Dassault Falcon analysis of rare high-speed runway excursions has revealed that, in case of a main landing gear leg failure due to overloads, the subsequent wing damage may cause a potential fuel spill. The purpose of this Service Bulletin is to prevent such a fuel spill by installing a sealed boundary between ribs No. 4 and 5 in front of the rear wing spar. SEAL Aviation can assist by deploying SEAL Aviation Combined Services for Structural Repair, NDT and Fuel Tank Maintenance to comply with this Service Bulletin. Additionally the SEAL Aviation team has the ability to perform this modification at your location as well as our Fort Pierce, Florida hangar location. Our team of experts possesses the required tooling, parts and manpower to complete this repair quickly and efficiently.
