SEAL Aviation can perform Falcon Service Bulletin 329-R4 Wing Tank Modification, anywhere in the world.

Dassault Falcon has updated Service Bulletin 329 to revision 4 Wing Tank Modification for Falcon 900EX, 900EX EASy and 900DX models. 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.

Complying with SB329-R4 requires removing the structural lower wing panel, installing drainage capability, installing the boundary between ribs No. 4 and 5, and finally sealing the boundary and performing a test for leakage.
