WING TANK MODIFICATION ________________________________________________________________________________ 1 . PLANNING INFORMATION A . EFFECTIVITY This Service Bulletin is applicable to MYSTERE–F ALCON 50 aircraft with serial numbers 2 through 352.
B . REASON An 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 in the event of such an exceptional occurence by installing a sealed boundary between ribs No. 4 and 5 in front of the rear wing spar.
C . DESCRIPTION The operation consists in:
– removing the structural removable lower wing panel, – installing a drainage capability, – installing a boundary between ribs No 4 and 5, – applying a sealant around the boundary , – performing a test for leakage, – replacing the instruction placards on the wings and on the refueling door .
The Accomplishment Instructions and the tests are included in the five Appendices to this Service Bulletin.
D . COMPLIANCE Mandatory:
Compliance with this Service Bulletin should be done no later than 12 years and 6 months of its release date.
It is anticipated that this Service Bulletin will be rendered mandatory by an EASA Airworthiness Directive. The Airworthiness authorities of other countries may also elect to mandate compliance with this Service Bulletin and compliance timelines will be established by those authorities.
Each person applying this Service Bulletin must have successfully completed a training program. For more details refer to the training section of paragraph F .
