REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES

One fastener, at FR24 between STRG 25/26 RH side was discovered missing in production.

This missing fastener, a 4 mm diameter aluminium rivet (ASNA2050DXJ040), normally connects

together FR24 and FR24 Tee.

This Service Bulletin calls for a Rototest inspection of the two adjacent fastener holes and some

corrective actions if crack is found or not.

Accomplishment of this Service Bulletin will contribute to ensure the structural integrity of the aircraft.
