REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES
The track 4 sensor strut aims at detecting any abnormal flap movement due to mechanical drive station
elements disconnection at flap track 4 or track 5.
Recent investigations revealed that current standard would be unable to provide failure detection
information in case of down drive shaft disconnection. Undetected down drive shaft disconnection may
lead to complete flap disconnection in the case of additional failure on the remaining flap drive station.
The track 4 sensor strut attachment bolts are not expected to sustain the loads induced by a down
drive disconnection at track 5.
Repetitive visual inspections of the down drive components at track 4 and the track 4 sensor strut will
ensure the integrity of potentially affected outboard flap drive station elements.
This Inspection Service Bulletin provides instructions for repetitive visual inspection of the down drive
components at track 4 and the track 4 sensor struts of the wings. In case of findings at track 4 sensor
strut, inspection of the driving components of track 5 will be required.
The accomplishment of this Inspection Service Bulletin will allow to confirm the integrity of the
potentially affected outboard flap drive station elements, keeping adequate level of airworthiness and
safety, until a new sensor strut is available.
The Operational/Maintenance Consequences of this Service Bulletin are covered by the update of the
