MODIFICATION CLASSIFICATION
MAJOR None
MINOR None
NOTE: As per EASA IR 21, a minor change is one that has no appreciable effect on the
mass, balance, structural strength, reliability, operational characteristics affecting
the airworthiness of the product. All other changes are major changes.

B. REASON
CONF 001
(1) History
Several cases of A330/A340 Family Forward (FWD) Passenger (PAX) door jamming
during slide deployment tests have been reported, resulting in unsuccessful slide
deployment.
Investigations have shown that these door jamming events were linked to door mis-
rigging.
A sampling done in the Final Assembly Line (FAL) showed that FWD PAX door rigging
values recorded at section level evolve along the aircraft assembly process. Only the
FWD PAX doors are impacted by this inspection because the other A330 Family doors
have a different design.
(2) Objective/Action
This Service Bulletin provides instructions to:
- Check the adjustment of the door in its frame with door closed with open/close
lever in down position by checking the peripheral clearances between the door
and the door frame on each door stop fittings location (total of 16 positions)
- Check the rigging values of the X-guide roller by putting the door in the closed
and up position (door lifted)

SUMMARY

REV 01 Feb 12/25 Page 7
- Check of clearances between the rollers and the guide fittings by putting the
door in the open position (door open/close lever in the up position)
- Check of clearances between the rollers and the guide fittings by putting the
door in the close position (door open/close lever in down position)
- Make sure all door stop screw tab washer are properly bent with the door in open
position, (total of 16 positions).
The above mentioned checks must be performed every 72 months.
In case of any value out of tolerance, the impacted FWD PAX door has to be re-rigged
before next flight.
(3) Advantages
Accomplishment of this Service Bulletin will ensure that the FWD doors rigging values
do not exceed the tolerance limits and will avoid a potential door jamming event.
(4) Operational/Maintenance Consequences

C. REASON
CONF 001
(1) History
Several cases of A330/A340 Family Forward (FWD) Passenger (PAX) door jamming
during slide deployment tests have been reported, resulting in unsuccessful slide
deployment.
Investigations have shown that these door jamming events were linked to door mis-
rigging.
A sampling done in the Final Assembly Line (FAL) showed that FWD PAX door rigging
values recorded at section level evolve along the aircraft assembly process. Only the
FWD PAX doors are impacted by this inspection because the other A330 Family doors
have a different design.
(2) Objective/Action
This Service Bulletin provides instructions to:
- Check the adjustment of the door in its frame with door closed with open/close
lever in down position by checking the peripheral clearances between the door
and the door frame on each door stop fittings location (total of 16 positions)
- Check the rigging values of the X-guide roller by putting the door in the closed
and up position (door lifted)

- Check of clearances between the rollers and the guide fittings by putting the
door in the open position (door open/close lever in the up position)
- Check of clearances between the rollers and the guide fittings by putting the
door in the close position (door open/close lever in down position)
- Make sure all door stop screw tab washer are properly bent with the door in open
position, (total of 16 positions).
The above mentioned checks must be performed every 72 months.
In case of any value out of tolerance, the impacted FWD PAX door has to be re-rigged
before next flight.
(3) Advantages
Accomplishment of this Service Bulletin will ensure that the FWD doors rigging values
do not exceed the tolerance limits and will avoid a potential door jamming event.
(4) Operational/Maintenance Consequences

rollers touch the upper lips of the roller fittings.
c Inspect the peripheral clearances between the door and the door
frame on each door stop fitting at 16 locations:
<1> Measure the clearance F1 between the metallic edge of the
door and the door frame, the values must be between 3 mm +3
mm or -1 mm (0.118 in. + 0.118 in. or - 0.039 in.).
