REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES

Airbus has analysed in-service events reported by Messier-Bugatti-Dowty concerning some cases of

NLG and MLG Door and Leg Uplock spring ruptures on A300, A310 or A300-600 aircraft.

Springs within the uplock are used to either lock the gear or the door in the up position or to participate

in emergency mechanical unlocking.

The springs are positioned in pairs and in case of rupture of one spring the other one remains to fulfil

the function.

The rupture of one spring has no consequence on the operation of the uplock whereas the rupture of

both springs will disable the locking function or the emergency unlocking function..

This Service Bulletin is published to advise all operators of the issue of MESSIER-BUGATTI-DOWTY

Service Bulletin No. 470-32-206 and MESSIER-BUGATTI-DOWTY Service Bulletin No. 470-32-880.

This Service Bulletin includes a detailed inspection of the NLG and MLG Door and Leg Uplock springs

and replacement in case of finding.

Accomplishment of this Service Bulletin will ensure correct operation of the NLG and MLG Door and

Leg Uplocks.

Table 2

This Service Bulletin has been classified Mandatory. It is expected that an Airworthiness

Directive (AD) published by the European Aviation Safety Agency (EASA) will be issued

to confirm this classification. It is anticipated that the AD will confirm the (thresholds

and/or intervals and/or date) given above but reference should be made to the AD for

confirmation of the mandated accomplishment timescale.

F. APPROVAL

The technical content of this document is approved under the authority of Design

Organisation Approval No. EASA.21J.031.

If an aircraft listed in the effectivity has a modification or repair embodied that is not of

AIRBUS origin, and which affects the content of this Service Bulletin, the operator is

responsible for obtaining approval by its airworthiness authority for any adaptation necessary

before incorporation of the Service Bulletin.

G. MANPOWER

The manpower estimates given in this Service Bulletin are based on the direct labor cost to

do the work. These estimates assume that the work will be done by experienced personnel,

and may need to be revised upwards to suit operator’s circumstances. The estimates do not

include the time to prepare, plan or inspect the work. Manufacture and procurement of parts

and tools, drying times for paints, sealants, etc., and general administration work are also not

included.
