REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES

The hydraulic system accumulator, type 5" (PN 3059103-1 or 3059103-2 or 3059103-8 or 3059103-9) is

installed in each of the three hydraulic systems.

There was a design change to the accumulator in 1984 but the part number remained the same and

the serial number from the time of design change was not tracked.

The accumulator was changed from a 4 piece unit with 3 welds (so called "pre 1984") to a 2 piece unit

with 1 weld ("post 1984").

The welding process was improved providing a higher strength shell material and overall more reliable

design.

Further to a recently performed particular risk analysis the conclusion requires that post 1984

accumulator must be installed on the GREEN hydraulic system as it is in a zone particularly at risk to

system damage should an accumulator burst occur.

This Service Bulletin requires performing a detailed inspection of the GREEN hydraulic system

accumulator and replacing pre 1984 design with post 1984 design.

Accomplishment of this Service Bulletin will ensure that a post 1984 hydraulic accumulator is installed

on the GREEN hydraulic system. Simultaneous accomplishment of Service Bulletin No. A310-29-2100

(installation of warning placard) will avoid inadvertent installation of a pre 1984 accumulator.

Accomplishment of this Service Bulletin requires simultaneous accomplishment of the

(1) History

The hydraulic system accumulator, type 5" (PN 3059103-1 or 3059103-2 or 3059103-8

or 3059103-9) is installed in each of the three hydraulic systems.

There was a design change to the accumulator in 1984 but the part number remained

The accumulator was changed from a 4 piece unit with 3 welds (so called "pre 1984") to
