REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES
This Service Bulletin is published to advise all operators of A330 aircraft
equipped with PRATT & WHITNEY engines of the issue of the PRATT & WHITNEY
Service Bulletin No. PW4G−100−78−78.
Several A330 operators have experienced cracking on the thrust reverser latch
beam gussets adjacent to the aft cascade ring attachment. Repair proposal and
production modification consist in reinforcing the gusset by the addition of two
steel angle brackets.
This repair has already been validated on the hinge beam gusset that experienced
similar cracking.
The substantiation of this repair/design change has been established using
ground tests and previous hinge beam subcomponent test results.
All affected parts have to be retrofitted prior the thrust reverser have
cumulated 8,000 cycles or withing 1,500 cycles from the release of the PRATT &
WHITNEY Service Bulletin, whichever occurs the later.
The repair/design change consists in :
− Cutting into the latch beam gusset,
− reinforcing the latch beam by addition of steel brackets mechanically fastened
to the latch beam gusset.
Accomplishment of this Service Bulletin will prevent cracks development on the
thrust reverser latch beam gussets.
Accomplishment of this Service Bulletin is recommended prior the thrust reverser
have cumulated 8,000 cycles or within 1,500 cycles from the release of the PRATT
& WHITNEY Service Bulletin, whichever is later.
