modified the thrust-reverser actuation system of production A350-900s after a
failure of a locking mechanism on an in-service aircraft.
actuator was removed from the jet after several failure messages, and
investigators found that it failed a primary lock integrity test, said the
European Aviation Safety Agency.
that the component can be affected by internal contamination from carbon dust,
and that this can affect the retention capability of the actuator.
EASA said 2
out of 3 retention mechanisms of the thrust reversers can potentially be
affected by the problem, which would leave only the 3rd system – a lock
employing a different design – for retention.
introduced a new thrust-reverser actuation system standard into A350
production, after Goodrich corrected the problem.
ordered in-service A350s to be modified to the same standard, within 750 cycles
since first flight.
Aerospace Europe (part of UTC Aerospace Systems' Aerostructures) is producing
the thrust reversers in a new dedicated building at its Toulouse site, with a 50.000-square-foot thrust
reverser robotic production area with a moving assembly line.
is providing all three members of the A350 XWB family's nacelle and thrust
reverser system, wheels and carbon brakes, air data system and ice detection
system, external video system and cabin attendant seats.
for the new A350-1000, Goodrich is providing the main landing gear.
