WRAITH GEARBOX.

There have already been three complaints of failure of the gear change mechanism on Wraith due to excessive engine movement allowing the gear change pendulum to come out of the selector. There is no doubt that this state of affairs would be improved by a new torque reaction control.

We have started a Standardisation Sheet for this and we recommend that scheme GCD.1216 should come on at the first in 'C' series.

I doubt whether the new scheme can come in on 1st hundred as something are actually made By
