| Subject: | Re: Accident report from Australia |
In the UK we are subject to a mandatory 600hr Life Extension programme. That is
at 600 hours flying time OR 3,500 Landings OR Ten years calendar life. Wings
off: fuel tanks out and ailerons off. Tailplane off: horiz and vert plus elevators
and rudder. Main and nose gear off and finally, Engine bearers off.
The various attachment points are given a thorough visual inspection as are various
noted areas inside the wings (hence tanks out). All the main attachment
points are also given a NDT inspection as are all the attaching bolts (AMOC, they
can be renewed) but the aileron bolts MUST be renewed.
Its quite intense. We got caught on calendar time, we were nowhere near the landings
or flying hours allowed.
Elevator pulley. A couple of years ago I found cracks in ours exactly like the
ones in the example shown in the accident report and changed our to a steel pulley
using a CAA Minor MOD (however there was debate as to whether, in fact,
it should have been a Major MOD) anyway, ours was Minor this means we have to
continue to perform the annual crack inspection regardless. Had we gone down
the Major MOD route AND the CAA had agreed to it and written it into the MOD .
. . we might have been able to discontinue the annual pulley inspection but,
to be frank, it doesn't take long to do and you have the fairings off anyway so
it is no real burden.
