Eddy
Current Procedures
During
the overhaul of Hartzell type propellers, a procedure of NDT
(non-destructive testing) is carried out using specialist equipment.
Deltair to date have used a sub-contractor company for this procedure
which with the added burden of freight is expensive and time consuming.
Deltair recently purchased the new piece of equipment to enable the
eddy current procedure to be carried out in-house during the overhaul
of Hartzell type propeller blades.
In addition to the equipment, the qualification of the personnel is
very important and it is mandatory that Deltair work to the letter
of their approvals. Level 2 qualification is required by our Inspection
operatives to carry out this inspection work. The first inspector
has now attended the training course in Wales, he now needs to take
the examination to attain the qualification. A second inspector will
attend the same course in the early part of 2005.
The result of this specialist training will be a lowering of costs
for each Hartzell type propeller overhaul. Deltair are also looking
at the possibility of using these unique skills to carry out the procedure
for other propeller overhaul shops.
