Personalisation is the key to conformity

In most cases, Maintenance, Repair and Overhaul (MRO) centres are the ones under pressure to get the aircraft back in service. 

When receiving maintenance and inspection packages describing the tasks to be completed during an inspection routine, NDT tasks are typically on the critical path, meaning that the airplane cannot be released until all inspections are completed. This implies that NDT not only requires the maintenance team to have an open access, i.e. disassembling airplane sections, but also a time buffer is required in case of any findings that lead to additional maintenance. 

It comes as no surprise that proof of compliance and the absence of false calls are key to avoid any delay. This is particularly true for ultrasonic testing.  Although a very common inspection technique, its usage is not so prevalent within an aerospace context. Therefore, for NDT operators using it on a less regular basis, the task can be daunting when facing the wide selection of parameters available on the testing device. The same goes for ultrasonic signal interpretation that is more challenging by nature. Those aspects call for more precaution as the operator is more prone to deviate from the process or to misinterpret an indication.    

In that context, how can NDT personnel improve their inspections efficiency without compromising the inspection integrity?

The Sonatest WAVE has been designed with built-in conformity and reliability capabilities.  Procedure compliance is ensured, thanks to the WAVE companion software that provides all the necessary tools to the NDT manager in order to create task specific  inspection setups, where only the mandatory parameters are visible in the user interface. This ability of customizing the user interface minimises the risk of human errors by hiding/locking parameters that shall not be changed.

Efficiency is improved when dedicated application setups are available to the operator with a single click, drastically streamlining the workflow. When paired with the interactive scan plan, the risk of a false call is drastically reduced as the A-Scan signal is dynamically layered over the test piece geometry.
