Repair Engineering Project

Sitec is well known within the Airbus Customer Service Industry for delivering approved aircraft repairs. 

Since 2005; Sitec has been responsible for successfully delivering in-service daily wing repairs on Single Aisle, Long Range and Widebody aircraft. In addition we specialise in supporting and delivering high profile and complex repair programmes such as A380SB Rib Boom Retrofit Programme, A380EF Test, A380 MSN00014 Engine Failure and A400M.

As part of our 24/7 coverage, we react to ever changing targets using our proactive Aircraft Repair Knowledge (ARK) Tool. ARK details our approaching workload for all engineers on all repair projects across our UK and Bangalore offshore facilities to ensure that customers requirements are met.

We specialise in every aspect of wing repair. A typical repair can be a large multisite wing skin corrosion covering many areas of the wing. Following corrosion removal, some areas may require a repair plate to be designed and justified in order to allow repair plate installation by the airlines maintenance, repair and overhaul facility. Sitec reviews the operator/airline damage reports, advises on the best repair solution and works with them to deliver the optimum repair solution in the most expedient manner. Sitec will analyse the repair statically, perform fatigue and damage tolerance analysis and design the repair solution using a suite of applications available.

The customer will receive approval documents outlining the post-repair inspection programme that have been approved under Airbus DOA via Sitec Repair Engineering Office.
