Aircraft Repair

Sitec is well known within the Airbus Customer Service Industry for supplying experienced design and stress engineers to support Aircraft Wing Repair Engineering.

Since 2005 when we were awarded our Customer Services Contract, Sitec has been responsible for successfully supporting many high profile and complex repair programmes such as A380SB Rib Boom Retrofit Programme, A380EF Test, A380 MSN00014 Engine Failure, A400M, and in-service daily wing repairs on Single Aisle, Long Range and Widebody aircraft.

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, advise them on the best repair solution and work 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 by Airbus DOA via Sitec Repair Engineering Office.
