Component repairs

To arrange for repairs of component parts, Sukhoi will evaluate the needs of the repair facility regarding necessary equipment, documentation and qualifications of the technical personnel. Sukhoi will produce technical and business proposals for repairs of component parts in Russia and/or on site.

Sukhoi will develop a plan and schedule for repairs (general, light, as required, etc). Sukhoi will compile a list of additional equipment needed to implement the Repairs Plan based on the facility's retrofitting requirements. Sukhoi will compile lists of component parts required for modification.

Repairs Plan optimization

To optimise the Repairs Plan it is necessary to:
− compile lists of the design problem areas to be targeted during inspections.
− develop a Diagnostics and Troubleshooting Procedure.
− draw up a list of diagnostic and trouble-shooting tools required to implement the Repairs Plan.
− develop an online reference database for airframe diagnostics.

Optimise the repair replacements list

Based on the testing results and field experience in operating aircraft of specific type, Sukhoi will produce:
- lists of prescribed tasks and replacements during repairs,
- lists of specific tasks and modifications,
- lists of materiel required for specific tasks and modifications,
- Chief Designer Technical Requirements (CDTR).

Development of life expectancy datasheet

In the course of aircraft operation or repairs, following a Customer's request, Sukhoi will produce life expectancy datasheets based on research into aircraft field performance and operational environment and onboard equipment reliability.

The datasheet will give an updated list of units with limited life, specify the scope and frequency of diagnostic and visual inspection checks, as well as provide a list of modifications to be introduced into the design.

Development of aircraft diagnostics procedures

Based on research into test results, field experience and aircraft operating environment and onboard equipment reliability, Sukhoi will compile lists of the design and equipment problem areas to be targeted during diagnostics and visual inspection checks. It will produce a list of diagnostic and troubleshooting tools. It will develop or upgrade the diagnostic and troubleshooting procedures.
