Outsourcing in the division started in 2003. Since then the Division has embarked upon selecting and creating base of sub-contractors for outsourcing of precision components, tooling and test equipment.
 
In view of emerging business scenario, the Out-sourcing is the need of the hour and is required to handle higher loads of existing and new projects being undertaken in the HAL Lucknow. The work could be performed by the third party either within or outside HAL premises.
 
Outsourcing is done primarily in the following areas:
  • Manufacture of Detail parts including specialized machining processes like Honing, Lapping, Shot Peening, Gear cutting, Gear Grinding etc
  • Process operations including heat treatment, Tungsten Carbide Coating, Titanium Nitride Coating, Laser Beam Welding, Electron Beam Welding etc.
  • Tooling, Jigs & Fixtures etc.
  • Painting, De-painting, Cleaning and dismantling of LRUs, etc.,
  • Third party inspection in HAL as well as at subcontractor’s works
  • In-sourcing of lapping, Machining, CNC machining and programming, Painting, NDT, Dismantling & Cleaning activities
 
The components are classified in various categories like A, B & C depending upon the criticality of the operations. Depending on the capacity and capabilities of sub-contractors, tenders are issued to sub-contractors registered in the Division.
 
Organizations with established facilities &capabilities, willingness to learn and excel in producing aeronautical quality product are encouraged for outsourcing of components, required for various airworthy projects.
