Aerostructures

At Lee Aerospace, we have over 50,000 square feet of assembly room floor and a highly trained assembly work force dedicated to aerostructures. We can assemble anything from small bench top assemblies like wire bracket assemblies, to large assemblies like pressurized fuselage assemblies. The details for these assemblies are put together using bench type tools like Assembly Jigs (AJ) up to Floor Mounted Assembly Jigs (FAJ). Our assembly techniques include installation of solid rivets, pull fasteners, tool-drilled holes, hand-drilled holes, coordinated pilot holes (ATA), close tolerance hi-lok holes, wet installed fasteners and an automated riveter. We are qualified to assemble structural “wet” wing assemblies that have to be sealed to comply with fuel tank requirements. We also seal pressurized fuselage sections that have to pass aircraft pressure tests with no leaks.
Quality inspection of assemblies employs a progressive buy off technique. Sub-assemblies are bought off before they are fed into larger assembly tools. Detail parts are bought off to Manufacturing drawings describing the pilot hole manufacturing plan.  Our current assembly programs include:

  • Wing leading edge assemblies
  • Wing spar assemblies
  • Pressurized fuselage assemblies including AFT pressure bulkhead
  • Aft tail cone assemblies including engine attach and vertical fin attach fittings
  • Control wheel assemblies including wire bundle soldering and final functional testing
