Our Specialties



We now have an FAA approved repair procedure for all makes and models of aircraft spinner cone repair and backing plates. Certificate number XKKR436L. K and K Precision Welding worked with the FAA for two years testing several scenarios with a 100% success rate. All spinner cones and backing plates are returned with a maintenance release and yellow tag.

Specialties of K and K Precision Welding include but are not limited to:

  • Aircraft spinner cone repair
  • Fuel and oil tanks
  • Air boxes
  • Bulkheads and fuselages
  • Crew ladders
  • Struts and panels
  • ​Trunnions
In addition to contemporary aircraft, K and K Precision Welding also caters to restoration projects. "We repair a lot of panels for restorations. These panels usually have to be fixed because it is very difficult to find replacements." Recent restoration aircraft include World War I and II warbirds such as the P-51, T-6 and Stearman biplane.
