Nicrocraft Facility

Nicrocraft Aircraft Exhaust Systems are both newly manufactured and overhauled with FAA – PMA / STC approved parts. Nicrocraft Systems can be found in Cessna, Beechcraft, Mooney, Piper and other aircraft.  We have over 82 Models and 675 Parts.

High temperature nickel brazing and Nicrobraz® brazing filler metal, originally invented by Wall Colmonoy, is used extensively in the construction, which is fundamental to weight reduction while maintaining optimal strength.  

The Nicrocraft engineering process has been carefully designed:

  • To allow for longer service life.

  • To ensure proper alignment.

  • To rigorously test for leaks since exhaust system failures can cause carbon monoxide poisoning, loss of engine power and even fire.

  • To reduce the risk of stress cracking and increase the overall corrosion resistance of the material.

Nicrocraft™ Aircraft Exhaust Systems are manufactured by Wall Colmonoy Aerobraze Oklahoma City to the highest quality standards. We offer the Quality Assurance Certifications of:

  • ISO 9001 certified

  • AWS D17.1:2010 (welding)

  • FAA Repair Station # BG2R715K

  • FAA-DER – Exhaust Systems
