All AWI mufflers, shrouds, and exhaust stacks come with data tags for each part, specifying the company that manufactured the unit, its PMA number, installation eligibility and the serial number of the part. The FAA certified replacements can be installed by any A&P mechanic. Each component produced by AWI comes with a 12 month, unlimited hours warranty against workmanship defects. The total life of the parts varies with the maintenance program for the aircraft and the types of engine operations.
AWI has earned over 450 PMA’s in the past 26 years for exhaust components in General Aviation single and twin engine piston aircraft. For more information on all AWI exhaust systems, engine mounts and their capabilities for prototyping, visit AWI-AMI.com.
