Wall Colmonoy has received FAA-PMA certification on the Nicrocraft Piper PA-28-181 Archer TX III forward and aft muffler assemblies.
The mufflers are constructed of heat resistant 321 stainless steel. The baffles are made of Inconel alloy to provide maximum reliability, corrosion resistance, and service life, according to company officials.
Nicrocraft FAA-PMA parts are eligible for installation on Piper PA-28-181 Archer TX III, for serial number 2843001 and on, with the Lycoming O-360-A4M engine.

“Flight schools and operators of Piper Archer TX III aircraft have been asking for a higher quality affordable alternative to the OEM, and we listened,” said Jim Lockbaum, business development manager for Nicrocraft.
Wall Colmonoy Corporation in Oklahoma City manufactures its exhaust products under the trademarked name Nicrocraft and distributes around the globe. Nicrocraft brand exhaust components carry a 12-month, unlimited hour warranty from the date of installation, company officials note.
