Nicrocraft has received FAA Parts Manufacturer Approval (PMA) certification for Cessna twin exhaust stacks, expanding its portfolio of FAA PMA-approved parts for the general aviation market.

The Cessna twin exhaust stacks are manufactured from heat-resistant 321 stainless steel to deliver durability, corrosion resistance and long-term reliability. Designed to meet or exceed original equipment performance standards, each exhaust stack is backed by a 12-month, unlimited-hours warranty from the date of installation.

The newly approved FAA PMA replacement parts include Nicrocraft part numbers WC9910295-13 (exhaust stack, left-hand) and WC9910295-14 (exhaust stack, right-hand). The exhaust stacks are approved for installation on Cessna 310R, 340, 340A, 414 and 414A Chancellor aircraft, as well as Cessna 401A and 401B, 402A, 402B and 402C, and T310P, T310Q and T310R models.

“We are excited to add exhaust stacks for twin Cessna aircraft to our growing portfolio of FAA PMA products,” states Jimmy Lockbaum, business development manager, Nicrocraft. “This addition reinforces our commitment to providing high-quality replacement parts for the general aviation community. We look forward to bringing additional PMA-approved solutions for this aircraft family in the months ahead.”

Nicrocraft exhausts and heat exchangers are engineered to deliver reliable performance, operational efficiency and extended service life across a wide range of aircraft.
