DON'T PUT UP WITH THIS!

Our friendly and knowledgeable staff is available to answer any questions you may have regarding exhaust systems, components or custom systems for experimental aircraft.

Exhaust systems on aircraft are often overlooked during routine and annual inspections. Most exhaust systems are produced with type 321 stainless steel. Although stainless steel has a very high heat tolerance it will fatigue due to rapid heating and cooling cycles. Damage is not always obvious. It is very important to remove all shrouds and shields to permit a full inspection. Thoroughly clean and pressure check all heat exchangers for leaks. Here are some tips in looking for exhaust damage.

• Exhaust stains - gray, yellow, red and black
• Cracked or thin exhaust flanges
• Warped exhaust flanges
• Cracked end plates on mufflers and heat exchangers
• Loose connections
• Frozen or leaking slip joints
• Bulging, distorting or deteriorated areas
• Thinned, pitted or worn areas
• Internal baffling missing, loose or distorted
• Hidden damaged areas that lie under gussets or stiffeners
