Frequently Asked Questions about Smoke Systems

The answers to the smoke system questions we hear most.

Smoke oil capacity is the only difference.
Any system that will fit in the desired installation point will work in your aircraft.
The FAA requires that an STC be specific to a particular aircraft make and model. Given the number of different aircraft makes and models worldwide, it is not practical for Smoking Airplanes to get an STC on all aircraft that use our system.
Smoking Airplanes smoke systems are installed under FAA 337. An Inspection Authorized Airframe and Power Plant mechanic can prepare the 337 for your aircraft.
There are thousands of smoke systems flying in the United States under FAA 337 and we have not be advised of any customer difficulties related to the FAA 337.
Request a copy of the FAA 337 from the Seller. The aircraft should not be flown with the smoke system without a completed and approved FAA 337.
Yes, however the aircraft should not be flown with the system installed until the inspection is complete and the FAA 337 signed off by the Inspection Authorized Airframe and Power Plant Mechanic.
Yes, provided that the system is inspected by an Inspection Authorized Airframe and Power Plant Mechanic and the required FAA 337 is completed and signed off. The aircraft should not be flown with the smoke system without a completed and approved FAA 337.
No, under no circumstances should an aircraft be flown without an approved FAA 337.
Most foreign jurisdictions have an approval process similar to the FAA 337  in the United States.  Our systems have been approved for flight in the United Kingdom, European Union, Australia, Latin and South America as well as Asia.  We recommend that your local flight jurisdiction be contacted prior to ordering to verify what approvals will be needed.  While our foreign customers have not experienced difficulty with gaining approval, given the number and variations in regulations it is best to verify your own circumstance prior to ordering.  Please contact Smoking Airplanes with any questions related to foreign approval.

Yes. The turbo prop upgrade is needed for a turbine helicopter. Please contact Smoking Airplanes prior to ordering if you would like to install the system in a turbine helicopter.
Yes, however our system should never be used on a public road way or in any matter that would compromise public safety or contrary to law. User is responsible for complying with all applicable laws. If you wish to install a smoke system in an automobile please contact Smoking Airplanes.
Where the proposed installation point is tight, we recommend that a cardboard mockup be made of the system using the dimensions of the desired system from our web page to verify fit. A glue gun and an old cardboard box will allow you to quickly make a mockup.
If the aircraft has dual exhaust or headers then a second injector is recommended for best smoke. For a single exhaust a second injector is not needed and will not improve the quality of the smoke trail. A third or more injectors are generally never needed.

We recommend Smoking Airplanes smoke oil or any other smoke oil that is chemically equivalent. No other oil is approved. The use of anything but the recommended oil can and likely will destroy the smoke system and create an extreme safety hazard, potentially resulting in death. Please click here for material safety data sheet related to our smoke oil.
No, colored smoke oil can damage the smoke system. Only Smoking Airplanes smoke oil or chemically equivalent smoke oil is approved.
There are many different recipes for colored smoke and none have been approved for our system. Our testing has shown that colored smoke can plug the oil filter, check valve and the injectors. Further, colored smoke can stain or damage aircraft paint. There is also a risk of staining spectators or property on the ground if colored smoke is used at lower altitudes. For these reasons its not approved for use in our systems.
