What Are Those Burn Testing Documents For?

lammability testing, or burn testing as it is called in the industry, is an often misunderstood regulatory requirement. Not understanding it correctly could cost you down the road.

If your aircraft interior was recently refurbished or modified, it is likely that you were given burn test documents by the completions center. These documents contain valuable certification information and you should keep them with the other modification/certification records pertinent to your aircraft.

Federal Air Regulations per 25.853 require that the materials used in corporate jet passenger cabins be “self extinguishing” when exposed to flame in order to enhance the safety of passengers. To meet this requirement, each material used in building or refurbishing an interior must pass certain tests individually, or as an assembly combined with materials on which they are applied. Samples of these materials are subjected to direct flame for a short, specified period of time. The burning material then must self-extinguish within a specified period of time to pass the test. Records of the test results and the origin of the material tested comprise the bulk of the interior burn certification documents.

Burn test certification is required of the entire aviation community. However, you may experience varying levels of compliance at completions facilities around the country. Burn testing is a complex and often confusing process, so you may want to ask a Duncan Aviation representative to explain more about requirements and regulations. Duncan Aviation is happy to provide as much information as you’d like about burn testing.

Aircraft owners have the burden of proof concerning burn testing. Burn testing documents provide the proof of certification required for an owner to demonstrate compliance and may be required in the future to:

1. Prove FAR compliance when an aircraft is being placed on a Part 135 certificate.
2. Prove FAR compliance for pre-buys (when an aircraft changes ownership).
3. Prove FAR compliance when an aircraft is being exported or imported.
4. Verify interior materials for future repairs or replacement.

Understanding the issue and asking questions up front could save you time, money and a lot of frustration.

Falcon 2000 Fly-Away Kit

Check your fly-away kit on your Falcon 2000. Duncan technicians have found that the main gear actuator locking collars P/N TF50B10201A are too long to fit on the Falcon 2000 main gear actuators. The proper locking collar is P/N FGFB910202.

Falcon 50 #2 Engine S-duct Corrosion Warning

As the Falcon 50 fleet ages, Duncan technicians are seeing more corrosion and cracking in the #2 engine S-duct area. This corrosion is usually found during the “2C” & “3C” inspections. Surface corrosion can be found on the lower half of the inside skin of the duct. Cracks can be found on the “Z” shaped angles which wrap around the outside of the duct, on the inside skin or where the anti-icing air manifold is attached to the top of the duct. Dassault has several repair schemes which may be applied to these areas.
