Certification Data Public Information?

[DanH]

Is data submitted to the FAA as part of the certification process for an engine, airframe or appliance considered to be public information?

Yes. If you get the N-number for the airplane that was used for certification you can order all the records of anything submitted to the FAA. FAA records are public-domain.

Yes. For an aircraft, it can be obtained from the FAA with the N-number and Serial Number. The FAA Registry charges $10 and will mail you a CD for the aircraft. A DAR should have an account and be able to get a eCopy of aircraft records on his computer for around $3.50. An FAA Inspector get the info FREE on his computer. The PDF file that the FAA puts is protected but there is low cost software available that can remove the protection.

How about engines and appliances?

Any data submitted to the FAA is public data.

A call to the responsible ACO office for the TCDS should be able to tell you how to get to whatever it is you're looking for.

While I can't speak directly to the FAA rules, I can tell you that with my government agency, we deal with corporate proprietary data all the time - and just because the "submit it to the government" doesn't make it public. In many cases, we can't even share it to other government workers if they aren't directly required to know it - and certainly, it can't be shared with other contractors.

Certainly the data that is actually on a TCDS is public - but I wouldn't automatically assume that EVERYTHING submitted to the FAA is releasable to anyone.

See http://registry.faa.gov/aircraftinqu...m_Inquiry.aspx for information that is normally available to public.

It does include engine type and manufacturer.

Its one thing if intellectual property is involved, patentable material for example, but another if its performance data which is probably what Dan is looking for.

Engine information is what I have in mind here, although airframes and accessories are of interest.

What kind of engine information? Consider FAR 33.43 through 33.57. The work done to satisfy these FARs is not a contract to supply a product or service to the government, but rather a requirement of law relating to public safety. I assume this data is submitted to an engineering office at the FAA for review and approval. Can a member of the public obtain the data?

Keep in mind that Lycs were certified under the old CAR regs. So it may be that the vibration data that is now required wasn't the case back then.
