Found an error in the technical content?
This is the message we most want to get. Tell us the page, the figure you think is wrong, and what you believe it should be — with the document and paragraph if you have it.
We will check it against the primary source, correct it if you are right, and say on the page that it was corrected. Reference content that quietly edits its mistakes is not worth trusting.
Distributors and manufacturers
If you sell parts, materials or tooling for aircraft structures and want to be listed, get in touch. What we will want to know: what you stock, which regions you ship to, and whether you have an affiliate or dealer programme.
What we will not do is list you without checking that the links work and the stock is real. Two distributors are linked today and both were verified by hand.
Everything else
Training enquiries, corrections to the legal pages, or questions about how something on this site was sourced — same address.
We cannot advise on whether a specific repair is airworthy on a specific aircraft. That is a question for your certifying authority and the applicable approved data, and no email from us can substitute for either.
