Response text:

I received via fax a copy of your letter BS/990071, addressing the Air Safety Interim Recommendation related to the Saab 340 Stall Warning system. Unfortunately I did not receive the complete fax: some pages were missing.

With respect to the formal responsibility for continued airworthiness of the Saab 340 , I have to inform you that the JAA does not has this responsibility for the Saab 340 nor for any other European Aircraft. This formal responsibility is still at the National Aviation Authority of the State of Design, which for the Saab 340 is Sweden. For the Saab 340 you can contact within the Swedish Authorities [Name, title and contact details supplied]. I would appreciate if you could address the above referred letter to [Name].
