Saab AB, Support and Services (Formerly Known as Saab AB, Saab Aeronautics) Airplanes
This AD applies to all Saab AB, Support and Services (Formerly Known as Saab AB, Saab Aeronautics) Model 340A (SAAB/SF340A) and SAAB 340B airplanes; and Model SAAB 2000 airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Saab AB, Support and Services Model 340A (SAAB/SF340A) and SAAB 340B airplanes; and Model SAAB 2000 airplanes. This AD was prompted by reports that certain nose landing gear (NLG) door attachment bolts are susceptible to hydrogen embrittlement. This AD requires replacing certain NLG door attachment bolts with serviceable bolts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency (EASA) AD 2020-0149, dated July 7, 2020 (EASA AD 2020-0149).
(1) Where EASA AD 2020-0149 refers to its effective date, this AD requires using the effective date of this AD.
(2) The “Remarks” section of EASA AD 2020-0149 does not apply to this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
