Airworthiness Directive · Amendment 39-19634 · Flight controls
Textron Aviation, Inc. Airplanes
Superseded. A later AD replaced this one: AD 2020-24-06. Comply with the one in force.
This AD applies to Textron Aviation, Inc. (type certificate previously held by Cessna Aircraft Company) Models 525, 525A, and 525B airplanes, certificated in any category, with Tamarack active load alleviation system (ATLAS) winglets installed in accordance with Supplemental Type Certificate (STC) SA03842NY.
We are adopting a new airworthiness directive (AD) for certain Textron Aviation, Inc. (type certificate previously held by Cessna Aircraft Company) Models 525, 525A, and 525B airplanes with Tamarack active load alleviation system (ATLAS) winglets installed in accordance with Supplemental Type Certificate (STC) SA03842NY. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as malfunction of the ATLAS. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, do the following actions in paragraphs (f)(1) through (3) of this AD.
(1) Before further flight after May 24, 2019 (the effective date of this AD):
(i) Revise the Operating Limitations section of the airplane flight manual (AFM) to prohibit further flight. You may insert a copy of this AD into the Operating Limitations section of the AFM to comply with this requirement.
(ii) Fabricate and install a placard in the cockpit of the airplane, in plain view of the pilot, with the following text: ALL FLIGHT IS PROHIBITED.
(2) In addition to the provisions of 14 CFR 43.3 and 43.7, the actions required by paragraph (f)(1) of this AD may be performed by the owner/operator (pilot) holding at least a private pilot certificate and must be entered into the aircraft records showing compliance with this AD in accordance with 14 CFR 43.9(a)(1) through (4) and 14 CFR 91.417(a)(2)(v). The record must be maintained as required by 14 CFR 91.417. This authority is not applicable to aircraft being operated under 14 CFR part 119.
(3) You may remove the AFM revision and placard required by paragraph (f)(1) of this AD after incorporating an FAA-approved modification. To obtain FAA-approval, the modification method must be approved by the Manager, New York ACO Branch, and the approval letter must specifically refer to this AD. To contact the New York ACO Branch, you may use the contact information found in paragraph (g) of 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.
