Airworthiness Directive · Amendment 39-13758 · Short Brothers Model SD3 Series Airplanes
Short Brothers Model SD3 Series Airplanes
All Model SD3 series airplanes, certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to all Short Brothers Model SD3 series airplanes, that requires installing a new warning annunciator light on the central warning panel and revising the Normal Procedures Section of the Aircraft Flight Manual to provide the flightcrew with procedures related to the new light. This action is necessary to prevent an engine shut-down in icing conditions, which could result in loss of control of the airplane and consequent injury to flightcrew and passengers. This action is intended to address the identified unsafe condition.
To prevent an engine shut down in icing conditions, which could result in loss of control of the airplane and consequent injury to flight crew and passengers, accomplish the following:
(a) Within five months after the effective date of this AD, do the actions specified in paragraphs (a)(1) and (a)(2) of this AD.
(1) Install a new warning annunciator light on the central warning panel in accordance with the Accomplishment Instructions of the applicable Shorts service bulletins listed in Table 1 of this AD; and
(2) Revise the Normal Procedures Section of the AFM by inserting a copy of the applicable pages of the Shorts AFM document listed in Table 1 of this AD, per the Accomplishment Instructions of the applicable Shorts service bulletin listed in Table 1 of this AD.
