Fairbanks Morse Engine 701 White Avenue Beloit, WI 53511 (iv) Nature of the defect or failure to comply and the safety hazard which is created or could be created by such defect or failure to comply.
Nature of defect:
In some 2301A controls, 1nF capacitors may have been loaded in place of 150pF capacitors. This could affect circuitry controlling the units crystal, speed signal and reset dynamics, and power supply operation.
FM Notification Report Serial Number 22-02 Issued 2 Nov 2022 Fairbanks Morse 10CFR 21.21 (d)(3)(ii) Notification FM form BF5548 Page 2 of 3 Safety hazard which could be created by such defect: This issue can prevent affected 2301A controls from starting up or may lead to unscheduled shutdown of affected controls. It can also prevent the prime mover from obtaining a stable speed response, causing it to hunt or overspeed. In some cases, the RESET potentiometer may run out of range to adjust the unit for stable operation or desired prime mover speed response, resulting in prime mover performance outside of specification limits.
(v) The date on which the information of such defect or failure to comply was obtained.
Fairbanks Morse concluded a substantial safety hazard may exist on 27 October 2022 (vi) In the case of a basic component which contains a defect or fails to comply, the number and location of all such components in use at, supplied for, or being supplied for one or more facilities or activities subject to the regulations in this part.
