L1000W DMS Notice

3/24/15

Dear AeroTech Dealers and Customers,

This notice is to inform you of an issue with the L1000W DMS motor. We have been made aware of a small number of case failures with early release lot numbers. Even though we have fired over 20 motors in development and QC testing without incident, we are issuing this notice as a precautionary measure.

RCS requests that the following L1000W DMS motors with the following lot numbers not be flown or sold. All motors are from the time period of
6/12/14 through 9/22/14 and do not include motors manufactured after 10/27/14.The lot codes are as follows: 101064,101074,102574,102974,102584, 102884,102294.

Some of you might wonder why it takes so long for a notice like this to be issued. First it takes time for a motor to enter circulation, secondly flyers seem to wait before flying them, thirdly news of a Cato starts out as a rumor before it finally hits my desk.

We continually monitor motor reliability (especially new ones) for issues developing in the field, many motor manufacturing processes are adjusted for safety and conformance without much fanfare. Occasionally motors like the L1000W make a bigger splash due to their size, new construction, and power. We have now developed a modification for the L1000W which we believe will improve its reliability. We expect to resume production and shipment of the L1000W in the near future.

We will replace any motor affected by this memo. Dealers are asked to inventory their stock and advise us of any motors they might have covered by this notice. Additionally customers possessing any of the above listed
motor(s) are asked first to contact their respective dealer for replacement, if that is not convenient then they can contact us directly.
We are sorry for any inconvenience this may have caused for our dealers and their customers, we thank you for your continued support.

Best regards,

Karl Baumann
