This Service Bulletin (SB) is a follow-up to the SB issued on 27-May-2016 alerting Alta owners who purchased their unit after 18-March-2016 date to discontinue flight operations immediately.

RECOMMENDATIONS

Freefly is continuing to investigate the cause of two infield failures of Alta 8 motor mounts, and we are issuing a mandatory recall of all Alta 8 units for repair. Please discontinue operation of your Alta 8 immediately.

Freefly Customer Support will reach out to all affected owners directly and arrange shipping information and estimated repair times.

Please wait for further communication from Freefly Customer Support with details on the RMA process before returning your Alta 8.

The post SB13B Motor Mount Failure (2016-05-31) appeared first on Freefly Systems.

These motor mounts are believed to be susceptible to material fatigue due to incorrect machined geometry, which ultimately led to calamitous failure of the motor mounts during operation.

There have been no Alta 6 infield failures related this issue, though it is possible that Alta 6 machines shipped after 18-March-2016 were built with motor mounts that are outside of spec.

Freefly is working with our machined parts supplier to attempt to narrow the timeline and better define the units that may have been built with these motor mounts.

At this point we believe this issue may necessitate all Alta 8 user to return their unit to Freefly for inspection, repair, and / or replacement of parts in question.

RECOMMENDATIONS

Freefly recommends all Alta operators who purchased their Alta after 18-March-2016 to immediately discontinue flight operations until a modification that resolves the issue is implemented. We will continue to investigate the issue over the weekend and provide an update on Tuesday (May 31st, PST) prior to close of business.
