MTD-04-2025 - Replacement of all plastic control linkage rod end connector washers with metal washers
During an inspection of an early Rans S6, all plastic washers between the bolt and bearing of the flap and aileron control linkage rod end connectors were found to be split or missing. This issue is identified in Rans’ service bulletin 012390-03.
Â
As plastic washers are susceptible to failure due to wear and embrittlement, this MTD is raised to mandate the replacement of all plastic control linkage rod end connector washers with metal washers. These washers prevent the rod end from disconnecting in the event of bearing failure.
Â
The washers fitted must be larger than the diameter of the bearing. Refer to here for a diagram.
MTD-04-2025 can be found here and is found below.
Note: Do not re-use nyloc or other self-locking nuts if their locking ability has become compromised.
