AMOC For Cessna 150/152s

During an annual inspection, technicians found the l/h elevator balance weight (p/n 96-610022-7) detached from its mount. The r/h elevator balance weight was found both broken and loose on its mount. The detached l/h weight was able to shift position inside the elevator and cause an out-of-balance condition. This damage appears to be caused by vibration.
