## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas Model 717 series airplanes. This proposal would require repetitive inspections for cracking of the spoiler hold-down actuator supports located on the left and right wing rear spars; adjustment of the spoiler hold-down actuators; and replacement of cracked spoiler hold-down actuator supports with new supports. The proposal would also require replacement of all spoiler hold-down actuator supports, which terminates the repetitive inspections. This action is necessary to detect and correct as well as to prevent cracks in the spoiler hold-down actuator supports, which could lead to reduced spoiler hold-down capability, resulting in loss of the back-up protection of the spoiler float hold-down and unavailability of monitoring for an uncommanded spoiler movement. This action is intended to address the identified unsafe condition.
