What to do
Operators of Boeing 717-200 airplanes must perform a one-time general visual inspection of the inboard and outboard spoiler assemblies on both wings by July 29, 2021. If discrepancies are found, they must repair or replace the spoiler assemblies using FAA-approved methods or replacement parts conforming to Boeing specifications. Requests for compliance time extensions or alternative methods of compliance can be submitted to the FAA for approval.
Summary
The Federal Aviation Administration's Airworthiness Directive 2021-12-12 addresses all Boeing Model 717-200 airplanes. It mandates a one-time inspection of the left- and right-wing inboard and outboard spoiler assemblies to verify the correct splice bar and reinforcing doublers configuration. This directive responds to reports of incorrect splice bars installed and incorrectly identified parts that are not eligible for these aircraft.
What changed
This new airworthiness directive introduces a mandatory inspection and, if necessary, repair or replacement of spoiler assemblies with incorrect splice bars or missing reinforcing doublers. It also clarifies acceptable corrective actions, including repair approved by the FAA or replacement with serviceable spoiler assemblies following Boeing maintenance manual procedures.
Why it matters
This directive is critical for aviation professionals because incorrect spoiler assembly configurations can lead to failure of the splice bar, causing spoiler float and reduced aircraft controllability. Compliance ensures continued airworthiness and safety of Boeing 717-200 airplanes, helping operators avoid potential in-flight control issues and regulatory penalties.
