What to do
Operators of Boeing 717-200 airplanes must begin repetitive inspections of the lower aft skins, external doublers, and rear spar lower caps of both wings starting November 7, 2024. Any detected fuel leaks or cracks must be repaired following approved procedures, and inspection results must be reported to Boeing. Comments on the directive are accepted until December 9, 2024.
Summary
The Federal Aviation Administration's Airworthiness Directive 2024-21-01 addresses all Boeing Company Model 717-200 airplanes. This directive mandates repetitive inspections of the lower aft skins, external doublers, and rear spar lower caps on both wings due to reported cracks found during a fuel leak investigation. The inspections aim to detect fuel leaks or structural cracks to maintain airworthiness and safety.
What changed
This new airworthiness directive introduces mandatory repetitive inspections using visual and eddy current methods for specific wing components on Boeing 717-200 aircraft. It requires corrective actions and reporting to Boeing if any cracks or fuel leaks are found. This AD is an interim safety measure pending potential future rulemaking.
Why it matters
This directive is critical for aviation professionals as it addresses a structural integrity issue that could lead to catastrophic failure if undetected. Operators and maintenance teams must enhance inspection routines to identify cracks that existing programs might miss, ensuring continued safe operation of affected aircraft. Compliance reduces the risk of loss of control and enhances overall fleet safety.
