EASA SIB SAIB-2024-02
Wing Spar - Inspection
Summary
Special Airworthiness Information Bulletin SAIB: 2024-02 is an FAA informational bulletin addressing potential cracks and hole-quality issues in the wing rear attach beam assembly of Revo Incorporated Model Colonial C-1, Colonial C-2, Lake LA-4 series, Lake Model 250, and Lake 270 Turbo Renegade aircraft. The bulletin highlights inspection areas and provides guidance to owners, operators, and maintenance personnel to identify and address these concerns. This bulletin is not a mandatory directive but serves as a safety alert.
What Changed
SAIB: 2024-02 introduces awareness of potential cracks and elongated bolt holes in the wing rear spar web and attach fittings of specified Lake amphibious aircraft models. It provides detailed inspection recommendations and reporting procedures to detect and manage these issues. This is a new informational bulletin rather than an amendment to existing regulations.
Why It Matters
This bulletin matters because cracks and hole elongation in critical wing spar components can affect the structural integrity of the aircraft, potentially compromising safety. Aviation professionals, including operators and maintenance organizations, need to be vigilant in inspecting these areas to prevent undetected damage. Early detection and proper reporting help maintain airworthiness and prevent costly repairs or incidents.
What To Do
Owners and operators should perform thorough inspections of wing attach hardware, fittings, and the aft beam assembly during routine maintenance or after any incident causing unusual wing stress. Any findings of cracks, gaps, or elongated holes must be repaired or replaced following manufacturer instructions or FAA-accepted practices. Inspection results should be reported via the FAA Service Difficulty Reporting System or directly to the Lake Amphibian Club. No specific compliance deadlines are stated.
