Cessna (including Reims Aviation) - Missing or Improper Seat Stops
Summary
The Safety Alert for Operators (SAFO) 10016 titled "Cessna (including Reims Aviation) - Missing or Improper Seat Stops" addresses the requirement for type design seat stops on seat rails in various Cessna aircraft models. Affected aircraft include Cessna models 150, 152, 172, 206, 303, 336, 337, and legacy single-engine models such as 170, 175, 177, 180, 182, 185, 188, 190, 195, 205, 207, and 210. The document highlights the importance of proper seat stop installation to maintain airworthiness and safety during critical flight phases.
What Changed
SAFO 10016 introduces a reminder and guidance for inspectors, operators, owners, and maintenance technicians to ensure that type design seat stops are installed correctly on all seat rails of the specified Cessna models. It emphasizes the need for regular inspection of seat stops for condition, proper location, and use of approved parts, as recommended in Cessna service manuals.
Why It Matters
This SAFO is critical because improperly installed, worn, or incorrect seat stops can cause pilot or co-pilot seats to slide off their rails during takeoff or landing, posing a significant safety risk. Aviation professionals must ensure seat stops are maintained to prevent potential accidents and to comply with airworthiness requirements. Regular inspections help maintain the structural integrity and safety of the seating system.
What To Do
Operators and maintenance personnel should inspect seat stops at scheduled intervals, such as during the 100-hour or annual inspections, verifying that seat stops are properly located, undamaged, and are the correct parts as identified in the parts catalog. Any bent, cracked, or worn seat stops should be replaced promptly to maintain airworthiness. No specific compliance deadline is stated, so adherence should be immediate and ongoing.
