EASA SIB CE-09-10
Cessna Seats Secondary Stop Installation
Summary
The Special Airworthiness Information Bulletin SAIB: CE-09-10 is an FAA informational bulletin addressing the availability of secondary seat stops for pilot and copilot seats on various Cessna aircraft models including 170, 172, 182, 206, 210, 337, and others. It highlights ongoing concerns with seat latch pin engagement that can lead to seat slippage and potential loss of airplane control. The bulletin informs operators about service bulletins issued by Cessna for installing secondary seat stops and inspecting certain reel assemblies.
What Changed
SAIB CE-09-10 introduces the availability and recommended installation of secondary seat stops for pilot and copilot seats to enhance safety beyond existing airworthiness directives. It also addresses inspection and possible replacement of certain reel assemblies (P/N 505590-401) included in some secondary seat stop kits. This bulletin does not mandate compliance but provides updated safety recommendations and references related Cessna service bulletins.
Why It Matters
This bulletin is important for aviation professionals because seat slippage due to latch pin failure has caused accidents and fatalities in Cessna aircraft over the past decades. Installing secondary seat stops and inspecting reel assemblies can prevent seat movement that might compromise pilot control. Operators, maintenance personnel, and compliance teams should be aware of these recommendations to enhance flight safety and reduce risk of accidents.
What To Do
Owners, operators, and maintenance technicians should install secondary seat stops on pilot and copilot seats if not already installed, following Cessna Service Bulletins SEB07-5 R1 and MEB07-1 R1. For aircraft with secondary seat stops installed, inspect the P/N 505590-401 reel assemblies per Cessna SEB07-8 and MEB07-2 and replace any defective parts. There is no mandatory compliance deadline specified in the bulletin.
