Boeing MD-11 Aeroplanes - Landing Gear Struts Extended Annunciation System - Installation
Summary
EASA Safety Information Bulletin 2016-03 is a safety information bulletin concerning Boeing MD-11 and MD-11F aeroplanes. It addresses the installation of the Landing Gear Struts Extended Annunciation System (SEAS), which provides pilots with visual alerts when the main landing gear struts are near or at full extension during landing. This system aims to improve pilot awareness of bounced landings and enhance landing safety.
What Changed
This bulletin introduces the recommendation to install the SEAS on Boeing MD-11 and MD-11F aircraft as per Boeing Service Bulletin MD11-32-093. It also highlights the inclusion of SEAS information in the Boeing MD-11 Flight Crew Operating Manual revision dated June 2015. The bulletin does not mandate installation but encourages operators to adopt the system along with updated training and maintenance procedures.
Why It Matters
The SEAS improves pilot situational awareness during landing by indicating the extension status of the main landing gear struts, helping to prevent bounced landings from escalating into more serious events. For operators and maintenance organizations, this system supports safer landing operations and aligns with updated Boeing maintenance and operating procedures. Compliance teams should note that this bulletin does not impose mandatory requirements but serves as a safety enhancement recommendation.
What To Do
Operators of Boeing MD-11 and MD-11F aeroplanes are recommended to install the Landing Gear SEAS following Boeing Service Bulletin MD11-32-093 or an equivalent tailored to their cockpit configuration. They should also incorporate enhanced pilot training using the updated Flight Crew Operating Manual procedures and follow Boeing's maintenance instructions for servicing main landing gear shock struts. There are no mandatory compliance deadlines specified in the bulletin.
