Liberty Aerospace has come up with a solution for a problem with doors on its two-seat XL-2 aircraft that may pop open in flight. The FAA said it is “not an unsafe condition that would warrant airworthiness directive action.”
The FAA released a special airworthiness information bulletin explaining that “there have been six occurrences of a door opening in flight on Liberty XL-2 airplanes. In all six cases, the pilot has been able to land the airplane safely and there is evidence the door was not properly latched before takeoff.”
The two-passenger/crew entrance doors on the XL-2 are gull-wing type doors with hinges on the top edge of the doors. If a door is not properly closed and latched prior to flight, the air flow during flight could cause the door to open. The open door could separate from the airplane and could cause damage to the airplane empennage or injure someone on the ground.
Liberty Aerospace issued Service Bulletin SB-09-003 on Dec. 15, 2009, to provide a new rear tapered door pin for each door and to publish airplane flight manual revisions. The new door pin allows the door to be more easily latched. The flight manual revisions include additional notes and warnings in the checklists for the pilot to check the engagement of both the front and rear door pins before takeoff.
The FAA “recommended” that owners follow the advice in the service bulletin.

As the cold weather chills AOPA’s Headquarters in Frederick, many of us are inside generating new resources for flying clubs.
In my house, every Friday night is “Movie Night.” While the movies are rarely educational (I don’t think I learned anything from the Lego Movie), we look forward to the weekly opportunity to spend time together. Why not use the same concept for your Flying Club (with the addition of education, of course)?
AOPA Flying Club Manager Kelby Ferwerda posted the following on the AOPA Flying Club Facebook Page: “Recently I’ve talked with quite a few Flying Clubs about maintaining social activity through the cold winter months. Some clubs host Holliday Parties, others have Potluck Movie Nights. What does your club do to keep members involved during the chilly months?”
