Cirrus Design Corporation (CDC) SR20 and SR22 Reason for Airworthiness Concern:
Possible serious or fatal injury due to loss of door while in flight Date: April 19, 2007 FAA Description of Airworthiness Concern (Who, What, Where, When, How? Attachments: RA and appropriate data)
This concern originated from notification by CDC of a door that separated from a Cirrus airplane while in-flight. The probable cause of the door separation was the failure of the lower rod end (a component of the lower door hinge). The possibility of bent rod ends was previously identified by CDC in owner service advisory SA 06-08 (attached). We have been advised by CDC that the design of the rod ends has been revised. A Service Bulletin for field installation of the new rod ends should be available within the next two weeks.
Request for Information (Proposed Alternate Inspection/Repair Procedures, Cost Impact, Etc. Note: Any comments or replies to the FAA need to be as specific as possible. Please provide specific examples to illustrate your comments/concerns.):
Please review the attached Service Advisory and provide us with additional information, which may affect the airworthiness action taken by the FAA. This includes comments regarding the CDC service advisory and any additional findings, accidents/incidents, or service difficulties pertaining to this airworthiness concern.
