EASA SIB CE-14-11R1
Cessna 310, 335, 340, 401, 402, 404, 414, 411, 414, 421, 425 and 441 series Aeroplanes — Nose Landing Gear Trunnions
Summary
The FAA Special Airworthiness Information Bulletin SAIB: CE-14-11R1 addresses an airworthiness concern for Cessna 300 and 400 series airplanes, specifically models 310, 335, 340, 401, 402, 404, 411, 414, 421, 425, and 441. It alerts owners, operators, and maintenance personnel to inspect the nose landing gear trunnions for cracks to prevent potential failure during landing, which could cause significant damage and occupant injury. This bulletin is informational and does not mandate regulatory action.
What Changed
This revision of SAIB CE-14-11R1 removes the reference to the Reims 406 aircraft, clarifying that it uses a different trunnion part number and is not covered by the Cessna Service Bulletins MEB88-5 and CQB00-3. The bulletin continues to recommend inspections and replacements based on existing Cessna service information but does not introduce new mandatory requirements.
Why It Matters
This bulletin is important for aviation professionals because it highlights a known risk of nose landing gear trunnion cracks in aging Cessna 300 and 400 series airplanes, which could lead to gear failure and damage during landing. Operators and maintenance teams benefit from this awareness to ensure proper inspections and maintenance are performed, reducing the risk of accidents and costly repairs. It also reinforces the use of existing service bulletins to maintain aircraft safety.
What To Do
Owners, operators, and maintenance personnel of affected Cessna models should comply with Cessna Service Bulletin MEB88-5 Revision 2 for models 310 through 421, and Service Bulletin CQB00-3 for models 425 and 441, to inspect and replace nose gear trunnions as necessary. There is no mandatory compliance deadline, but timely inspections are recommended to prevent failures.
