In March 2020, Flying reported on an airworthiness directive focused on corrosion concerns on most models of the Cessna 210. On Tuesday, May 11, the FAA published a Notice of Proposed Rulemaking (NPRM) that may broaden the scope of that original AD to include both the Cessna 210R and N models, as well as all models of the Cessna 177 Cardinal. An NPRM is a preliminary announcement of the FAA’s intentions that could lead to a new AD. The agency will base its final decision to proceed onto a new AD after reviewing the user comments that the NPRM is requesting.
FAA’s NPRM On Corrosion Concerns Includes Additional Cessna Singles
Key Takeaways:
- The FAA has issued a Notice of Proposed Rulemaking (NPRM) to broaden an existing airworthiness directive (AD) for Cessna 210s to include 210R, N models, and all Cessna 177 Cardinal aircraft.
- This proposed AD is in response to a fatal 2019 Cessna T210M crash in Australia caused by wing spar failure due to fatigue cracking from a corrosion pit, along with other subsequent corrosion reports.
- The proposed AD would mandate visual and eddy current inspections of the carry-thru spar lower cap, requiring corrective actions such as protective coatings or immediate removal from service if cracks are identified.
