SEL-57-08 Wings - Model 210 Carry-Thru Spar One-Time Corrosion Inspection

Original Issue November 1, 2019

Revision 1 November 19, 2019

(Note: This SEL is provided for information. Please refer to AD 2020-03-16)


The carry-thru spar can develop corrosion and cracks.  Corrosion can propagate and lead to crack development.  A crack in the carry-thru spar can progress to a point that a structural failure of the carry-thru spar can occur, resulting in loss of airplane control and/or wing separation.

Non-compliance with this service letter may result in undetected corrosion and crack(s) in the carry-thru spar, which can result in structural failure of the carry-thru spar.


This service document provides instructions and repair criteria to do a detailed inspection of the carry-thru spar to inspect for corrosion and/or cracks.

See attached PDF. 


SEL-20-01 Listing of Nondestructive Testing Facilities

The purpose of this service letter is to provide a listing of nondestructive testing facilities which may be of help when accomplishment of nondestructive testing (NDI) is necessary on Cessna propeller model airplanes.
Cessna Aircraft Company recommends they you contact the specific facility directly to better understand the testing capabilities of that facility.
This service letter supersedes Cessna Service Newsletter SNL00-11.

Airworthiness Directive 2020-03-16 Textron Aviation Inc. Cessna 210 Wing Spar

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all Textron Aviation Inc. (Textron) (type certificate previously held by Cessna Aircraft Company) Models 210G, T210G, 210H, T210H, 210J, T210J, 210K, T210K, 210L, T210L, 210M, and T210M airplanes. This AD requires visual and eddy current inspections of the carry-thru spar lower cap, corrective action if necessary, application of a protective coating and corrosion inhibiting compound (CIC), and reporting the inspection results to the FAA. This AD was prompted by the in-flight break-up of a Model T210M airplane in Australia, due to fatigue cracking that initiated at a corrosion pit, and subsequent reports of other Model 210-series airplanes with widespread and severe corrosion. The FAA is issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective March 9, 2020.
