If yes, list latest revision and attach a copy. Note that changes beyond the scope of the 

previously published NP RM will require a new notice. Contact the Directorate focal point

Instructions: Summarize all comments by issue (not by commenter) and provide your recommended resolution of 

each issue. All comments relat~ng to the same issue should be discussed together. Do not list all of the issues 

from one commenter together. If changes to the AD are required based on the comments received, explain why and 

describe in detail what change(s} you recommend. Reference FAA-IR-M-8040.1 C Chapter 9. 

ISSUE 1: Select one of the following: other 

lf other, explain: Difference between FAA AD and TCCA AD. 

Commenter(s): Etienne Rondeau-Garon 

What change to the AD action is requested? This AD requires inspecting the bearing bores for any 

pitting after cleaning the T /R link, while the Transport Canada AD requires inspecting for 

corrosion after cleaning the T /R link." The sentence needs to be clarified, but in any case the 

Transport Canada AD refers to the Bell ASB that requires inspecting for corrosion before and 

after cleaning which is no different than the FAA AD. "This AD requires inspecting the sealant 

with 1 OX or higher magnification, while the Transport Canada AD does not specify any 

magnification." Visual inspection of the sealant is sufficient. You can easily see if sealant was 

damaged or chipped without the 1 OX or higher magnification. "This AD does not require reidentifying the PIN of the link, whereas the Transport Canada AD does." The part was modified 

therefore it is not the same part anymore and requires a distinct means of identification. 

Furthermore unmodified part are not allowed to be re-installed. It the case were operators require 

to swap parts from one A/C to another, they will be forced to re-inspect the part as they will have 

no means to know if the AD was applied or not. The Bell ASB also requires re-identification of 

the part. Not mandating the re-identification could potentially induce confusion among operators.

If NO, we don't agree because We require inspecting the bearing bores for pitting after cleaning 

instead of inspecting for corrosion after cleaning. The cleaning process can remove corrosion but the 

cleaning process will not remove pits in the metal. We disagree that you do not need magnification to 

inspect the sealant. Corrosion can start in small openings where there is no sealant. We do not 

require re-identification of the part number with the letters "FM" because adding sealant to a part is 

not a modification (FM is Field Modified). Bell informed the FAA that they are going to change the 

part number. This ensures every pitch link receives the inspection ofthis AD.
