Since this is on its now 

### 3rd approvalcycle, some comments. Since we have no US operators, why not require correction before further flight? As a possible explanation , consider the following under a differences heading : "This AD differs from the MCAI in that this AD requires compliance before further flight. Whereas, the MCAI requires compliance in accordance with a compliance interval identified in the MCAI. We have elected to require compliance before further flight [as a safety management initiative] or [in support of safety management](pick one) to ensure that should this product some day be introduced into our National Airspace System (NAS) that further compliance action will not be required prior to operation in the NAS.

### I concurrence . This ve rsion incorporates changes made on pages 3 and 7 (see revision marks) during grid review. The new l anguag e on page 7 , para (e)( 1 ), addresses the issue of not re-setting the compliance clock in a supersedure AD. The other changes in the compliance paragraphs , (e)(1 ), (2),and (3) are Paul's edits to better cite the operable NMSB paragraphs

. Thanks. --Drexel
