The inspection program was on-going for unmodified aircraft but no additional requirements were imposed.Amendment 2 updated the revision status of the referenced service bulletin and added Note 2. |
| Amendment 3 is issued to introduce the related new FAA AD to Note 1 of this Directive, with no change to technical content. |
