There are issues with paragraph (g) of the propsed rule. Paragraph (g)(1) states to remove the ramp from the door per the Bombardier Modsum. Paragraph (g)(3) states again to remove the ramp, but adds the addition of corrosion inhibiter. This can cause confusion. I recommend removing the requirement in parapraph (g)(3) and have that paragraph only address the addition of the corrosion inhibiter. Suggested wording: (3) Apply corrosion inhibitor compound, in accordance with the applicable Bombardier modification summary package specified in Table 1 of this AD. Applying corrosion inhibitor compound is a terminating action for the requirements of this AD. Mike Donahue Mesaba Airlines Chief Engineer 612-794-9418 Office 612-940-2301 Cell
