The FAA is correcting an airworthiness directive (AD) that published in the Federal Register. That AD applies to certain Bombardier, Inc., Model DHC-8-300 series airplanes. As published, a service information citation is incorrect. This document corrects the error. In all other respects, the original document remains the same.
Within 60 days after November 23, 2018 (the effective date of this AD): Revise the maintenance or inspection program, as applicable, to incorporate de Havilland Inc.

The initial compliance time for doing the task is at the time specified in de Havilland Inc. Dash 8 Series 300 Maintenance Task Card Task Number 5220/12 (“Servicing of Forward RH Emergency Exit Mechanisms”), dated March 15, 2017, or within 60 days after November 23, 2018, whichever occurs later.

Do all applicable replacements before further flight.
After the maintenance or inspection program has been revised as required by paragraph (g) of this AD, no alternative actions (e.g., inspections) or intervals may be used unless the actions and intervals are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (j)(1) of this AD.
