Requirement: | Action in accordance with the requirements of EASA AD 2008-0020. Note: Fokker Service Bulletins SBF100-11-025 Revision 1 and SBF100-52-086 original issue, or later EASA approved revisions, refer. |

Background: | Following a red illuminated “DOOR NOT LOCKED” status light indication on the door lock indication panel after lift off, the cabin crew operated the door lock handle. This resulted in inadvertent opening of the downward-opening passenger door during flight. Fokker 70/100 Service Letter 272 informs operators not to operate the door lock handle after the aircraft has started to move or before it has come to a complete standstill. This Directive requires installation of a warning placard and a one-time inspection of the clearance between lever part number A26997-003 and the Up-Limit Switch. |
