Fokker F100 (F28 Mk 100) Series Aeroplanes AD/F100/68 Passenger Service Unit, Speaker, Oxygen 7/2005 and Blind Panels Attachments

Applicability: Model F28 Mk 0100 aircraft, serial numbers 11244 through 11486, 11488 through 11491, 11496, 11498 through 11502, 11504 through 11507, and 11511 through 11527; except aircraft modified in accordance with Fokker SB F100-25-070. Requirement: Install two additional cable ties to each attachment bracket of Passenger Service Unit, speaker, oxygen, and blind panel assemblies in accordance with Part 2 Accomplishment Instructions of Fokker Services SB F100-25-103, dated 15 March 2005, or later CAA-NL approved revision.

Note: Netherlands CAA AD NL-2005-005 refers. Compliance: Within 2 years after 7 July 2005. This Airworthiness Directive becomes effective on 7 July 2005. Background: During an off-field emergency landing, the high inertia forces caused the rails from which the passenger service unit, speaker, oxygen, and blind panel assemblies are suspended to come loose from their brackets and fall on the backrests of the passenger seats throughout the cabin. Although in compliance with CS (JAR) 25.561(b)(3), inertia forces which exceed those of the certification requirements, or a dynamic deformation mechanism, could result in further incidents of panel detachments. This Directive requires the installation of additional cable ties to passenger service unit attachment brackets.
