AD/F100/37 Stabiliser Electrical Bonding 2/2000

Applicability: Model F.28 Mk.0070 and Mk.0100 aeroplanes.

Requirement: Remove the existing bonding jumper between the vertical and horizontal stabiliser and install two new bonding jumpers , Part Number FON9-1981-4CC5, in accordance with Fokker Service Bulletin SBF100-23-032 dated 22 September 1999.

Note: Netherlands RLD AD 1999-128 (A) refers.

This Airworthiness Directive becomes effective on 24 February 2000.

Background: The RLD has advised that following a lightning strike incident on a Fokker 100 it was found that the electrical bonding of the horizontal stabiliser did not meet the requirements of military standard MIL-B-5087B. MIL-B-5087B prescribes that each hinge joint should be provided with a bonding jumper.

This directive introduces new bonding jumpers to bring the electrical bonding of the horizontal stabiliser in line with MIL-B-5087B.
