Plain English Summary

3/10 complexity

This airworthiness directive requires operators of Fokker F28 aeroplanes (except Mk. 0100) to inspect the elevator gust-lock housing and its support structure for cracks, following Fokker Service Bulletin F28/55-30, with initial compliance by 2 July 1993.

After a reported gust-lock housing failure during maintenance, the amendment allows operators to use Fokker SB F28/55-31 as a terminating action to end support-structure inspections (Note 1). The Civil Aviation Safety Authority issued the directive; operators pay for inspections and repairs.

Applicability: Model F28 (except Mk. 0100), all serial numbers.

Requirement: Inspect the elevator gust lock housing and support structure for cracks in accordance with the Accomplishment Instructions of Fokker Service Bulletin F28/55-30.

Note 1: Compliance with Fokker SB F28/55-31 constitutes terminating action for the support structure inspections.

Compliance: As specified in the Requirement Document with an initial accomplishment time of 2 July 1993.

The compliance time of this Directive remains unchanged. This Amendment is effective from 24 June 1993.

Background: The failure of an elevator gustlock housing has been been reported. This event occurred during maintenance after the cockpit control column was moved with the gustlock ON and the hydraulic system activated. The support structure on which the housing is mounted was also damaged. Amendment 1 is issued to reflect a revision of the related RLD AD which was revised to allow a terminating action in lieu of inspections of the gustlock support structure.
