Plain English Summary

3/10 complexity

Amdt 1 to AD/W620/1 sets mandatory retirement times for Weatherly 620 wing components: the wing main spar lower cap assembly must be retired at 2,500 hours and the steel wing attachment fittings at 5,000 hours, effective 8 August 2002. It applies to all models and requires owners/operators to remove those parts by the stated times. CASA raised those limits based on a manufacturer fatigue report but will accept alternative inspection programmes if supported by analysis, test or service evidence meeting CAO 101.22.3.61 or FAR 23.573(b).

Amdt 1

Wing Fatigue Life Limitation 8/2002

Applicability: All Models.

Requirement: Retire the following items from service before the times shown:

Item	Life Limit
Wing Main Spar Lower Cap Assembly	2500 hours time in service
Steel Wing Attachment Fittings	5000 hours time in service.

Compliance: This Amendment becomes effective on 8 August 2002.

Background: As a result of a request for review of this Directive, the fatigue lives of the wing main spar lower cap assembly and steel wing attachment fittings have been increased in line with a fatigue substantiation report provided by the manufacturer.

The Authority is willing to consider submissions which substantiate that fatigue can safely be controlled by inspection beyond the life limits stipulated by this directive. This will require evidence, from analysis, test or service experience, that any proposed inspection program looks in the right places, in the right way, at the right times. Acceptable standards are CAO 101.22.3.61 or FAR 23.573(b).

The original issue of this Airworthiness Directive became effective on 18 November 1992.
