Plain English Summary

3/10 complexity

This Airworthiness Directive requires owners/operators of Cessna 210 series aeroplanes with cantilever (unstrutted) wings to access and inspect the wing main spar carry‑through forging for corrosion and to carry out any repairs under a scheme approved by the aviation authority. Inspections start at 10 years from manufacture and repeat every 6 years (or every 12 years if an approved corrosion protection scheme is used). The directive responds to reported corrosion that in some cases affected wing structural integrity.

Amdt 2

Wing Main Spar Carry-Through Section 4/2001

Applicability: All models with cantilever (unstrutted) wings.

Requirement: 1. Gain access to the upper and lower surfaces of the wing carry through forging.

Inspect the whole wing carry-through forging for any indications of corrosion. Repairs to the wing carry-through forging shall be in accordance with a scheme approved by the Authority.

Compliance: For the initial inspection, upon accumulating 10 years time in service since manufacture. Thereafter at intervals not to exceed 6 years, or, if the spar carry- through has been subjected to an approved corrosion protection scheme, at intervals not to exceed 12 years.

This amendment becomes effective on 19 April 2001.

Background: There have been reports of corrosion in the wing spar carry-through forging on a number of aircraft. In two cases the corrosion was sufficiently advanced to adversely affect the structural integrity of the wing.

Amendment 1 reflected the reported results from the initial issue of this Directive which enabled a reduction in the initial compliance time and an extension of the repeat inspection period.

Amendment 2 is issued to clarify the compliance requirements from the previous issue. This amendment does not impose any further technical requirements.
