The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.

Cessna 400 Series Aeroplanes
AD/CESSNA 400/40 Amdt 14  Wing and Airframe  13/2006

Applicability:  All aircraft of the models listed in the Retirement Schedule below which are not maintained to Cessna's SID program.

                (See Airworthiness Bulletin 02-007 on www.casa.gov.au)
Requirement:       1. Retire from service the wing main spar lower cap and the upper and lower attach fittings at the times shown in the Retirement Schedule below.  Retire the parts when they reach the hours or flights, whichever occurs first.

                   2. Retire from service the whole airframe at twice the hours or flights, whichever occurs first, shown in the Retirement Schedule below.

                Note 1:  While Requirement 1 excludes the carry-through and its attachment fittings, we recommend replacement at the same time - or Cessna's SID program, which has found cracks in the carry-through and its attach fittings.
