Cessna 310 Series Aeroplanes AD/CESSNA 310/33 Amdt 2 Wing and Airframe 13/2006

Applicability: All Cessna model 310 series aircraft 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 before 19,200 hours time-in-service or 29,500 flights, whichever occurs first.

2. Retire from service the whole airframe at 38,400 hours time-in-service or 59,000 flights, whichever occurs first.

Note 1: While Requirement 1 excludes the carry-through and its attach 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 on Cessna 402Cs, which are similar.

Note 2: Deleted.

Note 3: If there is no record of time for a flight, assume 0.5 hours. Compliance: This Amendment becomes effective on 21 December 2006. Background: This Airworthiness Directive retires structure from service, before dangerous fatigue cracks are likely, if aircraft are not on Cessna's SID program.
