Sur plusieurs « CESSNA » ils ont trouvé des fissures près de l'attache inférieure des haubans (strut) produit jusqu'en 1986 ou 1987. Le « Service Bulletin # SEB95-19 » s’applique aux 172, 182, 20s, 207 et certain 210. Même si l’application ne débute qu’aux 172 N et suivant, 182 E et suivant, 210-5 et suivant, à mon avis ça ne serait pas un luxe de le faire sur les modèle avant l’application?
La FAA est au courant depuis 1995 et « CESSNA » avait sortie un « Service Bulletin en 1995 portant le # SEB95-19 ». CESSNA demandait dans le bulletin une inspection toutes les 1,000 heures (de vols). La FAA considère de réduire le temps entre les inspections. Si une ou des fissure(s) sont trouvé un ensemble (kit) de réparation est disponible.

FAA: Possible Structural Issues In Vintage Cessnas
By Geoff Rapoport
Cracks near the wing strut attachment were found in several Cessna 207s belonging to a single operator, leading the FAA to request information from owners and operators to determine how many aircraft have similar damage. The cracks could cause wing deformation leading to unflattering changes in flight characteristics, and, although unlikely, could cause wing failure in aircraft with extremely advanced cracks, according to the FAA. Cessnas with wing struts produced up to 1986 are potentially affected. The FAA has been aware of the issue since at least 1995, when Cessna released a service bulletin (SEB95-19) requiring inspection of the lower forward doorpost every 1,000 hours and installation of a reinforcement kit if cracks are found. The request for additional information through this Airworthiness Concern Sheet suggests the FAA is considering more frequent inspections.
When operators perform the required inspection, the FAA is asking owners/operators to send the results, along with total airframe hours, to the Wichita Aircraft Certification Office. The agency is also seeking information on the time required to perform the inspection to assess the cost of more frequent inspections. The 1995 service bulletin estimates 1.5 man-hours to perform the inspection, which requires removal of the upholstery, heater ducts and floorboard inspection covers near the lower forward cabin doorpost. Cessna budgets an additional 24 man-hours to install the reinforcement kit, if needed.
