All Tecnam P2008 aircraft (i.e. certificated, LSA and microlight aircraft) fitted with a fuselage extrusion P/N 28-2-1095-1.
This Continuing Airworthiness Notice (CAN) is issued to bring attention to defect reports submitted to the CAA of finding corrosion in the attachment lugs of fuselage extrusion P/N 28-2-1095-1 on five P2008 aircraft.
For further details of the location of the corrosion found, refer to the photos in this CAN.
This CAN is prompted by five occurrences reported to the CAA of finding corrosion in the attachment lugs of the fuselage extrusion P/N 28-2-1095-1. The fuselage extrusion attaches both the LH and RH wings aft spars to the fuselage. The corrosion found in the bolt attachment lugs is intergranular, and had advanced significantly to require replacement.
The corrosion was found during wing removal for an unrelated issue. The corrosion appears to have occurred in areas where the protection paint finish was not damaged and also not in areas of dissimilar metal contact (e.g. from the attachment bolts).
Operators should follow manufacturers recommendations for corrosion control applicable to operation in high salt/high humidity environments. In the case of Tecnam aircraft, the manufacturer recommends applying anti-corrosive to wing attachments every 12 months.
The CAA strongly recommends that operators and maintainers of Tecnam P2008 aircraft inspect the attachment lugs of fuselage extrusion P/N 28-2-1095-1 for defects and corrosion.
If any defects are found accomplish appropriate corrective actions before further flight.
CAA requests that operators and maintenance providers report any cracks, or damage found, via the occurrence reporting process: https://occurrencereporting.services.aviation.govt.nz(external link)
Tecnam has been notified of these findings. Refer to the photos below for examples of typical corrosion found.
This CAN is considered to be an interim action and further CAN, or AD action may follow.
