SID extension by CASA

             CASA has provided an extension to the deadline for the completion of Cessna Supplemental Inspection Documents—or SIDs—on two groups of aircraft.The extension applies to Cessna 100 series aircraft used in charter and aerial work and Cessna 200 series aircraft used in private operations. SIDs compliance dates for both these operational categories have been extended by three months to 31 March 2016. The original CASA compliance date was 31 December 2015
        The deadline for the completion of SIDS inspections for private category Cessna 100 series aircraft remains 30 June 2016.SIDs inspections were developed jointly by Cessna and the United States Federal Aviation Administration (FAA) due to concerns relating to potential corrosion and fatigue damage to principal structural elements of the aircraft.
       The SIDs program, which complements existing scheduled maintenance, requires the additional detailed inspection of a range of structures including wing spars, wing attachment points, wing struts attachments as well as horizontal and vertical stabiliser attachment points.

PURPOSE: Provide current application of sealants, threading, lubricants, and                    adhesives. 
COMPLIANCE: During engine installation, maintenance, overhaul or                             component repair or replacement. 
MODELS AFFECTED: All CMI engine models operating with AVGAS fuel.

             Lubricating oils qualified for use in Continental Motors, Inc. (CMI) gasoline engines are required to meet Society of Automotive Engineers (SAE) specifications.
Recommended Oil Grade:
 • Above 40°F ambient air, sea level SAE 50 or                                                     multi-viscosity
 • Below 40°F ambient air, sea level SAE 30 or multi-viscosity
              NOTE: See  SIL99-1 (latest version) for preservation information.
 CMI recommends engine oil be drained and replenished every 25 hours of operation or 4 months for engines that incorporate an oil screen. Engines with full flow oil filters, either large or small, should have the oil changed every 50 hours or 4 months.

Supplemental Inspection No. 55-11-02

            FAA recommend that owners, operators, and maintenance technicians and inspectors visually inspect and confirm their findings using eddy current on the affected Cessna models utilizing aft fin attachment fitting, part numbers 0431009-1/-2/-3, for cracks and corrosion. This should be done repetitively at 100 hours intervals following inspection procedures described in the applicable Cessna SID located in the table of SIDs. Note that it may be beneficial for the inspection to be accomplished in conjunction with compliance to AD 80-11-04.
         FAA and Textron Aviation (Cessna) have been aware of cracking of the aft fin attachment fitting; and have previously issued a number of airworthiness publications to inform owner, operators, and maintenance technicians and inspectors. Cessna issued Service Bulletins (SE74-10 and SE78-62) in addition to the specific inspections noted in the referenced SID. Additionally, the FAA issued AC 43-16A, Aviation Maintenance Alert, Number 357, in April 2008 to remind inspectors to inspect the aft fin attachment fitting for cracks. Airplanes used for aerobatic use were noted to have a higher risk.
