The work must strictly follow the procedures outlined in Cessna Service Information Letter SE 80-16.\n\n**Who is affected**\nOwners and operators of Cessna 188 \"Agwagon\" model aircraft with serial numbers between 18802851 and 18803522.\n\n**Deadline for compliance**\nThe repairs must be completed within 100 hours of flight time after 30 April 1980.\n\n**Why this matters**\nThe AN 155 brass turnbuckles may develop longitudinal cracks radiating from the ends.
