This Special Airworthiness Information Bulletin is to alert owners, operators, and maintenance

technicians and inspectors with a concern about cracked aft fin attachment fittings that affects all

series of Cessna Models 150/152, A150/A152, FA150/FRA150/FA152, and F150/F152 airplanes

that were produced from 1966 to 1986.

At this time, the airworthiness concern is not an unsafe condition that would warrant airworthiness

directive (AD) action under Title 14 of the Code of Federal Regulations (14 CFR) part 39.
