The FAA feels that the airworthiness concern detailed in SAIB-CE-17-12 doesn’t warrant an airworthiness directive at this time.

The FAA has issued a Special Airworthiness Information Bulletin (SAIB CE-17-12) to inform aircraft owners/operators, maintenance technicians, and inspectors of an airworthiness concern “for the potential of loose bolts at the elevator attach points” on certain Cessna 150 and 152 airplane models listed below.

More Details On SAIB CE-17-12

The FAA notes that they received a report, through the Safety Difficulty Reporting (SDR) system “of the elevator hinge bolt backing out on Cessna Model 150 airplanes.” This, in turn, allowed the elevator to separate from the horizontal stabilizer in-flight “which resulted in reduced controllability in the pitch axis.

The agency said that the main issue identified were:

  • Excessively worn attach hardware
  • Use of incorrect attach hardware

They also note that corrosion may have been a contributing factor is some instances and that after further reviewing SDR’s all the way back to 1979, they found seven similar reports. The agency says that the design used in attaching the elevator to the airplane is common among the models listed in this table:

Model S/N
150 617, 628, 644, 649, 17001 – 17999, 59001 – 59018, 15059019 – 15079405
A150 A15000001 – A1500734
A-150 A-1501001 – A-1501039
A-A150 A-A1500001 – A-A1500009
F150 F150-0001 – F150-0529, F15000530 – F15001428
FA150 FA1500001 – FA1500120
FRA150 FRA1500121 – FRA1500336
152 15279406 – 15286033
A152 A15200735 – A15201049
FA152 FA15200337 – FA1520425
F152 F15201449 – F15201980

The FAA recommends performing the inspections that are outlined in the Cessna supplemental inspection document (SID) 55-10-01, a copy of which can be found here. If either worn or incorrect hardware is found, the agency further recommends replacing it according to the instructions provided in the SID.

In 1966, the venerable 150 received a makeover, including the addition of a wildly popular slanted tail. The restyle paid off, resulting in sales of 3,000 Cessna 150s in 1966 alone. In 1970, the Cessna 150 Aerobat hit the market, gaining popularity as an aerobatic training aircraft. Many 150 Aerobats still serve as sport aircraft. Finally, the stage was set for the two-seater Cessna 152 [Click to read more…]
