Missing or Improper Seat Stops in Cessna Models - SAFO 10016
Purpose: This SAFO reminds inspectors, operators, owners and maintenance technicians that type design seat stops are required to be installed on all seat rails to meet airworthy requirements.
Background: Missing or improper seat stops have been found on several Cessna models including 150, 152, 172 and 206. These seat stops are also found on Cessna models 303, 336 and 337; and all legacy (pre-1987) single-engine Cessna models 170, 175, 177, 180, 182, 185, 188, 190, 195, 205, 207 and 210. Cessna has identified seat stops as an important piece of equipment required for safety by inserting a warning note into their service manuals to ensure that seat stops are installed in the proper positions on the rails for each seat.
Discussion: Improperly installed, worn or incorrect seat stop installations could allow the pilot and or co-pilot seats to depart the rails during critical phases of flight, such as take-off and landing. The seat stops need to be inspected at regular intervals for condition and proper installation to ensure the continued airworthiness of the seat stops. The Cessna service manual recommends inspection of seat stops at the 100 hour/Annual inspection, although not all of the Cessna service manuals provide instructions that specifically address inspection of the stops for condition, proper location or that the stops are approved parts.

Email this pageBob's comment couldn't be more appropriate. In 1992 took my commercial pilot check ride on a 172 and during take off my seat was derailed backwards causing me to loose control, obviously the examiner took over. He allowed me to recover and secure my seat in order to carry on. On the ground, briefly told me about this notorious condition that brought up a major lawsuit against the manufacturer. Cessna Aircraft is probably the most successful aircraft builder in history and they simply make quality products. My point here, is to encourage people to investigate about this issue and take positive action. Lets not get complacent.

We had to renew the spindleblocks on all 4 seats last year on our 2001 Cessna T182T. Another Cessna 182 had experienced a seat derailing as one of the spindles broke during T/O or landing. According to Cessna this was caused by a heavy (more than 120 kg) pilot/passenger.

Where can I can drawings, diagrams, and/or instructions for inspecting the seat stops myself in addition to the annual?

Where do I get some diagrams or instruction for reviewing my 69 Cessna's seats myself?

I was a witness to a Cessna seat derailing. We were holding short of the runway where a 172 had just landed. We heard the engine spool up to continue the touch and go when the person in the left seat tumbled backward and the 172 veered off the runway and passed about 20 yards in front of us heading for the FBO building at full power. The 172 collided with a row of parked aircraft on the apron destroying the 172 and another aircraft. Fortunately the two people in the 172 extricated themselves from the wreckage without serious injury. A surprisingly lucky result.
