Commonwealth legislation
This Act has been repealed and is no longer in force. It is retained for historical reference.
This AD requires operators of certain Cessna 172/175/R172 models to inspect seat adjustment mechanisms—checking rollers, washers, and axle bolts/bushings for flat spots, wear, or binding; ensure free movement; clean binding parts; and replace damaged rollers or worn washers before flight. Do not lubricate these parts.
It affects owners/operators of the listed aircraft and matters because stuck or degraded seat adjustments can impede proper pilot seating and compromise safety.

(d) Visually inspect seat rollers for flat spots. Ensure all rollers and washers turn freely on their axle bolts (or bushings if installed) and move freely on the seat rails. Replace rollers having flat spots and any worn washers prior to further flight. If there is any binding between the bores of the rollers, washers, and axle bolts (or bushings if installed), remove, clean, and reinstall these parts prior to further flight.
Note: Do not lubricate rollers, washers, axle bolts or bushings as the lubrication will attract dust and other particles which can cause binding.
