AD affects 36,000 Cessnas

Some 36,000 Cessna airplanes will be affected by a
new airworthiness directive that will require more rigorous,
repetitive 100-hr. or 12-month inspections of seat
rails, rollers and other related hardware. AD 2011-10-
09, which goes into effect June 17, adds steps to the
seat inspection procedures specified in an earlier directive
(AD 87-20-03 R2), which is being superseded.
FAA says these ADs—which apply to Cessna 150, 152,
170, 172, 175, 177, 180, 182, 185, 188, 190, 195, 206,
207, 210, T303, 336 and 337 aircraft—are designed to
prevent seat slippage or the seat roller housing from
departing the seat rail, which could cause a pilot to be
unable to reach all the controls, possibly leading to loss
of control of the airplane. Reports indicate that some
seats have slipped on their rails when the primary latch
pin for the seat is not properly engaged in the seat rail/
track. In other cases, the seat roller housing has departed
the seat rail. The agency estimates that this AD
will cost U.S. operators $85 per airplane to perform an
inspection and $395 to replace a seat rail, $280 to replace
a seat roller and approximately $100 to replace
miscellaneous parts. For more information, contact FAA
