BALDWIN CITY, Kansas — McFarlane Aviation Products reports that after five years of certification effort, replacement Cessna seat roller housings are now FAA-PMA approved and in stock.

FAA AD 2011-10-09 requires the inspection of Cessna seat roller housings. If a housing does not pass inspection, it is mandatory to replac the housing.

These new replacement housings are precision machined and are improved with perfected dimensions for smooth installation and operation, according to company officials.

They also have an anodized finish for better wear and corrosion resistance.

Many of the housings are also available as an assembly with the locking pin bracket per-installed.

McFarlane recommends buying the assemblies when available because the rivet spacing on the brackets is very close, making them difficult to rivet without special tooling.

McFarlane stocks 27 different housing part numbers.

When asked about the difficulty in identifying the correct housings for a particular seat, McFarlane’s sales manager, John Cowan, explained: “We initially ran into the same confusion, but cured the confusion by developing a user friendly application flow chart. Extensive research went into developing this chart to ensure that our customers receive the parts that they need. This flow chart, along with pictures and key dimensions, are available on our website to aid our customers, and will be in our new catalog this spring.”
