Re: FAA SAIB for Over Size Tires

Special Airworthiness Information Bulletin...

So what exactly does this mean to the guy who has Bushwheels mounted up on his bird? Not much apparently. Could something like this affect the willingness of the local FSDO to grant field approvals on larger tires?

From the SAIB text:

SAIB: CE-11-06 wrote:This [SAIB] alerts you, registered owners and operators of small airplanes, to follow established safety criteria, guidance, and data when modifying your aircraft with tires that are oversized compared to the original equipment...

At this time, the FAA has determined that this airworthiness concern is not an unsafe condition that
would warrant airworthiness directive (AD) action...

Investigation of a recent accident highlights the need for reminding operators of part 23
certificated airplanes that oversized tire modifications require analysis and substantiation as well as
periodic inspections to prevent unsafe conditions.

Great. Compass card, Seat belt tags, now is this an approved tire? Can you prove it to me?

Welllll, I'd think it might make some folks abit more...cautious.
An Ag sprayer takes a pretty hard beating even compared to many working bush planes.

I don't think this is so much aimed at approved installations as it is a warning shot aimed at the folks who think simply adding big tires a bushplane makes.
Hanging and flying an extra 20, 30, 40 pounds compared to stock wheels, and then rumbling across rocks and chuckholes is a different stress load than the original engineered requirements.
It certainly seems to me there are more tires than approvals flying right now.

Not too heavy-handed IMHO-- I took it just to be a "be careful out there" sort of thing, and maybe a nudge toward getting your fat tires approved if they're not already.

Re: FAA SAIB for Over Size Tires

Fortunately, no one on this forum is running oversize tires without legal approval.
Very responsible bunch here, good thing to know.
