So was it 15%, or 25%? I'm confused. Or maybe 1.5%. Doubtful.

What you are is pedantic. 1out of 4 or 1 out of six. It was somewhere in that range.

Maintenance practices ebbed and flowed between bases. As did the flying. Some planes flew night runs only to get back in time to fly a day run to the outstation resulting in lengthy deferrals before they could find decent hangar times at an AMF base. I’m pretty positive I flew 191AF with something like 10-12 deferrals on it the day after another base kindly traded it to us. I know 188 approached that number and was known as sky pig.

I'm just a data guy, so show the data.

Yeah, I didn’t highlight or asterisk my flights with deferred NWS steering. It was a common occurrence. I didn’t highlight deferred pressurization either. I’m pretty sure that was twice. SRL once. Engine failure once. Precautionary shut down once.

You’re just going to have to live with it data guy. I’m not running down AMF. I’m still in touch with my former ACP, and would recommend anyone go there to cut their teeth. But the fact of the matter was that I flew the planes with deferred nose wheel steering quite often in my 2 years and change in the type. A lot of that had to do with the flying being done. Some of it had to do with trading out sick birds that lived in outstations or the cast offs from other bases when trades occurred.

You should maybe consider that something can be true just even though it doesn’t jive with your personal experience.

No one remembers a 0.25% or 1.5% deferral rate. But yeah, 10%+ you start to notice. This called an anecdote. Thanks for sharing FNFGO. tbmpilot is an idiot. Seriously - if you want an actual statistic you need more than a % - you need things like a confidence interval. And does someone fly enough to make edge limit statistics like 0.25% reliable? generally no. You need a ton of data to start doing reliable edge limit stats. (ie, to distinguish between .125% / .25% / .5% (all a factor of 2 different). Much easier to figure out mid and other ranges (50% / 100%) - also a factor of two.

I’ve got about 400 hrs in AMF metroliners and never had NWS deferred and never did a AWI takeoff. Maybe it’s a base thing cuz something major like that was usually fixed quickly by our MX crews at BFI.

Why are we even discussing a metroliner when it was a 1900 anyway?
