The bane of statistics! As noted it's impossible to determine statistical power without some alternative hypothesis, but generally the...

Absolutely. The data are certainly in support of inspections. What they do not support is (a) an initial period before inspection longer...

CALCULUS ALERT: The failures are cumulative in that each hour could cause cracking that fails the inspection later. The cracking (under...

No. The probability of rolling snake eyes at least once in N trials increases as N increases (which the graph shows), but the...

Imagine that every hour you fly you roll a 500,000-sided die, and if it lands on 1 the spar fails. Would you (a) check the plane at some...

When everybody freaked out and ran to do these tests even on a voluntary basis (aka if the factor hours didn't call for one), there was...

The 450B is fantastic. I recently had mine re-wired for stereo and the aural separation makes it much easier to handle handle two comms...

The worrisome thing will be when spars that passed ECI fall off.

Unfortunately this isn't a question the data can necessarily answer. We can say that many more spars failed ECI than fell off.

It's always about story telling. Another quote attributed to Einstein that rings true but probably wasn't really said by him: "I've...

Interesting point. Are you able to see evidence of duplicate report lines in the tables from reports that you're familiar with?

Interestingly, the only 2020 aircraft to be inspected had 3300 hours, all commercial, and the right front bolt hole failed.

Let's look at what the data tell us. Here's failure rate with CIs by year (in 5-year buckets): Note: this does not account for the...
