SavvyAnalysis has started a monthly newsletter for folks with SavvyAnalysis accounts (both Free and Pro), and it includes a monthly "puzzler" where we present some "interesting" engine monitor data and then challenge you to figure out what happened. Here's the puzzler for the June issue:

Some hints: This is a turbo with a MAP red-line at 35.5". The entire flight lasts only 11 minutes. After an uneventful pre-fligh runup, the pilot applies takeoff power (at approximately 6 minutes into the data) and very bad things happen. (The engine is being replaced.)

Once you think you've figured out what happened (or you give up), you can read my detailed analysis here:

But please try to figure it out for yourself first. That's the whole point.

We're going to try to do one of these every month.

BTW, if you'd like to receive the monthly newsletter -- which includes a monthly article by me about engine monitor data analysis, tips and tricks for using the SavvyAnalysis site to analyze your data, and the monthly puzzler -- just sign up for a free account at SavvyAnalysis.com and you'll automatically be on the list. Each newsletter includes an unsubscribe link in case you change your mind.

Enjoy!
