Glider Judging — Reviewing the ‘Setting a Line’ Rule

By David Taylor, IAC 435489

If you live east of the Mississippi, you won’t get much experience judging gliders. For some reason, it doesn’t seem to be much of a thing out east. In fact, the last time I saw a glider was at the 2019 U.S. Nationals. With few opportunities, it’s not unusual for judges to get fuzzy on the judging criteria between viewings.

That was the case during the 2021 U.S. Nationals when, due to a weather slip, a set of Sportsman gliders were added to the Unlimited Power Free Unknown-1.

We Can Rebuild It, Episode 17

By Rob Dumovic, IAC 436964

In Episode 17, I review what happened in Episode 16 — “Wiping down the airplane after a recent cross country, I notice something missing from the canopy rail. With only 12 days before I leave for Nationals, I’m not sure if it can be fixed in time.”

Fortunately Extra Flugzeugbau in Germany reached out with an approved plan to repair the canopy. In this case, the damage was determined to be superficial but being a certified aircraft the repairs must be to manufacturer standard. Read more ›

WAAC 2023


What Flies in Vegas Stays in Vegas

Except for the trophies … those leave with the champions

By Duncan Koerbel, WAAC 2023 Managing Director, IAC 437649

In October 2023, 70 of the world’s best Advanced aerobatic pilots will arrive in Las Vegas, Nevada, for the 15th FAI World Advanced Aerobatic Championships (WAAC). This occasion will be the first WAAC in the United States in 15 years.

What’s it all about? Every two years, the FAI holds the WAAC. Bids are submitted at its annual meeting, and the host venue is named. With support from the IAC, I traveled to Warsaw, Poland, in 2018 to bid. The United States was awarded the contest.

We are a go for flight from October 24, 2023, to November 4, 2023. Read more ›

Bret Davenport

By Zinnia Kilkenny, IAC 437244

I feel like I’ve been interested in aviation from birth. In my youth, I set up a table tennis in my bedroom and built giant airports out of Legos. I taught myself to fly RC aircraft as a kid (also how to rebuild them). Aviation was around me, but nobody in my immediate family was actively involved.

That said, my family has an interesting aviation heritage, but I didn’t know the extent until way after the initial hook was set. My grandfather flew F4U Corsairs in the Marine Corps in VMF-216, a sister squadron to VMF-214, the Black Sheep Squadron. Read more ›

MT Propeller Service Bulletin

MT Propeller has requested the FAA issue an airworthiness directive (AD) with the goal of locating and updating the small number of propellers that have not yet had MT SB 30 accomplished.

This only affects a very small population of selected MT props manufactured between late 2013 and 2014. These props may contain lag bolts in the blade roots from a run that did not meet the standards demanded by MT Propeller.

If your MT Prop s/n is between 13XXXX and 14XXXX, you need to check the SB 30.pdf document to see if your prop s/n is included. Learn more ›

Get Your Start

Get Your Start — Corey Gerilus

“Advice I’d give a new person just starting; right away find a coach,” said Corey Gerulis. “You need a mentor to critique you to make sure you are not just flopping around out there. Because when you go, it’s all about precision and if you didn’t have someone critiquing you and telling you how to do things properly you’re never going to progress.”

Enjoy this video with all its in-cockpit footage.
